c# - Asp.net 服务器应用程序正在本地主机上运行，​​但不在 Azure 中运行(未处理的异常渲染组件 : ExpectedJsonTokens)

Question

我创建了一个 Web 应用程序，这是我第一次将其引入 Azure。我已经遵循了所有步骤并获得了包含所有连接字符串的 SQL 等等。我可以从网址访问我的应用程序。然而，一旦我尝试从网络登录或注册，我就会遇到异常。

我做了什么:

已打开appsettings.json在我的 Visual Studio 解决方案中，并将连接字符串添加到 Azure SQL。然后在我的计算机上以 Debug模式运行我的应用程序并尝试注册一个新用户=>一切正常!因此，如果我从计算机 (https://localhost:7113/login) 访问 Azure SQL，则一切正常，我可以读取和写入数据库。如果我从https://xxx.azurewebsites.net/login做同样的事情我收到下面提到的错误。有什么想法为什么会这样以及如何解决吗？

这与设置 ap API 路由有关吗？

我的launchSettings.jason:

{
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:25391",
      "sslPort": 44337
    }
  },
  "profiles": {
    "MaDashWeb.Server": {
      "commandName": "Project",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "applicationUrl": "https://localhost:7113;http://localhost:5113",
      "dotnetRunMessages": true
    },
    "IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    },
    "Docker": {
      "commandName": "Docker",
      "launchBrowser": true,
      "launchUrl": "{Scheme}://{ServiceHost}:{ServicePort}",
      "publishAllPorts": true,
      "useSSL": true
    }
  }
}

我正在以这种方式构建解决方案模型:客户端、服务器、共享

我想知道这是否类似？:https://github.com/dotnet/aspnetcore/issues/29162

<小时/>

我在 CLient 项目中有 AuthorizeApi.cs，内容如下:

public async Task<RegisterResult> Register(RegisterModel registerModel)
{
  HttpResponseMessage response = await this.HttpClient.PostAsJsonAsync("api/Authorize/Register", registerModel);
  return await response.Content.ReadFromJsonAsync<RegisterResult>();
}

然后在服务器项目中我有带有以下代码的 Controller :

[Route("api/[controller]/[action]")]
[ApiController]
public class AuthorizeController : ControllerBase

...

[HttpPost]
public async Task<IActionResult> Register([FromBody] RegisterModel model)
{
  ApplicationUser newUser = new ApplicationUser
  {
    UserName = model.Email,
    Email = model.Email,
    FirstName = model.FirstName,
    LastName = model.LastName,
  };

...

谢谢Henk Holterman为 OP 指明正确的方向。将您宝贵的讨论作为答案发布，以帮助其他社区成员。

很高兴用户LG3通过转到日志流来解决他的问题，该日志流显示所有异常及其详细信息，这表明您指向了错误的文件路径并提到 reference给出了此类错误的解决方案，并且与 Henk Holterman 用户建议的相同，以另一种方式从 api/Authorize/Register 的浏览器开发工具检查准确的 URL> 打电话。
