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？
答案 0 :(得分：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
