I'm trying to update the content of the body property of an activitymimeattachment. I've tested several methods in a plugin, as well as the webapi. Somehow the property is not updated.
A sample webapi call:
url: https://tenant.crm4.dynamics.com/api/data/v9.0/activitymimeattachments(81f6a467-6c6e-e811-a845-000d3a2a0765)
headers:
Content-type: Application/json
method: PATCH
{
"objecttypecode" : "email",
"objectid_activitypointer#odata.bind" : "/emails(08d23aaf-676e-e811-a845-000d3a2a0765)",
"body" : "bWlncmF0ZWQ="
}
The webapi returns 204: No content.
If I e.g. add the "subject" property, that will get updated, but the body remains the same.
When I do a post with the exact same body, it runs successful and the attachment is created.
Does anybody know why this happens and how to solve it?
There is an MSDN example using .Net.
Sample: Create, retrieve, update, and delete an email attachment.
It appears to also set the FileName, I suggest you attempt the same.
ActivityMimeAttachment _sampleAttachment = new ActivityMimeAttachment
{
ObjectId = new EntityReference(Email.EntityLogicalName, _emailId),
ObjectTypeCode = Email.EntityLogicalName,
Subject = String.Format("Sample Attachment {0}", i),
Body = System.Convert.ToBase64String(
new ASCIIEncoding().GetBytes("Example Attachment")),
FileName = String.Format("ExampleAttachment{0}.txt", i)
};

I am able to successfully attach PDF file with ServiceNow table record using GlideSysAttachment API and attachment.write() function in script, however whenever I download and try to open same, I get the error shown in below screenshot.
Code snippet
(function execute() {
try{
var rec = new GlideRecord('incident');
var attachment = new GlideSysAttachment();
var incidentSysID = incident.number;
rec.get(incidentSysID);
var fileName = 'Test_Incident.pdf';
var contentType = 'application/pdf'; // Also tried with contentType as 'text/pdf'
var content = pdf_content;
var agr = attachment.write(rec, fileName, contentType, content);<br>
gs.info('The PDF attachment sys_id is: ' + agr);
}catch(err){
gs.log('Got Error: ' + err);
gs.info(err);
}
})()
I also tried "AttachmentCreator" with ecc_queue within script but same error occurs. Below is code for it.
(function execute()
{var attCreator = new GlideRecord('ecc_queue');
attCreator.agent = "AttachmentCreator";
attCreator.topic = "AttachmentCreator";
attCreator.name = "Test.pdf" + ":" + "text/pdf";
//Also tried, "Test.pdf:application/pdf"
attCreator.source = "incident"+":"+ incident.number;
// Record Table name and sys_id of the particular record
var content = pdf_content; // pdf_content is any string variable
var stringUtil = new GlideStringUtil();
var base64String = stringUtil.base64Encode(content);
var isValid=GlideStringUtil.isBase64(base64String);
var base64String= gs.base64Encode(content);
gs.info("Is valid base64 format in ecc_queue ? "+ isValid);
attCreator.payload = base64String; //base64 content of the file
attCreator.insert();
})()
I am able to attach and view excel and word files with similar scripts without any issues. I have checked system properties for attachments but everything looks fine. I am able to view the PDF file uploaded from UI to particular table records however not the one I attach via REST API or scripts.
I have also tried sending encoded data as bytes, base64 or simple string but nothing seems to work. I don't get any errors and attachment id is returned each time on creation of attachment.
After modifying my code slightly for above functions w.r.t scoped application instead of global; I got some information from logs when I debug:
05:38:38.411 Security restricted: File type is not allowed or does not match the content for file Test.pdf
05:38:38.410 Security restricted: MIME type mismatch for file: Test.pdf. Expected type:application/pdf, Actual type: text/plain
05:38:38.394 App:XYZ App x_272539_xyz_ap: Is valid base64 format in ecc_queue ? true
First a comment: This line in your code is accidentally working -- make sure you understand that a task number is not the object sys_id
var incidentSysID = incident.number; // should be incident.sys_id
Next, it's unclear where the PDF content is coming from. IF your complete code is listed, I would expect the errors given as you have noted that pdf_content is "any string variable."
