Representation of an outgoing, client-side request.
Per the HTTP specification, this interface includes properties for
each of the following:
- Protocol version
- HTTP method
- URI
- Headers
- Message body
During construction, implementations MUST attempt to set the Host header from
a provided URI if no Host header is provided.
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.
| Methods |
public
|
getRequestTarget(): string
Retrieves the message's request target.
Retrieves the message's request target.
Retrieves the message's request-target either as it will appear (for
clients), as it appeared at request (for servers), or as it was
specified for the instance (see withRequestTarget()).
In most cases, this will be the origin-form of the composed URI,
unless a value was provided to the concrete implementation (see
withRequestTarget() below).
If no URI is available, and no request-target has been specifically
provided, this method MUST return the string "/".
|
#
|
public
|
withRequestTarget(string $requestTarget): static
Return an instance with the specific request-target.
Return an instance with the specific request-target.
If the request needs a non-origin-form request-target — e.g., for
specifying an absolute-form, authority-form, or asterisk-form —
this method may be used to create an instance with the specified
request-target, verbatim.
This method MUST be implemented in such a way as to retain the
immutability of the message, and MUST return an instance that has the
changed request target.
|
#
|
public
|
getMethod(): string
Retrieves the HTTP method of the request.
Retrieves the HTTP method of the request.
Returns
Returns the request method.
|
#
|
public
|
withMethod(string $method): static
Return an instance with the provided HTTP method.
Return an instance with the provided HTTP method.
While HTTP method names are typically all uppercase characters, HTTP
method names are case-sensitive and thus implementations SHOULD NOT
modify the given string.
This method MUST be implemented in such a way as to retain the
immutability of the message, and MUST return an instance that has the
changed request method.
Parameters
| $method |
Case-sensitive method.
|
Throws
|
#
|
public
|
getUri(): UriInterface
Retrieves the URI instance.
Retrieves the URI instance.
This method MUST return a UriInterface instance.
Returns
Returns a UriInterface instance
representing the URI of the request.
|
#
|
public
|
withUri(UriInterface $uri, bool $preserveHost = false): static
Returns an instance with the provided URI.
Returns an instance with the provided URI.
This method MUST update the Host header of the returned request by
default if the URI contains a host component. If the URI does not
contain a host component, any pre-existing Host header MUST be carried
over to the returned request.
You can opt-in to preserving the original state of the Host header by
setting $preserveHost to true. When $preserveHost is set to
true, this method interacts with the Host header in the following ways:
- If the Host header is missing or empty, and the new URI contains
a host component, this method MUST update the Host header in the returned
request.
- If the Host header is missing or empty, and the new URI does not contain a
host component, this method MUST NOT update the Host header in the returned
request.
- If a Host header is present and non-empty, this method MUST NOT update
the Host header in the returned request.
This method MUST be implemented in such a way as to retain the
immutability of the message, and MUST return an instance that has the
new UriInterface instance.
Parameters
| $uri |
New request URI to use.
|
| $preserveHost |
Preserve the original state of the Host header.
