Question

我正在尝试使用gmail API发送电子邮件，我在ruby中的代码运行良好，没有附件如下：

    client = google_client user_id
    token = Token.find_by_user_id(user_id)
    access_token = token.access_token
    gmail = Google::Apis::GmailV1::GmailService.new
    gmail.authorization = client
    message              = Mail.new
    message.date         = Time.now
    message.subject      = 'Supertram p'
    message.body         = "<p>Hi Alex, how's life?</p>"
    message.content_type = 'text/html'
    message.from         = self.email
    message.to           = 'email_name@gmail.com'

    msg = message.encoded
    message_object = Google::Apis::GmailV1::Message.new(raw:message.to_s)
    gmail.send_user_message('me', message_object)

成功发送html格式的电子邮件，我的问题是如何将文件附加到此邮件？有些人建议我使用add_file

client = google_client user_id
    token = Token.find_by_user_id(user_id)
    access_token = token.access_token
    gmail = Google::Apis::GmailV1::GmailService.new
    gmail.authorization = client
    message              = Mail.new
    message.date         = Time.now
    message.subject      = 'Supertramp'
    message.body         = "<p>Hi Alex, how's life?</p>"
    # message.content_type = 'text/html'
    message.from         = self.email
    message.to           = 'myemail@gmail.com'
    message.add_file("/Users/myname/Downloads/image.png")

    msg = message.encoded
    message_object = Google::Apis::GmailV1::Message.new(raw:message.to_s)
    gmail.send_user_message('me', message_object)

但这是我收到的消息：

- Content-Type：text / plain; charset = UTF-8 Content-Transfer-Encoding：7bit嗨Alex，生活怎么样？

- 内容类型：image / png; filename = image.png Content-Transfer-Encoding：base64 Content-Disposition：attachment;   filename = image.png内容ID：   ＆LT;

我只收到编码字符串，但没有附加文件。我的问题是如何通过附加的Gmail API发送电子邮件？

Answer 1

我认为你错过了关于attacment的事情

message              = Mail.new
message.date         = Time.now
message.subject      = 'Test Email'
message.body         = "<p>Hi Test, how's life?</p>"
message.content_type = 'text/html'
message.from         = "Test User <userone@example.com>"
message.to           = 'usertwo@example.com'

service = client.discovered_api('gmail', 'v1')

result = client.execute(
  api_method: service.users.messages.to_h['gmail.users.messages.send'],
  body_object: {
    raw: Base64.urlsafe_encode64(message.to_s)
  },
  parameters:  {
    userId: 'userone@example.com'
  },
    headers:   { 'Content-Type' => 'application/json' }
)

response = JSON.parse(result.body)

对于包含附件的多部分电子邮件：

message         = Mail.new
message.date    = Time.now
message.subject = 'Supertramp'
message.from    = "testone <userone@example.com>"
message.to      = 'testtwo@example.com'

message.part content_type: 'multipart/alternative' do |part|
  part.html_part = Mail::Part.new(body: "<p>Hi TEst, how's life?</p>", content_type: 'text/html; charset=UTF-8')
  part.text_part = Mail::Part.new(body: "Hi test, how's life?")
end

open('http://google.com/image.jpg') do |file| 
  message.attachments['image.jpg'] = file.read 
end

Rails：使用Gmail API发送电子邮件，附件仅返回编码文件
