Android库使用asp.net web api

Question

我正在用asp.net web api构建一个web服务，以便与android应用程序交谈。

有什么好的和简单的图书馆在那里与android一起工作，使得连接到一个web服务快速和容易？

我正在寻找一些东西，将我排除在较低级别的网络和线程上，并且我可以将我的安全性集成到其中。 （基于令牌的身份验证）

我偶然发现了一个用于制作asyn http请求的库，但我似乎无法再找到它。这就是为什么我想我会问别人正在使用什么，看看会推荐什么。

@Zapnologica：您可以结合本地HttpClient和Gson向ASP.NET Web API的REST Web服务发出请求，如post。如果你仍然真的想要先进的解决方案，那么你可以使用AndroidAnnotations + Spring Framework + Gson像3.2.3这个post。不过，我建议您使用HttpClient的第一种方法，因为您可以稍后轻松自定义您的代码。

更新：

例如，HttpClient的方法，从第一篇文章，你可以做一个JSONHttpClient，它解析JSON对象为您和发送到/从您的网络服务接收

public class JSONHttpClient { 
    public <T> T PostObject(final String url, final T object, final Class<T> objectClass) { 
     DefaultHttpClient defaultHttpClient = new DefaultHttpClient(); 
     HttpPost httpPost = new HttpPost(url); 
     try { 

      StringEntity stringEntity = new StringEntity(new GsonBuilder().create().toJson(object)); 
      httpPost.setEntity(stringEntity); 
      httpPost.setHeader("Accept", "application/json"); 
      httpPost.setHeader("Content-type", "application/json"); 
      httpPost.setHeader("Accept-Encoding", "gzip"); 

      HttpResponse httpResponse = defaultHttpClient.execute(httpPost); 
      HttpEntity httpEntity = httpResponse.getEntity(); 
      if (httpEntity != null) { 
       InputStream inputStream = httpEntity.getContent(); 
       Header contentEncoding = httpResponse.getFirstHeader("Content-Encoding"); 
       if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) { 
        inputStream = new GZIPInputStream(inputStream); 
       } 

       String resultString = convertStreamToString(inputStream); 
       inputStream.close(); 
       return new GsonBuilder().create().fromJson(resultString, objectClass); 

      } 

     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } catch (ClientProtocolException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } catch (IOException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } 
     return null; 
    } 

    public <T> T PostParams(String url, final List<NameValuePair> params, final Class<T> objectClass) { 
     String paramString = URLEncodedUtils.format(params, "utf-8"); 
     url += "?" + paramString; 
     return PostObject(url, null, objectClass); 
    } 

    private String convertStreamToString(InputStream inputStream) { 
     BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream)); 
     StringBuilder stringBuilder = new StringBuilder(); 
     String line = null; 
     try { 
      while ((line = bufferedReader.readLine()) != null) { 
       stringBuilder.append(line + "\n"); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } finally { 
      try { 
       inputStream.close(); 
      } catch (IOException e) { 
       e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
      } 
     } 

     return stringBuilder.toString(); 
    } 

    public <T> T Get(String url, List<NameValuePair> params, final Class<T> objectClass) { 
     DefaultHttpClient defaultHttpClient = new DefaultHttpClient(); 
     String paramString = URLEncodedUtils.format(params, "utf-8"); 
     url += "?" + paramString; 
     HttpGet httpGet = new HttpGet(url); 
     try { 

      httpGet.setHeader("Accept", "application/json"); 
      httpGet.setHeader("Accept-Encoding", "gzip"); 

      HttpResponse httpResponse = defaultHttpClient.execute(httpGet); 
      HttpEntity httpEntity = httpResponse.getEntity(); 
      if (httpEntity != null) { 
       InputStream inputStream = httpEntity.getContent(); 
       Header contentEncoding = httpResponse.getFirstHeader("Content-Encoding"); 
       if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) { 
        inputStream = new GZIPInputStream(inputStream); 
       } 

       String resultString = convertStreamToString(inputStream); 
       inputStream.close(); 
       return new GsonBuilder().create().fromJson(resultString, objectClass); 

      } 

     } catch (UnsupportedEncodingException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } catch (ClientProtocolException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } catch (IOException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } 
     return null; 
    } 

    public boolean Delete(String url, final List<NameValuePair> params) { 
     DefaultHttpClient defaultHttpClient = new DefaultHttpClient(); 
     String paramString = URLEncodedUtils.format(params, "utf-8"); 
     url += "?" + paramString; 
     HttpDelete httpDelete = new HttpDelete(url); 

     HttpResponse httpResponse = null; 
     try { 
      httpResponse = defaultHttpClient.execute(httpDelete); 
      return httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_NO_CONTENT; 
     } catch (IOException e) { 
      e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates. 
     } 

     return false; 
    }
