在有多个 IP (.NET) 时选择 HTTP 请求使用的 IP [英] Choosing which IP the HTTP request is using when having multiple IPs (.NET)

问题描述

我正在编写一个 .NET 程序，它将在具有多个 IP 地址的计算机上运行.该程序向给定的网址发出 HTTP 请求.我想选择我使用的 IP 地址(这样我就可以确定哪个 IP 地址会出现在其他服务器的日志中).

I am writing a .NET program which will run on a computer with several IP addresses. The program makes HTTP requests to given web addresses. I want to choose which IP address I use (so I can determine which IP address will appear on the log of the other server).

建议?

推荐答案

我相信您可以通过提供一个 BindIPEndPointDelegate 来强制本地端点，它提供要绑定到的 IP/端口.

I believe you can force the local endpoint by providing a BindIPEndPointDelegate which supplies the IP/port to bind to.

string sendingIp = "192.168.0.1";
int sendingPort = 5000;
Uri uri = new Uri("http://google.com");
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(uri);
ServicePoint sp = ServicePointManager.FindServicePoint(uri);
sp.BindIPEndPointDelegate =
    (servicePoint,remoteEp,retryCount) =>
         {
             return new IPEndPoint(IPAddress.Parse(sendingIp),sendingPort);
         };
var data = new StreamReader(wr.GetResponse().GetResponseStream()).ReadToEnd();

此代码未正确处理处置.

This code doesn't deal with disposal correctly.
