SSL错误阻止网站登录混乱
干草,
作为Xamarin的替代品,我试图在flutter中创建具有相同功能的应用程序。但是,webview插件/软件包不适用于自签名的ssl证书。在Xamarin中,有一种方法可以处理ssl错误并仍然加载网站。
当前代码:
@override void initState() {
super.initState();
final flutterWebviewPlugin = new FlutterWebviewPlugin();
flutterWebviewPlugin.onHttpError.skip(1000);
flutterWebviewPlugin.launch("https url to website", hidden: true,
allowFileURLs: true,
appCacheEnabled: true,
withJavascript: true,
withLocalStorage: true,
withZoom: true);
flutterWebviewPlugin.onHttpError.skip(1000);
flutterWebviewPlugin.onStateChanged((state) async)
{
flutterWebviewPlugin.evalJavascript(
"document.getElementById(\"name\").innerText = \"username\"");
flutterWebviewPlugin.evalJavascript(
"document.getElementById(\"password\").innerText = \"pw\"");
flutterWebviewPlugin.evalJavascript(
"document.getElementById(\"loginbutton\").invokeMember(\"click\")");
var test = flutterWebviewPlugin.evalJavascript(
"document.getElementById(\"errorbox\").innerText");
};
flutterWebviewPlugin.dispose();
flutterWebviewPlugin.close();
错误:
Failed to validate the certificate chain, error: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
有没有比用Java和Swift编写自己的程序包或自定义WebView更好的方法了?
回答:
在Android上,您可以修改插件。将副本克隆到本地计算机,并向其中添加其他替代flutter_webview_plugin/android/src/main/java/com/flutter_webview_plugin/BrowserClient.java
public void onReceivedSslError (WebView view, SslErrorHandler handler,
SslError error) 用简单的实现覆盖handler.proceed()
假设您的项目在其中/projects/myproject
,并将插件克隆到中/projects/flutter_webview_plugin
。在中进行更改/projects/flutter_webview_plugin/android/src/.../BrowserClient.java
。然后使用更新pubspec.yaml
项目(用替换flutter_webview_plugin的现有条目):
dependencies: flutter_webview_plugin:
path: ../flutter_webview_plugin
