无堆栈跟踪的错误详细信息

Question

在我的MVC WebApi服务中,当抛出异常时,它由过滤器处理:

public class GlobalExceptionFilter : ExceptionFilterAttribute {
    public override void OnException(HttpActionExecutedContext context) {
        context.Response = context.Request.CreateErrorResponse(HttpStatusCode.BadRequest, 
                                                               "Bad Request", 
                                                               context.Exception);
    } 
}

此过滤器生成的此HTTP响应取决于config.IncludeErrorDetailPolicy配置.

如果我设置config.IncludeErrorDetailPolicy到IncludeErrorDetailPolicy.Always,所有的细节都序列化到HTTP响应(Message,ExceptionMessage,ExceptionType和StackTrace).

如果我设置config.IncludeErrorDetailPolicy为IncludeErrorDetailPolicy.Never,则仅Message包括.

不过,我想包括Message,ExceptionMessage和ExceptionTypeHTTP响应,但不是StackTrace; 我该如何只排除StackTrace？或者我应该将所需的详细信息连接到Message字段中？

要在我的问题中添加一些上下文,客户端需要这些异常细节来处理特殊情况......但绝不是堆栈跟踪.

谢谢你指出我正确的方向莱昂.您的链接启发了我的解决方案.它保留CreateErrorResponse方法的功能并附加ExceptionMessage和ExceptionType属性.

public class GlobalExceptionFilter : ExceptionFilterAttribute {
    public override void OnException(HttpActionExecutedContext context) {
        context.Response = context.Request.CreateErrorResponse(HttpStatusCode.BadRequest, 
                                                               "Bad Request", 
                                                               context.Exception);
            var httpError = (HttpError)((ObjectContent<HttpError>)context.Response.Content).Value;
            if (!httpError.ContainsKey("ExceptionType"))
                httpError.Add("ExceptionType", context.Exception.GetType().FullName);
            if (!httpError.ContainsKey("ExceptionMessage"))
                httpError.Add("ExceptionMessage", context.Exception.Message);
    } 
}
