You do not need to save the image to a file at all (cmp. screenshot documentation), but instead can simply store it in a variable, like img = page.screenshot()
. You can then pass that variable to your REST request. I use the requests
module in the example below, the POST request is simplified and may require some additional parameters (depending on your API) or for instance different URLs for the different browser types:
from playwright import sync_playwright
import requests
with sync_playwright() as p:
for browser_type in [p.chromium, p.firefox, p.webkit]:
browser = browser_type.launch()
page = browser.newPage()
page.goto('https://scrapingant.com/')
# save screenshot to var
img = page.screenshot()
# pass var directly to your request
files = {'image': img, 'content-type': 'image/png'}
requests.post('http://yourresturl.com', files=files)
browser.close()
If you really wanted to save the image to a temporary file for some reason (which, as I understand your use case, is not really necessary), you could e.g. use the tempfile
module and create a named temporary file (cmp. How to use tempfile.NamedTemporaryFile()?):
from playwright import sync_playwright
import tempfile
import requests
tf = tempfile.NamedTemporaryFile(suffix='.png')
with sync_playwright() as p:
for browser_type in [p.chromium, p.firefox, p.webkit]:
browser = browser_type.launch()
page = browser.newPage()
page.goto('https://scrapingant.com/')
# save screenshot to temporary file
page.screenshot(path=tf.name)
# send request loading temporary file
requests.post('http://myresturl.com', {'media': open(tf.name, 'rb')})
browser.close()
# close temporary file
tf.close()

With the rapidly evolving technology due to its ever-increasing demand in today’s world, Digital Security has become a major concern for the Software Industry. There are various ways through which Digital Security can be achieved, Captcha being one of them.Captcha is easy for humans to solve but hard for “bots” and other malicious software to figure out. However, Captcha has always been tricky for the testers to automate, as many of them don’t know how to handle captcha in Selenium or using any other test automation framework.
Playwright is a framework that I’ve always heard great things about but never had a chance to pick up until earlier this year. And since then, it’s become one of my favorite test automation frameworks to use when building a new automation project. It’s easy to set up, feature-packed, and one of the fastest, most reliable frameworks I’ve worked with.
Open MCT is a next-generation mission control framework for data visualization on desktop and mobile devices. It was created at NASA’s Ames Research Center, and NASA uses it to analyze spacecraft mission data.
Selenium is still the most influential and well-developed framework for web automation testing. Being one of the best automation frameworks with constantly evolving features, it is poised to lead the industry in all aspects as compared to other trending frameworks like Cypress, Puppeteer, PlayWright, etc. Furthermore, using Selenium gives you the flexibility to use different programming languages like C#, Ruby, Perl, Java, Python, etc., and also accommodate different operating systems and web browsers for Selenium automation testing.
LambdaTest’s Playwright tutorial will give you a broader idea about the Playwright automation framework, its unique features, and use cases with examples to exceed your understanding of Playwright testing. This tutorial will give A to Z guidance, from installing the Playwright framework to some best practices and advanced concepts.
