Library and middleware enabling cross-origin resource sharing for your http-{foundation,kernel} using application. It attempts to implement the W3C Recommendation for cross-origin resource sharing.
Build status: 
Require asm89/stack-cors using composer.
This package can be used as a library or as stack middleware.
| Option | Description | Default value |
|---|---|---|
allowedMethods | Matches the request method. | [] |
allowedOrigins | Matches the request origin. | [] |
allowedOriginsPatterns | Matches the request origin with preg_match. | [] |
allowedHeaders | Sets the Access-Control-Allow-Headers response header. | [] |
exposedHeaders | Sets the Access-Control-Expose-Headers response header. | false |
maxAge | Sets the Access-Control-Max-Age response header. Set to null to omit the header/use browser default. | 0 |
supportsCredentials | Sets the Access-Control-Allow-Credentials header. | false |
The allowedMethods and allowedHeaders options are case-insensitive.
You don't need to provide both allowedOrigins and allowedOriginsPatterns. If one of the strings passed matches, it is considered a valid origin.
If ['*'] is provided to allowedMethods, allowedOrigins or allowedHeaders all methods / origins / headers are allowed.
If supportsCredentials is true, you must explicitly set allowedHeaders for any headers which are not CORS safelisted.
