不多说了直接上代码

public void ProcessRequest(HttpContext context)        {            context.Response.ContentType = "text/plain";            string uriString = "http://127.0.0.1/tools/Handler1.ashx";            WebClient myWebClient = new WebClient();            NameValueCollection myNameValueCollection = new NameValueCollection();            myNameValueCollection.Add("Name", "Tom");            myNameValueCollection.Add("Address", uriString);            myNameValueCollection.Add("Age",  "12");                        //虽然是异步调用 但是还会阻止当前的响应，所以从效果上看，还是会阻塞，这不是我想要的方式            //应该使用后台线程 去做这样的事情            //这个和控制台展示的效果不一样            myWebClient.UploadValuesCompleted += myWebClient_UploadValuesCompleted;            myWebClient.UploadValuesAsync(new Uri(uriString), null, myNameValueCollection, context);            //同步POST            //byte[] responseArray = myWebClient.UploadValues(uriString, myNameValueCollection);            //Decode and display the response.            //Response.Write(Encoding.ASCII.GetString(responseArray));             //context.Response.Write("Hello World");        }        void myWebClient_UploadValuesCompleted(object sender, UploadValuesCompletedEventArgs e)        {            Octopus.Common.CommonHelper.TraceLog(Encoding.ASCII.GetString(e.Result));        }        //接收        context.Response.ContentType = "text/plain";        System.Threading.Thread.Sleep(3000);        context.Response.Write("Hello World," + context.Request.Form["Name"] + ","                + context.Request.Form["Age"] + "," + context.Request.Form["Address"]);
