I'm learning gmail api through google colab.
I'm running the quickstart code in colab and my browser is edge.

else:
print('Labels:')
for label in labels:
print(label['name'])
if __name__ == '__main__':

after I click the authoritize steps, it pops out
it can't find the local host.
I have no idea what to do, and this quickstart can run successful in jupyter.

There is a simple way to send e-mail at google colab? with or without using gmail?
i'm using the google colab at opera browser.
Can anyone help me how i can send a simple e-mail at google colab without lowing the gmail security level?

There is something wrong with the way you are loading the run_local_server if you are getting a 404 error.
The code below is my standard QuickStart for People api. I just tested it and it works fine. I am not getting a 404 error.

i'm building python GMAIL API for checking emails for 10 email accounts
but in google documentation not very useful.
this seems only support one account
https://github.com/suleenwong/Gmail-API-Python
If we check the default sample python quickstart This sample was designed to be single user but that can be changed.
The following section creates a token.json file when the user authorizes the application. The file will contain the access token and refresh token for the user who authorized the code.
If the file does not exist then the app will prompt the user to authorize it. If it does then the app will load the credentials from that file and run the code with the authorization of that user.
# The file token.json stores the user's access and refresh tokens, and is
# created automatically when the authorization flow completes for the first
# time.
if os.path.exists('token.json'):
creds = Credentials.from_authorized_user_file('token.json', SCOPES)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
'credentials.json', SCOPES)
creds = flow.run_local_server(port=0)
# Save the credentials for the next run
with open('token.json', 'w') as token:
token.write(creds.to_json())
To add more users you can simply rename that file tokenUserOne.json, tokenUserTwo.json. Then set it up so that you can supply the file name you want your script to run on. You will only need to authorize each user once. As long as you have a token.json file for each user separated, your app can then be started using which ever token file you want, to access each users data.
https://developers.google.com/gmail/api/quickstart/python -this is the proper documentation everything you need is in here
aka (you also need a client_secet.json file but you will have to get yourself for the google cloud dashbord):

I have a problem with my google drive API.
I use this code to connect to my google account and get service :
from google.oauth2.credentials import Credentials
from google.auth.transport.requests import Request
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
def getService():
# If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/drive']
"""Shows basic usage of the Drive v3 API.
Prints the names and ids of the first 10 files the user has access to.
"""
creds = None
# The file token.json stores the user's access and refresh tokens, and is
# created automatically when the authorization flow completes for the first
# time.
if os.path.exists('token.json'):
creds = Credentials.from_authorized_user_file('token.json', SCOPES)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
'code_secret_client_XXX.apps.googleusercontent.com.json',
SCOPES)
creds = flow.run_local_server(port=0)
# Save the credentials for the next run
with open('token.json', 'w') as token:
token.write(creds.to_json())
service = build('drive', 'v3', credentials=creds)
return service
It works perfectly, but when I call 2 times for example :
result1 = GoogleDrive.service.files().list(
pageSize=1000, fields="nextPageToken, files(id, name)").execute()
result2 = GoogleDrive.service.about().get(
fields="storageQuota").execute()
I have this error :
ssl.SSLError: [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:2633)
According to the documentation the Drive API is built on top of Httplib2 which is not thread safe.
I use oauth2client which is deprecated, could that be the problem?
If I add a time.sleep(1) between my requests, it works.
if I remove one of the two requests, it works...
I don't understand how I can achieve that..
Thanks a lot
I think I found a solution :

But the script is generating HttpError 403 error something like
"Request had insufficient authentication scopes.". Details: "Request had insufficient authentication scopes."
How to resolve this issue?
I had the same issue, delete token.pickle from your folder and execute again. it should work
I'm trying to parse each and every mail body from my gmail account using google oauth and gmail api services. As per now I can only get the messages id and thread id, when I open them it doesn't make sense at all.
So the following code I have used that are as below:
from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/gmail.readonly']
def main():
"""Shows basic usage of the Gmail API.
Lists the user's Gmail labels.
"""
creds = None
# The file token.pickle stores the user's access and refresh tokens, and is
# created automatically when the authorization flow completes for the first
# time.
if os.path.exists('token.pickle'):
with open('token.pickle', 'rb') as token:
creds = pickle.load(token)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
'credentials.json', SCOPES)
creds = flow.run_local_server()
# Save the credentials for the next run
with open('token.pickle', 'wb') as token:
pickle.dump(creds, token)
service = build('gmail', 'v1', credentials=creds)
# Call the Gmail API
results = service.users().labels().list(userId='me').execute()
print(service.users().messages().list(userId='me').execute())
print(service.users().messages().get(userId='me', id='16931216e3a05048').execute())
labels = results.get('labels', [])
if not labels:
print('No labels found.')
else:
print('Labels:')
for label in labels:
print(label['name'])
if __name__ == '__main__':
main()
and the output I got is like this for one of the message id using this line print(service.users().messages().get(userId='me', id='16931216e3a05048').execute())
the output is like this:
You forgot to add the format
messages.get
message = service.users().messages().get(userId=user_id, id=msg_id,
format='raw').execute()
print 'Message snippet: %s' % message['snippet']
msg_str = base64.urlsafe_b64decode(message['raw'].encode('ASCII'))
mime_msg = email.message_from_string(msg_str)
