string __toString()
Returns the request as a string.
Return Value
string | The request |
overrideGlobals()
Overrides the PHP global variables according to this request instance.
It overrides $GET, $POST, $REQUEST, $SERVER, $COOKIE. $FILES is never overridden, see rfc1867
static setTrustedProxies(array $proxies, int $trustedHeaderSet)
Sets a list of trusted proxies.
You should only list the reverse proxies that you manage directly.
Parameters
array | $proxies | A list of trusted proxies |
int | $trustedHeaderSet | A bit field of Request::HEADER_*, to set which headers to trust from your proxies |
Exceptions
InvalidArgumentException | When $trustedHeaderSet is invalid |
static array getTrustedProxies()
Gets the list of trusted proxies.

array | An array of trusted proxies |
static int getTrustedHeaderSet()
Gets the set of trusted headers from trusted proxies.
Return Value
int | A bit field of Request::HEADER_* that defines which headers are trusted from your proxies |
static setTrustedHosts(array $hostPatterns)
Sets a list of trusted host patterns.
You should only list the hosts you manage using regexs.
Parameters
array | $hostPatterns | A list of trusted host patterns |
static array getTrustedHosts()
Gets the list of trusted host patterns.
Return Value
array | An array of trusted host patterns |
static string normalizeQueryString(string $qs)

It builds a normalized query string, where keys/value pairs are alphabetized, have consistent escaping and unneeded delimiters are removed.
Parameters
string | $qs | Query string |
Return Value
string | A normalized query string for the Request |
static enableHttpMethodParameterOverride()
Enables support for the _method request parameter to determine the intended HTTP method.
Be warned that enabling this feature might lead to CSRF issues in your code. Check that you are using CSRF tokens when required. If the HTTP method parameter override is enabled, an html-form with method "POST" can be altered and used to send a "PUT" or "DELETE" request via the _method request parameter. If these methods are not protected against CSRF, this presents a possible vulnerability.
The HTTP method can only be overridden when the real HTTP method is POST.
static bool getHttpMethodParameterOverride()
Checks whether support for the _method request parameter is enabled.
Return Value
bool | True when the _method request parameter is enabled, false otherwise |
mixed get(string $key, mixed $default = null)
Gets a "parameter" value from any bag.
This method is mainly useful for libraries that want to provide some flexibility. If you don't need the flexibility in controllers, it is better to explicitly get request parameters from the appropriate public property instead (attributes, query, request).
Order of precedence: PATH (routing placeholders or custom attributes), GET, BODY
Parameters
string | $key | The key |
mixed | $default | The default value if the parameter key does not exist |
Return Value
mixed |
SessionInterface|null getSession()
Gets the Session.
Return Value
SessionInterface|null | The session |
bool hasPreviousSession()
Whether the request contains a Session which was started in one of the previous requests.
Return Value
bool |
bool hasSession()
Whether the request contains a Session object.
This method does not give any information about the state of the session object, like whether the session is started or not. It is just a way to check if this Request is associated with a Session instance.
Return Value
bool | true when the Request contains a Session object, false otherwise |
setSession(SessionInterface $session)
Sets the Session.
Parameters
SessionInterface | $session | The Session |
array getClientIps()
Returns the client IP addresses.
In the returned array the most trusted IP address is first, and the least trusted one last. The "real" client IP address is the last one, but this is also the least trusted one. Trusted proxies are stripped.
Use this method carefully; you should use getClientIp() instead.
Return Value
array | The client IP addresses |
See also
getClientIp() |
string|null getClientIp()
Returns the client IP address.
This method can read the client IP address from the "X-Forwarded-For" header when trusted proxies were set via "setTrustedProxies()". The "X-Forwarded-For" header value is a comma+space separated list of IP addresses, the left-most being the original client, and each successive proxy that passed the request adding the IP address where it received the request from.
Return Value
string|null | The client IP address |
See also
getClientIps() | |
http://en.wikipedia.org/wiki/X-Forwarded-For |
string getScriptName()
Returns current script name.
Return Value
string |
string getPathInfo()
Returns the path being requested relative to the executed script.
The path info always starts with a /.
Suppose this request is instantiated from /mysite on localhost:
- http://localhost/mysite returns an empty string
- http://localhost/mysite/about returns '/about'
- http://localhost/mysite/enco%20ded returns '/enco%20ded'
- http://localhost/mysite/about?var=1 returns '/about'
Return Value
string | The raw path (i.e. not urldecoded) |
string getBasePath()
Returns the root path from which this request is executed.
Suppose that an index.php file instantiates this request object:
- http://localhost/index.php returns an empty string
- http://localhost/index.php/page returns an empty string
- http://localhost/web/index.php returns '/web'
- http://localhost/we%20b/index.php returns '/we%20b'
Return Value
string | The raw path (i.e. not urldecoded) |
string getBaseUrl()
Returns the root URL from which this request is executed.
The base URL never ends with a /.
This is similar to getBasePath(), except that it also includes the script filename (e.g. index.php) if one exists.
Return Value
string | The raw URL (i.e. not urldecoded) |
string getScheme()
Gets the request's scheme.
Return Value
string |
int|string getPort()
Returns the port on which the request is made.
This method can read the client port from the "X-Forwarded-Port" header when trusted proxies were set via "setTrustedProxies()".
The "X-Forwarded-Port" header must contain the client port.
Return Value
int|string | can be a string if fetched from the server bag |
string|null getUser()
Returns the user.
Return Value
string|null |
string|null getPassword()
Returns the password.
Return Value
string|null |
string getUserInfo()

The port name will be appended to the host if it's non-standard.
Return Value
string |
string getRequestUri()
Returns the requested URI (path and query string).
Return Value
string | The raw URI (i.e. not URI decoded) |
string getSchemeAndHttpHost()
Gets the scheme and HTTP host.
If the URL was called with basic authentication, the user and the password are not added to the generated string.
Return Value
string | The scheme and HTTP host |
string getUri()
Generates a normalized URI (URL) for the Request.
Return Value
string | A normalized URI (URL) for the Request |
See also
getQueryString() |
string getUriForPath(string $path)
Generates a normalized URI for the given path.
Parameters
string | $path | A path to use instead of the current one |
Return Value
string | The normalized URI for the path |
string getRelativeUriForPath(string $path)
Returns the path as relative reference from the current Request path.
Only the URIs path component (no schema, host etc.) is relevant and must be given. Both paths must be absolute and not contain relative parts. Relative URLs from one resource to another are useful when generating self-contained downloadable document archives. Furthermore, they can be used to reduce the link size in documents.
Example target paths, given a base path of "/a/b/c/d": - "/a/b/c/d" -> "" - "/a/b/c/" -> "./" - "/a/b/" -> "../" - "/a/b/c/other" -> "other" - "/a/x/y" -> "../../x/y"
Parameters
string | $path | The target path |
Return Value
string | The relative target path |
string|null getQueryString()

string|null | A normalized query string for the Request |
bool isSecure()
Checks whether the request is secure or not.
This method can read the client protocol from the "X-Forwarded-Proto" header when trusted proxies were set via "setTrustedProxies()".
The "X-Forwarded-Proto" header must contain the protocol: "https" or "http".
Return Value
bool |
string getHost()
