处理asp.net中的Web API错误的请求 [英] Handling bad request in asp.net web api

问题描述

我有一个API URL像下面我mvc4应用

I have a api url like below in my mvc4 app

http://localhost:15839/api/mydata/getdata/3365895543/PROBLEMDATA/myotherparam

现在的客户在消费上面的URL发送 HTT prequest 。在回应 API 正在发回一个响应。但在的网址用户的PROBLEMDATA 发送那些给我坏请求坏字符 - 无效的网址。我无法将客户端源强制EN code数据。我需要处理它在我的web API，并给回我的客户一个字符串不成功的。我所看到的这的WebAPI周期疑惑在这一点，我应该处理这个问题。可能是在HTTP消息处理程序，而是如何？

Now client is consuming the above url to send httprequest. In response api is sending back a response. but in PROBLEMDATA of the url user is sending bad characters that are giving me Bad Request - Invalid URL. I can't force my client source to encode data. i need to handle it in my web api and give back my client a string "Unsucessful". I have seen this webapi cycle wondering at which point I should handle this. probably at http message handler but How?

我可能需要按照这个。但寄存器（HttpConfiguration配置）也不会被打到

I may need to follow this. but Register(HttpConfiguration config) also doesn't get hit

推荐答案

我相信你可以通过重写的的Application_Error 方法。从那里，我想你可以生产的不成功的反应或转嫁给在控制器级别来处理请求。

I believe you can capture this globally by overriding the application_error method. From there I suppose you could produce the "unsucessful" response or pass the request along to be handled at the controller level.
