Question

我可以使用以下代码设置http代理：

public class CustomFlurlHttpClient : DefaultHttpClientFactory {
    public override HttpClient CreateClient(Url url, HttpMessageHandler m) {
        return base.CreateClient(url, CreateProxyHttpClientHandler("http://192.168.0.103:9090"));
    }

    private HttpClientHandler CreateProxyHttpClientHandler(string proxyUrl, string user = "", string passw = "") {
        NetworkCredential proxyCreds = null;
        var proxyUri = new Uri(proxyUrl);
        proxyCreds = new NetworkCredential (user, passw);
        var proxy = new WebProxy (proxyUri, false) {
            UseDefaultCredentials = false,
            Credentials = proxyCreds
        };
        var clientHandler = new HttpClientHandler {
            UseProxy = true,
            Proxy = proxy,
            PreAuthenticate = true,
            UseDefaultCredentials = false
        };
        if (user != "" && passw != "") {
            clientHandler.Credentials = new NetworkCredential (user, passw);
        }
        return clientHandler;
    }
}
class MainClass {
    public static void Main (string[] args) {
        run ();
        Console.ReadKey ();
    }

    async static void run() {
        using(FlurlClient client = new FlurlClient(c => { c.HttpClientFactory = new CustomFlurlHttpClient();})) {
            var result = await client.WithUrl("https://www.google.com").GetStringAsync();
            Console.WriteLine(result);
        };
    }
}

但不是socks代理。有什么想法怎么做？或支持async / await语法的任何其他（未弃用）rest客户端？

Answer 1

可能的解决方案是使用提供socks代理处理程序的Extreme.Net包。例如，从上面的代码中我们需要将CreateClient方法替换为：

        public override HttpClient CreateClient(Url url, HttpMessageHandler m)
    {
        var socksProxy = new Socks5ProxyClient("127.0.0.1", 9150);
        var handler = new ProxyHandler(socksProxy);
        return base.CreateClient(url, handler);
    }

它有效！

稍微好一点的选择是在自定义工厂中覆盖CreateMessageHandler而不是CreateClient：

public class CustomFlurlHttpClient : DefaultHttpClientFactory
{
    public override HttpMessageHandler CreateMessageHandler() {
        var socksProxy = new Socks5ProxyClient("127.0.0.1", 9150);
        return new ProxyHandler(socksProxy);
    }
}

C＃HttpClient tor socks4 / 5代理？
