使用HttpWebRequest从404错误中检索内容 [英] Retrieve content from 404 error using HttpWebRequest

问题描述

我正在使用C＃与LinkedIn API集成。当我制作一个  无效 调用API时，它可以返回像这样的HTTP响应（来自
Fiddler）：

I am integrating with the LinkedIn API using C#. When I make an invalid call to the API, it can return a HTTP response like such (from Fiddler):

HTTP/1.1 404 Not Found
Server: Apache-Coyote/1.1
x-li-request-id: VL2EER2ROJ
Date: Tue, 16 Oct 2012 08:52:59 GMT
Vary: *
x-li-format: xml
Content-Type: text/xml;charset=UTF-8
Content-Length: 266

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<error>
  <status>404</status>
  <timestamp>1350377580000</timestamp>
  <request-id>VL2EER2ROJ</request-id>
  <error-code>0</error-code>
  <message>Could not find member {/people/XXXXXX}</message>
</error>

我特意想得到错误xml，但是HttpWebRequest似乎只是抛出异常然后无关在我的调试器中，我可以看到内容长度是266，但任何尝试调用  （System.Net.WebException） .Response.GetResponseStream（）结果
in  stream
不是可读 例外。

I would specifically like to get at the error xml, however HttpWebRequest seems to simply throw the exception and then has nothing to do with the content. In my debugger, I can see that the content length is 266, but any attempt to call (System.Net.WebException).Response.GetResponseStream()results in a stream was not readable exception.

这种在非200 HTTP状态响应中返回错误消息的方法在Web API中似乎很流行 - 我希望在那里是一种获得这些回复的方法......

This method of returning error messages within a non 200 HTTP status response seems quite popular in web APIs - I'm hoping there is a way to get at these responses...

推荐答案

不，默认情况下，我的代码是写的，因此无法通过未经授权的用户。

No, by default, my code is written so that it cannot be reproduced by an unauthorized user.
