Question

我想通过套接字将与ElasticSeach一起存储的UTF-8文本发送到应用程序。

我有一个ThreadedTCPServer已实现，这是应该处理回复的类。

我已经实现了基本的基于字符串的握手来分享一些信息，比如发送了查询，并且会发送回复。

class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler):

    def handle(self):
       es = Elasticsearch()
       #receive query from the client
       query = self.request.recv(1024)
       #Cut off the characters that aren't recognized
       query=query[2:]
       #for testing
       query=query.lower().strip().replace(' ','_')
       print query
       #Send response that query was received
       self.request.send("200...OK\n")
       res = es.search(index="painters",body={"query": { "match" :   {"title" : query}},"size":1  })
       if res['hits']['hits']:
           response = res['hits']['hits'][0]['_source']['text']
           self.request.send("201...RE\n")
       print response
       response=response.encode('utf-8')
       self.request.sendall(response)

在android方面，我有两个函数用于读取响应，一个用于读取字节。

    private String getResponse(InputStream is){
        String line="";
        BufferedReader rd = new BufferedReader(new InputStreamReader(is),8);
        try{
            line=rd.readLine();
        }
        catch (Exception e){
            Toast.makeText(MainActivity.this, "Stream Exception", Toast.LENGTH_SHORT).show();
        }
        return line;
    }

    private String convertStreamToString(InputStream is) {
        BufferedInputStream bi = new BufferedInputStream(is);
        byte[] b = new byte[1024];
        StringBuilder total = new StringBuilder();
        try {
            while (bi.read(b,0,1024)!=-1)
            {
                total.append(decodeUTF8(b));
                Log.d("TOTAL",decodeUTF8(b));
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        return total.toString();
    }

这是应解码字符串的函数：

String decodeUTF8(byte[] bytes) {
    return new String(bytes, UTF8_CHARSET);
}

问题是有时不是整个字符串显示在android端，当整个事情经历一些UTF-8字符最终变形（完全不同于发送的字符）

AsyncTask post执行启动新的Activty：

    protected void onPostExecute(String s) {
        //super.onPostExecute(s);
        if (s.contains("ECONNREFUSED")){
            Toast.makeText(MainActivity.this,"Connection Failed",Toast.LENGTH_LONG).show();
            return;
        }
        Intent intent = new Intent(MainActivity.this,ReplyActivity.class);
        intent.putExtra(EXTRA_MESSAGE,s);
        startActivity(intent);
    }

获取字符串的新意图：

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

    //get message
    Intent intent = getIntent();
    String summary = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);

示例输出：

早年（1928年至1949年）

安迪·沃霍尔（“né”Andrej Varhola，Jr。）于1928年8月6日出生于宾夕法尼亚州匹兹堡。他是Andrij Warhola的第四个孩子（美国化为Andrew Warhola，Sr。，1889 - 1942年）和JÃºlia（“née”ZavackÃ，1892年 - 1972年），w

正如你所看到的，即使从android发送查询到python，我也会得到一些我需要切断的垃圾。

这里：

       #Cut off the characters that aren't recognized
       query=query[2:]

再版（响应）：
