How to set headers in ajax call with jquery

Question

I need to call an Office 365 Rest API from my own application.

When I copy and paste the url on the same browser session, I can see some XML.

If I paste that URL into an incognito window I get this error:

The custom error module does not recognize this error.

I am trying to make an API call to get that response from my application, when checking with developer tools, how they call the service I can see this:

As you can see the API call has some request headers.

Google chrome has the functionality to copy that as a CURL request.

And this works for me:

curl "https://portal.office.com/api/myapps/GetAllApps" -H "AjaxSessionKey: wEAjKvw1WCmLD27I2TGqAuga25rq5HdKrdEOCOTXhfX4k6H3U/AQru+hPWfWSMX0hhQ++OFkm/FvKN+Z1moC1Q=="

But I always get this error:

What am I missing in this code, to be able to call the service just as CURL and return me the response I need?

Answer 1

Answering your title question is just use the headers settings for $.ajax. For instance:

$.ajax({
    url: 'https://portal.office.com/api/myapps/GetAllApps',
    type: 'GET',
    headers: {
        'Accept': 'application/json',
        'Accept-Encoding': 'gzip, deflate, sdch, br',...
}});

But I don't think that the error is caused because of missing headers. You should explain better the error, if is related with same-origin policy you should take a look on these links Working With and Around the Same-Origin Policy and Cross-Domain requests in Javascript).

Answer 2

I think you need to provide further information about this error but my first guess would be that the host has No 'Access-Control-Allow-Origin' enabled, and that's why you can do it from console.

You can try running chrome with --insecure or just install the allow-control-origin plugin

Answer 3

Can you try with by adding dataType: 'jsonp', crossDomain: true,
