The arguments are identical to :py:func:`cross_origin`, with the addition of a `resources` parameter. The resources parameter defines a series of regular expressions for resource paths to match and optionally, the associated options to be applied to the particular resource. These options are identical to the arguments to :py:func:`cross_origin`. The settings for CORS are determined in the following order 1. Resource level settings (e.g when passed as a dictionary) 2. Keyword argument settings 3. App level configuration settings (e.g. CORS_*) 4. Default settings Note: as it is possible for multiple regular expressions to match a resource path, the regular expressions are first sorted by length, from longest to shortest, in order to attempt to match the most specific regular expression. This allows the definition of a number of specific resource options, with a wildcard fallback for all other resources. :param resources: The series of regular expression and (optionally) associated CORS options to be applied to the given resource path. If the argument is a dictionary, it's keys must be regular expressions, and the values must be a dictionary of kwargs, identical to the kwargs of this function. If the argument is a list, it is expected to be a list of regular expressions, for which the app-wide configured options are applied. If the argument is a string, it is expected to be a regular expression for which the app-wide configured options are applied. Default : Match all and apply app-level configuration :type resources: dict, iterable or string :param origins: The origin, or list of origins to allow requests from. The origin(s) may be regular expressions, case-sensitive strings, or else an asterisk Default : '*' :type origins: list, string or regex :param methods: The method or list of methods which the allowed origins are allowed to access for non-simple requests. Default : [GET, HEAD, POST, OPTIONS, PUT, PATCH, DELETE] :type methods: list or string :param expose_headers: The header or list which are safe to expose to the API of a CORS API specification. Default : None :type expose_headers: list or string :param allow_headers: The header or list of header field names which can be used when this resource is accessed by allowed origins. The header(s) may be regular expressions, case-sensitive strings, or else an asterisk. Default : '*', allow all headers :type allow_headers: list, string or regex :param supports_credentials: Allows users to make authenticated requests. If true, injects the `Access-Control-Allow-Credentials` header in responses. This allows cookies and credentials to be submitted across domains. :note: This option cannot be used in conjunction with a '*' origin Default : False :type supports_credentials: bool :param max_age: The maximum time for which this CORS request maybe cached. This value is set as the `Access-Control-Max-Age` header. Default : None :type max_age: timedelta, integer, string or None :param send_wildcard: If True, and the origins parameter is `*`, a wildcard `Access-Control-Allow-Origin` header is sent, rather than the request's `Origin` header. Default : False :type send_wildcard: bool :param vary_header: If True, the header Vary: Origin will be returned as per the W3 implementation guidelines. Setting this header when the `Access-Control-Allow-Origin` is dynamically generated (e.g. when there is more than one allowed origin, and an Origin than '*' is returned) informs CDNs and other caches that the CORS headers are dynamic, and cannot be cached. If False, the Vary header will never be injected or altered. Default : True :type vary_header: bool Nc 8||_||j|fi|dSdSN)_optionsinit_app)selfappkwargss N/var/www/AppWebDeiv/myenv/lib/python3.11/site-packages/flask_cors/extension.py__init__z CORS.__init__s5 ?
