在Ruby中使用Gmail API回复消息,可以通过以下步骤实现:
gem install google-api-client
gem install googleauth
gem install gmail
require 'google/apis/gmail_v1'
require 'googleauth'
require 'googleauth/stores/file_token_store'
require 'fileutils'
OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'.freeze
APPLICATION_NAME = 'Gmail API Ruby Quickstart'.freeze
CREDENTIALS_PATH = 'credentials.json'.freeze
TOKEN_PATH = 'token.yaml'.freeze
SCOPE = Google::Apis::GmailV1::AUTH_GMAIL_READONLY
def authorize
client_id = Google::Auth::ClientId.from_file(CREDENTIALS_PATH)
token_store = Google::Auth::Stores::FileTokenStore.new(file: TOKEN_PATH)
authorizer = Google::Auth::UserAuthorizer.new(client_id, SCOPE, token_store)
user_id = 'default'
credentials = authorizer.get_credentials(user_id)
if credentials.nil?
url = authorizer.get_authorization_url(base_url: OOB_URI)
puts 'Open the following URL in the browser and enter the ' \
"resulting code after authorization:\n" + url
code = gets
credentials = authorizer.get_and_store_credentials_from_code(
user_id: user_id, code: code, base_url: OOB_URI
)
end
credentials
end
def reply_to_message(service, user_id, message_id, reply_text)
message = service.get_user_message(user_id, message_id)
thread_id = message.thread_id
reply = Google::Apis::GmailV1::Message.new(
raw: Base64.urlsafe_encode64("To: #{message.payload.headers.find { |h| h.name == 'From' }.value}\n" \
"Subject: Re: #{message.payload.headers.find { |h| h.name == 'Subject' }.value}\n" \
"\n" \
"#{reply_text}")
)
service.send_user_message(user_id, reply, thread_id: thread_id)
end
def main
service = Google::Apis::GmailV1::GmailService.new
service.client_options.application_name = APPLICATION_NAME
service.authorization = authorize
user_id = 'me'
message_id = 'YOUR_MESSAGE_ID' # 替换为要回复的消息的ID
reply_text = 'YOUR_REPLY_TEXT' # 替换为要回复的内容
reply_to_message(service, user_id, message_id, reply_text)
end
main if __FILE__ == $PROGRAM_NAME
ruby your_script.rb
以上代码将使用Gmail API回复指定消息。你需要将YOUR_MESSAGE_ID
替换为要回复的消息的ID,将YOUR_REPLY_TEXT
替换为要回复的内容。
