HttpURLConnection GET和POST请求示例

String _path = "http://*:8080/hpwy/token?appId=1234&secret=1234";
URL _url = new URL(_path);
HttpURLConnection _conn = (HttpURLConnection)  _url.openConnection();
InputStream _input;
byte[] _buffer = new byte[1024];
long _length = 0;
String _s;
_conn.setConnectTimeout(5 * 1000);
_conn.setRequestMethod("GET");
_conn.setDoInput(true);
_input = _conn.getInputStream();
_length = _input.read(_buffer);
_s = new String(_buffer,0, (int)_length);

if (null == _token || _token.length() <= 0)
return;
String _path = "http://*:8080/hpwy/login/phone";
String _stringEntity;
String _resultContent;
int _length;
byte[] _byteEntity;
byte[] _buffer = new byte[1024];
JSONObject _jsonEntity;
OutputStream _outputStream;
InputStream _inputStream;

_jsonEntity = new JSONObject();
_jsonEntity.put("phone", "1591234567");
_jsonEntity.put("token", _token);
_stringEntity = _jsonEntity.toString();
_byteEntity = _stringEntity.getBytes(Charset.forName("UTF-8"));
URL _url = new URL(_path);
HttpURLConnection _conn = (HttpURLConnection) _url.openConnection();
_conn.setConnectTimeout(5 * 1000);
_conn.setRequestMethod("POST");
_conn.setRequestProperty("accept", "*/*");
_conn.setRequestProperty("connection", "Keep-Alive");
_conn.setRequestProperty("Content-Type", "application/json");
_conn.setDoInput(true);
_conn.setDoOutput(true);

_outputStream = _conn.getOutputStream();
_outputStream.write(_byteEntity);
_outputStream.flush();

_inputStream = _conn.getInputStream();
_length = _inputStream.read(_buffer);

_resultContent = new String(_buffer, 0, _length);
Log.d("hpwy", _resultContent);
