Class Response

Implements methods for HTTP responses.

All of the following examples assume that $response is an instance of this class.

Get header values

Header names are case-insensitive, but normalized to Title-Case when the response is parsed.

$val = $response->header('content-type');

Will read the Content-Type header. You can get all set headers using:

$response->header();

You can also get at the headers using object access. When getting headers with object access, you have to use case-sensitive header names:

$val = $response->headers['Content-Type'];

Get the response body

You can access the response body using:

$content = $response->body();

You can also use object access:

$content = $response->body;

If your response body is in XML or JSON you can use special content type specific accessors to read the decoded data. JSON data will be returned as arrays, while XML data will be returned as SimpleXML nodes:

// Get as xml
$content = $response->xml
// Get as json
$content = $response->json

If the response cannot be decoded, null will be returned.

Check the status code

You can access the response status code using:

$content = $response->statusCode();

You can also use object access:

$content = $response->code;

Method Detail

__construct()source public

__construct( array $headers [] , string $body '' )

Constructor

Parameters

array $headers optional []: Unparsed headers.
string $body optional '': The response body.

__get()source public

__get( string $name )

Read values as properties.

Parameters

string $name: Property name.

Returns

mixed

__isset()source public

__isset( string $name )

isset/empty test with -> syntax.

Parameters

string $name: Property name.

Returns

boolean

_decodeGzipBody()source protected

_decodeGzipBody( string $body )

Uncompress a gzip response.

Looks for gzip signatures, and if gzinflate() exists, the body will be decompressed.

Parameters

string $body: Gzip encoded body.

Returns

string

Throws

RuntimeException
When attempting to decode gzip content without gzinflate.

_getJson()source protected

_getJson( )

Get the response body as JSON decoded data.

Returns

mixed

_getXml()source protected

_getXml( )

Get the response body as XML decoded data.

Returns

null|SimpleXMLElement

_parseCookie()source protected

_parseCookie( string $value )

Parse a cookie header into data.

Parameters

string $value: The cookie value to parse.

_parseHeaders()source protected

_parseHeaders( array $headers )

Parses headers if necessary.

Decodes the status code.
Parses and normalizes header names + values.

Parameters

array $headers: Headers to parse.

body()source public

body( callable|null $parser null )

Get the response body.

By passing in a $parser callable, you can get the decoded response content back.

For example to get the json data as an object:

$body = $response->body('json_decode');

Parameters

callable|null $parser optional null: The callback to use to decode the response body.

Returns

mixed
The response body.

Overrides

Cake\Network\Http\Message::body()

cookie()source public

cookie( string|null $name null , boolean $all false )

Read single/multiple cookie values out.

Parameters

string|null $name optional null: The name of the cookie you want. Leave null to get all cookies.
boolean $all optional false: Get all parts of the cookie. When false only the value will be returned.

Returns

mixed

encoding()source public

encoding( )

Get the encoding if it was set.

Returns

string|null

header()source public

header( string|null $name null )

Read single/multiple header value(s) out.

Parameters

string|null $name optional null: The name of the header you want. Leave null to get all headers.

Returns

mixed

Null when the header doesn't exist. An array will be returned when getting all headers or when getting a header that had multiple values set. Otherwise a string will be returned.

isOk()source public

isOk( )

Check if the response was OK

Returns

boolean

isRedirect()source public

isRedirect( )

Check if the response had a redirect status code.

Returns

boolean

statusCode()source public

statusCode( )

Get the status code from the response

Returns

integer
