Grails Cookie Plugin

Build Status

This plugin makes dealing with cookies easy. Provides an injectable service and tag to easily get, set, and delete cookies with one line.

It's RFC 6265 compliant.

Installation

To install the cookie plug-in just add to build.gradle:

    
    implementation 'org.grails.plugins:cookie:2.0.5'

Configuration

You can configure in Config.groovy or application.yml how long the default cookie age will be (in seconds) when not explicitly supplied while setting a cookie.

grails.plugins.cookie.cookieage.default = 86400 // if not specified default in code is 30 days

Usage

You have two ways to work with cookies:

  • The cookie plug-in extends the request and response objects found in controllers, filters, etc to allow the following.
  • The cookie plug-in provides a CookieService that can be used anywhere in your Grails application.

Example of setting a new cookie:

// This sets a cookie with the name `username` to the value `cookieUser123` with a expiration set to a week, defined in seconds
response.setCookie('username', 'cookieUser123', 604800)
// will use default age from Config (or 30 days if not defined)
response.setCookie('username', 'cookieUser123')

// using service
def cookieService // define field for DI
...
cookieService.setCookie('username', 'cookieUser123', 604800)

To get the cookie value:

request.getCookie('username') // returns 'cookieUser123'

// using service
def cookieService // define field for DI
...
cookieService.getCookie('username') // returns 'cookieUser123'

To delete the cookie (actually it set new expired cookie with same name):

response.deleteCookie('username') // deletes the 'username' cookie
// using service
def cookieService // define field for DI
...
cookieService.deleteCookie('username')

All this methods has other signatures and you can find all of them in CookieService JavaDoc's.

You can check out Demo project and also you can find details of implementation in CookieRequestSpec and CookieResponseSpec.

Configuration

You can configure default values of attributes in Config.groovy.

Default Max Age

Default expiration age for cookie in seconds. Max-Age attribute, integer.

If it has value -1 cookie will not stored and removed after browser close.

If it has null value or unset, will be used 30 days, i.e. 2592000 seconds.

Can't has value 0, because it means that cookie should be removed.

grails.plugins.cookie.cookieage.default = 360 * 24 * 60 * 60

Default Path

Default path for cookie selection strategy, string.

  • 'context' - web app context path, i.e. grails.app.context option in Config.groovy
  • 'root' - root of server, i.e. '/'
  • 'current' - current directory, i.e. controller name

If default path is null or unset, it will be used 'context' strategy

grails.plugins.cookie.path.defaultStrategy = 'context'

Default Secure

Default secure cookie param. Secure cookie available only for HTTPS connections. Secure attribute, boolean. If default secure is null or unset, it will set all new cookies as secure if current connection is secure

grails.plugins.cookie.secure.default = null

Default HTTP Only

Default HTTP Only param that denies accessing to JavaScript's document.cookie.

If null or unset will be true

grails.plugins.cookie.httpOnly.default = true

You can find details of implementation in CookieServiceDefaultsSpec.

External Config

If you use property files to inject values to plugins at runtime. This is now supported as of version 1.0.2. This means that inside your external foo.properties file you can specify the following.

grails.plugins.cookie.httpOnly.default=true

The string value will correctly be treated as a boolean.

  • #22 Support of cookie attributes
  • #10 Improved delete cookie method. Method delete cookie now can takes a domain name

v0.3

Source

In the v0.3 release a big issue was fixed that now sets the cookie's path to the root / context. Otherwise it was setting the path to the same as the controller/service that triggered it. Most users I believe will want this behavior. If setting the path is desired, that can be accommodated. Please contact me or do a pull request if you'd like that.
