在APP开发过程中，后台使用的可能是自签的Https证书，如果不忽略证书校验，会出现Trust anchor for certification path not found的错误

WebView忽略HTTPS证书校验

        wv.setWebViewClient(new WebViewClient() {
            @Override
            public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
                handler.proceed();//忽略证书错误继续加载页面
            }
        });
