android客户端向服务端传汉字乱码问题
???? 最近在做android,遇到从android客户端向服务器端发送汉字乱码问题。采用URLConnection的GET方式，在客户端和服
?
务端都需要进行转码，而采用POST方式则不需要转码。具体方法如下：
????
? ? 用URLConnection从android发送数据有两种方式：
???? 第一种方式：采用get方式传值
??????? (1)客户端代码：
??????????????? ??URL url = new URL(mUrl);
?????????????? ? URLConnection urlConnection = url.openConnection();
?????????????? ??InputStream is = urlConnection.getInputStream();
??? ???????????? ?ByteArrayBuffer baf = new ByteArrayBuffer(50);
???? ???????????? int current = 0;
????????????????? while ((current = is.read()) != -1) {
??????????????????? ???baf.append((byte) current);
????????????????? }
???????????????? ?requestInfo = new String(baf.toByteArray(), "UTF-8").trim();
??? ???????????? ?is.close();
???
?????????????? ? 对汉字进行处理:
??????????????????? ?URLEncoder.encode(URLEncoder.encode(channelName, "UTF-8"), "UTF-8")
?????????? ? (2)服务器端接收字段：
?
???????????? URLDecoder.decode(URLDecoder.decode(request.getParameter("nickname"), "UTF-8"), "UTF-8")
???
???? ?第二种方式：采用Post方式：
?????????? ?? 客户端代码：
??????????????? ?public? String sendRemoteRequest(String path,String param){
??????????????????????????? ?Log.i("lisheng", param.toString());
??????????????????????????? ?Log.i("lisheng", path);
???????????????????????????? String strRes="";
???????????????????????????? ?OutputStream os = null;
????????????????????????? ???DataOutputStream dos = null;
???????????????????????? ???InputStream is = null;
???????????????????????? ??BufferedReader br = null;
??????????????????????? ?? try {
???????????????????????????????? ?? URL url = new URL(path);
?????????????????????????????????? ?URLConnection urlConn = url.openConnection();
????????????????????????????????? ??urlConn.setDoInput(true);
????????????????????????????????????urlConn.setDoOutput(true);
?????????????????????????????????? ??os = urlConn.getOutputStream();
??????????????????????????????? ??dos = new DataOutputStream(os);
?????????????????????????????? ?? dos.write(param.getBytes());
??????????????????????????????????dos.flush();
??????????????????????????????????dos.close();
??????????????????????????????? ??os.close();
???????????????????????????????? ?is = urlConn.getInputStream();
???????????????????????????????????br = new BufferedReader(new InputStreamReader(is,"UTF-8"));
????????????????????????????????? for (String strLine = ""; (strLine = br.readLine()) != null;)
????????????????????????????????????????? ?strRes = (new StringBuilder(String.valueOf(strRes))).append(strLine).toString();
??????????????????????????????? ?is.close();
????????????????????????????? ??} catch (MalformedURLException e) {
?????????????????????????????????????? e.printStackTrace();
?????????????????????????????? ??} catch (UnsupportedEncodingException e) {
??????????????????????????????????? ??e.printStackTrace();
????????????????????????????? ??} catch (IOException e) {
???????????????????????????????????????? ?e.printStackTrace();
????????????????????????????? ?}
???????????????????????????????? ???return strRes;
????????????????????????????? }
???????????????? ? 参数里直接写汉字
??????
???? 服务器端代码：
??
??request.setCharacterEncoding("UTF-8");
??request.getParameter("nickname")
???????
??即可得到参数为汉字的值，不需要转码。
