FileChooser对象通过page.on("filechoose")事件监听。

如下代码实现点击百度搜图按钮，上传文件进行搜索。

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False,slow_mo=1000)
    context = browser.new_context()
    page=context.new_page()
    page.goto("https://www.baidu.com/")
    page.locator("span").filter(has_text="按图片搜索").locator("span").first.click()

    # page.locator("input[type=\"file\"]").set_input_files("2.png")

    with page.expect_file_chooser() as fc_info:
        page.locator("input[type=\"file\"]").click()
    file_chooser = fc_info.value
    file_chooser.set_files(r"C:\Users\Administrator\Desktop\2.png")
    page.pause()
    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)
