How to pass all headers from playwright python?

Question

Currently, I can send the user-agent from playwright as well the viewport sizes. But i want to send all the headers informations like accept, accept_encoding, accept_language,referer, cookies,etc . I looked about setExtraHTTPHeaders() too. Is there any way to send them in playwright python.

with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)
    context = browser.new_context(
                user_agent=agent #agent declared above,
            )
    page = context.new_page()
    response = page.goto("https://www.somewebsite.com/")

    #Doing some work in the website
    page.locator('#some_id').fill("some_text")
    page.press('#another_id', "Enter")

    page.route("**/*", intercept_route)

Answer 1

The answer was found when i looked what is inside dir(context) . In python, we can use context.set_extra_http_headers(headers) to send extra headers informations like accept, accept-encoding, referrer, accept-language,etc

Answer 2

user-agent , prefers-colors-scheme , accept-language , and cookies can be set with the browser's new_context 's arguments user_agent , color_scheme , locale , and storage_state , respectively. referer can be set with page.goto 's argument referer . For other less popular headers that's not mentioned in the documentation , they can be set with new_context 's argument extra_http_headers . The code can look something similar to

context = browser.new_context(
            user_agent=agent,
            color_scheme=r"light",
            locale=r"en-US,en;q=0.9",
            storage_state={cookies: [{}],
            extra_http_headers={}
        )
page = context.new_page()
response = page.goto(r"https://www.somewebsite.com/",
                     referer=r"https://google.com"
        )

The same can apply for browser.new_page() . To better see what headers your browser sends you can go to similar sites like this one . Hope that helps, good luck.
