如何在解析時使用 gmail api 將郵件標記為已讀？

Question

在 python 中，我如何在從 gmail api 解析消息時將消息標記為“已讀”？ 另外我如何在解析后將值保存到數據庫中？ 到目前為止，這是獲取每條消息內容的代碼。

    store = oauth2client.file.Storage(credential_path)
    credentials = store.get()
    if not credentials or credentials.invalid:
        flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
        flow.user_agent = APPLICATION_NAME
        if flags:

            credentials = tools.run(flow, store)
        print('Storing credentials to ' + credential_path)
    return credentials

需要幫助請！

Answer 1

您需要在單獨的請求中修改消息，並刪除UNREAD標簽。

POST https://www.googleapis.com/gmail/v1/users/me/messages/1533cb4d7dac1633/modify?access_token={ACCESS_TOKEN}

{
 "removeLabelIds": [
  "UNREAD"
 ]
}

Answer 2

如果您嘗試將消息標記為已讀，則必須執行以下操作：

gmail_service
       .users()
       .messages()
       .modify(userId='me', id=message_id, body={'removeLabelIds': ['UNREAD']})
       .execute()

Answer 3

您可以使用 Gmail API 做什么取決於您授予 OAuth 的范圍。 您需要執行以下操作：

1. 將SCOPES = 'https://www.googleapis.com/auth/gmail.readonly'更改為：

SCOPES = [
    'https://www.googleapis.com/auth/gmail.readonly',
    'https://www.googleapis.com/auth/gmail.modify'
]

說明：由於將電子郵件標記為“未讀”是一種消息修改，因此您需要“gmail.modify”范圍才能使用此 API 請求。 要查看范圍的完整列表，請參閱選擇身份驗證范圍。

2. 刪除您的token.pickle文件並重新運行腳本。 您需要執行此操作才能使用新范圍重新授權 OAuth 應用程序，然后將生成新的token.pickle文件。

3. 這是在 Python 中將電子郵件標記為已讀的代碼：

service.users().messages().modify(userId='me', id=message['id'], body={
    'removeLabelIds': ['UNREAD']
}).execute()
