Unable to view PDF attached with ServiceNow table records - servicenow

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.

Insert Image into a Google Sheet with Apps Script using base64 encoded data

Given some base64 encoded data for a png file, as in the example below from the image tag.
<img src="data:image/png;base64,R0lGODlhDAAMAKIFAF5LAP/zxAAAANyuAP/gaP///wAAAAAAACH5BAEAAAUALAAAAAAMAAwAAAMlWLPcGjDKFYi9lxKBOaGcF35DhWHamZUW0K4mAbiwWtuf0uxFAgA7">
I need to create an image blob from the base64 encoded data for the insertImage() method.
sheetClass.insertImage(imageBlob, column, row)
Documentation:
Sheets Class - insertImage method
I've tried using the code below, but it throws the error:
Execution failed: Error retrieving image from URL or bad URL
The documentation states that the method needs a blob, not a URL, but it seems like it's expecting a link to an image file.
function insertImageFromBase64Src() {
var data = 'R0lGODlhDAAMAKIFAF5LAP/zxAAAANyuAP/gaP///wAAAAAAACH5BAEAAAUALAAAAAAMAAwAAAMlWLPcGjDKFYi9lxKBOaGcF35DhWHamZUW0K4mAbiwWtuf0uxFAgA7';
var imageBlob = Utilities.newBlob(Utilities.base64Decode(data), 'image/png').getBytes();
var ss = SpreadsheetApp.getActiveSpreadsheet();//This code is bound to a Sheet
var po = {
shName:'Update File',
column:1,
row:37
}
var sh = ss.getSheetByName(po.shName);
var image = sh.insertImage(imageBlob, po.column, po.row);//Insert an image and return the image
}
How about this modification?
Modification points:
insertImage can use the blob and URL which is the direct link of the image file.
In your script, imageBlob is an byte array which is "number[]". By this, I think that an error occurs.
Please add the name to the blob.
When the name is not given, an error occurs.
Modified script:
When your script is modified, it becomes as follows.
function insertImageFromBase64Src2() {
var data = 'R0lGODlhDAAMAKIFAF5LAP/zxAAAANyuAP/gaP///wAAAAAAACH5BAEAAAUALAAAAAAMAAwAAAMlWLPcGjDKFYi9lxKBOaGcF35DhWHamZUW0K4mAbiwWtuf0uxFAgA7';
var imageBlob = Utilities.newBlob(Utilities.base64Decode(data), 'image/png', 'sample'); // Modified
var ss = SpreadsheetApp.getActiveSpreadsheet(); //This code is bound to a Sheet
var po = {
shName:'Update File',
column:1,
row:37
}
var sh = ss.getSheetByName(po.shName);
var image = sh.insertImage(imageBlob, po.column, po.row);//Insert an image and return the image
}
In this modification, it supposes that data can be correctly decoded.
References:
insertImage(blobSource, column, row)
insertImage(url, column, row)
If this was not the direct solution of your issue, I apologize.

