android - Android 系统 WebView 中的 SSL 错误

Question

我需要在使用 Android System WebView“浏览器”的 Android 应用程序中显示我正在处理的内部网站。该站点的 SSL 在 Android、Linux 和 Windows 上的 Chrome 中正常工作，但是当我使用实现 WebView 的应用程序打开页面时，它返回 SSL 错误。该网站由 Nginx 提供服务，并使用我们公司来自 GoDaddy 的通配符 SSL 证书。我已经在运行 Android 7.1、8.0 和 8.1 的 Android 设备上进行了测试。我还从源代码编译了最新版本的 WebView 并将其安装在一台设备上，以确认旧版本不会导致问题。我跑了TestSSLServer针对网站的程序，没有收到任何警告。这是我的 Nginx 配置:

server {
    listen 443 ssl http2;
    server_name subdomain.example.com;
    root /websites/subdomain.example.com;

    ssl_certificate /etc/ssl/certs/wildcard_cert.crt;
    ssl_certificate_key /etc/ssl/private/wildcard_key.key;
    ssl_dhparam /etc/ssl/certs/dhparam.pem;

    location = /index.html {

}

在此先感谢您的帮助。

请在您的 webview 中添加以下内容

webView.enableJavaScript();
webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.setWebViewClient(new WebViewClient(){
        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

        }
    });