ServiceNow does have a the capability to create a PDF from an HTML argument.

I am trying to create a Zapier app to create a new invoice in Zoho.
Has the requirements: Content-Type: application: x-www-form-urlencoded and input JSON string should be passed using JSONString parameter
The following URI is working for me in REST console when I set the Content Type to "application/x-www-form-urlencoded" and method POST.
https://invoice.zoho.com/api/v3/invoices?authtoken=xxxxxx&organization_id=xxxxxx&JSONString={"customer_id":"xxxxxx","line_items":[{"item_id":"xxxxxx"}]}
However my problem is trying to implement this into Zapier. I think I need to use a function like below to convert the JSON into the right format, but I have no idea how to turn this into a query paramater called JSONString.
create_invoice_pre_write: function(bundle) {
var data = JSON.parse(bundle.request.data);
bundle.request.data = $.param(data);
bundle.request.headers['Content-Type'] = 'application/x-www-form-urlencoded';
return bundle.request;
}
Just need a point in the right direction. I'm not sure what to try next.
You can create an Invoice in Zoho Invoice through Zapier using the below snippet of code.
You can set the query params in bundle.request.params which you want to send it to ZI for the creation of Invoice.
create_invoice_pre_write: function(bundle)
{
var data = JSON.parse(bundle.request.data);
bundle.request.method = "POST",
bundle.request.url = "https://invoice.zoho.com/api/v3/invoices",
bundle.request.params.authtoken = {authtoken},
bundle.request.params.organization_id = {organization_id},
bundle.request.params.JSONString = data
bundle.request.headers= "'Content-Type':'application/x-www-form-urlencoded'";
return bundle.request;
}
This should be working for you. If you have any doubts do let me know.
I try to find solution to my problems but didn't find any where,hope that someone here can save me.
I write add-in in JavaScript on VS2015 that encrypte and decrypte body messages.
1. The first problem is with images that the receiver can't see .
(Talk about images that copy into the body by "insert picture inline" button)
In Compose mode we encrypte the message and then when we decrypte it's works good because the compose mode is a client side and he his recognize the local images .
In read mode when user want to decrypte the message and to see the images he couldn't see because the encrypte prevent outlook to convert the local image to data on the server .
In my code I take the body message like this ( compose mode )
item.body.getAsync(
item.body.getAsync(
"html",
{ asyncContext: "This is passed to the callback" },
function callback(resultbody) {
......Here we send the body for ENCRYPT.
}))
then , the user send the encrypte message by clicking 'send' regular.
In the read mode I just print it to my html to check if the decrypte is good :
(JSON.parse(xhr.responseText).Data.Content));
and then i get icon of picture ,but not success to show the real pic .
The src of the icon is going for place that not access for him ..
<img src="https://attachment.outlook.office.net/owa/*****/service.svc/s/GetFileAttachment?id=AAMkADUwMDE0YWM1LTYwODctNG ......
How can i take this tag of image and do something that the receiver can see the image ? I don't want that user will be need to upload image to body from my my add-in instead of the original outlook. I try to convert the image to base-64 string, but with what I have in the tag it not enough ,just with original picture and also it success to show in html but not in the body of message with SetAsync function..
2. The second problem is with attachments .
I upload files with dropzone plug-in (because outlook don't give access to take attachment and change him). So, after I upload files and encrypte him I make some new file with the response from server with File API of JS :
ar f = new File([""], "filename.txt", {type: "text/plain", lastModified: date}) . .. .
than I want to attach the file to mail, so the only method that do this is:
addFileAttachmentAsync(uri, attachmentName, optionsopt, callback opt)
then,I need to create a url for file for this method so I use this method:
var objectURL = URL.createObjectURL(f);
But now when I use the method addFileAttachmentAsync with objectURL it's write that there is a problem and its can't attach it , I think that the URL is incorrect .
Thanks all!!
For everyone who look any solution to this problems..
