2 解决办法

在APP用socket服务器返回头里面添加如下关键代码

                header="Content-Type: "+ JSON_TYPE + "; charset=utf-8 \r\n"+ "Connection: close\r\n"+ "Access-Control-Allow-Origin: " + Request.origin + "\r\n"+ "Access-Control-Allow-Headers: *\r\n"+ "Access-Control-Allow-Credentials: true\r\n"+ "Access-Control-Allow-Methods: GET, HEAD, POST, PUT, PATCH, DELETE, OPTIONS\r\n"+ "Access-Control-Max-Age: 86400\r\n"+"Content-length: "+ length +" \r\n\r\n";

1) Access-Control-Allow-Origin</
