This article attempts to simulate the implementation of the Webdriver Java binding directly using Webdriver's Rest API, which facilitates a more in-depth understanding of selenium webdriver and its framework, and is the most basic knowledge in future projects where the framework needs to be modified. , and can even customize their binding in their own way, providing additional functionality.

1. Start Selenium-server-standalone as REST API service

• Start Hub:java-jar selenium-server-standalone-2.53.0.jar-role Hub
• Start Node:java-jar selenium-server-standalone-2.53.0.jar-role node-hub Http://localhost:4444/grid/register-browser "b Rowsername=firefox,firefx_binary=<path-to-firefox-executable>,maxinstances=6,platform=windows "

2. When hub and node are started, they can send a request to the relevant Service API address, in this case the hub and node are started locally

3. REST API refer to the link at the beginning of this article, request the link format Http://localhost:4444/wd/hub + < requested api>

Such as

The POST Http://localhost:4444/wd/hub/session will return the created session information, and subsequent requests will be based on that session.
