HTTP客户端代码片段

代码片段：

public HttpURLConnection connection = null;

设置connection属性
URL url = new URL(urlPath);
connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setUseCaches(false);
connection.setInstanceFollowRedirects(true);
connection.setRequestProperty("Content-type", "application/json");
connection.setRequestProperty("Content-encoding", "GBK");
//connection.setRequestProperty("Content-encoding", "UTF-8");
connection.setRequestProperty("Accept", "application/json");
connection.connect();



发送请求
output = connection.getOutputStream();
output.write(request.getBytes());
output.flush();

接受响应
reader = new BufferedReader(new InputStreamReader(
                connection.getInputStream()));
String st;
StringBuffer stb = new StringBuffer();
while (null != (st = reader.readLine())) {
stb.append(st);
}


关闭connection
if (null != connection) {
            connection.disconnect();
        }
