ASP. NET and jQuery to solve the problem of cross domain call

1. Use JSONp to call

For no detailed explanation, please refer to the jq document "jQuery 1.10. 3 Online Manual"

2. Server-side configuration

Modify the Web. config file

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true"></modules>
  <httpProtocol>
   <customHeaders>
    <add name="Access-Control-Allow-Origin" value="*"/>
    <add name="Access-Control-Allow-Headers" value="Content-Type"/>
    <add name="Access-Control-Allow-Methods" value="GET,POST,PUT,DELETE"/>
   </customHeaders>
  </httpProtocol>
</system.webServer>

The client call code is as follows

var param = {};
var msg = "dafdasfdsaf";
param["userName"] = "1";
param["passWord"] = "1";
param["code"] = "3323";
$.ajax({
  url: "http://www.ts-wms.com/UserAjax/Login?t=" + Math.random(),
  data: param,
  type: "post",
  async:false,
  success: function (result) {
    alert(result);
    msg = result;
  }
});
alert(msg+"ddddddddddFFFFFFFFFFFFFFFF");

After testing, the call is successful, and it can be used for mobile phone call.
