Https/ssl post方法可以在开发人员机器上工作，但不能在服务器上工作-java

Question

下面是连接到HTTPS/SSL的我的代码

public String readLinkInJson(String url, String data) throws MalformedURLException, IOException {
    URL obj = new URL(url);
    System.out.println(data);
    HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
    con.setHostnameVerifier(hv);
    con.setRequestMethod("POST");
    con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
    con.setRequestProperty("User-Agent", "Mozilla/5.0");
    con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
    con.setDoOutput(true);
    // For POST only - START
    try (OutputStream os = con.getOutputStream()) {
        os.write(data.getBytes("UTF-8"));
        os.flush();
    }
    // For POST only - END
    String inputLine;
    StringBuilder response = new StringBuilder();
    int responseCode = con.getResponseCode();
    if(responseCode >= 400){
    try (BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()))) {
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
    }
    }else{
    try (BufferedReader in = new BufferedReader(new InputStreamReader(con.getErrorStream()))) {
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
    }
    }
    return response.toString();

}

那我能做什么呢？请帮我找到正确的代码...

 TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                @Override
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }

                @Override
                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }

                @Override
                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
            }
        };

        try {
            SSLContext sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        } catch (GeneralSecurityException e) {
        }
