Gmail api download files

A simple Gmail API client in Python for applications.

Currently Supported Behavior:

• Sending html messages
• Sending messages with attachments
• Sending messages with your Gmail account signature
• Retrieving messages with the full suite of Gmail's search capabilities
• Retrieving messages with attachments, and downloading attachments
• Modifying message labels (includes marking as read/unread, important/not important, starred/unstarred, trash/untrash, inbox/archive)

Getting Started

The only setup required is to download an OAuth Client ID file from Google that will authorize your application.

This can be done at: www.cronistalascolonias.com.ar For those who haven't created a credential for Google's API, after clicking the link above (and logging in to the appropriate account),

1. Select/create the project that this authentication is for (if creating a new project make sure to configure the OAuth consent screen; you only need to set an Application name).

2. Click on the "Dashboard" tab, then "Enable APIs and Services". Search for Gmail and enable.

3. Click on the Credentials tab, then "Create Credentials" > "OAuth client ID".

4. Select what kind of application this is for, and give it a memorable name.

5. Back on the credentials screen, click the download icon next to the credential you just created to download it as a JSON object.

6. Save this file as "client_www.cronistalascolonias.com.ar" and place it in the root directory of your application. (The class takes in an argument for the name of this file if you choose to name it otherwise.)

The first time you create a new instance of the class, a browser window will open, and you'll be asked to give permissions to the application. This will save an access token in a file named "www.cronistalascolonias.com.ar", and only needs to occur once.

You are now good to go!

Note about authentication method: I have opted not to use a username-password authentication (through imap/smtp), since using Google's authorization is both significantly safer and avoids clashing with Google's many security measures.

Installation

Install using (Python3).

pip3 install simplegmail

Usage

Send a simple message:

fromsimplegmailimportGmailgmail=Gmail()# will open a browser window to ask you to log in and authenticateparams={"to":"you@www.cronistalascolonias.com.ar","sender":"me@www.cronistalascolonias.com.ar","subject":"My first email","msg_html":"<h1>Woah, my first email!</h1><br />This is an HTML email.","msg_plain":"Hi\nThis is a plain text email.","signature":True# use my account signature}message=www.cronistalascolonias.com.ar_message(**params)# equivalent to send_message(to="you@www.cronistalascolonias.com.ar", sender=)

Send a message with attachments, cc, bcc fields:

fromsimplegmailimportGmailgmail=Gmail()params={"to":"you@www.cronistalascolonias.com.ar","sender":"me@www.cronistalascolonias.com.ar","cc":["bob@www.cronistalascolonias.com.ar"],"bcc":["marie@www.cronistalascolonias.com.ar","hidden@www.cronistalascolonias.com.ar"],"subject":"My first email","msg_html":"<h1>Woah, my first email!</h1><br />This is an HTML email.","msg_plain":"Hi\nThis is a plain text email.","attachments":["path/to/something/www.cronistalascolonias.com.ar","path/to/www.cronistalascolonias.com.ar","path/to/www.cronistalascolonias.com.ar"],"signature":True# use my account signature}message=www.cronistalascolonias.com.ar_message(**params)# equivalent to send_message(to="you@www.cronistalascolonias.com.ar", sender=)

It couldn't be easier!

Retrieving messages:

fromsimplegmailimportGmailgmail=Gmail()# Unread messages in your inboxmessages=www.cronistalascolonias.com.ar_unread_inbox()# Starred messagesmessages=www.cronistalascolonias.com.ar_starred_messages()# and many more easy to use functions can be found in www.cronistalascolonias.com.ar!# Print them out!formessageinmessages:print("To: "+www.cronistalascolonias.com.arent)print("From: "+www.cronistalascolonias.com.ar)print("Subject: "+www.cronistalascolonias.com.art)print("Date: "+www.cronistalascolonias.com.ar)print("Preview: "+www.cronistalascolonias.com.art)print("Message Body: "+www.cronistalascolonias.com.ar)# or www.cronistalascolonias.com.ar

Marking messages:

fromsimplegmailimportGmailgmail=Gmail()messages=www.cronistalascolonias.com.ar_unread_inbox()message_to_read=messages[0]message_to_www.cronistalascolonias.com.ar_as_read()# Oops, I want to mark as unread nowmessage_to_www.cronistalascolonias.com.ar_as_unread()message_to_star=messages[1]message_to_www.cronistalascolonias.com.ar()message_to_trash=messages[2]message_to_www.cronistalascolonias.com.ar()# and many more functions can be found in www.cronistalascolonias.com.ar!

Changing message labels:

fromsimplegmailimportGmailgmail=Gmail()# Get the label objects for your account. Each label has a specific ID that # you need, not just the name!labels=www.cronistalascolonias.com.ar_labels()# To find a label by the name that you know (just an example):finance_label=list(filter(lambdax:www.cronistalascolonias.com.ar=='Finance',labels))[0]messages=www.cronistalascolonias.com.ar_unread_inbox()# We can add/remove a labelmessage=messages[0]www.cronistalascolonias.com.ar_label(finance_label)# We can "move" a message from one label to www.cronistalascolonias.com.ar_labels(to_add=labels[10],to_remove=finance_label)# check out the code in www.cronistalascolonias.com.ar for more!

Downloading attachments:

fromsimplegmailimportGmailgmail=Gmail()messages=www.cronistalascolonias.com.ar_unread_inbox()message=messages[0]www.cronistalascolonias.com.arments:www.cronistalascolonias.com.arments:print('File: '+www.cronistalascolonias.com.arme)www.cronistalascolonias.com.ar()# downloads and saves each attachment under it's stored# filename. You can download without saving with `www.cronistalascolonias.com.arad()`

Retrieving messages (advanced, with queries!):

www.cronistalascolonias.com.armportconstruct_querygmail=Gmail()# Unread messages in inbox with label "Work"messages=www.cronistalascolonias.com.ar_unread_inbox(label_ids=["Work"])# For even more control use queries:# Messages that are: newer than 2 days old, unread, labeled "Work" or both "Homework" and "CS"query_params={"newer_than":(2,"day"),"unread":True,"labels":[["Work"],["Homework","CS"]]}messages=www.cronistalascolonias.com.ar_messages(query=construct_query(query_params))# We could have also accomplished this with# messages = www.cronistalascolonias.com.ar_unread_messages(query=construct_query(newer_than=(2, "day"), labels=[["Work"], ["Homework", "CS"]]))# There are many, many different ways of achieving the same result with search.

Retrieving messages (more advanced, with more queries!):

www.cronistalascolonias.com.armportconstruct_querygmail=Gmail()# For even more control use queries:# Messages that are either:# newer than 2 days old, unread, labeled "Work" or both "Homework" and "CS"# or# newer than 1 month old, unread, labeled "Top Secret", but not starred.# Construct our two queries separatelyquery_params_1={"newer_than":(2,"day"),"unread":True,"labels":[["Work"],["Homework","CS"]]}query_params_2={"newer_than":(1,"month"),"unread":True,"labels":["Top Secret"],"starred":True,"exclude_starred":True}# construct_query() will create both query strings and "or" them www.cronistalascolonias.com.ares=www.cronistalascolonias.com.ar_messages(query=construct_query(query_params_1,query_params_2))
