Different Android Phone 使用不同的编码？

Question

我正在开发一个播放歌曲并与服务器通信的应用程序。这些方法是 addMusic、deleteMusic 和 requestMusicList。全部使用http GET方法。

案例如下：

deleteMusic 和 requestMusicList 在所有 phone 中工作正常。除了 addMusic，它只适用于某些 phone。

addMusic 仅适用于三星 phone。而在nuu、mi、meizu。这些是我们在这里得到的 phones，所以我们只用那些 phones 测试了应用程序。

我的问题：

由于addMusic url 字符串中包含的参数包含汉字，我认为这是问题的原因。这是日志。

从第一行可以看出，这包含我发送的URL。 URL 在标题参数下包含这些“张靓颖（电视剧《洋嫁》主题曲”）汉字。当服务器returns响应时，这些字符变成了“？？？？？？？？？？？”。

请注意，此问题仅出现在所述Android phones（mi、meizu 和nuu）中。三星，这从未发生过。

这是我的 addMusic 方法的代码：

public void addMusic(final Music music)
{
    new Thread(new Runnable() 
    {   
        @Override
        public void run() 
        {
            String contentURL = KEY_CONTENT_URL + "=" + music.mContentURL;
            String coverImageURLData = "&" + KEY_COVER_IMAGE_URL + "=" + music.mCoverImageURL;
            String deviceIDData = "&" + KEY_DEVICE_ID + "=" + mDeviceID;
            String duration = "&" + KEY_DURATION + "=" + Long.toString(music.mDuration);
            String timestamp = "&" + KEY_TIMESTAMP + "=" + Long.toString(System.currentTimeMillis()/1000);
            String  titleData = "&" + KEY_TITLE + "=" + music.mTitle.replaceAll("\s", "");
            String typeData = "&" + KEY_TYPE + "=" + music.mType;
            
            String dataArrayString = contentURL + coverImageURLData + deviceIDData + duration + timestamp + titleData + typeData;
            
            String key = "&" + KEY_KEY + "=" + KEY;
            String sign = "&" + KEY_SIGN + "=" + Utilities.getMD5String(dataArrayString + key);
            
            String parametersURL = dataArrayString + sign;

            try 
            {
                handleHttpResponse(mConnectionManager.get(URL_MAIN + URL_ADD_MUSIC + parametersURL), REQUEST_CODE_ADD_MUSIC);
            } 
            
            catch (IOException e) 
            {
                e.printStackTrace();
                
                mListener.onServerRequestFail(e.getLocalizedMessage());
            }
        }
    }).start();
}

Http GET 的代码如下：

public String get(String urlString) throws IOException
    {
        Log.v(LOG_TAG, "Get url string is " + urlString);
        
        URL url = new URL(urlString);
        
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("User-Agent", USER_AGENT);
     
        int responseCode = connection.getResponseCode();
        
        Log.v(LOG_TAG, "Response code from GET: " + responseCode);
        
        if(responseCode == RESPONSE_OK)
        {
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            
            StringBuffer response = new StringBuffer();
            String inputLine;
            
            while ((inputLine = reader.readLine()) != null) 
            {
                response.append(inputLine);
            }
            reader.close();
            
            return response.toString();
        }
        
        else
        {
            return ERROR_NO_RESPONSE;
        }
    }

我尝试检查 defaultCharset，它是所有 phone 测试的“UTF-8”。

我该如何解决这个问题？请帮忙。非常感谢

------------ 试过 URLEncoder.encode(music.mTitle.replaceAll("\s", ""), "UTF-8") ----- ----------

Answer 1

我解决了。感谢@Andy Turner 和@lorenzo-s 在评论中提供的提示。

我的错误是我在获取 MD5 校验和之前将字符串编码为 UTF-8。我注意到当我向服务器发送请求（URL编码）时，包含标题的响应是正确的。错误仅与 MD5 符号检查有关。

正确的做法是先获取MD5校验码，不对title参数进行编码。然后在将标题参数附加到 URL 字符串之前，将其转换为 UTF-8。

谢谢@Andy Turner 提醒我必须处理参数中的“&”。
