剧作家不会导航到 URL (Python)答案

【问题标题】：Playwright won't navigate to URL (Python)剧作家不会导航到 URL (Python)

【问题描述】：

下面的代码导致第 22 行出现超时错误。它挂起的页面加载正常。我不认为“点击”是出于任何原因。我检查了这个问题，但没有帮助：Navigating to \"url\", waiting until \"load\" - Python Playwright Issue

我的目标是下载 csv 文件。我不能直接链接到它，因为它依赖于用户会话期间输入的信息。

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context()

    # Open new page
    page = context.new_page()

    # Go to https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx?T=637994490317517425
    page.goto(\"https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx?T=637994490317517425\")

    # Click input[name=\"ctl00\\$ContentPlaceHolder1\\$txtCmteID\"]
    page.locator(\"input[name=\\\"ctl00\\\\$ContentPlaceHolder1\\\\$txtCmteID\\\"]\").click()

    # Fill input[name=\"ctl00\\$ContentPlaceHolder1\\$txtCmteID\"]
    page.locator(\"input[name=\\\"ctl00\\\\$ContentPlaceHolder1\\\\$txtCmteID\\\"]\").fill(\"34589\")
    
    # Click input:has-text(\"Search\")
    page.locator(\"input:has-text(\\\"Search\\\")\").click()
    page.wait_for_url(\"https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx?txtCmteID=%2fVrwBYk8TlTSLyRmy7TWmQ%3d%3d&ddlVendorState=Ry707kcsXsM%3d&ddlContributionType=wOGh3QTPfKqV2YWjeRmjTeStk426RfVK&ddlState=Ry707kcsXsM%3d&ddlFiledDateTime=Ry707kcsXsM%3d&ddlFiledDateTimeThru=Ry707kcsXsM%3d&T=637999702238350506\")

    # Click text=Download This List
    page.locator(\"text=Download This List\").click()
    page.wait_for_url(\"https://www.elections.il.gov/CampaignDisclosure/DownloadList.aspx?T=637999702324593366\")

    # Click text=CSV File
    with page.expect_download() as download_info:
        page.locator(\"text=CSV File\").click()
    download = download_info.value

    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)

【解决方案1】：

我猜你可能正在使用 codegen。

如我所见，该页面对于网址有点奇怪。

无论如何，我修复了你的代码：

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context()

    # Open new page
    page = context.new_page()

    # Go to https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx?T=637994490317517425
    page.goto(
        "https://www.elections.il.gov/CampaignDisclosure/ContributionSearchByCommittees.aspx")

    # Fill input[name="ctl00\$ContentPlaceHolder1\$txtCmteID"]
    page.locator("input[name=\"ctl00\\$ContentPlaceHolder1\\$txtCmteID\"]").fill("34589")

    page.locator("input:has-text(\"Search\")").click()

    page.locator("text=Download This List").click()

    # Click text=CSV File
    with page.expect_download() as download_info:
        page.locator("text=CSV File").click()
    download = download_info.value
    download.save_as(download.suggested_filename)


    # ---------------------
    context.close()
    browser.close()


with sync_playwright() as playwright:
    run(playwright)
