Question

我正在尝试使用java Web服务连接到Moodle。我需要做的是，验证moodle并将用户保存到其中。

任何人都可以在java中为我提供一些示例代码进行身份验证吗？这将是一个很大的帮助。

基本 REST MOODLE客户端的示例：

 import java.io.BufferedReader;
    import java.io.DataOutputStream;
    import java.io.IOException;
    import java.io.InputStream;
    import java.io.InputStreamReader;
    import java.net.HttpURLConnection;
    import java.net.ProtocolException;
    import java.net.URL;
    import java.net.URLEncoder;

    /**
     * REST MOODLE Client
     * It's very basic. You'll have to write the JavaObject2POST code.
     *
     */
    public class RestJsonMoodleClient {

        /**
         * Do a REST call to Moodle. Result are displayed in the console log.
         * @param args the command line arguments
         */
        public static void main(String[] args) throws ProtocolException, IOException {

            /// REST RETURNED VALUES FORMAT
            String restformat = "xml"; //Also possible in Moodle 2.2 and later: 'json'
                                       //Setting it to 'json' will fail all calls on earlier Moodle version
            if (restformat.equals("json")) {
                restformat = "&moodlewsrestformat=" + restformat;
