为什么我不能从 docker 调用 api 端点

Question

我想运行在 docker 容器中

的 NET 5.0 控制台应用程序

using System;
using System.Threading.Tasks;
using Microsoft.AspNetCore.SignalR.Client;
using System.Net.Http;
using System.Threading;

namespace pi_worker
{
    class Program
    {
        private const string _url = "*server_url*";

        static async Task Main(string[] args)
        {                
            using (HttpClient client = new HttpClient())
            {
                await client.GetAsync($"{_url}/*endpointName*");
            }                     
        }
    }

我正在使用 docker 文件和命令构建我的容器：

docker build -t worker . docker run worker.

FROM mcr.microsoft.com/dotnet/runtime:5.0

COPY bin/Release/net5.0/publish .

ENTRYPOINT ["dotnet", "pi-worker.dll"]

但是对于第二个命令容器启动，我收到了这个错误

Unhandled exception. System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.

我尝试了一些 google 解决方案，但其中 none 有帮助

Answer 1

错误消息说您在 Docker 的工作人员无法识别您服务器的 SSL 证书。因此，无法建立 HTTPS 连接。为了修复它，您需要以某种方式将证书从您的服务器添加到存储在 docker 容器中的受信任证书中。这 article 可能会有所帮助。
