我有一个相当大的代理服务器列表,以及它们各自的端口。我该如何检查它们是否可用?

工作了吗?好的,你必须使用它们来查看它们是否工作。
如果您想查看它们是否在线,我猜ping
是第一步。
在.NET中有一个Ping类。
using System.Net.NetworkInformation;
private static bool CanPing(string address)
{
Ping ping = new Ping();
try
{
PingReply reply = ping.Send(address, 2000);
if (reply == null) return false;
return (reply.Status == IPStatus.Success);
}
catch (PingException e)
{
return false;
}
}
我喜欢通过代理进行WhatIsMyIP检查作为测试。
using RestSharp;
public static void TestProxies() {
var lowp = new List<WebProxy> { new WebProxy("1.2.3.4", 8080), new WebProxy("5.6.7.8", 80) };
Parallel.ForEach(lowp, wp => {
var success = false;
var errorMsg = "";
var sw = new Stopwatch();
try {
sw.Start();
var response = new RestClient {
//this site is no longer up
BaseUrl = "https://webapi.theproxisright.com/",
Proxy = wp
}.Execute(new RestRequest {
Resource = "api/ip",
Method = Method.GET,
Timeout = 10000,
RequestFormat = DataFormat.Json
});
if (response.ErrorException != null) {
throw response.ErrorException;
}
success = (response.Content == wp.Address.Host);
} catch (Exception ex) {
errorMsg = ex.Message;
} finally {
sw.Stop();
Console.WriteLine("Success:" + success.ToString() + "|Connection Time:" + sw.Elapsed.TotalSeconds + "|ErrorMsg" + errorMsg);
}
});
}
然而,我建议明确地测试不同类型(即http、https、socks4、socks5)。以上仅检查https。在为https://theproxisright.com/#proxyChecker构建ProxyChecker时,我从上面的代码开始,然后逐渐扩展到其他功能/类型。
试试这个:
public static bool SoketConnect(string host, int port)
{
var is_success = false;
try
{
var connsock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
connsock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 200);
System.Threading.Thread.Sleep(500);
var hip = IPAddress.Parse(host);
var ipep = new IPEndPoint(hip, port);
connsock.Connect(ipep);
if (connsock.Connected)
{
is_success = true;
}
connsock.Close();
}
catch (Exception)
{
is_success = false;
}
return is_success;
}
string strIP = "10.0.0.0";
int intPort = 12345;
public static bool PingHost(string strIP , int intPort )
{
bool blProxy= false;
try
{
TcpClient client = new TcpClient(strIP ,intPort );
blProxy = true;
}
catch (Exception ex)
{
MessageBox.Show("Error pinging host:'" + strIP + ":" + intPort .ToString() + "'");
return false;
}
return blProxy;
}
public void Proxy()
{
bool tt = PingHost(strIP ,intPort );
if(tt == true)
{
MessageBox.Show("tt True");
}
else
{
MessageBox.Show("tt False");
}
