Android HttpURLConnection、最初の4066シンボルのみを読み込み、要求を破棄します

Question

問題は完全な結果が得られないことです。そして、唯一のいくつかの部分、それは売上の一部ではなく、最初の4066 characters.The問題が同じで、IOExceptionが

private class GetContent extends AsyncTask<Void, Void, String>{ 

    HttpURLConnection urlConnection = null; 
    BufferedReader reader = null; 
    String resultJson = ""; 

    @Override 
    protected String doInBackground(Void... params) { 

     try{ 
      URL url = new URL("http://www.json-generator.com/api/json/get/bSFiRdwiSq?indent=2"); 

      urlConnection = (HttpURLConnection)url.openConnection(); 
      urlConnection.setRequestMethod("GET"); 
      urlConnection.connect(); 

      InputStream inputStream = urlConnection.getInputStream(); 
      StringBuffer buffer = new StringBuffer(); 

      reader = new BufferedReader(new InputStreamReader(inputStream)); 

      String line; 
      while ((line = reader.readLine()) != null){ 
       buffer.append(line); 
      } 

      resultJson = buffer.toString(); 

      Log.d("Result:", resultJson); 

     } catch (MalformedURLException e) { 
      e.printStackTrace(); 

     } catch (IOException e) { 
      e.printStackTrace(); 
     } 

     return null; 
    } 
}` 

結果

Answer 1

コードに実装する必要がある点はほとんどありません。

1. urlConnection.connect（）; urlConnection.getInputStream（）;を呼び出すときに重要ではありません。自動的にURLを呼び出します。

2. あなたが開くすべてのストリームを閉じます。

ので、コードが

private class GetContent extends AsyncTask<Void, Void, String>{ 

HttpURLConnection urlConnection = null; 
BufferedReader reader = null; 
String resultJson = ""; 

@Override 
protected String doInBackground(Void... params) { 

    try{ 
     URL url = new URL("http://www.json-generator.com/api/json/get/bSFiRdwiSq?indent=2"); 

     urlConnection = (HttpURLConnection)url.openConnection(); 
     urlConnection.setRequestMethod("GET"); 

     InputStream inputStream = urlConnection.getInputStream(); 
     BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream,"UTF-8")); 
     StringBuilder builder = new StringBuilder(); 
     int line; 
     while ((line=reader.read()) > 0){ 
      builder.append((char)line); 
     } 
     reader.close(); 
     inputStream.close(); 
     String resultJson = builder.toString(); 

     Log.d("Result:", resultJson); 

    } catch (MalformedURLException e) { 
     e.printStackTrace(); 

    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    return null; 
} 
} 

Answer 2

あなたによって引き起こされているように見えません読み取りロジックは次のようになります。

InputStream in = mConnection.getInputStream(); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in, enconding));  
int ch; 
StringBuilder sb = new StringBuilder();   

while ((ch=reader.read()) > 0) {    
    sb.append((char)ch); 
} 

String resultjson= sb.toString().trim(); 
Log.d("Result:", resultJson);
