C#后台跨域请求

通过C#后台发送请求来实现跨域访问(后台消耗会增大)，源码如下：

string URL = "www.xxx.com"; public void sendPost(string urlArgs,HttpContext context) { //context.Request["args"] System.Net.WebClient wCient = new System.Net.WebClient(); wCient.Headers.Add("Content-Type", "application/x-www-form-urlencoded"); byte[] postData = System.Text.Encoding.ASCII.GetBytes("id=" + urlArgs); byte[] responseData = wCient.UploadData(URL, "POST", postData); string returnStr = System.Text.Encoding.UTF8.GetString(responseData);//返回接受的数据 context.Response.ContentType = "text/plain"; context.Response.Write(returnStr); }
