Flutter on android CERTIFICATE_VERIFY_FAILED：证书已过期

Question

仅在 android 中的 flutter 上，对我的服务器的所有调用都会引发以下错误CERTIFICATE_VERIFY_FAILED: certificate has expired(handshake.cc:359))

从移动浏览器我的网站工作，也从 PC 浏览器，也从 flutter web。 仅来自 android 它说证书已过期。

我已经用 SSL Checker 进行了检查，一切都设置正确。 SSL 检查器的 Output：

$MYDOMAIN resolves to $MYIP
    
Server Type: Caddy
    
The certificate should be trusted by all major web browsers (all the correct intermediate certificates are installed).
    
The certificate was issued by Let's Encrypt.
    
The certificate will expire in 79 days.     
    
The hostname ($MYDOMAIN) is correctly listed in the certificate.

有人知道如何解决这个问题吗？

Answer 1

只需两步即可修复错误

1.创建自定义class扩展

    class CustomHttpOverrides extends HttpOverrides{
  @override
  HttpClient createHttpClient(SecurityContext? context){
    return super.createHttpClient(context)
      ..badCertificateCallback = (X509Certificate cert, String host, int      port)=> true;
  }
}

2.添加主线function

HttpOverrides.global = CustomHttpOverrides();