**In outlook web this solutions works good but in Outlook Desktop there is a problem of synchronize with server so there is a delay with saveAsync function without any solution to this right now , so it's work but need to wait a little bit.You could read more about it here.
First Question:
There is a problem in outlook add-in with when using getAsync and then setAsync functions . The problem occurs when there is some image inside the body . It's happen because when you take the body in Html format and then return the body with some different the image still not 'upload' and the src is being wrong .
I success to workaround this problem using Outlook rest API.
So the workaround is going like this:
Get the body message in type of Html by getAsync method. create div
element and set the return body message inside the div.
To get message id, you need to save your message as a draft with saveAsync function.
To make request to Outlook rest
API you need to get access token , so call to getCallbackTokenAsync function and save the access
token.
Make Http Request to outlook rest API to get all attachment exist in
the message.
Find the right ID of your image and replace the image src to the
base-64 of the image that you get from your request to outlook rest
API.
Finally , you could set your new body with SetAsync function .
Code:
item.body.getAsync(
Office.CoercionType.Html,
{ asyncContext: "This is passed to the callback" },
function callback(resultbody) {
var bodyDiv = document.createElement('div');
bodyDiv.innerHTML = content;
Office.context.mailbox.item.saveAsync(
function callback(result) {
var myNewItemSaved = result.value;
Office.context.mailbox.getCallbackTokenAsync({ isRest: true },
function (result) {
if (result.status === "succeeded") {
var accessToken = result.value;
var itemId = "";
if (Office.context.mailbox.diagnostics.hostName === 'OutlookIOS')
itemId = Office.context.mailbox.item.itemId;
else
itemId = Office.context.mailbox.convertToRestId(myNewItemSaved,
Office.MailboxEnums.RestVersion.v2_0);
var xhr3 = new XMLHttpRequest();
xhr3.open("GET", "https://outlook.office.com/api/v2.0/me/messages/" + itemId + "/attachments", true);
xhr3.setRequestHeader("Content-type", "application/json");
xhr3.setRequestHeader("Access-Control-Allow-Origin", "*");
xhr3.setRequestHeader("Authorization", "Bearer " + accessToken);
xhr3.send();
xhr3.onreadystatechange = function () {
if (xhr3.readyState == 4) {
if (xhr3.status == 200) {
var allImages = JSON.parse(xhr3.response).value;
var isDesktop = false;
var imgSrcId = bodyDiv.getElementsByTagName('img')[0].getAttribute("src");
if (imgSrcId.indexOf("cid") != -1) //Outlook Desktop
isDesktop = true;
for (var i = 0; i < allImages.length; i++) {
if (bodyDiv.getElementsByTagName('img')[i].getAttribute("src").indexOf("base64")!=-1)
continue;
if (isDesktop)
imgSrcId = bodyDiv.getElementsByTagName('img')[i].getAttribute("src");
else
imgSrcId = bodyDiv.getElementsByTagName('img'[i].getAttribute("originalsrc");
imgSrcId = imgSrcId.substr(4, imgSrcId.length);
var wantedImg;
for (var j = 0; j < allImages.length; j++) {
if ((allImages[j].ContentId).localeCompare(imgSrcId) != -1) {
wantedImg = allImages[j]; break;}
}
bodyDiv.getElementsByTagName('img')[i].src = 'data:' + wantedImg.ContentType + ';base64,' + wantedImg.ContentBytes;
}
}
setAsync......
}
}}}})})};
Second question
The problem with addFileAttachmentAsync that this is work only with files that is on external server, and it's not add a blob , local files.
So also here the solution is with Outlook rest API . The solution will attach our file to the message but we can't see this-no preview of the attachment in message , but when we send it this will attach to message , and we could see in our message that the attachment is there.
The solution is really similar to the one of the image in body - Save the message as a draft , get access token and this time the Http Request will be 'POST' request to our message id to attach our file to the current message.
