TYPO3 main API: Request

Request extends Message implements RequestInterface

Default implementation for the RequestInterface of the PSR-7 standard It is the base for any request sent BY PHP.

Please see ServerRequest for the typical use cases in the framework.

filter()

Filter a header value


    public
                    filter(string $value) : string

Ensures CRLF header injection vectors are filtered.

Per RFC 7230, only VISIBLE ASCII characters, spaces, and horizontal tabs are allowed in values; header continuations MUST consist of a single CRLF sequence followed by a space or horizontal tab.

This method filters any values not allowed from the string, and is lossy.

Parameters

$value : string

Return values

string

getBody()

Gets the body of the message.


    public
                    getBody() : StreamInterface

Return values

StreamInterface —

Returns the body as a stream.

getHeader()

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.

getHeaderLine()

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.

getHeaders()

Retrieves all message header values.


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

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);
        }
    }

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

Return values

array<string|int, mixed> —

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, defaults to GET


    public
                    getMethod() : string

Return values

string

getProtocolVersion()

    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

getUri()

Parameters

$name : string: Case-insensitive header field name.

Return values

bool —

Returns true if any header names match the given header name using a case-insensitive string comparison. Returns false if no matching header name is found in the message.

isValidHeaderValue()

Checks if an HTTP header value is valid.


    public
                    isValidHeaderValue(string $value) : bool

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

$name : string: Case-insensitive header field name.

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.

Return values

static

withoutHeader()

Return an instance without the specified header.


    public
                    withoutHeader(string $name) : static

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.

Return values

static

withRequestTarget()

Return an instance with the specific request-target.


    public
                    withRequestTarget(mixed $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 : mixed

Return values

static

withUri()

Returns an instance with the provided URI.


    public
                    withUri(UriInterface $uri[, bool $preserveHost = 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 to true, this method interacts with the Host header in the following ways:

If the 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.
