暂时禁用 SSL 验证（用于测试目的）

有时在开发或测试环境中，SSL 证书链可能尚未完全建立（尚未）。

要继续开发和测试，你可以通过安装全信任信任管理器以编程方式关闭 SSL 验证：

try {
   // Create a trust manager that does not validate certificate chains
   TrustManager[] trustAllCerts = new TrustManager[] {
      new X509TrustManager() {
       public X509Certificate[] getAcceptedIssuers() {
           return null;
       }
       public void checkClientTrusted(X509Certificate[] certs, String authType) {
       }
       public void checkServerTrusted(X509Certificate[] certs, String authType) {
       }
      }
   };

   // Install the all-trusting trust manager
   SSLContext sc = SSLContext.getInstance("SSL");
   sc.init(null, trustAllCerts, new java.security.SecureRandom());
   HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

   // Create all-trusting host name verifier
   HostnameVerifier allHostsValid = new HostnameVerifier() {
       public boolean verify(String hostname, SSLSession session) {
           return true;
       }
   };

   // Install the all-trusting host verifier
   HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
} catch (NoSuchAlgorithmException | KeyManagementException e) {
    e.printStackTrace();
}
