尝试将大发票转换为 PDF 时出现“超时错误:WAITING Page.printToPDF 失败”:

如何增加超时时间？

Answer 1

在 puppeteer/lib/cjs/puppeteer/common/Page.js 的 createPDFStream 方法中，超时作为一个选项出现:

2007         const { scale = 1, displayHeaderFooter = false, headerTemplate = '', footerTemplate = '', printBackground = false, landscapdscape = false, pageRanges = '', preferCSSPageSize = false, margin = {}, omitBackground = false, timeout = 30000, } = options;
[...]
2045         const result = await helper_js_1.helper.waitWithTimeout(printCommandPromise, 'Page.printToPDF', timeout);

所以尽管 timeout 不是 https://github.com/puppeteer/puppeteer/blob/main/docs/api.md#pagepdfoptions 的记录选项, 它似乎确实是 .pdf 方法的一个选项。
