Available since version2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/web/Request.php

The web Request class represents an HTTP request.

It encapsulates the $_SERVER variable and resolves its inconsistency among different Web servers. Also it provides an interface to retrieve request parameters from $_POST, $_GET, $_COOKIES and REST parameters sent via other HTTP methods like PUT or DELETE.

Request is configured as an application component in yii\web\Application by default. You can access that instance via Yii::$app->request.

For more details and usage information on Request, see the guide article on requests.

ConstantValueDescriptionDefined By
CSRF_HEADER 'X-CSRF-Token' The name of the HTTP header for sending CSRF token. yii\web\Request
CSRF_MASK_LENGTH 8 The length of the CSRF token mask. Deprecated since 2.0.12. The mask length is now equal to the token length. yii\web\Request

Property Details

$cookieValidationKey public property

A secret key used for cookie validation. This property must be set if $enableCookieValidation is true.

$csrfCookie public property

The configuration for creating the CSRF cookie. This property is used only when both $enableCsrfValidation and $enableCsrfCookie are true.

public array $csrfCookie = ['httpOnly' => true]
$csrfParam public property

The name of the token used to prevent CSRF. Defaults to '_csrf'. This property is used only when $enableCsrfValidation is true.

public string $csrfParam '_csrf'
$enableCookieValidation public property

Whether cookies should be validated to ensure they are not tampered. Defaults to true.

$enableCsrfCookie public property

Whether to use cookie to persist CSRF token. If false, CSRF token will be stored in session under the name of $csrfParam. Note that while storing CSRF tokens in session increases security, it requires starting a session for every page, which will degrade your site performance.

public boolean $enableCsrfCookie true
$enableCsrfValidation public property

Whether to enable CSRF (Cross-Site Request Forgery) validation. Defaults to true. When CSRF validation is enabled, forms submitted to an Yii Web application must be originated from the same application. If not, a 400 HTTP exception will be raised.

Note, this feature requires that the user client accepts cookie. Also, to use this feature, forms submitted via POST method must contain a hidden input whose name is specified by $csrfParam. You may use yii\helpers\Html::beginForm() to generate his hidden input.

In JavaScript, you may get the values of $csrfParam and \yii\web\csrfToken via yii.getCsrfParam() and yii.getCsrfToken(), respectively. The yii\web\YiiAsset asset must be registered. You also need to include CSRF meta tags in your pages by using yii\helpers\Html::csrfMetaTags().

See also:

$ipHeaders public property (available since version 2.0.13)

List of headers where proxies store the real client IP. It's not advisable to put insecure headers here. To use the Forwarded header according to RFC 7239, the header must be added to $secureHeaders list. The match of header names is case-insensitive.

See also:

public string[] $ipHeaders = ['X-Forwarded-For']
$methodParam public property

The name of the POST parameter that is used to indicate if a request is a PUT, PATCH or DELETE request tunneled through POST. Defaults to '_method'.

See also:

public string $methodParam '_method'
$parsers public property

The parsers for converting the raw HTTP request body into \yii\web\bodyParams. The array keys are the request Content-Types, and the array values are the corresponding configurations for creating the parser objects. A parser must implement the yii\web\RequestParserInterface.

To enable parsing for JSON requests you can use the yii\web\JsonParser class like in the following example:

[
    'application/json' => 'yii\web\JsonParser',
]

To register a parser for parsing all request types you can use '*' as the array key. This one will be used as a fallback in case no other types match.

See also getBodyParams().

public array $parsers = []
$secureHeaders public property (available since version 2.0.13)

Lists of headers that are, by default, subject to the trusted host configuration. These headers will be filtered unless explicitly allowed in $trustedHosts. If the list contains the Forwarded header, processing will be done according to RFC 7239. The match of header names is case-insensitive.

See also:

public array $secureHeaders = ['X-Forwarded-For''X-Forwarded-Host''X-Forwarded-Proto''Front-End-Https''X-Rewrite-Url']
$secureProtocolHeaders public property (available since version 2.0.13)

List of headers to check for determining whether the connection is made via HTTPS. The array keys are header names and the array value is a list of header values that indicate a secure connection. The match of header names and values is case-insensitive. It's not advisable to put insecure headers here.

See also:

public array $secureProtocolHeaders = ['X-Forwarded-Proto' => ['https'], 'Front-End-Https' => ['on']]
$trustedHosts public property (available since version 2.0.13)

The configuration for trusted security related headers.

An array key is an IPv4 or IPv6 IP address in CIDR notation for matching a client.

An array value is a list of headers to trust. These will be matched against $secureHeaders to determine which headers are allowed to be sent by a specified host. The case of the header names must be the same as specified in $secureHeaders.

For example, to trust all headers listed in $secureHeaders for IP addresses in range 192.168.0.0-192.168.0.254 write the following:

[
    '192.168.0.0/24',
]

To trust just the X-Forwarded-For header from 10.0.0.1, use:

[
    '10.0.0.1' => ['X-Forwarded-For']
]

Default is to trust all headers except those listed in $secureHeaders from all hosts. Matches are tried in order and searching is stopped when IP matches.

Info: Matching is performed using yii\validators\IpValidator. See yii\validators\IpValidator::::setRanges() and yii\validators\IpValidator::$networks for advanced matching.

See also $secureHeaders.

public array $trustedHosts = []

The returned URL does not have an ending slash.

By default this value is based on the user request information. This method will return the value of $_SERVER['HTTP_HOST'] if it is available or $_SERVER['SERVER_NAME'] if not. You may want to check out the PHP documentation for more information on these variables.

You may explicitly specify it by setting the hostInfo property.

Warning: Dependent on the server configuration this information may not be reliable and may be faked by the user sending the HTTP request. If the webserver is configured to serve the same site independent of the value of the Host header, this value is not reliable. In such situations you should either fix your webserver configuration or explicitly set the value by setting the hostInfo property. If you don't have access to the server configuration, you can setup yii\filters\HostControl filter at application level in order to protect against such kind of attack.

See also setHostInfo().

public string|null getHostInfo ( )
return string|null

Schema and hostname part (with port number if needed) of the request URL (e.g. http://www.yiiframework.com), null if can't be obtained from $_SERVER and wasn't set.
