Android庫使用asp.net web api

Question

我正在用asp.net web api構建一個web服務，以便與android應用程序交談。

有什麼好的和簡單的圖書館在那裏與android一起工作，使得連接到一個web服務快速和容易？

我正在尋找一些東西，將我排除在較低級別的網絡和線程上，並且我可以將我的安全性集成到其中。 （基於令牌的身份驗證）

我偶然發現了一個用於製作asyn http請求的庫，但我似乎無法再找到它。這就是爲什麼我想我會問別人正在使用什麼，看看會推薦什麼。

Answer 1

@Zapnologica：您可以結合本地HttpClient和Gson向ASP.NET Web API的REST Web服務發出請求，如post。如果你仍然真的想要先進的解決方案，那麼你可以使用AndroidAnnotations + Spring Framework + Gson像3.2.3這個post。不過，我建議您使用HttpClient的第一種方法，因爲您可以稍後輕鬆自定義您的代碼。

更新：

例如，HttpClient的方法，從第一篇文章，你可以做一個JSONHttpClient，它解析JSON對象爲您和發送到/從您的網絡服務接收

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; 
    }
