flutter使用Charles代理爬虫

class MyHttpOverrides extends HttpOverrides {
  bool _badCertificateCallback(X509Certificate cert, String host, int port) {
    return true;
  }

  @override
  HttpClient createHttpClient(SecurityContext? context) {
    return super.createHttpClient(context)
      ..badCertificateCallback = _badCertificateCallback
      ..findProxy = (uri) {
        return 'PROXY 192.168.1.193:8888;DIRECT;';//192.168.1.193:8888是代理ip端口

     }
    ;
  }
}

    HttpOverrides.global = MyHttpOverrides();
