Reason: CORS header 'Access-Control-Allow-Origin' does not match 'xyz'

What went wrong?

Simply put, the origin making the request does not match any of the origins permitted by the Access-Control-Allow-Origin header.

This error can also occur if the response includes more than one Access-Control-Allow-Origin header.

If the service your code is accessing using a CORS request is under your control, make sure that it's configured to include your origin in its Access-Control-Allow-Origin header, and that only one such header is included in responses. The header itself accepts a comma-delineated list of origins, so adding a new origin is not difficult.

For example, in Apache, add a line such as the following to the server's configuration (within the appropriate <Directory> , <Location> , <Files> ，或 <VirtualHost> section). The configuration is typically found in a .conf file ( httpd.conf and apache.conf are common names for these), or in an .htaccess 文件。

Header set Access-Control-Allow-Origin 'origin-list'

For Nginx, the command to set up this header is:

add_header 'Access-Control-Allow-Origin' 'origin-list'
