C#.net 设置Access-Control-Allow-Origin来实现跨域

来自于：zslm_

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Methods" value="OPTIONS,POST,GET" />
        <add name="Access-Control-Allow-Headers" value="x-requested-with,content-type" />
        <add name="Access-Control-Allow-Origin" value="*" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>

或者在Action或Action过滤器里设置

Response.Headers.Add("Access-Control-Allow-Origin", "*");
Response.Headers.Add("Access-Control-Allow-Methods", "POST");
Response.Headers.Add("Access-Control-Allow-Headers", "x-requested-with,content-type");
