【问题描述】：

我有这个请求处理程序：

var httpClientHandler = new HttpClientHandler
{
    Proxy = new WebProxy(proxy.Address, proxy.Port),
    UseProxy = true
};

还有：

var url = new Url(hostUrl)
    .AppendPathSegment(pathSegment);

如何将请求处理程序添加到 FlurlClient？

【解决方案1】：

创建您自己的 ProxiedHttpClientFactory 覆盖 CreateMessageHandler() 方法：

public class ProxiedHttpClientFactory : DefaultHttpClientFactory
{
    private readonly string _proxyAddress;
    private readonly int _proxyPort;

    public ProxiedHttpClientFactory(string proxyAddress, int proxyPort)
    {
        this._proxyAddress = proxyAddress;
        this._proxyPort = proxyPort;
    }

    public override HttpMessageHandler CreateMessageHandler()
    {
        return new HttpClientHandler
        {
            Proxy = new WebProxy(this._proxyAddress, this._proxyPort),
            UseProxy = true
        };
    }
}

然后使用它：

var settings = new FlurlHttpSettings
{
    HttpClientFactory = new ProxiedHttpClientFactory("my.proxy.com", 8080)
};

var client = new FlurlClient(settings);

在现有的Url 实例上：

var url = new Url(hostUrl)
               .AppendPathSegment(pathSegment)
               .ConfigureClient(settings => settings.HttpClientFactory = new ProxiedHttpClientFactory("my.proxy.com", 8080));
