/**
|
||
|
|
* Representation of an incoming, server-side HTTP request.
|
||
|
|
*
|
||
|
|
* Per the HTTP specification, this interface includes properties for
|
||
|
|
* each of the following:
|
||
|
|
*
|
||
|
|
* - Protocol version
|
||
|
|
* - HTTP method
|
||
|
|
* - URI
|
||
|
|
* - Headers
|
||
|
|
* - Message body
|
||
|
|
*
|
||
|
|
* Additionally, it encapsulates all data as it has arrived to the
|
||
|
|
* application from the CGI and/or PHP environment, including:
|
||
|
|
*
|
||
|
|
* - The values represented in $_SERVER.
|
||
|
|
* - Any cookies provided (generally via $_COOKIE)
|
||
|
|
* - Query string arguments (generally via $_GET, or as parsed via parse_str())
|
||
|
|
* - Upload files, if any (as represented by $_FILES)
|
||
|
|
* - Deserialized body parameters (generally from $_POST)
|
||
|
|
*
|
||
|
|
* $_SERVER values MUST be treated as immutable, as they represent application
|
||
|
|
* state at the time of request; as such, no methods are provided to allow
|
||
|
|
* modification of those values. The other values provide such methods, as they
|
||
|
|
* can be restored from $_SERVER or the request body, and may need treatment
|
||
|
|
* during the application (e.g., body parameters may be deserialized based on
|
||
|
|
* content type).
|
||
|
|
*
|
||
|
|
* Additionally, this interface recognizes the utility of introspecting a
|
||
|
|
* request to derive and match additional parameters (e.g., via URI path
|
||
|
|
* matching, decrypting cookie values, deserializing non-form-encoded body
|
||
|
|
* content, matching authorization headers to users, etc). These parameters
|
||
|
|
* are stored in an "attributes" property.
|
||
|
|
*
|
||
|
|
* Requests are considered immutable; all methods that might change state MUST
|
||
|
|
* be implemented such that they retain the internal state of the current
|
||
|
|
* message and return an instance that contains the changed state.
