[英]Rails mail interceptor only for a specific mailer
I have an interceptor : DevelopmentMailInterceptor
and an inititializer setup_mail.rb
that initiates the interceptor. 我有一个拦截器:
DevelopmentMailInterceptor
和一个启动拦截器的inititializer setup_mail.rb
。
But I want to apply it to a specific mailer (to intercept NotificationMailer
and not the other ones. 但我想将它应用于特定的邮件程序(拦截
NotificationMailer
而不是其他邮件。
So I set in setup_mail.rb
: 所以我在
setup_mail.rb
设置:
`NotificationMailer.register_interceptor(DevelopmentMailInterceptor)
But then all mailers get intercepted, as if I'd written 但随后所有邮寄者都被拦截了,就像我写的一样
ActionMailer::Base.register_interceptor(DevelopmentMailInterceptor)
How can I filter this? 我该如何过滤?
I found the solution by exploring in depth the message
parameter of the delivering_email
method of the mailer interceptor. 我通过在深度探索找到的解
message
的参数delivering_email
邮件收发器拦截器的方法。
class DevelopmentMailInterceptor
def self.delivering_email(message)
filteredMailers = %w[
NotificationMailer
]
if filteredMailers.include?(message.delivery_handler)
message.subject = "[filter] To:#{message.to} - #{message.subject}"
message.to = 'logs@mail.com'
end
return message
end
end
@Intrepidd's answer remains true since the interceptor is applied to the whole Mail
class but I found the way around to what I wanted to achieve. @ Intrepidd的答案仍然是正确的,因为拦截器应用于整个
Mail
类,但我找到了实现我想要的方法。
You can't. 你不能。
Interceptor are registered on the global Mail
class (see the source of register_interceptor) 拦截器在全局
Mail
类上注册(参见register_interceptor的源代码)
If you need your interceptor to be effective only on specific e-mails, you should add a condition inside the interceptor class. 如果您需要拦截器仅对特定电子邮件有效,则应在拦截器类中添加一个条件。
