* Config Middleware
|
|
* -------------------------------------------------------------
|
|
* Checks the specified configuration key (and optionally the value).
|
|
* If the configuration matches the required value, the request can
|
|
* proceed. Otherwise, a 404 will be returned.
|
|
*
|
|
* To use, add the call to your route's middleware:
|
|
*
|
|
* ['middleware::util:Config', {key: 'server.ssl.test', value: true}],
|
|
*
|
|
* In this case, the request would be allowed to proceed in the case:
|
|
* services.configs.get('server.ssl.test') === true
|
|
*
|
|
* The 'value' attribute is optional. If none is provided, the request
|
|
* can proceed if the config value is truthy.
