如何解決 Android HTTPS POST 請求中的「ssl 異常：不受信任的伺服器憑證」錯誤？

Https 連接Android

在Android 中嘗試HTTPS POST 請求時，遇到「ssl 異常：不受信任的伺服器憑證」錯誤。儘管在 HTTP 下正常工作，HTTPS 呼叫失敗。

解決方案：

要繞過伺服器憑證驗證並建立HTTPS 連接，可以實現自訂信任管理器和主機名稱驗證器如下所示：

public static void trustAllHosts() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[]{};
        }

        public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }

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

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

// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

要使用這些設置，請將您的HTTPS 連接設定代碼修改為如下：

HttpURLConnection http = null;

if (url.getProtocol().toLowerCase().equals("https")) {
    trustAllHosts();
    HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
    https.setHostnameVerifier(DO_NOT_VERIFY);
    http = https;
} else {
    http = (HttpURLConnection) url.openConnection();
}
