HttpPost (URLConnection)传参数中文乱码

 client.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 1000000);
         client.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 1000000);
         HttpPost post = new HttpPost(url);
         NameValuePair rq = new BasicNameValuePair("rq", requestObj.toString());
         BasicNameValuePair data_type = new BasicNameValuePair("type", req_type);
         NameValuePair sid = new BasicNameValuePair("sid", "web123");
         List<NameValuePair> list = new ArrayList<NameValuePair>();
         list.add(rq);
         list.add(sid);
         list.add(data_type);
         StringEntity entity = new UrlEncodedFormEntity(list, HTTP.UTF_8);
         post.setEntity(entity);
         HttpResponse res = client.execute(post);
         String respStr = EntityUtils.toString(res.getEntity(),HTTP.UTF_8);
         this.inputStream = new ByteArrayInputStream(respStr.toString().getBytes("utf-8"));
         return SUCCESS;

方式二：

 //1、URL对象创建一个应用程序与url之间链接urlconnection对象
         URL connectUrl = new URL(url);
         HttpURLConnection conn = (HttpURLConnection) connectUrl.openConnection();
         //2、设置属性
         //post请求必须设置的两个
         conn.setDoInput(true);
         conn.setDoOutput(true);
         //设置属性
         conn.setUseCaches(false);
         conn.setRequestProperty("accept", "*/*");
         conn.setRequestProperty("connection", "Keep-Alive");
         //打开与url之间的连接
         conn.connect();
         //如果使用URLconnection既要读取输入流 又要传参数 那么一定要先使用输出流 在使用输入流
         //getOutputStream 中包含了connect 也就是说使用了getoutputStream的时候connect可以不写
         OutputStream os = conn.getOutputStream();
         //设置编码 防止到服务端出现中文乱码
         OutputStreamWriter ow = new OutputStreamWriter(os, HTTP.UTF_8);
         PrintWriter pw = new PrintWriter(ow,true);
         //之前所有的参数只是写入写出流的缓存中并没有发送到服务端，执行下面这句话后表示将参数信息发送到服务端
         pw.println("rq="+requestObj.toString()+"&sid=web123&type="+req_type);
         pw.flush();
         //获取服务端返回的信息
         InputStream is = conn.getInputStream();
         //设置编码 防止读取到的数据乱码
         BufferedReader br = new BufferedReader(new InputStreamReader(is,HTTP.UTF_8));

         String line = null;
         String respStr = "";
         while((line=br.readLine())!=null){
             respStr+=line;
         }
         this.inputStream = new ByteArrayInputStream(respStr.toString().getBytes("utf-8"));
         return SUCCESS;

在服务端接收到requestObj.toString()中文乱码 可用在创建Entity时指定编码  StringEntity entity = new UrlEncodedFormEntity(list, HTTP.UTF_8);

在返回的数据中也出现了中文乱码 可使用EntityUtils.toString指定字符编码     String respStr = EntityUtils.toString(res.getEntity(),HTTP.UTF_8);