Dynamics CRM Attachment Data Import Using SDK

I am trying to import Attachments/Annotations to CRM Dynamics, I am doing this using the SDK.
I am not using the data import wizard.
I am not individually creating Annotation entities, instead I am using Data Import Feature programmatically.
I mostly leveraged the DataImport sample from the SDK sample code (SDK\SampleCode\CS\DataManagement\DataImport).
Import import = new Import()
{
ModeCode = new OptionSetValue((int)ImportModeCode.Create),
Name = "Data Import"
};
Guid importId = _serviceProxy.Create(import);
_serviceProxy.Create(
new ColumnMapping()
{
ImportMapId = new EntityReference(ImportMap.EntityLogicalName, importMapId),
ProcessCode = new OptionSetValue((int)ColumnMappingProcessCode.Process),
SourceEntityName = sourceEntityName,
SourceAttributeName = sourceAttributeName,
TargetEntityName = targetEntityName,
TargetAttributeName = targetAttributeName
});
I am getting an error "The reference to the attachment could not be found".
The documentation says the crm async service will find the physical file on disk and upload it, my question is where does the async service look for attachment files?
I tried to map documentbody field to the full path of the attachment on the desk, but that still didn't work.
The answer below was provided before the question edits clarifying the use of the import wizard instead of the SDK. The answer below is specific to using the SDK.
When you are attaching files to an Annotation (Note) record in CRM via the SDK, you do use the documentbody attribute (along with mimetype), but you have to first convert it base64.
Something like this:
var myFile = #"C:\Path\To\My\File.pdf";
// Do checks to make sure file exists...
// Convert to Base64.
var base64Data = Convert.ToBase64String(System.IO.File.ReadAllBytes(myFile));
var newNote = new Entity("annotation");
// Set subject, regarding object, etc.
// Add the data required for a file attachment.
newNote.Attributes.Add("documentbody", base64Data);
newNote.Attributes.Add("mimetype", "text/plain"); // This mime type seems to work for all file types.
orgService.Create(newNote);
I found the solution in an obscure blog post, I think the documentation is misleading or unclear, the way this whole thing works, makes having the files available on the server disk for the async to process, odd.
To follow the same principle, all contents should be sent like the csv file itself while being linked to the same import.
To solve this we need create individual special Internal ImportFile for each physical attachment, and link it to the import that has the attachments record details.
As you see below with linking the attachments ImportFile using the ImportId and then setting the two properties (ProcessCode and FileTypeCode), it all worked in the end.
Suffice to say using this method is much more efficient and quicker than individually creating Annotation records.
foreach (var line in File.ReadLines(csvFilesPath + "Attachment.csv").Skip(1))
{
var fileName = line.Split(',')[0].Replace("\"", null);
using (FileStream stream = File.OpenRead(attachmentsPath + fileName))
{
byte[] byteData = new byte[stream.Length];
stream.Read(byteData, 0, byteData.Length);
stream.Close();
string encodedAttachmentData = System.Convert.ToBase64String(byteData);
ImportFile importFileAttachment = new ImportFile()
{
Content = encodedAttachmentData,
Name = fileName,
ImportMapId = new EntityReference(ImportMap.EntityLogicalName, importMapId),
UseSystemMap = true,
ImportId = new EntityReference(Import.EntityLogicalName, importId),
ProcessCode = new OptionSetValue((int)ImportFileProcessCode.Internal),
FileTypeCode = new OptionSetValue((int)ImportFileFileTypeCode.Attachment),
RecordsOwnerId = currentUserRef
};
_serviceProxy.Create(importFileAttachment);
}
idx++;
}

Receiving null parameters from request in JSP file when are being sent

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();
...
}

Is there any way of suppressing ‘Do you want to save changes to xxx.pdf before closing’ dialog using ABCpdf

We are reading the adobe form template using ABCpdf , populating form fields with values retrieved from database and amending them into a single PDF document and sending the document back as File stream in the HTTP response to the users in a ASP.net MVC App.
This approach is working fine and PDF documents are getting generated successfully. But when the user choose to open the generated PDF file and try to close it, they are being prompted ‘Do you want to save changes to xxx.pdf before closing’ dialog from Adobe Acrobat. Is there any way of suppressing this message using ABC pdf?.
Following is the code we are using to generate the PDF.
public byte[] GeneratePDF(Employee employee, String TemplatePath)
{
string[] FieldNames;
Doc theDoc;
MemoryStream MSgeneratedPDFFile = new MemoryStream();
//Get the PDF Template and read all the form fields inside the template
theDoc = new Doc();
theDoc.Read(HttpContext.Current.Server.MapPath(TemplatePath));
FieldNames = theDoc.Form.GetFieldNames();
//Navigate through each Form field and populate employee details
foreach (string FieldName in FieldNames)
{
Field theField = theDoc.Form[FieldName];
switch (FieldName)
{
case "Your_First_Name":
theField.Value = employee.FirstName;
break;
default:
theField.Value = theField.Name;
break;
}
//Remove Form Fields and replace them with text
theField.Focus();
theDoc.Color.String = "240 240 255";
theDoc.FillRect();
theDoc.Rect.Height = 12;
theDoc.Color.String = "220 0 0";
theDoc.AddText(theField.Value);
theDoc.Delete(theField.ID);
}
return theDoc.GetData();
}
Today I ran into this problem too, but with a PDF with no form fields. I ran #CharlieNoTomatoes code and confirmed the FieldNames collection was definitely empty.
I stepped through the various stages of my code and found that if I saved the PDF to the file system and opened from there it was fine. Which narrowed it down to the code that took the abcpdf data stream and sent it directly to the user (I normally don't bother actually saving to disk). Found this in the WebSuperGoo docs and it suggested my server might be sending some extra rubbish in the Response causing the file to be corrupted.
Adding Response.End(); did the trick for me. The resulting PDF files no longer displayed the message.
byte[] theData = _thisPdf.Doc.GetData();
var curr = HttpContext.Current;
curr.Response.Clear();
curr.Response.ContentType = "application/pdf";
curr.Response.AddHeader("Content-Disposition", "attachment; filename=blah.pdf");
curr.Response.Charset = "UTF-8";
curr.Response.AddHeader("content-length", theData.Length.ToString());
curr.Response.BinaryWrite(theData);
curr.Response.End();
I ran into this problem, as well. I found a hint about "appearance streams" here:
The PDF contains form fields and the NeedAppearances entry in the interactive form dictionary is set to true. This means that the conforming PDF reader will generate an appearance stream where necessary for form fields in the PDF and as a result the Save button is enabled. If the NeedAppearances entry is set to false then the conforming PDF reader should not generate any new appearance streams. More information about appearance streams in PDF files and how to control them with Debenu Quick PDF Library.
So, I looked for "appearance" things in the websupergoo doc and was able to set some form properties and call a field method to get rid of the "Save changes" message. In the code sample above, it would look like this:
Edit: After exchanging emails with fast-and-helpful WebSuperGoo support about the same message after creating a PDF with AddImageHtml that WASN'T fixed by just setting the form NeedAppearances flag, I added the lines about Catalog and Atom to remove the core document NeedAppearances flag that gets set during AddImageHtml.
public byte[] GeneratePDF(Employee employee, String TemplatePath)
{
string[] FieldNames;
Doc theDoc;
MemoryStream MSgeneratedPDFFile = new MemoryStream();
//Get the PDF Template and read all the form fields inside the template
theDoc = new Doc();
theDoc.Read(HttpContext.Current.Server.MapPath(TemplatePath));
FieldNames = theDoc.Form.GetFieldNames();
//Tell PDF viewer to not create its own appearances
theDoc.Form.NeedAppearances = false;
//Generate appearances when needed
theDoc.Form.GenerateAppearances = true;
//Navigate through each Form field and populate employee details
foreach (string FieldName in FieldNames)
{
Field theField = theDoc.Form[FieldName];
switch (FieldName)
{
case "Your_First_Name":
theField.Value = employee.FirstName;
break;
default:
theField.Value = theField.Name;
break;
}
//Update the appearance for the field
theField.UpdateAppearance();
//Remove Form Fields and replace them with text
theField.Focus();
theDoc.Color.String = "240 240 255";
theDoc.FillRect();
theDoc.Rect.Height = 12;
theDoc.Color.String = "220 0 0";
theDoc.AddText(theField.Value);
theDoc.Delete(theField.ID);
}
Catalog cat = theDoc.ObjectSoup.Catalog;
Atom.RemoveItem(cat.Resolve(Atom.GetItem(cat.Atom, "AcroForm")), "NeedAppearances");
return theDoc.GetData();
}

