Method Detail
__construct() ¶ public
__construct(string $url = '', string $method = self::METHOD_GET, array $headers = [], array|string|null $data = null)
Constructor
Provides backwards compatible defaults for some properties.
Parameters
-
string
$url optional The request URL
-
string
$method optional The HTTP method to use.
-
array
$headers optional The HTTP headers to set.
-
array|string|null
$data optional The request body to use.
addHeaders() ¶ protected
addHeaders(array $headers): void
Add an array of headers to the request.
Parameters
-
array
$headers The headers to add.
Returns
void
getHeader() ¶ public
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
-
string
$header Case-insensitive header field name.
Returns
string[]
getHeaderLine() ¶ public
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
-
string
$name Case-insensitive header field name.
Returns
string
getHeaders() ¶ public
getHeaders(): array
Retrieves all message headers.
The keys represent the header name as it will be sent over the wire, and each value is an array of strings associated with the header.
// Represent the headers as a string foreach ($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
array
getProtocolVersion() ¶ public
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
string
getRequestTarget() ¶ public
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
string
getUri() ¶ public
getUri(): UriInterface
Retrieves the URI instance.
This method MUST return a UriInterface instance.
Returns
UriInterface
Links
hasHeader() ¶ public
hasHeader(string $header): bool
Checks if a header exists by the given case-insensitive name.
Parameters
-
string
$header Case-insensitive header name.
Returns
bool
setContent() ¶ protected
setContent(string|array $content): $this
Set the body/payload for the message.
Array data will be serialized with Cake\Http\FormData, and the content-type will be set.
Parameters
-
string|array
$content The body for the request.
Returns
$this
withAddedHeader() ¶ public
withAddedHeader(string $name, 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
-
string
$name Case-insensitive header field name to add.
-
string|string[]
$value Header value(s).
Returns
static
Throws
Exception\InvalidArgumentException
For invalid header names or values.
withBody() ¶ public
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
-
StreamInterface
$body Body.
Returns
static
Throws
Exception\InvalidArgumentException
When the body is not valid.
withHeader() ¶ public
withHeader(string $name, 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
-
string
$name Case-insensitive header field name.
-
string|string[]
$value Header value(s).
Returns
static
Throws
Exception\InvalidArgumentException
For invalid header names or values.
withMethod() ¶ public
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
-
string
$method Case-insensitive method.
Returns
static
Throws
Exception\InvalidArgumentException
For invalid HTTP methods.
withProtocolVersion() ¶ public
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
-
string
$version HTTP protocol version
Returns
static
withRequestTarget() ¶ public
withRequestTarget(string $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
-
string
$requestTarget
Returns
static
Throws
Exception\InvalidArgumentException
If the request target is invalid.
Links
withUri() ¶ public
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
-
UriInterface
$uri New request URI to use.
-
bool
$preserveHost optional Preserve the original state of the Host header.
Returns
static
Links
withoutHeader() ¶ public
withoutHeader(string $name): 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
-
string
$name Case-insensitive header field name to remove.
Returns
static
