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.

参见 $enableCsrfValidation.

Filters headers according to the $trustedHosts.

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.

参见：

• getAuthUser() to get only username.
• getAuthPassword() to get only password.

参见 getAuthCredentials() to get both username and password in one call.

参见 getAuthCredentials() to get both username and password in one call.

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.

参见 setScriptUrl().

Returns the named request body parameter value.

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

参见：

• 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.

参见：

• 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 generated in a way to prevent BREACH attacks. It 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 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.

参见 setHostInfo().

Returns the host part of the current request URL.

Value is calculated from current hostInfo property.

Warning: The content of this value may not be reliable, dependent on the server configuration. Please refer to getHostInfo() for more information.

参见 getHostInfo().

Creates instance of yii\validators\IpValidator.

You can override this method to adjust validator or implement different matching strategy.

Returns whether this is an AJAX (XMLHttpRequest) request.

Note that jQuery doesn't set the header in case of cross domain requests: https://stackoverflow.com/questions/8163703/cross-domain-ajax-doesnt-send-x-requested-with-header

Returns whether this is an Adobe Flash or Flex request.

Returns whether this is a GET request.

Returns whether this is a HEAD request.

Returns whether this is an OPTIONS request.

Returns whether this is a POST request.

Returns whether this is a PUT request.

Return if the request is sent via secure channel (https).

Returns the method of the current request (e.g. GET, POST, HEAD, PUT, PATCH, DELETE).

Returns the URL origin of a CORS request.

The return value is taken from the Origin header sent by the browser.

Note that the origin request header indicates where a fetch originates from. It doesn't include any path information, but only the server name. It is sent with a CORS requests, as well as with POST requests. It is similar to the referer header, but, unlike this header, it doesn't disclose the whole path. Please refer to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Origin for more information.

参见 getHeaders().

Returns the path info of the currently requested URL.

A path info refers to the part that is after the entry script and before the question mark (query string). The starting and ending slashes are both removed.

Returns the port to use for insecure requests.

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

参见 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.

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;';
