}
解决方案:
在以代码中修改,将输入流转UTF-8,输出流转UFT-8
//输入流
//OutputStream os = conn.getOutputStream();
OutputStreamWriter os = new OutputStreamWriter(conn.getOutputStream(), “UTF-8”);

//输出流
//BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(),“UTF-8”));

//修改
// conn.setRequestMethod(“POST”);
// conn.setRequestProperty(“Content-Type”, “application/json;charset=utf-8”);
conn.setRequestProperty(“accept”, “/”);
conn.setRequestProperty(“connection”, “Keep-Alive”);
conn.setRequestProperty(“user-agent”,
“Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)”);
conn.setConnectTimeout(30 * 1000);
conn.setReadTimeout(180 * 1000);
// 发送POST请求必须设置如下两行
conn.setDoOutput(true);
conn.setDoInput(true);
