HttpURLConnection请求后，返回数据出现乱码解决办法！

urlConn.setRequestMethod("POST");

urlConn.setUseCaches(false); //设置缓存

urlConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

urlConn.connect();



DataOutputStream dos = new DataOutputStream(urlConn.getOutputStream());

//这句：new InputStreamReader(urlConn.getInputStream(), "gbk") 设置编码

BufferedReader br = new BufferedReader(new InputStreamReader(urlConn.getInputStream(),"gbk"));

String line = "";

String result = "";

while(null != (line=br.readLine())){

result += line;

}

System.out.println("接到的数据: " + result);

show.setText(result);

br.close();

urlConn.disconnect();

} catch (Exception e) {

e.printStackTrace();

}



}

});
