Interface RequestInterface
- Psr\Http\Message\RequestInterface implements Psr\Http\Message\MessageInterface
- Namespace: Psr\Http\Message
- Located at Http/Message/RequestInterface.php
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 Details
string getRequestTarget ( )
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 "/".
Returns
string |
static withRequestTarget ( mixed $requestTarget )
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.
Parameters
mixed | $requestTarget |
Returns
static |
Link
string getMethod ( )
Retrieves the HTTP method of the request.
Returns
string Returns the request method. |
static withMethod ( string $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
string | $method | Case-sensitive method. |
Returns
static |
Exceptions
InvalidArgumentException for invalid HTTP methods. |
Psr\Http\Message\UriInterface
getUri (
)
Retrieves the URI instance.
This method MUST return a UriInterface instance.
Returns
Psr\Http\Message\UriInterface Returns a UriInterface instance representing the URI of the request. |
Link
static
withUri (
Psr\Http\Message\UriInterface
$uri,
boolean
$preserveHost = false
)
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
Psr\Http\Message\UriInterface |
$uri | New request URI to use. |
boolean | $preserveHost = false | Preserve the original state of the Host header. |
Returns
static |
