Interfaces

The purpose of this list is to help in finding the methods when working with PSR-7. This can be considered as a cheatsheet for PSR-7 interfaces.

The interfaces defined in PSR-7 are the following:

Class Name	Description
Psr\Http\Message\MessageInterface	Representation of a HTTP message
Psr\Http\Message\RequestInterface	Representation of an outgoing, client-side request.
Psr\Http\Message\ServerRequestInterface	Representation of an incoming, server-side HTTP request.
Psr\Http\Message\ResponseInterface	Representation of an outgoing, server-side response.
Psr\Http\Message\StreamInterface	Describes a data stream
Psr\Http\Message\UriInterface	Value object representing a URI.
Psr\Http\Message\UploadedFileInterface	Value object representing a file uploaded through an HTTP request.

Psr\Http\Message\MessageInterface Methods

Method Name	Description	Notes
getProtocolVersion()	Retrieve HTTP protocol version	1.0 or 1.1
withProtocolVersion($version)	Returns new message instance with given HTTP protocol version
getHeaders()	Retrieve all HTTP Headers	Request Header List, Response Header List
hasHeader($name)	Checks if HTTP Header with given name exists
getHeader($name)	Retrieves a array with the values for a single header
getHeaderLine($name)	Retrieves a comma-separated string of the values for a single header
withHeader($name, $value)	Returns new message instance with given HTTP Header	if the header existed in the original instance, replaces the header value from the original message with the value provided when creating the new instance.
withAddedHeader($name, $value)	Returns new message instance with appended value to given header	If header already exists value will be appended, if not a new header will be created
withoutHeader($name)	Removes HTTP Header with given name
getBody()	Retrieves the HTTP Message Body	Returns object implementing StreamInterface
withBody(StreamInterface $body)	Returns new message instance with given HTTP Message Body

Psr\Http\Message\RequestInterface Methods

Same methods as Psr\Http\Message\MessageInterface + the following methods:

Method Name	Description	Notes
getRequestTarget()	Retrieves the message's request target	origin-form, absolute-form, authority-form, asterisk-form (RFC7230)
withRequestTarget($requestTarget)	Return a new message instance with the specific request-target
getMethod()	Retrieves the HTTP method of the request.	GET, HEAD, POST, PUT, DELETE, CONNECT, OPTIONS, TRACE (defined in RFC7231), PATCH (defined in RFC5789)
withMethod($method)	Returns a new message instance with the provided HTTP method
getUri()	Retrieves the URI instance
withUri(UriInterface $uri, $preserveHost = false)	Returns a new message instance with the provided URI

Psr\Http\Message\ServerRequestInterface Methods

Same methods as Psr\Http\Message\RequestInterface + the following methods:

Method Name	Description	Notes
getServerParams()	Retrieve server parameters	Typically derived from $_SERVER
getCookieParams()	Retrieves cookies sent by the client to the server.	Typically derived from $_COOKIES
withCookieParams(array $cookies)	Returns a new request instance with the specified cookies
withQueryParams(array $query)	Returns a new request instance with the specified query string arguments
getUploadedFiles()	Retrieve normalized file upload data
withUploadedFiles(array $uploadedFiles)	Returns a new request instance with the specified uploaded files
getParsedBody()	Retrieve any parameters provided in the request body
withParsedBody($data)	Returns a new request instance with the specified body parameters
getAttributes()	Retrieve attributes derived from the request
getAttribute($name, $default = null)	Retrieve a single derived request attribute
withAttribute($name, $value)	Returns a new request instance with the specified derived request attribute
withoutAttribute($name)	Returns a new request instance that without the specified derived request attribute

Psr\Http\Message\ResponseInterface Methods:

Same methods as Psr\Http\Message\MessageInterface + the following methods:

Method Name	Description	Notes
getStatusCode()	Gets the response status code.
withStatus($code, $reasonPhrase = '')	Returns a new response instance with the specified status code and, optionally, reason phrase.
getReasonPhrase()	Gets the response reason phrase associated with the status code.

Psr\Http\Message\StreamInterface Methods

Method Name	Description	Notes
__toString()	Reads all data from the stream into a string, from the beginning to end.
close()	Closes the stream and any underlying resources.
detach()	Separates any underlying resources from the stream.
getSize()	Get the size of the stream if known.
eof()	Returns true if the stream is at the end of the stream.
isSeekable()	Returns whether or not the stream is seekable.
seek($offset, $whence = SEEK_SET)	Seek to a position in the stream.
rewind()	Seek to the beginning of the stream.
isWritable()	Returns whether or not the stream is writable.
write($string)	Write data to the stream.
isReadable()	Returns whether or not the stream is readable.
read($length)	Read data from the stream.
getContents()	Returns the remaining contents in a string
getMetadata($key = null)()	Get stream metadata as an associative array or retrieve a specific key.

Psr\Http\Message\UriInterface Methods

Method Name	Description	Notes
getScheme()	Retrieve the scheme component of the URI.
getAuthority()	Retrieve the authority component of the URI.
getUserInfo()	Retrieve the user information component of the URI.
getHost()	Retrieve the host component of the URI.
getPort()	Retrieve the port component of the URI.
getPath()	Retrieve the path component of the URI.
getQuery()	Retrieve the query string of the URI.
getFragment()	Retrieve the fragment component of the URI.
withScheme($scheme)	Return an instance with the specified scheme.
withUserInfo($user, $password = null)	Return an instance with the specified user information.
withHost($host)	Return an instance with the specified host.
withPort($port)	Return an instance with the specified port.
withPath($path)	Return an instance with the specified path.
withQuery($query)	Return an instance with the specified query string.
withFragment($fragment)	Return an instance with the specified URI fragment.
__toString()	Return the string representation as a URI reference.

Psr\Http\Message\UploadedFileInterface Methods

Method Name	Description	Notes
getStream()	Retrieve a stream representing the uploaded file.
moveTo($targetPath)	Move the uploaded file to a new location.
getSize()	Retrieve the file size.
getError()	Retrieve the error associated with the uploaded file.
getClientFilename()	Retrieve the filename sent by the client.
getClientMediaType()	Retrieve the media type sent by the client.

RequestInterface, ServerRequestInterface, ResponseInterface extend MessageInterface because the Request and the Response are HTTP Messages. When using ServerRequestInterface, both RequestInterface and Psr\Http\Message\MessageInterface methods are considered.
