pybas-automation 0.1.16

A Python library for automating BrowserAutomationStudio (BAS) using headless Chromium browsers and Windows GUI program.

py-bas-automation

Note: This library is currently in active development, and its API may undergo changes without notice at any time.

Note: This project originally started as a working proof of concept and does not aim to offer extensive support or documentation. It serves as a fundamental demonstration of the concept and should be considered a foundation for further development or experimentation.

Description

This library enables you to work with BAS (BrowserAutomationStudio) using headless Chromium browsers and a customizable Windows GUI program, while controlling it with Python ❤️.

Key Features

• BrowserAutomationStudio Integration: Run BAS seamlessly with headless browsers while enjoying the convenience of a user-friendly and customizable Windows GUI program through BrowserAutomationStudio.
• Unique Fingerprint Feature: The application includes a unique feature that assigns a fingerprint to each browser instance using FingerprintSwitcher. Please be aware that this is paid service.
• Proxy Support: The application supports proxy providers such as Brightdata. Please note that this is a paid service.
• Executing Browser Automation Studio (BAS) Actions from Python: Implement BAS actions from Python using the un-documented API. This includes actions such as retrieving page source, emulating mouse movements, etc. (Note: Not all functions are currently supported).
• Playwright Control: The application leverages Playwright to efficiently manage and control BAS.

Understanding the Workflow

The functioning of BAS (Browser Automation Studio) involves the following steps:

1. Initial Execution: Upon initiation, BAS runs cmd_initial.py. This script is responsible for creating tasks and storing them on the disk for later use.
2. Data Acquisition and Browser Configuration: BAS then retrieves the necessary data, configures, and launches browser instances based on the tasks provided earlier.
3. Task Execution: Following the browser setup, BAS executes cmd_worker.py using the task_id and remote-debugging-port number as command-line parameters.
4. Task Handling: cmd_worker.py obtains both the ws_endpoint and remote-debugging-port from the command line. It then manages complex tasks using Playwright. These tasks can range from opening a webpage to filling out forms or even taking screenshots.
5. Task Completion: Once the tasks have been completed, BAS terminates the browser instances and exits.

The result of running cmd_worker.py is as follows:

{
  "tasks_file": "C:\\Users\\Administrator\\AppData\\Local\\PyBASProfilesTasks\\tasks.json"
}

This is an example of the created tasks_file:

• Start the Program: Once all variables have been set, click the "OK" button to initiate the program.

Advanced Usage

This guide introduces a Python script that integrates the Browser Automation Studio (BAS) with py-bas-automation. The purpose is to handle the creation of browser profiles through FingerprintSwitcher and manage tasks related to these profiles.

Initial script: cmd_initial.py

Description:

This script facilitates the integration between BAS (Browser Automation Studio) and py-bas-automation. It manages the creation of browser profiles using FingerprintSwitcher and generates tasks associated with these profiles.

Overview:

• Initialization: Import essential modules and configure logging.
• Browser Profiles: Utilize FingerprintSwitcher's fingerprint key to generate or manage browser profiles.
• Proxy Support: Configure proxy settings for each browser profile in full-automatic mode by handling proxy providers. Note: at the moment only Brightdata is supported.
• Tasks Generation: Generate an associated task for each browser profile and store it.

Worker script: cmd_worker.py

Description:

This script demonstrates how to execute tasks using the Playwright Python library in conjunction with the pybas_automation package. The primary goal is to fetch task data, connect to an existing browser instance using Playwright, and perform actions on a webpage.

Overview:

• Initialization: Import necessary libraries and set up our task id and debugging port.
• Task Storage: Fetch a specific task from our task storage.
• Remote Browser Connection: Use the remote debugging port to get a WebSocket endpoint, which allows us to connect to an existing browser instance.
• Executing Browser Automation Studio (BAS) Actions from Python: Implement BAS actions from Python using the un-documented API. This includes actions such as retrieving page source, emulating mouse movements, etc. (Note: Not all functions are currently supported).

Planned Improvements:

• Add Proxy support.
• Develop end-to-end tests to thoroughly assess the entire workflow.
• Include build scripts for converting Python files to executable format.
• Expand the repository with more illustrative examples.
