Fourteen_图形认证_登录注册
2. 用户的登录认证
前端首页实现登录状态的判断
# Header.vue组件代码： <script> export default { name: "Header", data(){ return { // 设置一个登录标识，表示是否登录 token: sessionStorage.token || localStorage.token, user_name: sessionStorage.user_name || localStorage.user_name, user_id: sessionStorage.user_id || localStorage.user_id, nav_list:[], }; }, 。。。 } </script>
头部组件中实现退出登录
实现的思路：头部子组件是通过token值进行判断登录状态，所以当用户点击"退出登录"，则需要移出token的值，并使用elementUI里面的弹窗组件进行提示。
# Header.vue组件代码： <template> <div class="header"> <el-container> <el-header> <el-row> <el-col class="logo" :span="3"> <a href="/"> <img src="@/assets/head-logo.svg" alt=""> </a> </el-col> <el-col class="nav" :span="16"> <el-row> <el-col v-for="nav in nav_list" :span="3"><a :class="check(nav.link)?'current':''" :href="nav.link">{{nav.name}}</a></el-col> </el-row> </el-col> <el-col class="login-bar" :span="5"> <el-row v-if="token"> <el-col class="cart-ico" :span="9"> <router-link to=""> <b class="goods-number">0</b> <img class="cart-icon" src="@/assets/cart.svg" alt=""> <span><router-link to="/cart">购物车</router-link></span> </router-link> </el-col> <el-col class="study" :span="8" :offset="2"><router-link to="">学习中心</router-link></el-col> <el-col class="member" :span="5"> <el-menu class="el-menu-demo" mode="horizontal"> <el-submenu index="2"> <template slot="title"><router-link to=""><img src="@/assets/logo@2x.png" alt=""></router-link></template> <el-menu-item index="2-1">我的账户</el-menu-item> <el-menu-item index="2-2">我的订单</el-menu-item> <el-menu-item index="2-3">我的优惠卷</el-menu-item> <el-menu-item index="2-3"><span @click="logout">退出登录</span></el-menu-item> </el-submenu> </el-menu> </el-col> </el-row> <el-row v-else> <el-col class="cart-ico" :span="9"> <router-link to=""> <img class="cart-icon" src="@/assets/cart.svg" alt=""> <span><router-link to="/cart">购物车</router-link></span> </router-link> </el-col> <el-col :span="10" :offset="5"> <span class="register"> <router-link to="/login">登录</router-link> | <router-link to="/register">注册</router-link> </span> </el-col> </el-row> </el-col> </el-row> </el-header> </el-container> </div> </template> <script> export default { name: "Header", data(){ return { // 设置一个登录标识，表示是否登录 token: sessionStorage.token || localStorage.token, user_name: sessionStorage.user_name || localStorage.user_name, user_id: sessionStorage.user_id || localStorage.user_id, nav_list:[], }; }, created() { // 获取导航 this.$axios.get(this.$settings.Host+"/nav/").then(response=>{ this.nav_list = response.data console.log(this.nav_list) }).catch(error=>{ console.log(error.response) }) }, methods:{ check(link){ return link==window.location.pathname }, logout(){ this.token = false; this.user_id=false; this.user_name=false; sessionStorage.removeItem("token"); sessionStorage.removeItem("user_id"); sessionStorage.removeItem("user_name"); localStorage.removeItem("token"); localStorage.removeItem("user_id"); localStorage.removeItem("user_name"); this.$alert('退出登录成功!', '路飞学城', { confirmButtonText: '确定' }); } } } </script>
注册登录以后，即进入登录后台，选择行为验证。

# 终端安装django-redis。 # 这条不用 pip install django-redis sudo apt-get install redis-server
ps -aux | grep redis # 查看redis的状态
redis-cli # 进入redis
ping # 如果响应pong 即连接成功 sudo vim /etc/redis/redis.conf # 查看数据库接口 # 其中有个POST: 6379 的字节是表明接下来你要调用的post请求端口
# 在settings.py配置中添加一下代码即dev： # 设置redis缓存 CACHES = { # 默认缓存 "default": { "BACKEND": "django_redis.cache.RedisCache", # 项目上线时,需要调整这里的路径 "LOCATION": "redis://127.0.0.1:6379/0", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } }, # 提供给xadmin或者admin的session存储 "session": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://127.0.0.1:6379/1", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } }, # 提供存储短信验证码 "sms_code":{ "BACKEND": "django_redis.cache.RedisCache", "LOCATION": "redis://127.0.0.1:6379/2", "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } } } # 设置xadmin用户登录时,登录信息session保存到redis SESSION_ENGINE = "django.contrib.sessions.backends.cache" SESSION_CACHE_ALIAS = "session"
关于django-redis 的使用，说明文档可见http://django-redis-chs.readthedocs.io/zh_CN/latest/
django-redis提供了get_redis_connection的方法，通过调用get_redis_connection方法传递redis的配置名称可获取到redis的连接对象，通过redis连接对象可以执行redis命令
