page._client.send('Page.setDownloadBehavior', {behavior: 'allow', downloadPath: './tmp/order'}) causing error

[emclab]

I can download the file to the default subdir which is the download by.

await page.goto('https://www.mysite-com/admin/order?_export_=page%3A1');

However when I specified the download subdir with the following code, the file is still downloaded to the default subdir and with error:

await page._client.send('Page.setDownloadBehavior', {behavior: 'allow', downloadPath: './tmp/order'});

The error is:

Error: net::ERR_ABORTED at https://www.mysite-com/admin/order?_export_=page%3A1
<     at navigate (C:\code\js\wbot\node_modules\puppeteer\lib\FrameManager.js:103:37)
<     at <anonymous>
<     at process._tickCallback (internal/process/next_tick.js:189:7)

Puppeteer is 1.9.0. Is it bug?

@emclab two things here:

• the page.setDownloadBehavior is an experimental DevTools Protocol method; it's not well supported.
• the error you get is the default error Chrome Headless returns when you it's navigated to a downloadable resource; we'll straighten this up as part of Question: How do I get puppeteer to download a file? #299.

We'll move to the proper downloads using response interception once #3471 is fixed; please follow #299 for the updates.

Sorry for the inconvenience!

You might try using an absolute path instead of a relative path.

Also, I am running on Windows from a MinGW64 bash command line, but because the path was going to be passed to an instance of Chrome for Windows, I took care to pass an absolute path that looked right for Windows (e.g. "C:\dev\downloads" or whatever).

(Using process.cwd() along with the "path" npm module took care of the details for me.)
let dir = path.join(process.cwd(), "path", "to", "download", "dir");

If there is error on file which you want to download then try this one:

const myDownloadPath = path.resolve(${Directory Where you want to download})
mkdirp(myDownloadPath)
await page._client.send('Page.setDownloadBehavior', {behavior: 'allow', downloadPath: myDownloadPath });

imported:
const mkdirp = require('mkdirp')
const path = require('path')