Code to the request to add attachment to message ( all the way until here is the same like question 1):
var attachment ={
"#odata.type": "#Microsoft.OutlookServices.FileAttachment",
"Name": "smile.png",
"ContentBytes": "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"
}
var xhr4 = new XMLHttpRequest();
xhr4.open("POST", "https://outlook.office.com/api/v2.0/me/messages/" + itemId + "/attachments", true);
xhr4.setRequestHeader("Content-type", "application/json");
xhr4.setRequestHeader("Access-Control-Allow-Origin", "*");
xhr4.setRequestHeader("Authorization", "Bearer " + accessToken);
xhr4.send(JSON.stringify(attachment));
xhr4.onreadystatechange = function () {
if (xhr4.readyState == 4) {
if (xhr4.status == 200)
console.log("ok");
else
console.log(xhr4.response);
}};
Hope it's will help someone , good luck !
I am working on New web application which is Using Web API as Business Layer and Knock out Js as client side frame work to binding. I have a requirement like Pass the certain search criteria to Web API Controller and get the Data from DB and Create and Send the Excel/MS-Word file on the fly as a downloadable content.
I am new to both the Web API and Knock out, I am searching on the Net and get partial solution and I am looking here to get more optimal solution for this use case.
Below is my code:
Client:
function GetExcelFile() {
var $downloadForm = $("<form method='POST'>")
.attr("action", baseUrl + "api/FileHandler/GetExcelFileTest")
.attr("target", "_blank")
$("body").append($downloadForm);
$downloadForm.submit();
$downloadForm.remove();
}
On Button Click having this code snippet to create a form on the fly and Get response from Web API.
Web API Code:
[HttpPost]
public HttpResponseMessage GetExcelFileTest()
{
var response = new HttpResponseMessage();
//Create the file in Web App Physical Folder
string fileName = Guid.NewGuid().ToString() + ".xls";
string filePath = HttpContext.Current.Server.MapPath(String.Format("~/FileDownload/{0}", fileName));
StringBuilder fileContent = new StringBuilder();
//Get Data here
DataTable dt = GetData();
if (dt != null)
{
string str = string.Empty;
foreach (DataColumn dtcol in dt.Columns)
{
fileContent.Append(str + dtcol.ColumnName);
str = "\t";
}
fileContent.Append("\n");
foreach (DataRow dr in dt.Rows)
{
str = "";
for (int j = 0; j < dt.Columns.Count; j++)
{
fileContent.Append(str + Convert.ToString(dr[j]));
str = "\t";
}
fileContent.Append("\n");
}
}
// write the data into Excel file
using (StreamWriter sw = new StreamWriter(fileName.ToString(), false))
{
sw.Write(fileContent.ToString());
}
IFileProvider FileProvider = new FileProvider();
//Get the File Stream
FileStream fileStream = FileProvider.Open(filePath);
//Set response
response.Content = new StreamContent(fileStream);
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");
response.Content.Headers.ContentDisposition.FileName = fileName;
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/ms-excel");
response.Content.Headers.ContentLength = fileStream.Length;
//Delete the file
//if(File.Exists(filePath))
//{
// File.Delete(filePath);
//}
return response;
}
Using this code I am able to download an Excel File. Still I have some more open questions to make this code optimal.
Q1) I need to Pass view model(Search Criteria) to API Controller Using the dynamically create form ? (OR) Any better ways to get Excel file from Web API.
Q2) I am sure it's not a good way to create Excel file in Physical folder and Get FileStream and send as a respone. How to do on the fly ? OR any other optimal ways.
Please suggest me to do better ways.. Thanks
Q1) You can quite easily pass the view-model, but it's also similarly easy to pull that information from the posted form.
Passing the view-model
If you want to pass the view-model to a WebAPI method then remember that said method must take as a parameter an object with the same properties. So if the object that you wish to post back always has the same properties then it's trivial to build a server-side class with the same properties and receive an instance of that class.
To post back this client-side object you can do something like this (uses jQuery, which I see you're already using):
$.ajax({
contentType: "application/json",
data: my-view-model.toJSON(),
type: "POST",
url: baseUrl + "api/FileHandler/GetExcelFileTest" });
I haven't attached any success or error handlers here because the JavaScript isn't concerned with the return, but you might wish to add some handlers in case an exception is thrown in your WebAPI method. I recommend doing that by adding the following to the above $.ajax() call:
statusCode: {
500: function(jqXhr, textStatus, errorThrown) {
},
[other HTTP error codes]
}
[Read the documentation for the $.ajax() call here.]
