stackoverflow search api

Question

我想使用stackoverflow API的搜索方法，根据搜索关键字返回结果的json结构，然后在SearchResults div中显示这些结果（标题，描述和url）。

我是新来的C＃和我第一次尝试去是这样的：

protected void searchStockOverflow(string y) 
    { 

     var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.stackoverflow.com/1.1/search?intitle="+y); 
     httpWebRequest.ContentType = "text/json"; 
     httpWebRequest.Method = "POST"; 

     using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) 
     { 
      string json = "{ \"intitle\": \"" + y + "\"}"; 

      streamWriter.Write(json); 
     } 
     var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); 
     using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
     { 
      var responseText = streamReader.ReadToEnd(); 

      SearchResults.InnerHtml += "<div style='border:1px solid blue;margin:5px;'>"; 
      SearchResults.InnerHtml += responseText + "<br />"; 
      SearchResults.InnerHtml += "</div><br style='clear:both;' />"; 
     } 
    } 

问题是返回看起来像装饰符号垃圾 - 我猜是因为它是序列化，需要进行反序列化？

Answer 1

我肯定会说考虑使用REST客户端;然而，看看这些问题...通常您想要手动将数据反序列化为JSON，然后然后通过您的UI代码运行该数据。例如：

static void SearchStackOverflow(string y) 
{ 
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.stackoverflow.com/1.1/search?intitle=" + Uri.EscapeDataString(y)); 
    httpWebRequest.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
    httpWebRequest.Method = "GET"; 
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); 
    string responseText; 
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
    { 
     responseText = streamReader.ReadToEnd(); 
    } 
    var result = (SearchResult)new JavaScriptSerializer().Deserialize(responseText, typeof(SearchResult)); 
    .... do something with result ... 
} 
class SearchResult 
{ 
    public List<Question> questions { get; set; } 
} 
class Question 
{ 
    public string title { get; set; } 
    public int answer_count { get; set; } 
} 

从System.Web.Extensions.dll

使用JavaScriptSerializer

不幸的是，我在我的Mac上，无法对您的代码运行测试。您可能想要检查页面和返回的响应流的字符编码。如果它们不匹配;它可能会导致来自响应流的字符被错误地渲染，因此您看到垃圾。
