How do I enable Xmlhttprequest in Chrome?

How do I fix cross origin requests are only supported for protocol schemes Chrome Chrome extension https?

Just change the url to http://localhost instead of localhost . If you open the html file from local, you should create a local server to serve that html file, the simplest way is using Web Server for Chrome . That will fix the issue.


Using --disable-web-security switch is quite dangerous! Why disable security at all while you can just allow XMLHttpRequest to access files from other files using --allow-file-access-from-files switch?

Before using these commands be sure to end all running instances of Chrome.

On Windows:

chrome.exe --allow-file-access-from-files

On Mac:

open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files

startup chrome with --disable-web-security

On Windows:

chrome.exe --disable-web-security

On Mac:

open /Applications/Google\ Chrome.app/ --args --disable-web-security

This will allow for cross-domain requests.
I'm not aware of if this also works for local files, but let us know !

And mention, this does exactly what you expect, it disables the web security, so be careful with it.


Mac version. From terminal run:

open /Applications/Google\ Chrome.app/ --args --allow-file-access-from-files

On Ubuntu:

chromium-browser --disable-web-security
