Ng2-pdf-viewer: Cannot Open Local File pdf in Ionic 2

[tunathoni]

Hello,

Sorry i want to ask about my issue, i already run with ionic serve and i try to open local pdf file, it can work properly, but after i try to check in www/ folder especially on index.html, just clicked it once, show in browser, but file is not loaded and show an error like this :

Fetch API cannot load file:///Users/toni/Documents/myApp/www/assets/files/test.pdf. URL scheme must be "http" or "https" for CORS request.

So can you help me to solve this issue ? thanks.

The problem with this is the version of PDFJS-dist that is being used. NPM seems to ignore the pdfjs-dist version in package.json and installs version 1.9.

A quick work around:
npm install [email protected] and check your __package.json__ for version _1.6.329_.

See method onFileSelected() - this is how you can load local pdfs

Im getting the same error.
I generate a pdf file and write it to the device dataDirectory , and get the same error trying to set the pdf Source. downgrading pdfjs-dist didnt help as well.

Hi

Remove the NPM package lock, node_modules and run npm install [email protected]. Hopefully that helps.

Is there a solution for this issue ?
Im using ng2-pdf-viewer v5.0.1 and still getting this error:

"Fetch API cannot load file:///data/user/0/MY_APP/files/MY_FILE.pdf. URL scheme "file" is not supported.

My use case is try to view previously 'downloaded' pdfs on a ionic3 app
Tried other libs like pdfjs and no luck.

Any help would be appreciated
Thanks

Hi, How to resolve the problem ?
I get this message :
polyfills-es2015.js:5958 Access to XMLHttpRequest at 'file:///data/user/0/io.ionic.starter/www/doc/13.pdf' from origin 'http://localhost' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, https."``

This work with the file directly in asset folder and with the next url :
http://localhost:8000/assets/000000221394393_61908343.pdf
But I need to download the file and I can not download it in asset directory.

If your having issues it's because of a the new versions of PDFjs library supplied by Mozilla.

Try working with version 1.0.2: npm i [email protected] --save

Hopefully this will help.
