ASP.NET/Mono MVC4 Web API v.1应用程序.
API控制器使用表单授权,并使用标准[Authorize]属性进行修饰.如果授权失败,则标准api错误消息
Authorization has been denied for this request.
发生.如何通过写入日志文件来识别此错误.返回给调用者shoudl的错误消息保持不变.如何添加额外的代码,这可以写入此错误消息与整个http请求标头和正文到日志文件?

代码需要在Windows 2003服务器中运行.我从回答中尝试了代码,但遇到了编译错误
Predefined type 'System.Runtime.CompilerServices.IAsyncStateMachine' is not defined or imported Cannot find all types required by the 'async' modifier. Are you targeting the wrong framework version, or missing a reference to an assembly? Cannot find all types required by the 'async' modifier.

实现此目的的一种方法是编写DelegatingHandler以在响应被发送回客户端之前拦截响应,然后记录有关返回错误的请求的信息.
public class RepsonseInterceptor : DelegatingHandler { protected async override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { var response = await base.SendAsync(request, cancellationToken); LogResponse(request, response); return response; } public void LogResponse(HttpRequestMessage request, HttpResponseMessage response) { HttpStatusCode status = response.StatusCode; //Catch the status codes you want to Log if (status == HttpStatusCode.NotFound || status == HttpStatusCode.Unauthorized || status == HttpStatusCode.InternalServerError) { //Do Logging Stuff here //with the Request and Response } } }
然后将其添加到Global.asax.cs中的Application_Start:
GlobalConfiguration.Configuration.MessageHandlers.Add(new ResponseInterceptor());
编辑:
如果您不想为所有路由执行处理程序,可以将它作为Per-Route消息处理程序添加到您想要的路由而不是全局路由,如下所示:
config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional }, constraints: null, handler: new ResponseInterceptor() );
如果您使用的是.NET Framework 4.0,则需要更改处理程序的SendAsync方法,如下所示:
protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { return base.SendAsync(request, cancellationToken) .ContinueWith(task => { var response = task.Result; LogResponse(request, response); return response; }); }
我认为如果你能从请求和响应对象中获取所需的所有信息,那么使用这个MessageHandler是合理的,尽管我还没有完全测试过.
