在 ASP.NET Core RC2 Web API 中,可以使用以下方法返回 HTTP 500 错误代码:
StatusCodeResult
类[HttpGet]
public IActionResult Get()
{
try
{
// your code here
}
catch(Exception ex)
{
return new StatusCodeResult(500);
}
}
public class CustomErrorHandlerMiddleware
{
private readonly RequestDelegate _next;
public CustomErrorHandlerMiddleware(RequestDelegate next)
{
_next = next;
}
public async Task Invoke(HttpContext httpContext)
{
try
{
await _next(httpContext);
}
catch(Exception ex)
{
httpContext.Response.StatusCode = 500;
httpContext.Response.ContentType = "text/plain";
await httpContext.Response.WriteAsync("An error occurred. Please try again later.");
}
}
}
将 middleware 添加到应用程序中:
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseMiddleware<CustomErrorHandlerMiddleware>();
// other middleware here
}
在 ASP.NET Core RC2 Web API 中,可以使用内置的 StatusCodeResult
类或自定义的错误处理器来返回 HTTP 500 错误代码。如果使用自定义的错误处理器,需要将其添加到应用程序中。
