CHttpRequest encapsulates the $_SERVER variable and resolves its inconsistency among different Web servers.

CHttpRequest also manages the cookies sent from and sent to the user. By setting enableCookieValidation to true, cookies sent from the user will be validated to see if they are tampered. The property cookies returns the collection of cookies. For more details, see CCookieCollection.

CHttpRequest is a default application component loaded by CWebApplication. It can be accessed via CWebApplication::getRequest().

属性详细

acceptTypes 属性只读 public string getAcceptTypes()

Returns user browser accept types, null if not present.

baseUrl 属性 public string getBaseUrl(boolean $absolute=false)
public void setBaseUrl(string $value)

Returns the relative URL for the application. This is similar to scriptUrl except that it does not have the script file name, and the ending slashes are stripped off.

参见

setScriptUrl

browser 属性只读 public array getBrowser(string $userAgent=NULL)

Returns information about the capabilities of user browser.

参见

http://www.php.net/manual/en/function.get-browser.php

cookies 属性只读 public CCookieCollection getCookies()

Returns the cookie collection. The result can be used like an associative array. Adding CHttpCookie objects to the collection will send the cookies to the client; and removing the objects from the collection will delete those cookies on the client.

csrfCookie 属性 public array $csrfCookie;

the property values (in name-value pairs) used to initialize the CSRF cookie. Any property of CHttpCookie may be initialized. This property is effective only when enableCsrfValidation is true.

csrfToken 属性只读 public string getCsrfToken()

Returns the random token used to perform CSRF validation. The token will be read from cookie first. If not found, a new token will be generated.

参见

By setting this property to true, 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. You also need to use CHtml::form or CHtml::statefulForm to generate the needed HTML forms in your pages.

参见

http://seclab.stanford.edu/websec/csrf/csrf.pdf

hostInfo 属性 public string getHostInfo(string $schema='')

Sends existing file to a browser as a download using x-sendfile.

X-Sendfile is a feature allowing a web application to redirect the request for a file to the webserver that in turn processes the request, this way eliminating the need to perform tasks like reading the file and sending it to the user. When dealing with a lot of files (or very big files) this can lead to a great increase in performance as the web application is allowed to terminate earlier while the webserver is handling the request.

The request is sent to the server through a special non-standard HTTP-header. When the web server encounters the presence of such header it will discard all output and send the file specified by that header using web server internals including all optimizations like caching-headers.

As this header directive is non-standard different directives exists for different web servers applications:

Apache: X-Sendfile
Lighttpd v1.4: X-LIGHTTPD-send-file
Lighttpd v1.5: X-Sendfile
Nginx: X-Accel-Redirect
Cherokee: X-Sendfile and X-Accel-Redirect

So for this method to work the X-SENDFILE option/module should be enabled by the web server and a proper xHeader should be sent.

Note: This option allows to download files that are not under web folders, and even files that are otherwise protected (deny from all) like .htaccess

Side effects: If this option is disabled by the web server, when this method is called a download configuration dialog will open but the downloaded file will have 0 bytes.

Example:

<?php Yii::app()->request->xSendFile('/home/user/Pictures/picture1.jpg',array(     'saveName'=>'image1.jpg',     'mimeType'=>'image/jpeg',     'terminate'=>false, ));
?>
