我正在工作一个 asp .net core 6.0 web api 项目。

问题概述：

我遇到了一个问题。运行项目时，获取请求的响应为 200 ok。 但是在构建项目时，获取请求显示500Internal Server Error 并且在终端中我也遇到了错误。

细节：

当我使用dotnet run（托管环境：开发，端口为 7045 或 5032）运行项目时，https://localhost:7045/api/public/opayo-payment/retrieve-transaction/9A5CAE22-7109-D006-A017-41BF9F138076此获取请求的响应为200

但是当我使用 , 构建项目时dotnet publish -c Release （dotnet /home/PaymentApi.dll托管环境：生产，端口为 5000 或 5001）

并且， https://localhost:5001/api/public/opayo-payment/retrieve-transaction/9A5CAE22-7109-D006-A017-41BF9F138076这个获取请求的响应是500Internal Server Error

在终端我得到以下错误

在程序.cs

builder.Services.Configure<MerchantSessionConfig>(builder.Configuration.GetSection("Payments:TestOpayo"));
builder.Services.AddHttpClient<IOpayoPaymentService, OpayoPaymentService>("PublicOpayoApi", c =>
                c.BaseAddress = new Uri(builder.Configuration.GetValue<string>("Payments:TestOpayo:Url"))
                );

服务

private readonly HttpClient _client;
        private readonly IHttpClientFactory _clientFactory;
        private readonly MerchantSessionConfig _merchantSessionConfigoptions;

        private readonly DataDbContex _dataDbContex;

        public OpayoPaymentService(HttpClient client, IHttpClientFactory clientFactory, 
        IOptions<MerchantSessionConfig> options, DataDbContex dataDbContex)
        {                
            client = clientFactory.CreateClient("PublicOpayoApi");
            _clientFactory = clientFactory;
            _client = client;
            _merchantSessionConfigoptions = options.Value;
            _dataDbContex = dataDbContex;

            // Basic Authentication
            _client.DefaultRequestHeaders.Add("Accept", "application/json");
            var authenticationString = $"{_merchantSessionConfigoptions.Username}:{_merchantSessionConfigoptions.Password}";
            var base64EncodedString = Convert.ToBase64String(System.Text.ASCIIEncoding.UTF8.GetBytes(authenticationString));
            _client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", base64EncodedString);

        }

好的试试看：

应用设置.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "ConnectionStrings": {
    "DefaultConnection": "Server=<server>; port=5432; user id=postgres; password=<password>; database=<db>; Integrated Security=true; Pooling=true; CommandTimeout=300;Include Error Detail=true;Log Parameters=true"
  },
  "Payments": {
    "TestOpayo": {
      "Url": "https://pi-test.sagepay.com",
      "VendorName": "vendor",
      "Username": "username",
      "Password": "password"
    }
  }
}

您正在加载 -Payments:TestOpayo:Url从builder.Configuration.GetValue<string>("Payments:TestOpayo:Url")您的 appsettings 中加载。

所以你应该已经在你的 appsettings 中为生产环境配置了参数。

有一个约定.net 6 文档用于将 appsettings 映射到环境（开发、生产）。

看起来您Payments:TestOpayo:Url在生产应用程序设置中丢失了。

您还应该使用__as 分隔符来与平台无关，这会导致关键：Payments__TestOpayo__Url
