    query = '(from OR to OR cc):u****@*******.co.jp'
    results = service.users()\
        .messages()\
        .list(userId='me', q=query)\
        .execute()
    print(results)

結果 (雰囲気)

{
  'messages': [{'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'},
              {'id': '16*********', 'threadId': '16************'}],
 'resultSizeEstimate': 23
}

ここまでだと、あくまで個別にアクセスするための ID 情報だけが取れるっぽい

snippet だとメッセージ本文全体が取れないんだよなー payload.body からじゃないとダメそう

laughk commented 5 years ago

payload.body, base64url って形式で encode されてるみたい

https://developers.google.com/gmail/api/v1/reference/users/messages/attachments#resource

The body data of a MIME message part as a base64url encoded string. May be empty for MIME container types that have no message body or when the body data is sent as a separate attachment. An attachment ID is present if the body data is contained in a separate attachment.

なんか文字コード壊れてる... ? なんか上手く decode できない :sob:

base64 -> bytes :ok_woman:
bytes -> utf-8 (str) :dizzy_face:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.7/encodings/utf_8_sig.py", line 23, in decode
    (output, consumed) = codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 12-13: invalid continuation byte

ちなみに `.decode('utf-8', 'ignore') してみるも、ほとんどがぐっちゃぐちゃで読めたものではない...

base64url が曲者だったっぽい。 https://github.com/ploopkazoo/python-base64url/blob/master/base64url.py のコードを一部流用させてもらったら行けそうな気配。

body_data に payload.body.data が入ってる前提

before

            try:
                body_64decoded = base64.b64decode(body_data)
                print(f'payload.body.data(64decoded): {body_64decoded}')
            except:
                print(f'payload.body.data(64decoded): (passed)')

            try:
                body_decoded = bytes(body_64decoded).decode()
                print(f'payload.body.data(decoded): {body_decoded}')
            except:
                print(f'payload.body.data(decoded): (passed)')

after

            try:
                body_64decoded = base64.b64decode(base64urldecode(body_data))
                print(f'payload.body.data(64decoded): {body_64decoded}')
            except:
                print(f'payload.body.data(64decoded): (passed)')

            try:
                body_decoded = bytes(body_64decoded).decode()
                print(f'payload.body.data(decoded): {body_decoded}')
            except:
                print(f'payload.body.data(decoded): (passed)')
