allow_origins

allow_origins determines the value of the Access-Control-Allow-Origin response header. This header defines a list of origins that may access the resource.

The wildcard characters * and ? are supported and are converted to regex fragments .* and . accordingly.

allow_origins

• is optional

• cannot be null

allow_origins Type

string[]

allow_origins Default Value

The default value is:

[
  "http://localhost:8888"
]

unsafe_wildcard_origin_allowed

unsafe_wildcard_origin_allowed allows a wildcard * origin to be used with AllowCredentials flag. In that case we consider any origin allowed and send it back to the client in an Access-Control-Allow-Origin header.

This is INSECURE and potentially leads to cross-origin attacks. See also https://github.com/labstack/echo/issues/2400 for discussion on the subject.

Optional. Default value is false.

unsafe_wildcard_origin_allowed

• is optional

• cannot be null

unsafe_wildcard_origin_allowed Type

boolean (unsafe_wildcard_origin_allowed)
