Gmail Wrapper

Because scrapping Gmail data doesn't have to be a pain.

Installing

pip install gmail-wrapper

Developing

Create your venv

virtualenv .venv
source .venv/bin/activate

Then you can install the dependencies

pip install -e .

Testing

Simply run

make test

Basic Usage

• Setup the client

from gmail_wrapper import GmailClient

email_account = "john.doe@gmail.com"
credentials_string = "{...}" # You must generate this on your Google account
scopes = [GmailClient.SCOPE_READONLY]
client = GmailClient(email_account, secrets_json_string=credentials_string, scopes=scopes)

• Fetch messages

import sys

query = "filename:pdf label:friends" # Check Gmail query docs: https://support.google.com/mail/answer/7190
messages = client.get_messages(query=query, limit=10)
for message in messages:
    print("-- MESSAGE {} --".format(message.id))
    print("SUBJECT: {}".format(message.subject))
    print("DATE: {}".format(message.date))
    for attachment in message.attachments:
        print("\t-- ATTACHMENT {} --".format(attachment.id))
        print("\t\tFILENAME: {}".format(attachment.filename))
        print("\t\tDECODED SIZE: {}".format(sys.getsizeof(attachment.content)))

• Modify message labels

If a single message:

message_id = "..."
message = client.get_message(message_id)
print(message.labels) # ["foo", "bar"]
message.modify(add_labels=["processed"], remove_labels=["foo"]) # Beware that you'll need proper scopes
print(message.labels) # ["bar", "processed"]

If multiple messages:

message_ids = ["...", "..."]
message = client.modify_multiple_messages(message_ids, ["processed"], remove_labels=["foo"])

• Archive a message

message.archive() # Beware that you'll need proper scopes

• Send message

content = '''
<html>
    <h1>Hey there</h1>
    <p>I am using gmail-wrapper lib!</p>
</html>
'''

message = client.send(
    subject="You will like it",
    html_content=content,
    to="thanos@loadsmart.com",
    cc=["iron.man@loadsmart.com", "spider.man@loadsmart.com"],
    bcc=["wolverine@loadsmart.com"]
) # Beware that you'll need proper scopes
print(message) # Gmail message: ABC123

• Reply message

message_id = "..."
message = client.get_message(message_id)

reply = '''
I am out for vacation, will return <strong>Jan 14</strong>.

If it is really important, you can call me, but think twice.
'''
response = message.reply(reply)

• Handle exceptions

Exceptions are part of every developer day-to-day. You may want to handle exceptions as follows:

from gmail_wrapper.exceptions import (
    MessageNotFoundError,
    AttachmentNotFoundError,
    GmailError,
)

try:
    do_something()
except MessageNotFoundError as e:
    print(f"There is no message! {e}")
except AttachmentNotFoundError as e:
    print(f"There is no attachment! {e}")
except GmailError as e:
    print(f"Google servers are burning! {e}")
