Question

我收到此JSON从API解析JSON。安卓：</p> <pre><code>[{"name":"Lata de Atu00fan natural"}] </code></pre> <p>而且，当我得到的名称和值设置为一个TextView文本打印它​​而不是<code>Atún natural</code>：有特殊字符

我得到并解析了像这样的AsyncTask中的JSON。

DataOutputStream printout; 

    URL url = new URL(serverUrl+url_to); 
    HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
    conn.setRequestMethod("POST"); 
    conn.setReadTimeout(10000); // millis 
    conn.setConnectTimeout(15000); // millis 
    conn.setDoOutput(true); 
    conn.setRequestProperty("Accept-Charset", "UTF-8"); 
    conn.setRequestProperty("Host", "android.schoolportal.gr"); 
    conn.setRequestProperty("Accept-Language", "UTF-8"); 
    conn.setRequestProperty("Content-type", "application/json;charset=windows-1251"); 
    conn.connect(); 

    String str = this.data.toString(); 
    byte[] data_post=str.getBytes("UTF-8"); 

    // Send POST output. 
    printout = new DataOutputStream(conn.getOutputStream()); 
    printout.write(data_post); 
    printout.flush(); 
    printout.close(); 

    //Get Response 
    BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"), 8); 
    String line; 
    StringBuffer response = new StringBuffer(); 
    while((line = rd.readLine()) != null) { 
     response.append(line); 
     response.append('\r'); 
    } 
    rd.close(); 

    return response.toString(); 

任何想法？

Answer 1

\u00fa是一个unicode UTF-8编码字符。这不是一个Windows-1251编码的字符。所以这条线：

conn.setRequestProperty("Content-type", "application/json;charset=windows-1251"); 

应该是这样的：

conn.setRequestProperty("Content-type", "application/json;charset=UTF-8");

附录显示处理JSON数据。

在下面的代码中，我使用url.openStream()来简单地获取JSON数据。

new Thread(new Runnable() { 
    @Override 
    public void run() { 
     URL url = null; 
     try { 
      url = new URL(JSON_RESPONSE_URL); 
     } catch (MalformedURLException e) { 
      e.printStackTrace(); 
     } 

     try (InputStream inputStream = url.openStream(); 
      InputStreamReader inputStreamReader 
        = new InputStreamReader(inputStream, "UTF-8") 
     ) { 
      StringBuffer stringBuffer = new StringBuffer(); 
      char[] buffer = new char[BUFFER_SIZE]; 
      while (inputStreamReader.read(buffer, 0, BUFFER_SIZE) != -1) { 
       stringBuffer.append(buffer); 
      } 

      String jsonRaw = stringBuffer.toString(); 
      Log.d("RAW_STRING", jsonRaw); 

      // in the below three lines, parsing it as JSON data 
      JSONArray jsonArray = new JSONArray(jsonRaw); 
      JSONObject jsonObject = jsonArray.getJSONObject(0); 
      String jsonString = jsonObject.getString("name"); 
      Log.d("JSON_STRING", jsonString); 
     } catch (IOException | JSONException e) { 
      e.printStackTrace(); 
     } 
    } 
}).start(); 

结果是：

D/RAW_STRING: [{"name":"Lata de At\u00fan natural"}] 
D/JSON_STRING: Lata de Atún natural
