How to mark messages as read using gmail api as i parse?

问题

In python how do i mark messages as 'read' as i parse it from gmail api ? Also how do i save the values to the database after parsing? This is the code so far to get the content of each message.

from __future__ import print_function

import os
import re
import MySQLdb
from email.utils import parsedate_tz,mktime_tz,formatdate
from requests.adapters import HTTPAdapter

    import argparse
    flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
    flags = None
SCOPES = 'https://www.googleapis.com/auth/gmail.readonly'
CLIENT_SECRET_FILE = 'client_server.json'
APPLICATION_NAME = 'Gmail API Python Quickstart'
def get_credentials():

    home_dir = os.path.expanduser('~')
    credential_dir = os.path.join(home_dir, '.credentials')
    if not os.path.exists(credential_dir):
        os.makedirs(credential_dir)
    credential_path = os.path.join(credential_dir,
                                   'gmail-python-quickstart.json')

    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(flow, store, flags)
        else: # Needed only for compatibility with Python 2.6
            credentials = tools.run(flow, store)
        print('Storing credentials to ' + credential_path)
    return credentials

def main():

    da=date.fromordinal(730920)
    credentials = get_credentials()
    http = credentials.authorize(httplib2.Http())
    service = discovery.build('gmail', 'v1', http=http)
    today=date.today()
    print (today)
    yesterday=today-timedelta(1)
    print (yesterday) 
    response = service.users().messages().list(userId='me',q='in:inbox is:unread newer_than:1d').execute()

     message = service.users().messages().get(userId='me',id=store,format='metadata',metadataHeaders=['from','date']).execute()
     fo.write(message['snippet'].encode('utf-8')+"")
     From=message['payload']['headers'][0]['value']
     fo.write(From+"");

You need to modify the message in a separate request, and remove the UNREAD-label.

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

{
 "removeLabelIds": [
  "UNREAD"
 ]
}

If you're trying to mark the message as read, you will have to do something like:

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

What you can do with the Gmail API depends on what scope you've granted OAuth. Here's what you need to do:

Change SCOPES = 'https://www.googleapis.com/auth/gmail.readonly' to this:

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

Explanation: since marking an email as "unread" is a message modification, you need the 'gmail.modify' scope in order to use this API request. To see the full list of scopes, refer to Choose Auth Scopes.

Delete your token.pickle file and rerun the script. You'll need to do this in order to reauthorize the OAuth app with the new scopes, which will then generate a new token.pickle file.
Here's the code to mark an email as read in Python:

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