❶ JAVA以POST方式提交XML獲取返回值(返回格式為XML)
URL url = new URL(requestUrl);
HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
httpUrlConn.setRequestMethod(「POST」);
OutputStream outputStream = httpUrlConn.getOutputStream();
outputStream.write(xml);
outputStream.close();
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
// 釋放資源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();
