Class Request

__construct(string $url = '', string $method = self::METHOD_GET, array $headers = [], array|string|null $data = null)

Constructor

Provides backwards compatible defaults for some properties.

Parameters

addHeaders(array $headers): void

Add an array of headers to the request.

Parameters

Returns

body(string|null $body = null): mixed

Get/set the body/payload for the message.

Array data will be serialized with Cake\Http\FormData, and the content-type will be set.

Parameters

Returns

cookie(string $name, string|null $value = null): mixed

Get/Set cookie values.

Getting a cookie

$request->cookie('session');

Setting one cookie

$request->cookie('session', '123456');

Setting multiple headers

$request->cookie(['test' => 'value', 'split' => 'banana']);

Parameters

Returns

cookies(): array

Get all cookies

Returns

getBody(): StreamInterface

Gets the body of the message.

Returns

getHeader(string $header): string[]

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

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

Returns

getHeaderLine(string $name): string

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

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

Returns

getHeaders(): array

Retrieves all message headers.

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.

// Represent the headers as a string foreach ($message->getHeaders() as $name => $values) { echo $name . ": " . implode(", ", $values); }

// Emit headers iteratively: foreach ($message->getHeaders() as $name => $values) { foreach ($values as $value) { header(sprintf('%s: %s', $name, $value), false); } }

Returns

getMethod(): string

Retrieves the HTTP method of the request.

Returns

getProtocolVersion(): string

Retrieves the HTTP protocol version as a string.

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

Returns

getRequestTarget(): string

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

getUri(): UriInterface

Retrieves the URI instance.

This method MUST return a UriInterface instance.

Returns

Links

hasHeader(string $header): bool

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

Parameters

Returns

header(string|array|null $name = null, string|null $value = null): mixed

Get/Set headers into the request.

You can get the value of a header, or set one/many headers. Headers are set / fetched in a case insensitive way.

Getting headers

$request->header('Content-Type');

Setting one header

$request->header('Content-Type', 'application/json');

Setting multiple headers

$request->header(['Connection' => 'close', 'User-Agent' => 'CakePHP']);

Warning This method mutates the request in-place for backwards compatibility reasons, and is not part of the PSR7 interface.

Parameters

Returns

headers(): array

Get all headers

Returns

method(string|null $method = null): $this|string

Get/Set the HTTP method.

Warning This method mutates the request in-place for backwards compatibility reasons, and is not part of the PSR7 interface.

Parameters

Returns

Throws

url(string|null $url = null): $this|string

Get/Set the url for the request.

Warning This method mutates the request in-place for backwards compatibility reasons, and is not part of the PSR7 interface.

Parameters

Returns

version(string|null $version = null): $this|string

Get/Set HTTP version.

Warning This method mutates the request in-place for backwards compatibility reasons, and is not part of the PSR7 interface.

Parameters

Returns

withAddedHeader(string $header, string|string[] $value): static

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

Existing values for the specified header will be maintained. The new value(s) will be appended to the existing list. If the header did not exist previously, it will be added.

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 header and/or value.

Parameters

Returns

Throws

withBody(StreamInterface $body): static

Return an instance with the specified message body.

The body MUST be a StreamInterface object.

This method MUST be implemented in such a way as to retain the immutability of the message, and MUST return a new instance that has the new body stream.

Parameters

Returns

Throws

withHeader(string $header, string|string[] $value): static

Return an instance with the provided header, replacing any existing values of any headers with the same case-insensitive name.

While header names are case-insensitive, the casing of the header will be preserved by this function, and returned from getHeaders().

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 and/or updated header and value.

Parameters

Returns

Throws

withMethod(string $method): static

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

Returns

Throws

withProtocolVersion(string $version): static

Return an instance with the specified HTTP protocol version.

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

Returns

withRequestTarget(mixed $requestTarget): static

Create a new instance with a 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 a new instance that has the changed request target.

Parameters

Returns

Throws

Links

withUri(UriInterface $uri, bool $preserveHost = false): static

Returns an instance with the provided URI.

This method will 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 will 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, the returned request will not update the Host header of the returned message -- even if the message contains no Host header. This means that a call to getHeader('Host') on the original request MUST equal the return value of a call to getHeader('Host') on 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

Returns

Links

withoutHeader(string $header): static

Return an instance without the specified header.

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

Returns
