Python 2.7은 지원이 종료되었으며 2026년 1월 31일에 지원 중단됩니다. 지원 중단 후에는 조직에서 이전에 조직 정책을 사용하여 레거시 런타임의 배포를 다시 사용 설정한 경우에도 Python 2.7 애플리케이션을 배포할 수 없습니다. 기존 Python 2.7 애플리케이션은 지원 중단 날짜 이후에도 계속 실행되고 트래픽을 수신합니다. 지원되는 최신 Python 버전으로 마이그레이션하는 것이 좋습니다.
수신 이메일 메시지의 URL이 목록의 처음부터 끝까지 대응되므로 이메일 메시지 URL이 둘 이상의 패턴과 일치하면 첫 번째 일치하는 핸들러가 실행됩니다. 이렇게 하면 마지막 매핑으로 '포괄' 핸들러를 포함할 수 있습니다. 핸들러는 기본 모듈(또는 애플리케이션 버전)에서 실행됩니다.
InboundMailHandler의 서브클래스를 만들고 receive() 메서드를 재정의합니다.
Python SDK에 정의된 InboundEmailMessage 클래스의 인수를 사용하여 receive() 메서드를 호출합니다.
예를 들어 다음과 같이 InboundEmailMessage의 인스턴스를 만들 수 있습니다.
importloggingfromgoogle.appengine.ext.webapp.mail_handlersimportInboundMailHandlerimportwebapp2classLogSenderHandler(InboundMailHandler):defreceive(self,mail_message):logging.info("Received a message from: "+mail_message.sender)
InboundMailHandler는 수신되는 모든 이메일 주소와 일치하는 결과 쌍을 메일 핸들러로 반환하는 편의 클래스 메서드인 mapping()을 포함하며, 코딩한 InboundMailHandler의 모든 서브클래스에서 이를 호출할 수 있습니다.
InboundEmailMessage 객체(이 예시의 mail_message)에는 이메일 메시지가 포함됩니다. bodies() 메서드는 메시지 내의 본문을 반환합니다. 인수 없이 bodies()를 호출하면 먼저 HTML 본문을 생성하고 그 후에 일반 텍스트 본문을 생성하는 반복기를 반환합니다. HTML 또는 일반 텍스트만 원하는 경우 bodies()에 인수를 전달합니다.

To process incoming email messages, you associate email addresses with\nscript handlers in your app configuration, then include the handlers in your\napp's code.\n| This page describes how to use the legacy bundled services and APIs. This API can only run in first-generation runtimes in the App Engine standard environment. If you are updating to the App Engine Python 3 runtime, refer to the [migration guide](/appengine/migration-center/standard/migrate-to-second-gen/python-differences) to learn about your migration options for legacy bundled services.\n\nIncoming email generates HTTP requests, which are passed to the appropriate\nscripts. The scripts that handle the incoming email must reside in your default\nservice.\n\nFor more information on the Mail service, see the\n[Mail API Overview](/appengine/docs/legacy/standard/python/mail).\n\nConfiguring your application to receive email\n---------------------------------------------\n\nWhen you create a new app, incoming email is disabled by default. To enable the\nincoming email, you must modify your `app.yaml` file in your default service.\n\n1. Add an `inbound_services` section that enables the incoming email service.\n For example:\n\n inbound_services:\n - mail\n\n If you don't enable incoming email by including this section in your\n configuration file, then incoming email is disabled, and email messages sent\n to the app are ignored.\n2. Add mappings that associate URL-mapped email addresses with script handlers.\n\n For the [default service](/appengine/docs/legacy/standard/python/configuration-files#the_default_service), the email address for receiving email has the following format: \n\n [STRING]@[Google Cloud project ID].appspotmail.com\n\n For non-default services, the email address has the following format: \n\n [STRING]@[servicename]-dot-[Google Cloud project ID].appspotmail.com\n\n Email messages are sent to your app as HTTP POST requests using the\n following URL, where \u003cvar translate=\"no\"\u003e[ADDRESS]\u003c/var\u003e is a full email address, including\n domain name: \n\n /_ah/mail/[ADDRESS]\n\n To handle incoming email in your app, map email URLs to handlers in the\n `app.yaml` file: \n\n - url: /_ah/mail/.+\n script: handle_incoming_email.app\n login: admin\n\n In the above example, `/_ah/mail/.+` matches all email addressed to the app.\n If you prefer, you can set up multiple handlers for different email\n addresses, as in the following example: \n\n - url: /_ah/mail/owner@.*your_app_id\\.appspotmail\\.com\n script: handle_owner.app\n login: admin\n - url: /_ah/mail/support@.*your_app_id\\.appspotmail\\.com\n script: handle_support.app\n login: admin\n - url: /_ah/mail/.