如何使用.NET HttpWebRequest的API来读取响应HTTP头？ [英] How to read HTTP header from response using .NET HttpWebRequest API?

问题描述

我的应用程序目前使用OAuth与Twitter的API进行通信。在12月，Twitter的调升速率限制的OAuth每小时350请求。不过，我没有看到这一点。我仍然href=\"http://apiwiki.twitter.com/Twitter-REST-API-Method%3a-account%C2%A0rate_limit_status\">占到/ rate_limit_status 方法

My app currently uses OAuth to communicate with the Twitter API. Back in December, Twitter upped the rate limit for OAuth to 350 requests per hour. However, I am not seeing this. I am still getting 150 from the account/rate_limit_status method.

有人告诉我，我需要使用 X-RateLimit限额 HTTP头，以获得新的限速。然而，在我的代码，我没有看到这个头。

I was told that I needed to use the X-RateLimit-Limit HTTP header to get the new rate limit. However, in my code, I do not see that header.

下面是我的代码...

Here is my code...

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(newURL);
request.Method = "GET";
request.ServicePoint.Expect100Continue = false;
request.ContentType = "application/x-www-form-urlencoded";

using (WebResponse response = request.GetResponse())
{
    using (StreamReader reader = new StreamReader(response.GetResponseStream()))
    {
        responseString = reader.ReadToEnd();
    }
}

如果我检查响应，我可以看到它有标题属性，并有16头。不过，我没有 X-RateLimit限额列表

If I inspect the response, I can see that it has a property for Headers, and that there are 16 headers. However, I do not have X-RateLimit-Limit in the list.

任何想法，我做错了？

推荐答案

看原始响应文本（例如，使用Fiddler）。如果标题是不存在的，没有任何的C＃代码量会使其出现。 :)从你已经证明什么，似乎头是不是在回应

Look at the raw response text (e.g., with Fiddler). If the header isn't there, no amount of C# code is going to make it appear. :) From what you've shown, it seems the header isn't in the response.

更新：当我去：的 http://twitter.com/account/rate_limit_status.xml 没有 X-RateLimit限额头。但是，当我去 http://twitter.com/statuses/public_timeline.xml ，它的存​​在。因此，我认为你只需要使用不同的方法。

Update: When I go to: http://twitter.com/account/rate_limit_status.xml there is no X-RateLimit-Limit header. But when I go to http://twitter.com/statuses/public_timeline.xml, it's there. So I think you just need to use a different method.

它仍然说150，但！
