我想使用laravel 5.3测试发送邮件，我正在使用mailable。但我收到此错误：class CollectionViewCell: UICollectionViewCell {
private var widthConstraint: NSLayoutConstraint?
...
override init(frame: CGRect) {
...
// Create width constraint to set it later.
widthConstraint = contentView.widthAnchor.constraint(equalToConstant: 0)
}
override func updateConstraints() {
// Set width constraint to superview's width.
widthConstraint?.constant = superview?.bounds.width ?? 0
widthConstraint?.isActive = true
super.updateConstraints()
}
...
}
我的环境配置是：
Connection could not be established with host mailtrap.io [Connection timed out #110]我还使用以下方法清除了缓存
：MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=465
MAIL_USERNAME=xxxxxxxxxxxxxx
MAIL_PASSWORD=xxxxxxxxxxxxxx
MAIL_ENCRYPTION=null
但仍然无法正常工作。
