CorsRule Class

CORS is an HTTP feature that enables a web application running under one domain to access resources in another domain. Web browsers implement a security restriction known as same-origin policy that prevents a web page from calling APIs in a different domain; CORS provides a secure way to allow one domain (the origin domain) to call APIs in another domain.

CorsRule

Constructor

CorsRule(allowed_origins, allowed_methods, **kwargs)

Parameters

allowed_origins
list(str)
Required

A list of origin domains that will be allowed via CORS, or "*" to allow all domains. The list of must contain at least one entry. Limited to 64 origin domains. Each allowed origin can have up to 256 characters.

allowed_methods
list(str)
Required

A list of HTTP methods that are allowed to be executed by the origin. The list of must contain at least one entry. For Azure Storage, permitted methods are DELETE, GET, HEAD, MERGE, POST, OPTIONS or PUT.

Keyword-Only Parameters

allowed_headers
list(str)

Defaults to an empty list. A list of headers allowed to be part of the cross-origin request. Limited to 64 defined headers and 2 prefixed headers. Each header can be up to 256 characters.

exposed_headers
list(str)

Defaults to an empty list. A list of response headers to expose to CORS clients. Limited to 64 defined headers and two prefixed headers. Each header can be up to 256 characters.

max_age_in_seconds
int

The number of seconds that the client/browser should cache a preflight response.

Methods

as_dict

Return a dict that can be serialized using json.dump.

Advanced usage might optionally use a callback as parameter:

Key is the attribute name used in Python. Attr_desc is a dict of metadata. Currently contains 'type' with the msrest type and 'key' with the RestAPI encoded key. Value is the current value in this object.

The string returned will be used to serialize the key. If the return type is a list, this is considered hierarchical result dict.

See the three examples in this file:

  • attribute_transformer

  • full_restapi_key_transformer

  • last_restapi_key_transformer

If you want XML serialization, you can pass the kwargs is_xml=True.

deserialize

Parse a str using the RestAPI syntax and return a model.

enable_additional_properties_sending
from_dict

Parse a dict using given key extractor return a model.

By default consider key extractors (rest_key_case_insensitive_extractor, attribute_key_case_insensitive_extractor and last_rest_key_case_insensitive_extractor)

is_xml_model
serialize

Return the JSON that would be sent to azure from this model.

This is an alias to as_dict(full_restapi_key_transformer, keep_readonly=False).

If you want XML serialization, you can pass the kwargs is_xml=True.
