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。
