Python 2.7 telah mencapai akhir dukungan
dan akan dihentikan penggunaannya
pada 31 Januari 2026. Setelah penghentian penggunaan, Anda tidak akan dapat men-deploy aplikasi Python 2.7, meskipun organisasi Anda sebelumnya menggunakan kebijakan organisasi untuk mengaktifkan kembali deployment runtime lama. Aplikasi Python 2.7 yang ada akan terus berjalan dan menerima traffic setelah
tanggal penghentiannya. Sebaiknya Anda bermigrasi ke versi Python terbaru yang didukung.

Pesan email yang dikirim ke aplikasi Anda diimplementasikan sebagai permintaan HTTP yang berisi data
MIME. Untuk memproses pesan email masuk, kaitkan alamat email dengan pengendali skrip di konfigurasi aplikasi Anda, lalu sertakan pengendali dalam kode aplikasi Anda.
Email masuk menghasilkan permintaan HTTP, yang diteruskan ke skrip yang sesuai. Skrip yang menangani email masuk harus berada di layanan default Anda.
Untuk informasi selengkapnya tentang layanan Mail, lihat Ringkasan Mail API.
Mengonfigurasi aplikasi Anda untuk menerima email
Ketika Anda membuat aplikasi baru, email masuk dinonaktifkan secara default. Untuk mengaktifkan email masuk, Anda harus mengubah file app.yaml di layanan default.
Tambahkan bagian inbound_services yang mengaktifkan layanan email masuk.
Contoh:
inbound_services:-mail
Jika Anda tidak mengaktifkan email masuk dengan menyertakan bagian ini dalam file konfigurasi, email masuk akan dinonaktifkan, dan pesan email yang dikirim ke aplikasi akan diabaikan.
Tambahkan pemetaan yang mengaitkan alamat email yang dipetakan URL dengan pengendali skrip.
Untuk layanan default, alamat email untuk menerima email memiliki format berikut:
[STRING]@[Google Cloud projectID].appspotmail.com
Untuk layanan non-default, alamat email memiliki format berikut:
Pesan email dikirim ke aplikasi Anda sebagai permintaan POST HTTP menggunakan URL berikut, dengan [ADDRESS] sebagai alamat email lengkap, termasuk nama domain:
/_ah/mail/[ADDRESS]
Untuk menangani email masuk di aplikasi Anda, petakan URL email ke pengendali di file app.yaml:
Pada contoh di atas, /_ah/mail/.+ cocok dengan semua email yang dialamatkan ke aplikasi.
Jika ingin, Anda dapat menyiapkan beberapa pengendali untuk alamat email yang berbeda, seperti pada contoh berikut:
URL pesan email masuk dicocokkan dengan daftar ini dari awal hingga akhir. Jadi, jika URL pesan email cocok dengan lebih dari satu pola, pengendali pertama yang cocok akan dieksekusi. Dengan begitu, Anda dapat menyertakan pengendali "catchall" sebagai pemetaan terakhir. Pengendali berjalan dalam modul default (atau
versi aplikasi).
Buat subclass untuk InboundMailHandler dan ganti metode
receive().
Panggil metode receive() dengan argumen class InboundEmailMessage,
yang ditentukan oleh Python SDK.
Misalnya, Anda dapat membuat instance InboundEmailMessage seperti ini:
importloggingfromgoogle.appengine.ext.webapp.mail_handlersimportInboundMailHandlerimportwebapp2classLogSenderHandler(InboundMailHandler):defreceive(self,mail_message):logging.info("Received a message from: "+mail_message.sender)
InboundMailHandler berisi metode class praktis mapping() yang
menampilkan pasangan yang cocok dengan semua alamat email masuk ke pengendali email, dan tentu saja
Anda dapat memanggilnya pada subclass InboundMailHandler mana pun yang Anda kodekan:
Objek InboundEmailMessage (dalam contoh ini mail_message) berisi pesan email. Metode bodies() menampilkan isi dalam pesan. Jika Anda memanggil bodies() tanpa argumen, metode ini akan menampilkan iterator yang menghasilkan isi HTML terlebih dahulu, lalu isi teks biasa. Jika hanya menginginkan HTML atau teks biasa,
Anda dapat meneruskan argumen ke bodies():

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)."]]
