使用CORS但没有任何帮助我

Question

I really researche for hours, but did not find any solution yet. I would like to get some data from a different server via jQuery and ajax. I get this error message in my chrome console:

XMLHttpRequest cannot load https://editeddomain.com//somedata.json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:63342' is therefore not allowed access. The response had HTTP status code 401.

This is my set up:

• PHPStorm 2016.1
• jQuery v3.2.1
• Google Chrome
• Fedora 25

This is what I already tried and I still get the same error:

• <?php header('Access-Control-Allow-Origin: *'); ?>
• Started Chrome with --disable-web-security
• Installed the Chrome Extension Allow-Control-Allow-Origin: *
• Installed the Chrome Extension JetBrains IDE Support and added like JetBrains recommended http://*/*

So none of those helped me and I am still seeing the error message.

PS: This tool is only for me, so that's why it is not and never will be installed on a different webserver than my PHPStorm environment

Answer 1

For chrome, add another parameter in addition to --disable-web-security:

--user-data-dir

This was introduced at a later stage by Google.

Also, for this to work, make sure you close ALL instances of Chrome, and then open the one with the parameters in it. And it will only work with the first tab opened there. It will have a yellow bar stating you're using an insecure tab.
