Grails用户验证及验证码
下面是控制器
// def scaffold = Sipaccount
//拦截器
def beforeInterceptor = [action:this.&auth, except:["index","list","login","authenticate","logout"]]
//验证码插件
def jcaptchaService
def auth(){
if(!session.user){
//保留认证前的页面
session.originReqParams=params
redirect(controller:"sipaccount",action:"login")
return false
}
}
//认证页面
def login = {}
def authenticate = {
//先检查验证码
if (jcaptchaService.validateResponse("imageCaptcha", session.id, params.captchaResponse)) {
//验证用户
def user = Sipaccount.findByUser_nameAndPassword(params.login, params.password)
if(user){
session.user = user
flash.message = "Hello ${user.user_name}!"
// redirect(controller:"sipaccount", action:"list")
//回到认证前页面
redirect(session.originReqParams)
}else{
//用户验证错误
flash.message = "Sorry, ${params.login}. Please try again."
redirect(action:"login")
}
}else{
//验证码错误
flash.message = "对不起，验证码错误，请重试！"
redirect(action:"login")
}
}
def logout = {
flash.message = "Goodbye ${session.user.name}"
session.user = null
redirect(controller:"Sipaccount", action:"list")
}

验证码插件安装：
grails install-plugin jcaptcha
Config.groovy的配置：
最后加上下面的内容
import java.awt.Font
import java.awt.Color
import com.octo.captcha.service.multitype.GenericManageableCaptchaService
import com.octo.captcha.engine.GenericCaptchaEngine
import com.octo.captcha.image.gimpy.GimpyFactory
import com.octo.captcha.component.word.wordgenerator.RandomWordGenerator
import com.octo.captcha.component.image.wordtoimage.ComposedWordToImage
import com.octo.captcha.component.image.fontgenerator.RandomFontGenerator
import com.octo.captcha.component.image.backgroundgenerator.GradientBackgroundGenerator
import com.octo.captcha.component.image.color.SingleColorGenerator
import com.octo.captcha.component.image.textpaster.NonLinearTextPaster
import com.octo.captcha.service.sound.DefaultManageableSoundCaptchaService
jcaptchas {
imageCaptcha = new GenericManageableCaptchaService(
new GenericCaptchaEngine(
new GimpyFactory(
new RandomWordGenerator(
"abcdefghijklmnopqrstuvwxyz1234567890"
),
new ComposedWordToImage(
new RandomFontGenerator(
20, // min font size
30, // max font size
[new Font("Arial", 0, 10)] as Font[]
),
new GradientBackgroundGenerator(
140, // width
35, // height
new SingleColorGenerator(new Color(0, 60, 0)),
new SingleColorGenerator(new Color(20, 20, 20))
),
new NonLinearTextPaster(
6, // minimal length of text
6, // maximal length of text
new Color(0, 255, 0)
)
)
)
),
180, // minGuarantedStorageDelayInSeconds
180000 // maxCaptchaStoreSize
)
// soundCaptcha = new DefaultManageableSoundCaptchaService()
}
URL Mapping
class UrlMappings {
static mappings = {
"/$controller/$action?/$id?"{
constraints {
// apply constraints here
}
}
// "/"(view:"/index")
//将"/"映射到对应的页面
"/"(controller:"Sipaccount",action:"list")
"500"(view:'/error')
}
}
启动时检查是否有超级用户，没有的话创建：
BootStrap.groovy
class UrlMappings {
import sipaccount.Sipaccount
class BootStrap {
def init = { servletContext ->
if(!Sipaccount.findByUser_name('admin')){
new Sipaccount(user_name:'admin',sip_id:'admin',password:'12345678',user_level:0).save()
}
}
def destroy = {
}
}
