使用Json向服务器发送补丁请求

Question

嗨，我正在尝试用Java修补JSONObject（或Json字符串），但我遇到了错误的请求。而且我不明白问题是出在Path-Methode还是JSONObject

PS：这是我第一次使用Server和Patch。我试图在网上查找，但没有任何帮助

感谢答案

这里是我的路径方法

public static  void pathMethod() throws IOException {
    HttpClient httpclient = HttpClientBuilder.create().build();
    JSONObject jsonData = getJsondata();

    HttpPatch req = new HttpPatch("http:URL");
    req.setHeader("Content-type", "application/json");
    if (jsonData != null) {
        final StringEntity stringData = new StringEntity(jsonData.toString());
        req.setEntity(stringData);
    }
    HttpResponse httpResponse = httpclient.execute(req);
    System.out.println(httpResponse);
}

此处为JSONObject

public static JSONObject getJsondata (){
    JSONObject j = new JSONObject(
            "{" +
            "\"op\": \"replace\"," +
            "\"path\": \"/name/family\"," +
            "  \"value\":  \"Paul\"" +
            " }"

    );
    return j;
}

谢谢
