如何将 JSON GET 请求转换为 HTTP PATCH 请求

Question

我想将 HTTP GET 请求转换为 HTTP PATCH 请求。我正在访问 TFS API，我想使用补丁请求自动锁定我的构建。

目前我正在通过 GET 方法获取所有信息。现在我想使用 HTTP PATCH 方法将 keepForever 从 false 更新为 true。通过 GET 方法我可以做到这一点，但现在我必须通过 HTTP Patch 方法做到这一点。

有人可以帮我将下面的代码从 GET 方法转换为 POST 方法吗？

public class Test_URL_Req {

    public static String getURLResponse(String url) {
        try {
            System.out.println("\nSending 'GET' request to URL : " + url);
            URL obj = new URL(url);
            HttpURLConnection con = (HttpURLConnection) obj.openConnection();
            con.setRequestMethod("GET");
            con.setRequestProperty("Accept", "application/json");
            int responseCode = con.getResponseCode();

            System.out.println("Response Code : " + responseCode);
            BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));

            String inputLine;
            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
                // System.out.println(response);
            }
            in.close();
            return response.toString();
        } catch (Exception e) {

您可以使用以下内容来构建 PATCH 请求。但是，您还应该确保您的服务器支持 PATCH，因为它通常不受支持。

 public static String getPatchResponse( String url){
      try {
          System.out.println("\nSending 'PATCH' request to URL : " + url);
          URL obj = new URL(url);
          HttpURLConnection con = (HttpURLConnection) obj.openConnection();
          con.setRequestMethod("PATCH");
          con.setRequestProperty("Accept", "application/json");
          int responseCode = con.getResponseCode();

          System.out.println("Response Code : " + responseCode);
          BufferedReader in = new BufferedReader(
                  new InputStreamReader(con.getInputStream()));

          String inputLine;
          StringBuffer response = new StringBuffer();
          while ((inputLine = in.readLine()) != null) {
              response.append(inputLine);
              //System.out.println(response);
          }
          in.close();
        return  response.toString();
      } catch (Exception e) {
          System.out.println(e);
      }
      return null;
  }
