使用jQuery 1.8.3和1.9.1的CORS

Question

I am trying to make a PATCH/POST using CORS. The code below works on jQuery 1.9.1 but not works on 1.8.3.

var settingsB = {
          "async": false,
          "crossDomain": true,
          "url": "https://wmmr85ap13.execute-api.us-west-2.amazonaws.com/dev/customer/" + m,
          "method": "PATCH",
          "headers": {
            "content-type": "application/json"
          },
          "data": JSON.stringify({isFirstLogin: "false"})
        }

        $.ajax(settingsB).done(function (response) {

            console.log(response);
        });

On the jquery 1.8.1 I am getting:

XMLHttpRequest cannot load https://wmmr85ap13.execute-api.us-west-2.amazonaws.com/dev/customer/jvthales@gmail.com ?{%27isFirstLogin%27:%20false%20}. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://emporiodacerveja.vtexcommercestable.com.br ' is therefore not allowed access. The response had HTTP status code 400.

I imagine that the CORS is well configured on the server because the jQuery 1.9.1 works!

Is there any diffence doing post/patch using 1.9.1 vs 1.8.3 version?

EDITED: See below the difference between 1.9.1 vs 1.8.3 calls:

Answer 1

Need to set type and xhrFields

$.ajax({
   type : "PATCH",  //replaced my method in 1.9
   url: cross_domain_url,
   xhrFields: {
      withCredentials: true
   }
});

Answer 2

The method parameter was added in jQuery 1.9.0.

method
(default: 'GET')
Type: String The HTTP method to use for the request (eg "POST", "GET", "PUT"). (version added: 1.9.0)
