Disable-web-security in Chrome 48+

问题:

I have a problem with the --disable-web-security flag. It is not working in Chrome 48 and Chrome 49 beta on Windows.

I've tried killing all of the instances, reboot and run Chrome with the flag first of all, tried different machines as well. In the beta I can see the warning popup ("You are using unsupported flag.."), but CORS is still being enforced. Public version seems to ignore the flag completely.

There seems to be no news or people reports about that, so it might be a local issue. Will be grateful for help or any related info.

I'm seeing the same thing. A quick google found this question and a bug on the chromium forums. It seems that the --user-data-dir flag is now required. Edit to add user-data-dir guide

回答2:

Mac OS:

open -a Google\ Chrome --args --disable-web-security --user-data-dir=""

UPD: add "" to --user-data-dir because newer chrome versions require it in order to work

The chosen answer is good, but for those who are still struggling with what they are talking about(your first time dealing with this issue), the following worked for me.

I created a new shortcut to Chrome on my desktop, right clicked it, and set the "Target" field to the following,

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="c:/chromedev"

The directory can be anything you want, I decided to make an empty folder called chrome dev in my C: directory. It has nothing to do where chrome is installed on your computer. It's just a fluff type thing.

The version 49.0.2623.75 (64-bit) is not in beta anymore.

The command to fix the CORS issue is google-chrome-stable --disable-web-security --user-data-dir

On OS X, to open a new Chrome window - without having to close the already open windows first - pass in the additional -n flag. Make sure to specify empty string for data-dir (necessary for newer versions of Chrome, like v50 something+).

open -na /Applications/Google\ Chrome.app/ --args --disable-web-security --user-data-dir=""

I found that using Chrome 60+ on Mac OS X Sierra, the above command no longer worked, but a slight modification does:

open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir="/tmp/chrome_dev_sess_1" --disable-web-security

The data directory path is important. Even if you're standing in your home directory when issuing the command, you can't simply refer to a local directory. It needs to be an absolute path.

For Mac, using Safari is a good alternate option for local development purpose and the feature is built into the browser (so no need to add browser extension or launch Chrome using bash command like [open -a Google\ Chrome --args --disable-web-security --user-data-dir=""].

To disable cross origin restriction using Safari (v11+): From menu click “Develop > Disable Cross Origin Restriction”.

This does not require relaunching the browser and since its a toggle you can easily switch to secure mode.
