Class yii\web\Request

Creates a cookie with a randomly generated CSRF token.

Initial values specified in $csrfCookie will be applied to the generated cookie.

See also $enableCsrfValidation.

Generates an unmasked random token used to perform CSRF validation.

Returns GET parameter with a given name. If name isn't specified, returns an array of all GET parameters.

Returns the currently requested absolute URL.

This is a shortcut to the concatenation of $hostInfo and $url.

Returns the content types acceptable by the end user.

This is determined by the Accept HTTP header. For example,

$_SERVER['HTTP_ACCEPT'] = 'text/plain; q=0.5, application/json; version=1.0, application/xml; version=2.0;';
$types = $request->getAcceptableContentTypes();
print_r($types);
// displays:
// [
//     'application/json' => ['q' => 1, 'version' => '1.0'],
//      'application/xml' => ['q' => 1, 'version' => '2.0'],
//           'text/plain' => ['q' => 0.5],
// ]

Returns the languages acceptable by the end user.

This is determined by the Accept-Language HTTP header.

Returns the relative URL for the application.

This is similar to $scriptUrl except that it does not include the script file name, and the ending slashes are removed.

See also setScriptUrl().

Returns the named request body parameter value.

If the parameter does not exist, the second parameter passed to this method will be returned.

See also:

• getBodyParams()
• setBodyParams()

Returns the request parameters given in the request body.

Request parameters are determined using the parsers configured in $parsers property. If no parsers are configured for the current $contentType it uses the PHP function mb_parse_str() to parse the request body.

See also:

• getMethod()
• getBodyParam()
• setBodyParams()

Returns request content-type The Content-Type header field indicates the MIME type of the data contained in getRawBody() or, in the case of the HEAD method, the media type that would have been sent had the request been a GET.

For the MIME-types the user expects in response, see $acceptableContentTypes.

Returns the cookie collection.

Through the returned cookie collection, you may access a cookie using the following syntax:

$cookie = $request->cookies['name']
if ($cookie !== null) {
    $value = $cookie->value;
}

// alternatively
$value = $request->cookies->getValue('name');

Returns the token used to perform CSRF validation.

This token is a masked version of \yii\web\rawCsrfToken to prevent BREACH attacks. This token may be passed along via a hidden field of an HTML form or an HTTP header value to support CSRF validation.

Gets the Etags.

Returns the header collection.

The header collection contains incoming HTTP headers.

Returns the schema and host part of the current request URL.

The returned URL does not have an ending slash. By default this is determined based on the user request information. You may explicitly specify it by setting the hostInfo property.

See also setHostInfo().

Returns whether this is an AJAX (XMLHttpRequest) request.

Returns whether this is a DELETE request.

Returns the port to use for insecure requests.

Defaults to 80, or the port specified by the server if the current request is insecure.

See also setPort().

Returns the user-preferred language that should be used by this application.

The language resolution is based on the user preferred languages and the languages supported by the application. The method will try to find the best match.

Returns the named GET parameter value.

If the GET parameter does not exist, the second parameter passed to this method will be returned.

This method will return the contents of $_GET if params where not explicitly set.

See also setQueryParams().

Returns the raw HTTP request body.

Returns the URL referrer, null if not present

Returns the entry script file path.

The default implementation will simply return $_SERVER['SCRIPT_FILENAME'].

Returns the relative URL of the entry script.

The implementation of this method referenced Zend_Controller_Request_Http in Zend Framework.

Returns the port to use for secure requests.

Defaults to 443, or the port specified by the server if the current request is secure.

See also setSecurePort().

Returns the server name.

Returns the server port number.

Returns the currently requested relative URL.

This refers to the portion of the URL that is after the $hostInfo part. It includes the $queryString part if any.

Converts $_COOKIE into an array of yii\web\Cookie.

Loads the CSRF token from cookie or session.

Parses the given Accept (or Accept-Language) header.

This method will return the acceptable values with their quality scores and the corresponding parameters as specified in the given Accept header. The array keys of the return value are the acceptable values, while the array values consisting of the corresponding quality scores and parameters. The acceptable values with the highest quality scores will be returned first. For example,

$header = 'text/plain; q=0.5, application/json; version=1.0, application/xml; version=2.0;';
$accepts = $request->parseAcceptHeader($header);
print_r($accepts);
// displays:
// [
//     'application/json' => ['q' => 1, 'version' => '1.0'],
//      'application/xml' => ['q' => 1, 'version' => '2.0'],

Sets the schema and host part of the application URL.

Sets the path info of the current request.

This method is mainly provided for testing purpose.

Sets the port to use for insecure requests.

This setter is provided in case a custom port is necessary for certain server configurations.

Sets the request $queryString parameters.

• getQueryParam()
• getQueryParams()

Sets the raw HTTP request body, this method is mainly used by test scripts to simulate raw HTTP requests.

Sets the entry script file path.

The entry script file path normally can be obtained from $_SERVER['SCRIPT_FILENAME']. If your server configuration does not return the correct value, you may configure this property to make it right.

Sets the relative URL for the application entry script.

This setter is provided in case the entry script URL cannot be determined on certain Web servers.

Sets the port to use for secure requests.

The URI must refer to the portion that is after $hostInfo. Note that the URI should be URL-encoded.

Performs the CSRF validation.

This method will validate the user-provided CSRF token by comparing it with the one stored in cookie or session. This method is mainly called in yii\web\Controller::beforeAction().

Note that the method will NOT perform CSRF validation if $enableCsrfValidation is false or the HTTP method is among GET, HEAD or OPTIONS.
