nsICookieService 编辑

netwerk/cookie/public/nsICookieService.idlScriptable Provides methods for setting and getting cookies in the context of a page load. Inherits from: nsISupports Last changed in Gecko 1.9 (Firefox 3)

See nsICookieManager and nsICookieManager2 for methods to manipulate the cookie database directly. This separation of interface is mainly historical.

var cookieSvc = Components.classes["@mozilla.org/cookieService;1"]
                  .getService(Components.interfaces.nsICookieService);

Notifications

This service broadcasts the following notifications when the cookie list is changed, or a cookie is rejected:

Topic	Subject	Data
cookie-changed Broadcast whenever the cookie list changes in some way. There are four possible data strings for this notification; one notification will be broadcast for each change.	Depending on the Data value, either an nsICookie2 interface pointer representing the cookie object that changed, or an nsIArray of nsICookie2 objects.	A keyword indicating what was done to the affected cookie. deleted A cookie was deleted. The subject is the deleted cookie. added A cookie was added. The subject is the added cookie. changed A cookie was changed. The subject is the changed cookie. batch-deleted A set of cookies were deleted as part of a purge operation. This typically happens because they have either expired or because the cookie list has grown too large. The subject is an nsIArray of deleted cookies. cleared The entire cookie list was cleared. The subject is null. reload The entire cookie list was changed, and the observer should reload the list of cookies. The subject is null.
private-cookie-changed Since Firefox 20 (see bugzilla #837091)	Same as cookie-changed, except used in lieu of cookie-changed for private windows.	See cookie-changed.
cookie-rejected Broadcast whenever the user's preferences cause a cookie to be rejected from being set.	An nsIURI interface pointer representing the URI that attempted to set the cookie.	None.

Attributes

Attribute	Type	Description
cookieIconIsVisible	boolean	This attribute really doesn't belong on this interface. CVS blame will tell you why it is here. It remains until we can find a better home for it.

Methods

getCookieString()

Get the complete cookie string associated with the URI.

 string getCookieString(
   in nsIURI aURI,
   in nsIChannel aChannel
 );

Parameters

aURI

The URI of the document for which cookies are being queried.

aChannel

The channel used to load the document. this parameter may be null, but it is strongly recommended that a non-null value be provided to ensure that the cookie privacy preferences are honored.

Return value

Returns the resulting cookie string.

getCookieStringFromHttp()

Get the complete cookie string associated with the URI.

Note: This function is redundant and will most likely be removed in a future revision of this interface. getCookieString() will query the documentURI property off of nsIHttpChannelInternal if supported, so getCookieString() can be used in place of this method.

 string getCookieStringFromHttp(
   in nsIURI aURI,
   in nsIURI aFirstURI,
   in nsIChannel aChannel
 );

Parameters

aURI

The URI of the document for which cookies are being queried.

aFirstURI

The URI that the user originally typed in or clicked on to initiate the load of the document referenced by aURI.

aChannel

The channel used to load the document. this parameter may be null, but it is strongly recommended that a non-null value be provided to ensure that the cookie privacy preferences are honored.

Return value

Returns the resulting cookie string.

setCookieString()

Set the cookie string associated with the URI.

Note: Should be able to allow null aPrompt, since nsIPrompt can be queried from aChannel.

 void setCookieString(
   in nsIURI aURI,
   in nsIPrompt aPrompt,
   in string aCookie,
   in nsIChannel aChannel
 );

Parameters

aURI

The URI of the document for which cookies are being queried.

aPrompt

The prompt to use for all user-level cookie notifications.

aCookie

The cookie string to set.

aChannel

The channel used to load the document. this parameter may be null, but it is strongly recommended that a non-null value be provided to ensure that the cookie privacy preferences are honored.

setCookieStringFromHttp()

Set the cookie string and expires associated with the URI.

Note: This function is redundant and will most likely be removed in a future revision of this interface. setCookieString() will query the documentURI property off of nsIHttpChannelInternal if supported, and setCookieString() could also query the Date header from the channel if aChannel supports nsIHttpChannel.

 void setCookieStringFromHttp(
   in nsIURI aURI,
   in nsIURI aFirstURI,
   in nsIPrompt aPrompt,
   in string aCookie,
   in string aServerTime,
   in nsIChannel aChannel
 );

Parameters

aURI

The URI of the document for which cookies are being queried.

aFirstURI

The URI that the user originally typed in or clicked on to initiate the load of the document referenced by aURI.

aPrompt

The prompt to use for all user-level cookie notifications.

aCookie

The cookie string to set.

aServerTime

The expiry information of the cookie (the Date header from the HTTP response).

aChannel

The channel used to load the document. this parameter may be null, but it is strongly recommended that a non-null value be provided to ensure that the cookie privacy preferences are honored.
