GetRequestStream 无法连接到服务器 目标计算机积极拒绝 127.0.0.1 1080

一个下午由于对HttpWebRequest 用得很少原因，折腾了一个晚上

接入正题：在C# 后台使用HttpWebRequest post数据的时候，提示 无法连接到服务器 

最后通过googel  https://www.experts-exchange.com/questions/20936810/Error-Unable-to-connect-to-the-remote-server-when-using-GetResponse-or-EndGetResponse.html

 

 

 

具体原因 可参考 https://www.cnblogs.com/AllanDragoon/p/3323370.html

下面贴出我的代码

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.ContentType = "text/xml; charset=utf-8";
webRequest.Method = "POST";
webRequest.KeepAlive = false;

using (Stream requestStream = webRequest.GetRequestStream())
{
byte[] paramBytes = Encoding.UTF8.GetBytes(body.ToString());
requestStream.Write(paramBytes, 0, paramBytes.Length);
}

WebResponse webResponse = webRequest.GetResponse();
using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))
{
　　object reun = myStreamReader.ReadToEnd();
　　return reun;
}
