HTML files: getting around CORS (cross-origin)

[indr]

@Xyless

… which is common for accessing local files.

Yes, if your webpage is opened via the file:// protocol, any request is cross-origin.

@jyeomans

for testing i am using a local json file.

If you really need to load JSON files over the file:// protocol, you have three options:

• Disable the browser setting for CORS protection. For example for Firefox this is: security.fileuri.strict_origin_policy in about:config, which I obviously don’t recommend, or
• Load your JSON files via JSONP, or
• Start a local web server with Python or Node.js to server your files over http://localhost thus not doing cross-origin requests.
