Android 中如何處理未經驗證的 HTTPS 連線？

Android 中未經驗證的 Https 連線

執行 HTTP(S) 要求時，如果遇到「SSL 異常不受信任的伺服器憑證」錯誤使用HTTPS時，您可能需要處理伺服器憑證驗證

解決方案：

要繞過憑證驗證並信任所有伺服器，可以實現以下程式碼：

// Ignore hostname verification
HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    @Override
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

// Trust all certificates
TrustManager[] trustAllCerts = new TrustManager[] {
    new X509TrustManager() {
        @Override
        public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

        @Override
        public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

        @Override
        public X509Certificate[] getAcceptedIssuers() {
            return new X509Certificate[] {};
        }
    }
};

// Install the all-trusting trust manager
try {
    SSLContext sc = SSLContext.getInstance("TLS");
    sc.init(null, trustAllCerts, new SecureRandom());
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
    e.printStackTrace();
}

// Open the connection, setting hostname verification to false and using the custom trust manager
HttpURLConnection http = null;
if (url.getProtocol().toLowerCase().equals("https")) {
    HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
    https.setHostnameVerifier(DO_NOT_VERIFY);
    http = https;
} else {
    http = (HttpURLConnection) url.openConnection();
}

使用此程式碼，對於正常的HTTP 和HTTPS 連接，都會跳過SSL 憑證驗證。
