node-remote does not recognize file:// scheme

NWJS Version : 0.41.2 Operating System : macOS 10.15

Expected behavior

node-remote in manifest is said to support URL schemes ‘http’, ‘https’, ‘file’, ‘ftp’ (here: http://docs.nwjs.io/en/latest/References/Manifest Format/#node-remote).

Actual behavior

Setting node-remote: ["file://*"] (or any other file:// URL pattern) results in the following error on application startup:

Failed to load extension from: <--location-->.
Invalid value for 'app.urls[0]': Invalid scheme.

Setting it to ["*://*"] allows the application to start, but has no effect on file:// URIs. This may be related to https://github.com/nwjs/nw.js/issues/6860.

How to reproduce

This is a minimal package.json that reproduces the error:

{
    "name": "node-remote-issue",
    "main": "index.html",
    "node-remote": [
        "file://*"
    ]
}

Run nw in a directory containing this file.

This is fixed in git and will be available in the next nightly build.

I resolved ths probem, like this: 1\set package.json “chromium-args”:“–disable-web-security’”

2\ Use window.postMessage('what your want to send",“*”) instead of javscript call.

That’s all. It works!
