尝试将变量传递给 Puppeteer 中的参数

Question

如何在 Puppeteer 中将变量传递给参数。我的最终目标是为 pdf 提供多个名称（90 多个名称），而无需键入每个文件名

var name = example1

await page.pdf({
        path: '/name/.pdf',
        printBackground: true,
      });

Answer 1

希望这有帮助，（您也可以使用字符串连接）

const names = ['example1', 'example2', 'example3'];
for (const name of names) {
    await page.pdf({
        path: `/${name}.pdf`,
        printBackground: true,
    });
}

假设您想要打开每个 URL，然后将网页另存为 PDF 文件。您可以根据 URL 或网页标题确定文件名/路径，然后使用 @digbijay-gautam 方法保存 pdf 文件。以此页面为例，您可以使用以下文件名/路径：

{
  "url": "https://stackoverflow.com/questions/77744840/trying-to-pass-a-variable-to-a-parameter-in-puppeteer",
  "basename": "trying-to-pass-a-variable-to-a-parameter-in-puppeteer.pdf",
  "hostname_hashcode__MD5": "stackoverflow.com_981ce9411a44018e69819ca11425396b.pdf",
