一、登录

1.登录(初始版)

# 登录接口
class Login(APIView):
    def post(self, request):
        response = MyResponse()
        name = request.data.get('name')
        pwd = request.data.get('pwd')
        user = models.UserInfo.objects.filter(name=name, pwd=pwd).first()
        if user:
            import uuid
            token = uuid.uuid4()
            models.UserToken.objects.update_or_create(user=user, defaults={'token': token})
            response.msg = '登录成功'
            response.name = name
            response.token = token
        else:
            response.msg = '用户名或密码不正确'
            response.status = 101
        return Response(response.get_dic)

// main.js
// 1.先把store导入main.js
import store from './store'

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount('#app')


// store.js
// 2.配置全局变量
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
    // state：全局变量
    state: {
        name: '',
        token: '',
    },
    mutations: {
    },
    actions: {}
})


// Login.vue
// 3.使用全局变量
methods: {
    login: function () {
        let _this = this;
        this.$http.request({
            url: _this.$url + '/login/',
            method: 'post',
            data: {'name': _this.name, 'pwd': _this.pwd},
        }).then(function (response) {
            if (response.data.status == 100) {
              //_this.$store.state.变量名
              _this.$store.state.name = response.data.name;
              _this.$store.state.token = response.data.token
              location.href = '/'
            }
        })
    }
},

注：把cookie存在全局变量中，每次新页面会导致全局变量重置，不能永久保存

2.登录(cookie)

import Vue from 'vue'
import Vuex from 'vuex'
import Cookie from 'vue-cookies'
// 安装vue-cookies: npm install vue-cookies
Vue.use(Vuex)

export default new Vuex.Store({
    // state：全局变量
    state: {
        name: Cookie.get('name'),
        token: Cookie.get('token'),
    },
    //mutations：方法
    mutations: {
        login: function (state, response) {
            // 替换全局变量
            state.name = response.name
            state.token = response.token

            // 往cookie中写数据
            Cookie.set('name', response.data.name)
            Cookie.set('token', response.data.token)
        },
        logout: function (state) {
            state.name = '';
            state.token = '';
            Cookie.set('name', '');
            Cookie.set('token', '')
        },

    },
    actions: {}
})

methods: {
    login: function () {
        let _this = this;
        this.$http.request({
            url: _this.$url + '/login/',
            method: 'post',
            data: {'name': _this.name, 'pwd': _this.pwd},
        }).then(function (response) {
            // 调用store.js的方法：
            // _this.$store.commit('方法名','参数')
            if (response.data.status == 100) {
                _this.$store.commit('login', response)
                location.href = '/'
            }
        })
    }
},
