找不到文件的Pupeteer抛出错误

Question

I have the following code, for which I am converting an html page into PDF. I see the file is present in the location, but an error occurs when it run.

    const puppeteer = require('puppeteer');

    var pdfPath = path.join("C:/Users/Testing");

    (async () => {
      const browser = await puppeteer.launch();
      const page = await browser.newPage();
      var contentHtml = fs.readFileSync('file:///C:/Users/Mytesting/test.html', { waitUntil: "networkidle2" });
      await page. setContent(contentHtml); 
      await page.pdf({path: pdfPath , format : 'A4'});
      await browser.close();
    })();

I can open the html file in browser and it renders properly.

Error:

 { Error: ENOENT: no such file or directory, open 'file:///C:/Users/Mytesting/test.html' at Object.openSync (fs.js:443:3) at Object.readFileSync (fs.js:343:35) at C:\Users\shiva.nara\NodeProjects\KioskApp\controllers\node.controller.schedulesearch.js:768:28 at process._tickCallback (internal/process/next_tick.js:68:7) errno: -4058, syscall: 'open', code: 'ENOENT', path: 'file:///C:/Users/Mytesting/test.html' }

Answer 1

Your path pattern for an absolute path is wrong. You can omit file:/// . Use instead the following:

fs.readFileSync('C:/Users/Mytesting/test.html');

Also don't use { waitUntil: "networkidle2" } , as it is not a valid option. See the fs docs .
