Question

에 너무 많은 리디렉션 :

java.net.ProtocolException: Too many redirects

아래의 내 코드입니다. 여기서 내가 뭘 잘못하고 있니?

private void savePrivateExternalFile(String fileURL, String fName) 
{ 
    CookieHandler.setDefault(new CookieManager(null, CookiePolicy.ACCEPT_ALL)); 
    HttpURLConnection connection = null; 
    URL url = null; 
    long startTime = System.currentTimeMillis(); 

    try 
    { 
     url = new URL(fileURL); 
     connection = (HttpURLConnection) url.openConnection(); 
     connection.addRequestProperty(BsharpConstant.WEB_SERVICES_COOKIES, cookie); 
     connection.setDoOutput(true); 
     connection.connect(); 

     File folderDir = null; 
     if (clickedItemId == 0) folderDir = new File(getExternalFilesDir("Product") + "/Brochure"); 
     else folderDir = new File(getExternalFilesDir("Product") + "/Videos"); 

     File file = new File(folderDir, fName); 

     if (file.exists()) file.delete(); 

     if (folderDir.isDirectory() || folderDir.mkdirs()) 
     { 
      InputStream inputStream = connection.getInputStream(); // Exception is thrown here !! 
      FileOutputStream fileOutputStream = new FileOutputStream(folderDir + "/" + fName); 

      int len = 0; 
      byte[] buffer = new byte[1024]; 

      if (clickedItemId == 1) 
      { 
       while ((le = inputStream.read(buffer)) != -1) 
       { 
        fileOutputStream.write(buffer, 0, len); 
       } 
      } 
      else 
      { 
       BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream, 1024 * 50); 
       while ((len = bufferedInputStream.read(buffer)) != -1) 
       { 
        fileOutputStream.write(buffer, 0, len); 
       } 
       bufferedInputStream.close(); 
       Log.i("Download", "download completed in " + ((System.currentTimeMillis() - startTime)/1000) + " sec"); 
      } 

      fileOutputStream.close(); 
      inputStream.close(); 

      editSharedPreferences.putString(fName, fName); 
      editSharedPreferences.commit(); 
     } 
     else 
     { 
      Toast.makeText(getApplicationContext(), BsharpUserMessage.UNABLE_TO_CREATE_THE_FOLDER, Toast.LENGTH_LONG).show(); 
     } 
    } 
    catch (Exception e) 
    { 
     e.printStackTrace(); 
    } 
}

Answer 1

나는이 한 살 알고 있지만,이 나오고 그래서 아무 대답이 없다 ..

내가 같은 문제가 있었다, 링크가 사적인 파이어 폭스에서 즉시 열리고 있었지만. 또한이 문제는 한 장치에서만 발생했으며 다른 세 장치에서는 문제가 없었습니다.

This answer worked for me

: 여기

코드입니다 (나는 몇 오타를 수정하고, 연결 대신 StringBuilder에 추가) :

 HttpClient httpClient = new DefaultHttpClient(); 
     httpClient.getParams().setParameter(ClientPNames.ALLOW_CIRCULAR_REDIRECTS, true); 
     HttpGet httpGet = new HttpGet(webLink); 
     HttpResponse response = httpClient.execute(httpGet); 
     StringBuilder responseBuilder = new StringBuilder(); 
     BufferedReader buffer = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); 
     String s = ""; 
     while ((s = buffer.readLine()) != null) 
      responseBuilder.append(s); 

     return responseBuilder.toString();
