我在向 nifi 發送簡單的 PUT 請求時遇到問題，基本上我想用 java 代碼啟動一個 nifi 處理器。錯誤消息 - 服務器返回 HTTP 響應代碼：URL 為 405：http://localhost:8080/nifi-api/processors/我應該采取什么步驟來解決這個 405 問題？nifi api 網站提供了有關 rest api 的高級文檔，但沒有關于如何使用 Java 向 NiFi 發出正確 PUT 請求的指南。import java.io.BufferedReader;import java.io.DataOutputStream;import java.io.InputStreamReader;import java.net.HttpURLConnection;import java.net.URL;import javax.net.ssl.HttpsURLConnection;public class HttpURLConnectionExample {    private final String USER_AGENT = "Mozilla/5.0";    public static void main(String[] args) throws Exception {        HttpURLConnectionExample http = new HttpURLConnectionExample();        System.out.println("\nTesting 2 - Send Http POST request");        http.sendPut();    }    // HTTP PUT request    private void sendPut() throws Exception {        String url = "http://localhost:8080/nifi-api/processors/";        URL obj = new URL(url);        HttpURLConnection con = (HttpURLConnection) obj.openConnection();        //add reuqest header        con.setRequestMethod("PUT");        con.setRequestProperty("Content-Type", "application/json");        con.setRequestProperty("Accept", "application/json");        con.setRequestProperty("text/javascript", "*/*");        String urlParameters = "{\r\n" +                 "  \"status\": {\r\n" +                 "    \"runStatus\": \"RUNNING\"\r\n" +                 "  },\r\n" +                 "  \"component\": {\r\n" +                 "    \"state\": \"RUNNING\",\r\n" +                 "    \"id\": \"749b3133-0162-1000-9acc-f384457b160c\"\r\n" +                 "  },\r\n" +                 "  \"id\": \"749b3133-0162-1000-9acc-f384457b160c\",\r\n" +                 "  \"revisions\": {\r\n" +                 "    \"version\": 1,\r\n" +                 "    \"clientId\": \"550c4b84-0165-1000-37be-724ed17b5329\"\r\n" +                 "}\r\n" +                 "  ";    }}
