RequestInterface extendsMessageInterface

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

getBody() : StreamInterface

Gets the body of the message.

getHeader() : array<string|int, string>

Retrieves a message header value by the given case-insensitive name.

getHeaderLine() : string

Retrieves a comma-separated string of the values for a single header.

getHeaders() : array<string|int, array<string|int, string>>

Retrieves all message header values.

getMethod() : string

Retrieves the HTTP method of the request.

getProtocolVersion() : string

Retrieves the HTTP protocol version as a string.

getRequestTarget() : string

Retrieves the message's request target.

getUri() : UriInterface

Retrieves the URI instance.

hasHeader() : bool

Checks if a header exists by the given case-insensitive name.

withAddedHeader() : static

Return an instance with the specified header appended with the given value.

withBody() : static

Return an instance with the specified message body.

withHeader() : static

Return an instance with the provided value replacing the specified header.

withMethod() : static

Return an instance with the provided HTTP method.

withoutHeader() : static

Return an instance without the specified header.

withProtocolVersion() : static

Return an instance with the specified HTTP protocol version.

getBody()

Gets the body of the message.

public getBody() : [StreamInterface](class-Psr.Http.Message.StreamInterface.html)

Return values

StreamInterface —

Returns the body as a stream.

Retrieves a message header value by the given case-insensitive name.

public getHeader(string $name) : array<string|int, string>

This method returns an array of all the header values of the given case-insensitive header name.

If the header does not appear in the message, this method MUST return an empty array.

Parameters

$name : string

Case-insensitive header field name.

Return values

array<string|int, string> —

An array of string values as provided for the given header. If the header does not appear in the message, this method MUST return an empty array.

Retrieves a comma-separated string of the values for a single header.

public getHeaderLine(string $name) : string

This method returns all of the header values of the given case-insensitive header name as a string concatenated together using a comma.

NOTE: Not all header values may be appropriately represented using comma concatenation. For such headers, use getHeader() instead and supply your own delimiter when concatenating.

If the header does not appear in the message, this method MUST return an empty string.

Parameters

$name : string

Case-insensitive header field name.

Return values

string —

A string of values as provided for the given header concatenated together using a comma. If the header does not appear in the message, this method MUST return an empty string.

Retrieves all message header values.

public getHeaders() : array<string|int, array<string|int, string>>

The keys represent the header name as it will be sent over the wire, and each value is an array of strings associated with the header.

}

While header names are not case-sensitive, getHeaders() will preserve the exact case in which headers were originally specified.

Return values

array<string|int, array<string|int, string>> —

Returns an associative array of the message's headers. Each key MUST be a header name, and each value MUST be an array of strings for that header.

getMethod()

Retrieves the HTTP method of the request.

public getMethod() : string

Return values

string —

Returns the request method.

getProtocolVersion()

Retrieves the HTTP protocol version as a string.

public getProtocolVersion() : string

The string MUST contain only the HTTP version number (e.g., "1.1", "1.0").

Return values

string —

HTTP protocol version.

getRequestTarget()

Retrieves the message's request target.

public getRequestTarget() : string

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 "/".

Return values

string

Parameters

$name : string

Case-insensitive header field name.

$value : string|array<string|int, string>

Header value(s).

Tags

throws

InvalidArgumentException

for invalid header names or values.

Return values

static

withMethod()

Return an instance with the provided HTTP method.

public withMethod(string $method) : static

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 : string

Case-sensitive method.

Tags

throws

InvalidArgumentException

for invalid HTTP methods.

Return values

static

Return an instance without the specified header.

public withoutHeader(string $name) : static

Header resolution MUST be done without case-sensitivity.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return an instance that removes the named header.

Parameters

$name : string

Case-insensitive header field name to remove.

Return values

static

withProtocolVersion()

Return an instance with the specified HTTP protocol version.

public withProtocolVersion(string $version) : static

The version string MUST contain only the HTTP version number (e.g., "1.1", "1.0").

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 protocol version.

Parameters

$version : string

HTTP protocol version

Return values

static

withRequestTarget()

Return an instance with the specific request-target.

public withRequestTarget(string $requestTarget) : static

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

$requestTarget : string

Tags

link

(for the various request-target forms allowed in request messages)

Return values

static

withUri()

Returns an instance with the provided URI.

public withUri([UriInterface](class-Psr.Http.Message.UriInterface.html) <math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi>u</mi><mi>r</mi><mi>i</mi><mo stretchy="false">[</mo><mo separator="true">,</mo><mi>b</mi><mi>o</mi><mi>o</mi><mi>l</mi></mrow><annotation encoding="application/x-tex">uri[, bool </annotation></semantics></math>uri[,boolpreserveHost = false ]) : static

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 totrue, 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 : UriInterface

New request URI to use.

$preserveHost : bool = false

Preserve the original state of the Host header.
