  To address the garbled character issue and unify the error response format for invalid tenants in your ABP commercial application, you should adjust the way tenant-not-found errors are handled and returned by your backend.

  Problem Analysis

  • The commercial version returns an HTML error page with encoded characters for non-English languages (e.g., zh-Hans), while the community version returns a JSON error object.
  • This difference is due to the built-in error handling pipeline in the commercial edition, which by default returns an HTML error page for certain errors, especially when localization is involved.

  Solution Steps

  1. Force JSON Error Responses for API Endpoints

  You can globally configure your API to always return JSON error responses (like the community version) by customizing the exception handling middleware. In your Startup or module configuration, add the following:

  public override void ConfigureServices(ServiceConfigurationContext context)
  {
      Configure<AbpExceptionHandlingOptions>(options =>
      {
          options.SendExceptionsDetailsToClients = true;
          options.ExceptionHandlingPath = "/api/error"; // Ensure this path returns JSON
      });
  }
  

  2. Add a Custom Exception Filter (Optional)

  If you want to ensure all errors (including tenant not found) are returned as JSON, you can add a global exception filter:

  public class JsonExceptionFilter : IExceptionFilter
  {
      public void OnException(ExceptionContext context)
      {
          context.Result = new JsonResult(new
          {
              error = new
              {
                  code = "Volo.AbpIo.MultiTenancy:010001",
                  message = context.Exception.Message
              }
          })
          {
              StatusCode = StatusCodes.Status400BadRequest
          };
          context.ExceptionHandled = true;
      }
  }
  
  // Register in ConfigureServices
  context.Services.Configure<MvcOptions>(options =>
  {
      options.Filters.Add<JsonExceptionFilter>();
  });
  

  3. Ensure API Controllers Use [ApiController]

  Make sure your API controllers are decorated with [ApiController] to enforce content negotiation and JSON responses.

  4. Check Localization Files

  If you want to customize the error message, update your localization files for the relevant language (e.g., zh-Hans) to ensure proper translation and encoding.

  5. Temporary Workaround

  If you need a quick fix, you can set the Accept header to application/json in your client requests to force the backend to return JSON:

  --header 'Accept: application/json'
  

  Summary

  • Configure exception handling to always return JSON for API endpoints.
  • Optionally, add a global exception filter for consistent error formatting.
  • Use the Accept: application/json header as a temporary workaround.

  This will make your commercial edition's error responses consistent with the community edition and resolve the character encoding issue.