+\n script: handle_catchall.app\n login: admin\n\n URLs of incoming email messages are matched to this list from first to last,\n so if an email message URL matches more than one pattern, the first matching\n handler will be the one executed. This allows you to include a \"catchall\"\n handler as the last mapping. The handlers run in the default module (or\n application version).\n\nHandling incoming email\n-----------------------\n\nThe Python SDK defines `InboundMailHandler`, a webapp class for handling\nincoming email. `InboundMailHandler` is in the\n[`google.appengine.ext.webapp.mail_handlers`](/appengine/docs/legacy/standard/python/refdocs/google.appengine.ext.webapp.mail_handlers)\npackage.\n\nTo use `InboundMailHandler`:\n\n1. Create a subclass for `InboundMailHandler` and override the `receive()` method.\n2. Call the `receive()` method with an argument of class `InboundEmailMessage`, defined by the Python SDK.\n\nFor example, you can create an instance of `InboundEmailMessage` like this: \n\n import logging\n\n from google.appengine.ext.webapp.mail_handlers import InboundMailHandler\n import webapp2\n\n\n class LogSenderHandler(InboundMailHandler):\n def receive(self, mail_message):\n logging.info(\"Received a message from: \" + mail_message.sender)\n\n| **Note:** Even if you are using the [webapp2](/appengine/docs/legacy/standard/python/tools/webapp2) framework, you still need to use the `InboundMailHandler` class provided by the old `webapp` framework. This handler is specific to the App Engine mail service, whereas webapp2 is provided by a third party.\n\n`InboundMailHandler` contains a `mapping()` convenience class method that\nreturns a pair matching all incoming email addresses to the mail handler and of\ncourse you can call it on any subclass of `InboundMailHandler` you code: \n\n app = webapp2.WSGIApplication([LogSenderHandler.mapping()], debug=True)\n\nThe `InboundEmailMessage` object (`mail_message` in this example) contains the\nemail message. Its `bodies()` method returns the bodies within the message. If\nyou call `bodies()` without arguments, it returns an iterator that yields HTML\nbodies first, then plain text bodies. If you want just HTML or just plain text,\nyou can pass an argument to `bodies()`: \n\n plaintext_bodies = mail_message.bodies('text/plain')\n html_bodies = mail_message.bodies('text/html')\n\n for content_type, body in html_bodies:\n decoded_html = body.decode()\n # ...\n\nThe `InboundEmailMessage` object includes attributes to access other message\nfields:\n\n- `subject` contains the message subject.\n- `sender` is the sender's address e.g. `\"Nobody \u003cnobody@example.com\u003e\"`.\n- `to` is a comma-separated list of the message's primary recipients e.g. `\"Joe \u003cjoe@example.com\u003e, Bill \u003cbill@example.com\u003e\"`.\n- `cc` contains a comma-separated list of the cc recipients e.g. `\"Joe \u003cjoe@example.com\u003e, Bill \u003cbill@example.com\u003e\"`.\n- `date` returns the message date.\n- `attachments` is a list of [`Attachment`](/appengine/docs/legacy/standard/python/refdocs/google.appengine.api.mail#google.appengine.api.mail.Attachment) objects, possibly empty.\n- `original` is the complete message, including data not exposed by the other fields such as email headers, as a Python [`email.message.Message`](http://docs.python.org/library/email.message.html).\n\nSimulating incoming messages with the local development server\n--------------------------------------------------------------\n\nOnce you set up your app to handle incoming email, you can use the\ndevelopment server console to simulate incoming email messages:\n\n1. Access the development server as an administrator by going to \u003chttp://localhost:8080/console\u003e and selecting **Sign in as administrator**.\n2. In the development server, click **Inbound Mail** in the navigation.\n3. Fill out the form that appears, and click **Send Email**.\n\n To learn more, including how to get the development server running, see\n [the Python Development Server](/appengine/docs/legacy/standard/python/tools/using-local-server)."]]
