linux下钉钉接口调用失败

同样的代码windows下面没有问题，发布到linux下时，获取accesstoken失败 java.io.IOException: HTTPS hostname wrong:  should be <oapi.dingtalk.com>


求解！！！
发起http请求的类，错误抛出在红色标记：

    public static JSONObject httpRequest(String requestUrl, String requestMethod, String outputStr)
                                                                                                   throws Exception {
        JSONObject jsonObject = null;
        StringBuffer buffer = new StringBuffer();
        // 创建SSLContext对象，并使用我们指定的信任管理器初始化
        TrustManager[] tm = { new MyX509TrustManager() };
        SSLContext sslContext = SSLContext.getInstance("SSL", "SunJSSE");
        sslContext.init(null, tm, new java.security.SecureRandom());
        // 从上述SSLContext对象中得到SSLSocketFactory对象
        SSLSocketFactory ssf = sslContext.getSocketFactory();
        //设置SSL客户端采用TLSv1协议
        System.setProperty("https.protocols", "TLSv1");
        URL url = new URL(requestUrl);
        HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
        httpUrlConn.setSSLSocketFactory(ssf);


        httpUrlConn.setDoOutput(true);
        httpUrlConn.setDoInput(true);
        httpUrlConn.setUseCaches(false);
        // 设置请求方式（GET/POST）
        httpUrlConn.setRequestMethod(requestMethod);
        httpUrlConn.setRequestProperty("Content-Type", "application/json; charset=utf-8");


        if ("GET".equalsIgnoreCase(requestMethod))
             httpUrlConn.connect();


        // 当有数据需要提交时
        if (null != outputStr) {
            OutputStream outputStream = httpUrlConn.getOutputStream();
            // 注意编码格式，防止中文乱码
            outputStream.write(outputStr.getBytes("UTF-8"));
            outputStream.close();
        }


        // 将返回的输入流转换成字符串
        InputStream inputStream = httpUrlConn.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "utf-8");
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);


        String str = null;
        while ((str = bufferedReader.readLine()) != null) {
            buffer.append(str);
        }
        bufferedReader.close();
        inputStreamReader.close();
        // 释放资源
        inputStream.close();
        inputStream = null;
        httpUrlConn.disconnect();
        jsonObject = JSONObject.fromObject(buffer.toString());


        return jsonObject;
    }
