Detailed Description

The PySide.QtNetwork.QNetworkCookie class holds one network cookie.

Cookies are small bits of information that stateless protocols like HTTP use to maintain some persistent information across requests.

A cookie is set by a remote server when it replies to a request and it expects the same cookie to be sent back when further requests are sent.

PySide.QtNetwork.QNetworkCookie holds one such cookie as received from the network. A cookie has a name and a value, but those are opaque to the application (that is, the information stored in them has no meaning to the application). A cookie has an associated path name and domain, which indicate when the cookie should be sent again to the server.

A cookie can also have an expiration date, indicating its validity. If the expiration date is not present, the cookie is considered a “session cookie” and should be discarded when the application exits (or when its concept of session is over).

PySide.QtNetwork.QNetworkCookie provides a way of parsing a cookie from the HTTP header format using the QNetworkCookie.parseCookies() function. However, when received in a PySide.QtNetwork.QNetworkReply , the cookie is already parsed.

This class implements cookies as described by the initial cookie specification by Netscape , which is somewhat similar to the RFC 2109 specification, plus the “HttpOnly” extension . The more recent RFC 2965 specification (which uses the Set-Cookie2 header) is not supported.

class PySide.QtNetwork.QNetworkCookie([name=QByteArray()[, value=QByteArray()]])
class PySide.QtNetwork.QNetworkCookie(other)

Create a new PySide.QtNetwork.QNetworkCookie object, initializing the cookie name to name and its value to value .

A cookie is only valid if it has a name. However, the value is opaque to the application and being empty may have significance to the remote server.

Creates a new PySide.QtNetwork.QNetworkCookie object by copying the contents of other .


This enum is used with the PySide.QtNetwork.QNetworkCookie.toRawForm() function to declare which form of a cookie shall be returned.

Constant Description
QNetworkCookie.NameAndValueOnly makes PySide.QtNetwork.QNetworkCookie.toRawForm() return only the “NAME=VALUE” part of the cookie, as suitable for sending back to a server in a client request’s “Cookie:” header. Multiple cookies are separated by a semi-colon in the “Cookie:” header field.
QNetworkCookie.Full makes PySide.QtNetwork.QNetworkCookie.toRawForm() return the full cookie contents, as suitable for sending to a client in a server’s “Set-Cookie:” header.

Note that only the Full form of the cookie can be parsed back into its original contents.

Return type:unicode

Returns the domain this cookie is associated with. This corresponds to the “domain” field of the cookie string.

Note that the domain here may start with a dot, which is not a valid hostname. However, it means this cookie matches all hostnames ending with that domain name.

Return type:PySide.QtCore.QDateTime

Returns the expiration date for this cookie. If this cookie is a session cookie, the PySide.QtCore.QDateTime returned will not be valid. If the date is in the past, this cookie has already expired and should not be sent again back to a remote server.

The expiration date corresponds to the parameters of the “expires” entry in the cookie string.

Return type:PySide.QtCore.bool

Returns true if the “HttpOnly” flag is enabled for this cookie.

A cookie that is “HttpOnly” is only set and retrieved by the network requests and replies; i.e., the HTTP protocol. It is not accessible from scripts running on browsers.

Return type:PySide.QtCore.bool

Returns true if the “secure” option was specified in the cookie string, false otherwise.

Secure cookies may contain private information and should not be resent over unencrypted connections.

Return type:PySide.QtCore.bool

Returns true if this cookie is a session cookie. A session cookie is a cookie which has no expiration date, which means it should be discarded when the application’s concept of session is over (usually, when the application exits).

Return type:PySide.QtCore.QByteArray

Returns the name of this cookie. The only mandatory field of a cookie is its name, without which it is not considered valid.

Return type:PySide.QtCore.bool

Returns true if this cookie is not equal to other .

Return type:PySide.QtCore.bool

Returns true if this cookie is equal to other . This function only returns true if all fields of the cookie are the same.

However, in some contexts, two cookies of the same name could be considered equal.

static PySide.QtNetwork.QNetworkCookie.parseCookies(cookieString)
Return type:

Parses the cookie string cookieString as received from a server response in the “Set-Cookie:” header. If there’s a parsing error, this function returns an empty list.

Since the HTTP header can set more than one cookie at the same time, this function returns a QList < PySide.QtNetwork.QNetworkCookie >, one for each cookie that is parsed.

Return type:unicode

Returns the path associated with this cookie. This corresponds to the “path” field of the cookie string.

Parameters:domain – unicode

Sets the domain associated with this cookie to be domain .


Sets the expiration date of this cookie to date . Setting an invalid expiration date to this cookie will mean it’s a session cookie.


Sets this cookie’s “HttpOnly” flag to enable .


Sets the name of this cookie to be cookieName . Note that setting a cookie name to an empty PySide.QtCore.QByteArray will make this cookie invalid.

Parameters:path – unicode

Sets the path associated with this cookie to be path .


Sets the secure flag of this cookie to enable .

Secure cookies may contain private information and should not be resent over unencrypted connections.


Sets the value of this cookie to be value .

Return type:PySide.QtCore.QByteArray

Returns the raw form of this PySide.QtNetwork.QNetworkCookie . The PySide.QtCore.QByteArray returned by this function is suitable for an HTTP header, either in a server response (the Set-Cookie header) or the client request (the Cookie header). You can choose from one of two formats, using form .

Return type:PySide.QtCore.QByteArray

Returns this cookies value, as specified in the cookie string. Note that a cookie is still valid if its value is empty.

Cookie name-value pairs are considered opaque to the application: that is, their values don’t mean anything.
