Android APP之WebView校验SSL证书的方法

webview.setWebViewClient(new WebViewClient() {  @Override  public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {if (error.getPrimaryError() == SslError.SSL_DATE_INVALID // 日期不正确  || error.getPrimaryError() == SslError.SSL_EXPIRED // 日期不正确  || error.getPrimaryError() == SslError.SSL_INVALID // webview BUG  || error.getPrimaryError() == SslError.SSL_UNTRUSTED) { // 根证书丢失  if (chkMySSLCNCert(error.getCertificate())) {    handler.proceed(); // 如果证书一致，忽略错误  }}  }    private boolean chkMySSLCNCert(SslCertificate cert) {byte[] MySSLCNSHA256 = { 35, 76, 110, -121, -68, -104, -12, 84, 39, 119, -55,  101, 95, -8, -90, 9, 36, -108, 5, -57, 76, -98, -19, -73, 91, -37, 18,  64, 32, -41, 0, 109 }; //证书指纹  Bundle bundle = SslCertificate.saveState(cert);  byte[] bytes = bundle.getByteArray("x509-certificate");  if (bytes != null) {  try {      CertificateFactory cf = CertificateFactory.getInstance("X.509");       Certificate ca = cf.generateCertificate(new ByteArrayInputSteam(bytes));       MessageDigest sha256 = MessageDigest.getInstance("SHA-256");      byte[] Key = sha256.digest(((X509Certificate) ca).getEncoded());      return Arrays.equals(key, MySSLCNSHA256);  } catch (Exception Ex) {}  }  return false;  }}
