为什么我在尝试从 gRPC 服务获取数据时得到 Grpc.Core.RpcException 写入 .net 核心

Question

我有一个 gRPC 服务（用 .net core 3.1 编写）部署在 windows 服务器中作为 kerstel 中的自托管服务运行。

我添加了以下配置以在 https.

中获取服务运行

"Kestrel": {
"EndpointDefaults": {
  "Protocols": "Http2"
},
"Endpoints": {
  "HttpsInlineCertFile": {
    "Url": "https://hostname:8081",
    "Protocols": "Http2",
    "Certificate": {
      "Path": "path to .pfx file",
      "Password": "Super secret password"
    }
  }
}

使用下面的代码

using GrpcChannel channel = GrpcChannel.ForAddress(httpsHost);
var client = new MyClient(channel);
var response = client.GetEntity(RequestCreator.GetRequest());
Console.WriteLine("Recieved: " + response.ToString());

我得到下面的异常，内部异常为空。

Status(StatusCode=Internal, Detail="Error starting gRPC call: The SSL connection could not be established, see inner exception.")

我应该添加什么来让客户端从服务中获取数据吗？

提前致谢

抱歉，我的问题回复晚了。问题是代理。我最终做的是创建一个 webproxy，将 gRPC 服务 url 添加到 bypassArrayList，创建 httpClientHandler，分配创建的 proyx，然后创建一个使用该 httpClientHandler 的 httpClient。

        var proxy = new WebProxy
        {
            Address = new Uri(proxyServer),
            UseDefaultCredentials = true,
            BypassProxyOnLocal = true,
            Credentials = CredentialCache.DefaultNetworkCredentials
        };

        proxy.BypassArrayList.Add(serviceUrl);

        var httpClientHandler = new HttpClientHandler
        {
            Proxy = proxy,
            DefaultProxyCredentials = CredentialCache.DefaultNetworkCredentials,
            UseDefaultCredentials = true,
            UseProxy = true,
        };
        var client = new HttpClient(httpClientHandler)
        {
            DefaultRequestVersion = HttpVersion.Version20
        };

        using var channel = GrpcChannel.ForAddress(serviceUrl, new GrpcChannelOptions
        {
            HttpClient = client
        });
