Question

我正在寻找便携式替代Mono HttpClient堆栈。便携式Mono版本[常规Mono堆栈的一部分]有bug。我一直在尝试修复影响我们项目的一个特定错误。由于异步操作所需的库的高度异步性，Mono代码中缺少文档和注释，因此需要很长时间。我看到微软并不打算在C＃中实现Http堆栈，而是使用可靠的库 - WinHttp和libcurl。不幸的是，将libcurl移植到Mono也是一项工作。从法律上讲，HttpClient允许替换处理程序，创建一个替代堆栈。适用于iOS和适用于iOS / Android和其他平台的ModernHttpClient的CFNetwork处理程序。然而，对于我来说，ModernHttpClient对我来说也不起作用。有什么建议？我的代码如下：

class Program
{
    static void Main(string[] args)
    {
        var threadCancelationToken = new CancellationTokenSource();
        var sl = new StatusLoop();
        sl.HttpClientTimeout = int.Parse(args[0]);
        sl.StatusFreq = int.Parse(args[1]);

       Task.Run(async () => await sl.RunStatusLoop(threadCancelationToken.Token), threadCancelationToken.Token);
       Console.ReadKey();
    }
}

public class StatusLoop
{
    public int HttpClientTimeout;
    public int StatusFreq;

    public async Task RunStatusLoop(CancellationToken cancellationToken)
    {
//       var handler = new HttpClientHandler
         var handler = new NativeMessageHandler
         {
            Credentials = new NetworkCredential("username", "password"),
            PreAuthenticate = true,
            UseProxy = false
         };

//       var httpClient = new HttpClient(new NativeMessageHandler())
         var httpClient = new HttpClient(handler)
         {
             Timeout = TimeSpan.FromSeconds(this.HttpClientTimeout)
         };

         httpClient.DefaultRequestHeaders.Add("Connection", "Keep-Alive");
         httpClient.DefaultRequestHeaders.ExpectContinue = false;

         ServicePointManager.ServerCertificateValidationCallback +=
    (sender, certificate, chain, sslPolicyErrors) => true;

        while (true)
        {
            try
            {
                var httpResponse = await httpClient.GetAsync("https://192.168.1.22/api/v1/system/status/", cancellationToken);
                if (httpResponse.IsSuccessStatusCode)
                    Console.Write(".");
            }
            catch (Exception ex)
            {
                Console.WriteLine ("HttpClientGetStatus - exception\n\r" + ex.ToString());
            }

            Thread.Sleep(this.StatusFreq * 1000);
        }
    }
}

如果您在Linux / Mac上使用过替代的HttpClientHandler，请分享您的经验。

谢谢

有一个here来源，但我不知道nuget package是否包含此Unix代码

用于Linux / Unix的替代HttpClientHandler
