c# – Stackoverflow API响应格式

当C#创建HTTP GET请求时,Stackoverflow API返回意外响应.

如果我将http://api.stackoverflow.com/1.1/users/882993粘贴到浏览器地址栏中,我会得到正确的JSON响应：

{
  "total": 1,"page": 1,"pagesize": 30,"users": [
    {
      "user_id": 882993,"user_type": "registered","creation_date": 1312739131,"display_name": "Jack","reputation": 1926,"email_hash": "69243d90e50d9e0b3e025517fd23d1da","age": 23,"last_access_date": 1358087009,"website_url": "http://jtbrown.me.uk","location": "Birmingham,United Kingdom","about_me": "<p>Student.</p>\n","question_count": 68,"answer_count": 79,"view_count": 115,"up_vote_count": 98,"down_vote_count": 3,"accept_rate": 94,"association_id": "d64187a3-bf66-4a4d-8e87-6ef18f0397e3","user_questions_url": "/users/882993/questions","user_answers_url": "/users/882993/answers","user_favorites_url": "/users/882993/favorites","user_tags_url": "/users/882993/tags","user_badges_url": "/users/882993/badges","user_timeline_url": "/users/882993/timeline","user_mentioned_url": "/users/882993/mentioned","user_comments_url": "/users/882993/comments","user_reputation_url": "/users/882993/reputation","badge_counts": {
        "gold": 0,"silver": 7,"bronze": 34
      }
    }
  ]
}

如果我尝试在代码中执行相同的操作：

HttpWebRequest Request = WebRequest.Create("http://api.stackoverflow.com/1.1/users/882993") as HttpWebRequest;  

    using (HttpWebResponse Response = Request.GetResponse() as HttpWebResponse)  
    {  
        // Get the response stream  
        StreamReader Reader = new StreamReader(Response.GetResponseStream());

        // Console application output  
        StackWidget.Text = Reader.ReadToEnd();
    }

我收到了回复：

解决方法

您收到的HTTP响应是GZIP压缩的,因此您必须解压缩响应流.这可以通过设置 HttpWebRequest.AutomaticDecompression属性自动完成.

var request = (HttpWebRequest)WebRequest.Create("http://api.stackoverflow.com/1.1/users/882993");
request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; 
using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
using (var reader = new StreamReader(stream))
{
    var json = reader.ReadToEnd();
}
