✍: FYIcenter.com
You can start a new browser session with ChromeDriver WebDriver server
using the "POST /session" service
as shown in this tutorial.
1. Make sure Python is installed:
C:\fyicenter> python --version Python 3.7.4
2. Make sure Python "requests" module is installed:
C:\fyicenter> pip install requests Collecting requests Collecting idna<2.9,>=2.5 (from requests) Collecting chardet<3.1.0,>=3.0.2 (from requests) Collecting certifi>=2017.4.17 (from requests) Installing collected packages: idna, chardet, certifi, requests Successfully installed certifi-2019.6.16 chardet-3.0.4 idna-2.8 requests-2.22.0
3. Start ChromeDriver WebDriver server with logging turned on listening on port 9515.
C:\fyicenter> \fyicenter\selenium\chromedriver\chromedriver.exe --verbose Starting ChromeDriver 75.0.3770.90 (...-refs/branch-heads/3770@{#1003}) on port 9515
4. Enter the following Python script in a separate window to start a new browser session by sending a "POST /session" request:
C:\fyicenter> type PostSessionChrome.py # PostSessionChrome.py # Copyright (c) FYIcenter.com import requests data = """ { "capabilities": { "alwaysMatch": { "browserName": "chrome", "goog:chromeOptions": { "args": [ ], "extensions": [ ] }, "platformName": "any" }, "firstMatch": [ { } ] }, "desiredCapabilities": { "browserName": "chrome", "goog:chromeOptions": { "args": [ ], "extensions": [ ] }, "platform": "ANY", "version": "" } } """ res = requests.post("http://localhost:9515/session", data) print("Status: " + str(res.status_code)) print("Body: " + str(res.content))
5. Run the Python script:
C:\fyicenter> python PostSessionChrome.py Status: 200 Body: b'{ "value": { "capabilities": { "acceptInsecureCerts": false, "browserName": "chrome", "browserVersion": "75.0.3770.142", "chrome": { "chromedriverVersion": "75.0.3770.90 (...-refs\/branch-heads\/3770@{#1003})", "userDataDir": "C:\\Users\\fyicenter\\AppData\\Local\\Temp\\scoped_dir70244_21653" }, "goog:chromeOptions": { "debuggerAddress": "localhost:63448" }, "networkConnectionEnabled": false, "pageLoadStrategy": "normal", "platformName": "windows nt", "proxy": {}, "setWindowRect": true, "strictFileInteractability": false, "timeouts": { "implicit": 0, "pageLoad": 300000, "script": 30000 }, "unhandledPromptBehavior": "dismiss and notify" }, "sessionId": "d1e9fd4561397db9b4deb2cb5bbd0dbf" } }'
You should see that WebDriver server starts a new session with a new Chrome window started.