One additional tip here: when you call my-view-model.toJSON() (or self.toJSON(), if called from within your view-model) Knockout will first of all determine if your view-model contains a toJSON() method. If so, it will use this method; if not then it will call the browser's implementation of this function. However, the browser's implementation of this function will serialise everything, which can be particularly length if you have, for example, long select lists in your view-model. Therefore, if you wish only to send back a subset of the view-model's properties then define your own toJSON function on your view-model like so:
var toJSON = function() {
return {
Property1: ...,
Property2: ...
};
}
[Read more about converting a view-model to JSON here.]
Posting the form as-is
If you don't wish to expend the effort to do the view-model wiring then you can just post the form exactly like you have in your question. You can then retrieve the values from the form by using
Request.Form["my-field"];
Q2)
You're probably right in pointing out that it's not wise to create the Excel file in the physical folder. However, as far as I'm aware (interested if someone says otherwise) you'll have to use a 3rd-party library for this. Microsoft do offer an Office automation library but I have a suspicion that you also need Office to be installed at the same location.
Creating Excel spreadsheets dynamically is something I've done several times but for the actual creation I use Aspose.Cells, which requires a license. Although I do create a physical version and then delete it, I believe Aspose.Cells may allow you to create it as a stream. But take a look around, there are certainly other libraries which offer Excel automation.
Returning the File from the Server
Calling $.ajax({...}) alone won't allow you to present the user with a "Save as..." dialog. What I do in this situation - and this won't work if you wish to store the generated file only in memory (FileStream, for example) and not on the file system - is to respond to the $.ajax({...}) call with a filename for the generated file.
The next step is to direct the user towards that filename.
So I have something like this in my JavaScript:
$.ajax({
dataType: "json",
type: "GET", // you'll probably want POST in your case
url: ...,
success: function(response) {
if (response && response.Uri && response.Uri.length) {
window.location.href = [root URL] + response.Uri;
}
}
});
But don't be alarmed by this redirect. That window.location.href points directly to a folder on the server, no controller needed. Because the browser then receives a file it presents the "Save as..." dialog while remaining on the same webpage.
I've a JSP app. It uploads a file, but to do so the user has to authenticate using a name and a password. So my JSP file starts with:
//0.2.- We get the password
String password = (String) request.getParameter("pass"); // -> This returns NULL
//0.3.- We get the "uvus"
String uvus = (String) request.getParameter("uvus"); //-> This also returns NULL
//More code
So I'm trying to know why am I getting null from those variables.
I went to the form I was uploading, and look for the data that was being sent. Using Firefox Debug Tools, I saw:
So in fact, it was being sent.
As additional info, I'm building the request like this:
var pUvus = document.getElementById("uvus").value;
var pPassword = document.getElementById("pass").value;
var file = document.getElementById("userFile");
var formData = new FormData();
formData.append("upload", file.files[0]);
formData.append("uvus", pUvus);
formData.append("pass", pPassword);
xmlhttp.open("POST","uploadFile.jsp",true);
xmlhttp.send(formData);
At last, I would like to say that I can get vars from application object in the same JSP with no errors, and have received in another pair of JSP files vars at request object without more problems, so I think my fault should be in the way I'm building the request in Ajax, but I've no more clue about that...
Anyone can guide me?
Thanks for your help
Update: #rickz asked for how do I get the file and parse the request (what is done after my problem, trying to get the objects from the request scope):
List items;
items = servlet_up.parseRequest(request);
for(int i=0;i<items.size();i++)
{
FileItem item = (FileItem) items.get(i);
if (! item.isFormField())
{
request.getParameter() won't work for a multipart/form-data request.
If you are using org.apache.commons.fileupload then you should be using something like
if(item.isFormField()){
name = item.getFieldName();
...
}
