Request.php

TLDR

The Request.php file in the Illuminate\Http\Client namespace defines the Request class, which is responsible for representing an HTTP request. This class provides methods to retrieve information about the request, such as the request method, URL, headers, body, and request data. It also implements the ArrayAccess interface, allowing access to request data using array syntax.

Methods

method()

This method returns the request method.

url()

This method returns the URL of the request.

hasHeader($key, $value = null)

This method determines if the request has a given header. If the optional $value parameter is provided, it checks if the header has the specified value.

hasHeaders($headers)

This method determines if the request has the given headers. The $headers parameter can be an array of header names or a single header name.

header($key)

This method returns the values for the header with the given name.

headers()

This method returns an array of all request headers.

body()

This method returns the body of the request.

hasFile($name, $value = null, $filename = null)

This method determines if the request contains the given file. The optional $value and $filename parameters can be used to check the value and filename of the file.

data()

This method returns the request's data, which can be form parameters or JSON.

isForm()

This method determines if the request is simple form data.

isJson()

This method determines if the request is JSON.

isMultipart()

This method determines if the request is multipart.

withData(array $data)

This method sets the decoded data on the request.

toPsrRequest()

This method returns the underlying PSR compliant request instance.

offsetExists($offset)

This method determines if the given offset exists in the request data.

offsetGet($offset)

This method retrieves the value for a given offset in the request data.

offsetSet($offset, $value)

This method throws a LogicException since request data cannot be mutated using array access.

offsetUnset($offset)

This method throws a LogicException since request data cannot be mutated using array access.
