error 500 in ajax call when call to the server, but in localhost works

I have a js when i do a ajax call to one server. When i call to this service using localhost, works. But when i call to this service using the server where i upload it, its ERROR 500. The call return a json.
$.ajax({
url: "https://www.example.com/example",
dataType: "json",
data: {
'data': xml,
'message': message,
'customer_id': customer_id,
'subscr_id': subscr_id
},
type: 'POST',
success: function (devol) {
},
error: function (xhr, ajaxOptions, thrownError) {
alert("no ha entrado");
}
});

Try to update your code below:
var model = {
'data': xml,
'message': message,
'customer_id': customer_id,
'subscr_id': subscr_id
};
$.ajax({
url: "https://www.example.com/example",
type: 'POST',
dataType: 'json',
data: JSON.stringify(model),
//headers: { 'authorization': `Bearer ${token}` },
async: false,
processData: false,
contentType: "application/json",
error: function (err) {
},
success: function (data) {
}
});

It might be because of CORS (Cross-Origin Resource Sharing)... Usually, you cannot make calls to other domains from the browser unless the other domain you are making calls allows CORS to all sites or specific sites.

How to get each data before ajaxSend in JSON not after complete/success

I want all the ajax params before sending an ajax request in JSON format and I need to encrypt each value in JSON and again pass to the ajax request.
I get data in URI format as see in below code, not in JSON. How can I get that?
Around 200 Ajax in this format:
$.ajax({
type: "POST",
url: site_url + "user/user/login_action",
data: login_parms,
success: function (data) {
},
error: function (xhr, textStatus, errorThrown) {
}
});
Before Ajax Call:
$(document).ajaxSend(function(event, jqxhr, settings) {
console.log("settings :",settings.data);
});
Console log:
settings : vEmail=disha.c1%40grr.la&vPassword=123456789
Also if in AJAX use formData then how we can get each value of form data?

If you want to send a AJAX JSON CALL you must to use:
$.ajax({
type: "POST",
url: site_url + "user/user/login_action",
dataType: "json",
async: false,
contentType: "application/json",
data: JSON.stringify(login_parms),
success: function (data) {
},
error: function (xhr, textStatus, errorThrown) {
}
});
if you want to modify the param:
$.ajax({
beforeSend: function(xhr){
this.data
}
});

ajax post method treated as get by restclient

I got an url let’s say abc its type is post. if I try to call it as $.ajax method post it is showing method not allowed 405 error. it I sent by method get it is working fine but the business is not done how to solve the issue?
js code:
$.ajax({
type: "POST",
url: url,
data: data,
beforeSend: function (request){
request.setRequestHeader("X-CSRF-TOKEN", token)
},
success: function(res){
console.log(res)
},
error: function(){
JSON.parse(this.error.arguments[0].responseText).error.message.value
},
dataType: "json"
});

You should use 'method' instead of 'type'. Try this:
$.ajax({
method: "POST",
url: url,
data: data,
beforeSend: function (request){
request.setRequestHeader("X-CSRF-TOKEN", token)
},
success: function(res){
console.log(res)
},
error: function(){
JSON.parse(this.error.arguments[0].responseText).error.message.value
},
dataType: "json"
});
Or you can use the jQuery.post method.

405 Method Not Allowed
The method specified in the Request-Line is not allowed for the resource identified by the Request-URI. The response MUST include an Allow header containing a list of valid methods for the requested resource. 405 Method Not Allowed

Issue sending AJAX request to another domain

I am trying to use this API: https://zipcodedistanceapi.redline13.com/API
But when I make the AJAX call, I'm getting this error:
XMLHttpRequest cannot load
https://zipcodedistanceapi.redline13.com/rest//radius.json/30341/10/mile.
No 'Access-Control-Allow-Origin' header is present on the requested
resource.
Here is the request:
$.ajax({
type: "GET",
url: 'https://zipcodedistanceapi.redline13.com/rest/<api key goes here...>/radius.json/30341/10/mile',
dataType: "json",
success: function(zipback) {
}
});
I know it has something to do with making the request from a different domain, but I don't not how to resolve the issue.

$.ajax({
type: "GET",
url: 'https://zipcodedistanceapi.redline13.com/rest/<api key goes here...>/radius.json/30341/10/mile',
dataType: "json",
jsonpCallback:'somename',
success: function(zipback) {
}
});

Jquery jsonp response error - Callback was not called

I'm trying to get some information from a different domain, the domain allows only jsonp call - others get rejected. How can I get the content instead of execution? Because I get an error in response. I don't need to execute it, I just need it in my script. In any format (the response is json but js doesn't understand it).
I can't affect on that domain so it's impossible to change something on that side.
Here's my code:
$.ajax({
url: url + '?callback=?',
crossDomain: true,
type: "POST",
data: {key: key},
contentType: "application/json; charset=utf-8;",
async: false,
dataType: 'jsonp',
jsonp: 'callback',
jsonpCallback: 'jsonpCallback',
error: function(xhr, status, error) {
console.log(status + '; ' + error);
}
});
window.jsonpCallback = function(response) {
console.log('callback success');
};

There are a few issues with your $.ajax call.
$.ajax({
url: url + '?callback=?',
// this is not needed for JSONP. What this does, is force a local
// AJAX call to accessed as if it were cross domain
crossDomain: true,
// JSONP can only be GET
type: "POST",
data: {key: key},
// contentType is for the request body, it is incorrect here
contentType: "application/json; charset=utf-8;",
// This does not work with JSONP, nor should you be using it anyway.
// It will lock up the browser
async: false,
dataType: 'jsonp',
// This changes the parameter that jQuery will add to the URL
jsonp: 'callback',
// This overrides the callback value that jQuery will add to the URL
// useful to help with caching
// or if the URL has a hard-coded callback (you need to set jsonp: false)
jsonpCallback: 'jsonpCallback',
error: function(xhr, status, error) {
console.log(status + '; ' + error);
}
});
You should be calling your url like this:
$.ajax({
url: url,
data: {key: key},
dataType: 'jsonp',
success: function(response) {
console.log('callback success');
},
error: function(xhr, status, error) {
console.log(status + '; ' + error);
}
});
JSONP is not JSON. JSONP is actually just adding a script tag to your <head>. The response needs to be a JavaScript file containing a function call with the JSON data as a parameter.
JSONP is something the server needs to support. If the server doesn't respond correctly, you can't use JSONP.
Please read the docs: http://api.jquery.com/jquery.ajax/

var url = "https://status.github.com/api/status.json?callback=apiStatus";
$.ajax({
url: url,
dataType: 'jsonp',
jsonpCallback: 'apiStatus',
success: function (response) {
console.log('callback success: ', response);
},
error: function (xhr, status, error) {
console.log(status + '; ' + error);
}
});
Try this code.
Also try calling this url directly in ur browser and see what it exactly returns, by this way You can understand better what actually happens :).

The jsonpCallback parameter is used for specifying the name of the function in the JSONP response, not the name of the function in your code. You can likely remove this; jQuery will handle this automatically on your behalf.
Instead, you're looking for the success parameter (to retrieve the response data). For example:
$.ajax({
url: url,
crossDomain: true,
type: "POST",
data: {key: key},
contentType: "application/json; charset=utf-8;",
async: false,
dataType: 'jsonp',
success: function(data){
console.log('callback success');
console.log(data);
}
error: function(xhr, status, error) {
console.log(status + '; ' + error);
}
});
You can also likely remove the other JSONP-releated parameters, which were set to jQuery defaults. See jQuery.ajax for more information.
