使用ActionMailer 的 STMP方式发送邮件

演示：

 class Tester< ActiveRecord::Base def self.send_mail MailPoster.deliver_file('receive@126.com','sender@126.com', 'public/images/rails.png', 'image/jpeg') end class MailPoster < ActionMailer::Base def file(to, sender, file_name, content_type) #standard ActionMailer message setup recipients to from sender subject subj #cc ["aaaa@126.com","bbbb@126com"] #cc %w{aaaa@126.com, bbbb@126.com} #setting the body explicitly means we don't have to provide a separate template file body "The main content: #{subj}" #set up the attachment attachment :content_type => content_type, :body => File.read(file_name), :filename => file_name.gsub(/.*///,'') end end ActionMailer::Base.smtp_settings = { :address => "smtp.126.com", :domain => "mail.126.com", :user_name => "youremail@126.com", :password => "your password", :authentication => :login, } end

 

运行：

$ script/runner Tester.send_mail

 

查看自己的邮件看看，如果有错误，请根据提示修改。

不需要的部分可以注释掉，如发送附件。

调用使用的方式是：[YourClass].deliver_[your method]

 

对于那些整站使用统一smtp服务器的，可以把以下代码移到config/environment.rb：

注意：代码要放到Rails::Initializer.run do |config| ... end 外面

ActionMailer::Base.smtp_settings = { :address => "smtp.126.com", :domain => "mail.126.com", :user_name => "youremail@126.com", :password => "your password", :authentication => :login, }

module ActionMailer # Usage: # # class ApplicationMailer < ActionMailer::Base # # Set up properties # # Properties can also be specified via accessor methods # # (i.e. self.subject = "foo") and instance variables (@subject = "foo"). # def signup_notification(recipient) # recipients recipient.email_address_with_name # subject "New account information" # body { "account" => recipient } # from "system@example.com" # end # # # explicitly specify multipart messages # def signup_notification(recipient) # recipients recipient.email_address_with_name # subject "New account information" # from "system@example.com" # # part :content_type => "text/html", # :body => render_message("signup-as-html", :account => recipient) # # part "text/plain" do |p| # p.body = render_message("signup-as-plain", :account => recipient) # p.transfer_encoding = "base64" # end # end # # # attachments # def signup_notification(recipient) # recipients recipient.email_address_with_name # subject "New account information" # from "system@example.com" # # attachment :content_type => "image/jpeg", # :body => File.read("an-image.jpg") # # attachment "application/pdf" do |a| # a.body = generate_your_pdf_here() # end # end # # # implicitly multipart messages # def signup_notification(recipient) # recipients recipient.email_address_with_name # subject "New account information" # from "system@example.com" # body(:account => "recipient") # # # ActionMailer will automatically detect and use multipart templates, # # where each template is named after the name of the action, followed # # by the content type. Each such detected template will be added as # # a separate part to the message. # # # # for example, if the following templates existed: # # * signup_notification.text.plain.rhtml # # * signup_notification.text.html.rhtml # # * signup_notification.text.xml.rxml # # * signup_notification.text.x-yaml.rhtml # # # # Each would be rendered and added as a separate part to the message, # # with the corresponding content type. The same body hash is passed to # # each template. # end # end # # # After this, post_notification will look for "templates/application_mailer/post_notification.rhtml" # ApplicationMailer.template_root = "templates" # # ApplicationMailer.create_comment_notification(david, hello_world) # => a tmail object # ApplicationMailer.deliver_comment_notification(david, hello_world) # sends the email # # = Configuration options # # These options are specified on the class level, like <tt>ActionMailer::Base.template_root = "/my/templates"</tt> # # * <tt>template_root</tt> - template root determines the base from which template references will be made. # # * <tt>logger</tt> - the logger is used for generating information on the mailing run if available. # Can be set to nil for no logging. Compatible with both Ruby's own Logger and Log4r loggers. # # * <tt>server_settings</tt> - Allows detailed configuration of the server: # * <tt>:address</tt> Allows you to use a remote mail server. Just change it from its default "localhost" setting. # * <tt>:port</tt> On the off chance that your mail server doesn't run on port 25, you can change it. # * <tt>:domain</tt> If you need to specify a HELO domain, you can do it here. # * <tt>:user_name</tt> If your mail server requires authentication, set the username in this setting. # * <tt>:password</tt> If your mail server requires authentication, set the password in this setting. # * <tt>:authentication</tt> If your mail server requires authentication, you need to specify the authentication type here. # This is a symbol and one of :plain, :login, :cram_md5 # # * <tt>raise_delivery_errors</tt> - whether or not errors should be raised if the email fails to be delivered. # # * <tt>delivery_method</tt> - Defines a delivery method. Possible values are :smtp (default), :sendmail, and :test. # Sendmail is assumed to be present at "/usr/sbin/sendmail". # # * <tt>perform_deliveries</tt> - Determines whether deliver_* methods are actually carried out. By default they are, # but this can be turned off to help functional testing. # # * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with delivery_method :test. Most useful # for unit and functional testing. # # * <tt>default_charset</tt> - The default charset used for the body and to encode the subject. Defaults to UTF-8. You can also # pick a different charset from inside a method with <tt>@charset</tt>. # * <tt>default_content_type</tt> - The default content type used for the main part of the message. Defaults to "text/plain". You # can also pick a different content type from inside a method with <tt>@content_type</tt>. # * <tt>default_mime_version</tt> - The default mime version used for the message. Defaults to nil. You # can also pick a different value from inside a method with <tt>@mime_version</tt>. When multipart messages are in # use, <tt>@mime_version</tt> will be set to "1.0" if it is not set inside a method. # * <tt>default_implicit_parts_order</tt> - When a message is built implicitly (i.e. multiple parts are assembled from templates # which specify the content type in their filenames) this variable controls how the parts are ordered. Defaults to # ["text/html", "text/enriched", "text/plain"]. Items that appear first in the array have higher priority in the mail client # and appear last in the mime encoded message. You can also pick a different order from inside a method with # <tt>@implicit_parts_order</tt>. class Base include AdvAttrAccessor, PartContainer private_class_method :new #:nodoc: cattr_accessor :template_root cattr_accessor :logger @@server_settings = { :address => "localhost", :port => 25, :domain => 'localhost.localdomain', :user_name => nil, :password => nil, :authentication => nil } cattr_accessor :server_settings @@raise_delivery_errors = true cattr_accessor :raise_delivery_errors @@delivery_method = :smtp cattr_accessor :delivery_method @@perform_deliveries = true cattr_accessor :perform_deliveries @@deliveries = [] cattr_accessor :deliveries @@default_charset = "utf-8" cattr_accessor :default_charset @@default_content_type = "text/plain" cattr_accessor :default_content_type @@default_mime_version = nil cattr_accessor :default_mime_version @@default_implicit_parts_order = [ "text/html", "text/enriched", "text/plain" ] cattr_accessor :default_implicit_parts_order # Specify the BCC addresses for the message adv_attr_accessor :bcc # Define the body of the message.
