Question

我的webview应用程序收到SSL错误。它会显示一条警告消息，询问是否加载网站。单击是按钮，它会通过忽略SSL错误来加载网站。但是当我重新加载同一个网站时，它没有向我显示处理错误的警告信息并直接加载网站。

所以，我的问题是如何在每次重新加载网站时让webview向我显示处理SSL错误的警告消息？

处理ssl错误的代码是``

                    if(error.getPrimaryError()==SslError.SSL_UNTRUSTED)
                    {

                        final Dialog sslalertdialog = new Dialog(browser.this);
                        sslalertdialog.setContentView(R.layout.sslerroralert);
                        sslalertdialog.show();
                        TextView sslalertmessage, sslalerttitle;
                        Button yes,no;
                        sslalertmessage= (TextView) sslalertdialog.findViewById(R.id.sslerrormessage);
                        sslalerttitle= (TextView) sslalertdialog.findViewById(R.id.sslerrorTitle);
                        String  message="The Website Security Certificate is Not Trusted." +
                                "One possible cause of this error is that a self-signed certificate is installed on the Website's server. " +
                                "Self-signed certificates aren't trusted by browsers because they are generated by Website's server, not by an accredited Certificate Authority (CA)." +
                                "Another cause of the error is that Someone is trying to intercept your communication." +
                                "You Should not Proceed,if you have never seen this error message for this Website before." +
                                "And if you want to proceed ,plz donot provide any sensitive Infomation to the site (like Credit Card Details " +
                                "Do you want to proceed anyways ?";
                        sslalerttitle.setText("The Website Cannot be Trusted!");
                        sslalertmessage.setText(message);
                        no=(Button) sslalertdialog.findViewById(R.id.NOBUTTON);
                        yes=(Button) sslalertdialog.findViewById(R.id.YES_BUTTON);
                        no.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                sslalertdialog.dismiss();
                                handler.cancel();
                            }
                        });
                        yes.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                sslalertdialog.dismiss();
                                handler.proceed();

                                padlock.setImageDrawable(getDrawable(R.drawable.ic_warning_red_400_24dp));

                            }
                        });

您可以使用WebView的clearSslPreferences（）函数：

webView.clearSslPreferences()

它将清除您对此WebView对象的决定，您可能会再次收到警告消息。

如何重新加载每次页面的WebView显示SSL错误？
