剧作家-页脚模板解析问题

Playwright(Python)将页面另存为PDF功能在页眉或页脚中没有自定义时工作良好。然而,当我尝试引入自定义页脚时,这些值似乎没有得到适当的注入。

示例代码:

from playwright.sync_api import sync_playwright

def generate_pdf_with_page_numbers():
    with sync_playwright() as p:
        browser = p.chromium.launch()
        context = browser.new_context()
        page = context.new_page()

        # Navigate to the desired page
        page.goto('https://example.com')

        # Generate PDF with page numbers in the footer
        pdf = page.pdf(
            path="output.pdf",
            format="A4",
            display_header_footer=True,
            footer_template="""
                <div style="width: 100%; text-align: center; font-size: 10px;">
                    Page {{pageNumber}} of {{totalPages}}
                </div>
            """,
            margin={"top": "40px", "bottom": "40px"}
        )

        browser.close()

# Run the function to generate the PDF
generate_pdf_with_page_numbers()

我原本预计:

Page 1 of 1

但实际上我得到:

Page {{pageNumber}} of {{totalPages}}

你看到这段代码有什么问题吗?

从剧作家文档中, header_template (其格式与 footer_template )提供了许多神奇的类名,您可以使用它们将某些数据注入页面:

from playwright.sync_api import sync_playwright # 1.44.0


def generate_pdf_with_page_numbers():
    with sync_playwright() as p:
        browser = p.chromium.launch()
        context = browser.new_context()
        page = context.new_page()
        page.goto("https://example.com")
        pdf = page.pdf(
            path="output.pdf",
            format="A4",
            display_header_footer=True,
            footer_template="""
                <div style="width: 100%; text-align: center; font-size: 10px;">
                    Page <span class="pageNumber"></span> of
                    <span class="totalPages"></span>
                    <div class="title"></div>
                    <div class="url"></div>
                    <div class="date"></div>
                </div>
            """,
            margin={"top": "40px", "bottom": "40px"}
        )
        browser.close()


if __name__ == "__main__":
    generate_pdf_with_page_numbers()

运行代码,打开output.pdf,观察注入页脚的标题、日期、URL和页面。
