AndroidHttpClient已棄用

Question

那麼，我的ImageDownloader類是與新的Sdk打破。我現在怎麼去做這項工作？任何可能我只需要替換下面的一些類而不對我的代碼做重大更改？在gradle這個文件

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2' 

或本：

static Bitmap downloadBitmap(String url) { 
     final AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); 
     final HttpGet getRequest = new HttpGet(url); 

     try { 
      HttpResponse response = client.execute(getRequest); 
      final int statusCode = response.getStatusLine().getStatusCode(); 
      if (statusCode != HttpStatus.SC_OK) { 
       Log.w("ImageDownloader", "Error " + statusCode + " while retrieving bitmap from " + url); 
       return null; 
      } 

      final HttpEntity entity = response.getEntity(); 
      if (entity != null) { 
       InputStream inputStream = null; 
       try { 
        inputStream = entity.getContent(); 
        final Bitmap bitmap = BitmapFactory.decodeStream(inputStream); 
        return bitmap; 
       } finally { 
        if (inputStream != null) { 
         inputStream.close(); 
        } 
        entity.consumeContent(); 
       } 
      } 
     } catch (Exception e) { 
      // Could provide a more explicit error message for IOException or IllegalStateException 
      getRequest.abort(); 
      Log.w("ImageDownloader", "Error while retrieving bitmap from " + url); 
     } finally { 
      if (client != null) { 
       client.close(); 
      } 
     } 
     return null; 
    } 

Answer 1

您可以使用此

android { 
    compileSdkVersion 23 
    buildToolsVersion '23.0.2' 
    useLibrary 'org.apache.http.legacy' //<-this line only 

或者你可以更新代碼，並使用HttpURLConnection這樣的：

URL url = new URL("your_url"); 
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); 
httpURLConnection.setReadTimeout(10000); 
httpURLConnection.setConnectTimeout(15000); 
httpURLConnection.setRequestMethod("POST"); 
httpURLConnection.setDoInput(true); 
httpURLConnection.setDoOutput(true); 
setupDataToDB(); 
OutputStream outputStream = httpURLConnection.getOutputStream(); 
BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(outputStream)); 
bufferedWriter.write(StringGenerator.queryResults(nameValuePairs)); 
bufferedWriter.flush(); 
bufferedWriter.close(); 
outputStream.close(); 
httpURLConnection.connect(); 
InputStream inputStream = new BufferedInputStream(httpURLConnection.getInputStream()); 

希望它有幫助！

Answer 2

您可以採取的InputStream：

HttpURLConnection urlConnection = null; 
try { 
    URL url = new URL(path); 
    urlConnection = (HttpURLConnection) url.openConnection(); 
    urlConnection.setConnectTimeout(CONNECTON_TIMEOUT_MILLISECONDS); 
    urlConnection.setReadTimeout(CONNECTON_TIMEOUT_MILLISECONDS); 
    inputStream = urlConnection.getInputStream(); 
    //add code to take bitmap here 
} finally { 
    if (urlConnection != null) { 
     urlConnection.disconnect(); 
    } 
} 

和比它採取位圖。