html5 multiple upload along with ajax

I am trying to use the multiple upload attribute of HTML5 to upload files.
I know it wouldn't work with IE and fall back to single file upload.
also I found some invalid html tag like min max allows opera to do the same.
I am trying to do the following:
The browse button be capable of selecting multiple files.
But the ajax should send files one by one.
My scenario is something like this:
the user selects 5 files and starts the upload . Now the ajax should firstfile send the first file, then second, and so on.
The server side script does something with the file and returns some data.
now as soon as one file upload is completed it must render that part of the result.
So as the user selects images and starts uploading the results come out as soon as each file is uploaded (and not after all the files are uploaded).
I tried something like this :
function handleFiles(files)
{ alert(files.length); //properly returns the number of files selected
for (var i = 0; i < files.length; i++) {
new FileUpload(files[i])
}
}
function FileUpload(file) {
var reader = new FileReader();
var xhr = new XMLHttpRequest();
this.xhr = xhr;
xhr.open("POST", "portfolio/add_media");
reader.onload = function(evt) {
xhr.sendAsBinary(evt.target.result);
};
reader.readAsBinaryString(file);
}
after reading the tutorial at mozilla but I end up with missing params.
. so can some one suggest me a clean solution to this
Some more details :
When I pass a single file ( with no multiple attribute ) my server recieves :
"image"=>[# < ActionDispatch::Http::UploadedFile:0x10d55be8
#tempfile=#< File:C:/Users/Gaurav/AppData/Local/Temp/RackMultipart20110701-1916-2ly4k2-0>,
#headers="Content-Disposition:
form-data; name=\"picture[image][]\";
filename=\"Desert.jpg\"\r\nContent-Type:
image/jpeg\r\n",
#content_type="image/jpeg",
#original_filename="Desert.jpg">]}}
But when I use multiple attribute and send using xhr I am able to get only one file param. How do I get the rest of the params ? esp the action dispatch thingy
You are simply sending the file data to the server, without encoding it in any way. For the server to know how to process it you need to encode your data properly (multipart/form-data encoding). Easiest way is using a FormData object: https://developer.mozilla.org/En/Using_XMLHttpRequest#Sending_files_using_a_FormData_object. Only that instead of data.append("CustomField", "This is some extra data") you would write data.append("file1", event.target.result).
