jQuery的AJAX返回状态code 0同时要求跨域 [英] jquery ajax returns status code 0 while requesting cross domain

问题描述

我试图让跨域请求，但服务器可以与任何反应

i am trying to make cross domain request but server can not response with

Access-Control-Allow-Origin: *

我想读的响应头。 当我试图读取状态code或待机状态则返回0。我的code为Ajax请求如下：

i am trying to read response header. when i am trying to read status code or ready state it returns 0. my code for ajax request is as follows.

$.ajax({
       url: "https://accounts.google.com/o/oauth2/auth",
       type: "POST",
        data:   {"response_type":"token","client_id":"6720XXXXXXX.apps.googleusercontent.com","redirect_uri":"http://localhost:51967/oauth2callback.aspx","scope":"https://www.googleapis.com/auth/calendar","state":"this is state information","approval_prompt":"auto"},            
                crossDomain: true
        }).always(function(jqxhr,testStatus,errorThrown)
        {
                alert(jqxhr.readyState);
                alert(jqxhr.status);
        });

在此先感谢
