getPath() : string
Retrieve the path component of the URI.
The path can either be empty or absolute (starting with a slash) or
rootless (not starting with a slash). Implementations MUST support all
Normally, the empty path "" and absolute path "/" are considered equal as
defined in RFC 7230 Section 2.7.3. But this method MUST NOT automatically
do this normalization because in contexts with a trimmed base path, e.g.
the front controller, this difference becomes significant. It's the task
of the user to handle both "" and "/".
The value returned MUST be percent-encoded, but MUST NOT double-encode
any characters. To determine what characters to encode, please refer to
RFC 3986, Sections 2 and 3.3.
As an example, if the value should include a slash ("/") not intended as
delimiter between path segments, that value MUST be passed in encoded
form (e.g., "%2F") to the instance.
