I would like to post an ajax call to update a list without updating the version. I was told I can make use of the ValidateUpdateListItem() function. However, when I try using it, I have the error: System.ArgumentNullException value cannot be null parameter name: formValues. Here is a code snippet.
url: "path/ValidateUpdateListItem()",
method: "POST",
contentType: "application/json;odata=verbose",
headers: {
"Accept": "application/json; odata=verbose",
"IF-MATCH": request.ETag,
"X-HTTP-Method": "MERGE",
"X-RequestDigest": $('#__REQUESTDIGEST').val()
},
data: JSON.stringify({
"formValues":[
{
'Field1': 'value1'
}
],
'bNewDocumentUpdate': true
}),

I'm trying to perform an AJAX post but I keep getting a null FromBody in my .NET controller. I think it has to do with how I'm formatting my AJAX post.
When I attempt to post with AJAX I get a null FromBody.
var data = {
Date: "2016-12-01",
BurnIdx: 23,
BurnStatIdx1: 3,
BurnStatIdx2: 3,
BurnStatIdx3: 3,
BurnSevIdx: 5,
WorkOrder: 32426,
Comment: "Hi"
};
$('#submit').on('click',function () {
$.ajax({
type: 'POST',
url: 'Home/BurnerMapUpdate',
dataType: 'json',
contentType: 'application/json',
data: data,
success: function (result) {
console.log('Data received');
console.log(result);
}
});
});
However, when I attempt a post in Postman it's successful.
Figured out my problem. Needed to use JSON.stringify on my data.
$('#submit').on('click',function () {
$.ajax({
type: 'POST',
url: 'Home/BurnerMapUpdate',
dataType: 'json',
contentType: 'application/json',
data: JSON.stringify(data),
success: function (result) {
console.log('Data received');
console.log(result);
}
});
Not only the JSON.stringify().
If your data don't match with csharp class data it doesn't receive anything.
Like if you define in the class a field with int type, and send it in the json like "1", it happens to receive the whole data as null
I know you are already figured out of this problem. But I faced with the same just right now. My mistake was I used BODY parameter instead DATA in ajax request.
My Invalid ajax:
function sendRequest(url, method, body, callbackOk, callbackFail) {
$.ajax({
url: url,
body: JSON.stringify(body),
method: method,
contentType: 'application/json; charset=utf-8',
success: callbackOk,
error: callbackFail
})
Valid:
function sendRequest(url, method, body, callbackOk, callbackFail) {
$.ajax({
url: url,
data: JSON.stringify(body),
method: method,
contentType: 'application/json; charset=utf-8',
success: callbackOk,
error: callbackFail
})
}
$.ajax({
type: "POST",
url: baseUrl + "query?v=21266702",
contentType: "application/json; charset=utf-8",
dataType: "json",
headers: {
"Authorization": "Bearer " + accessToken
},
data: JSON.stringify({ query: text, lang: "en", sessionId: reqIdToken }),
success: function(data) {
xyz
}else{
setResponseForIT(data,"");
}
},
error: function() {
setResponse("Internal Server Error");
}
});
You would assign this stuff to variables before sending the raw data.
You have the data right here :
query: text, lang: "en", sessionId: reqIdToken
you are basically building the JSON on the fly, just process these before by setting them as variables.
Update (for clarification) :
This is creating json for you based on the variables already set etc.
JSON.stringify({ query: text, lang: "en", sessionId: reqIdToken })
This means you have access to 'text' and 'reqIdToken' and hence don't need to look at the 'data' variable that contains the json. Just use reqIdToken if you want to know the sessionId. (e.g. if (reqIdToken == "999") alert();)
I'm working with learning some javascript to make a post to a little rest API I created with django rest. I have a post that works when I was working with jQuery but now I am reimplementing using Vue.js and am hitting a snag. When I do the below post request I get a 400 error and am not sure what I am missing. I would imagine something with my header is incorrect? Any advice would be welcome.
axios({
method: 'post',
url: '/api/matches/',
data: JSON.stringify(data),
headers: {
"X-CSRFToken": csrfToken,
"Content-Type": "application/json"
}
})
jQuery post for reference:
$.ajax({
type: "POST",
url: "/api/matches/",
data: JSON.stringify(final_data),
success: function() {},
error: function(err) {console.log(err)},
contentType: "application/json; charset=utf-8",
dataType: "json",
crossDomain:false,
beforeSend: function(xhr, settings) {
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
});
I have two verions of code I believe should do the same thing, but the first one works and other one doesn't (Post vars: agenti, week_, team_). I have searched for few examples of how to do it the other way and I am sure my example is similar.
What do I do wrong?
First:
$.post("index.html",
{
agenti: getItems(),
week_: week_array,
team_: team
},
function(data,status){
if (status = 'Success'){
alert('Aktuální řazení operátorů bylo úspěšně uloženo.');
} else {
alert('Aktuální řazení operátorů se nepodařilo uložit.\nKontaktujte prosím správce aplikace.');
}
Second:
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
url: "index.html",
data: JSON.stringify({agenti: getItems(), week_: week_array, team_: team}),
success: function (msg)
{
alert('Aktuální řazení operátorů bylo úspěšně uloženo.')
},
error: function (msg)
{
alert('Aktuální řazení operátorů se nepodařilo uložit.\nKontaktujte prosím správce aplikace.')
}
});
I want to do the second one because I need to specify content type and i couldn't figure how to do it in the first way.
Thanks you!
edit: I use IE; this code will be used only in IE.
so the first thing is that, no need to use JSON.stringify function, as the data accepts JSON objects, as well the string represented like a url (test1=1&test2=2...). So to use it like the following is ok.
data: {agenti: getItems(), week_: week_array, team_: team},
Also when you are using contentType: 'application/json' the GLOBAL $_POST variable is not being populated as it is being populated only for form-urlencoded data which is default value for contentType option, here you go with data from jQuery reference`
contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')
In order you like to use application/json, you can retrieve that information in PHP side using php input like this following. file_get_contents('php://input');
---Working Example---
Javascript:
$.ajax({
type: "POST",
// contentType: "application/json; charset=utf-8",
dataType: "json",
url: "http://localhost",
data: {agenti: 'test1', week_: 'test2', team_: 'test3'},
success: function(msg) {},
error: function(msg) {}
});
PHP:
// Retrieve the input
var_dump(file_get_contents('php://input'));
// Use $_POST var
echo json_encode($_POST);
I am having problem to mock one end point. Mockjax intercept the request when retrieving the params the from the URL. Nevertheless, when I add them into the URL or the data object, the request passes through.
I need to make two occurrences of this call pass. Otherwise, my integration tests are failing.
I am working with global calls. All other calls are working properly minus this one.
