如何在Flurl中将代理用于Web请求? [英] How can I use proxies for web requests in Flurl?

问题描述

我使用Flurl客户端有一个简单的发布请求，我想知道如何使用代理使用IP，端口，用户名和密码等信息发出此请求.

I have a simple post request using the Flurl client, and I was wondering how to make this request using a proxy using information like the IP, port, username, and password.

string result = await atc.Request(url)
    .WithHeader("Accept", "application/json")
    .WithHeader("Content-Type", "application/x-www-form-urlencoded")
    .WithHeader("Host", "www.website.com")
    .WithHeader("Origin", "http://www.website.com")
    .PostUrlEncodedAsync(new { st = colorID, s = sizeID, qty = 1 })
    .ReceiveString();

您可以使用自定义工厂来做到这一点:

You can do this with a custom factory:

using Flurl.Http.Configuration;

public class ProxyHttpClientFactory : DefaultHttpClientFactory {
    private string _address;

    public ProxyHttpClientFactory(string address) {
        _address = address;
    }

    public override HttpMessageHandler CreateMessageHandler() {
        return new HttpClientHandler {
            Proxy = new WebProxy(_address),
            UseProxy = true
        };
    }
} 

要在启动时进行全局注册:

To register it globally on startup:

FlurlHttp.Configure(settings => {
    settings.HttpClientFactory = new ProxyHttpClientFactory("http://myproxyserver");
});
