需要使用的技术栈：脚手架、vuex、router以及element-ui和axios

不会安装的可以看一下之前的安装教学demo1需要安装的技术栈

先看实现效果：

获取数据的话可以找我要一下本地数据的接口，如果想自己用mokejs模拟数据的话也可以 。不会模拟的话可以参考这篇mokejs模拟数据

接下来正式写demo

先写登录页面样式

Login.vue页面

<template>
  <div class="home">
    <div class="homebox" v-loading="loading">
      <h3>KGC后台管理系统</h3>
      <el-input
        class="input"
        v-model="username"
        style="width: 500px"
        placeholder="用户名"
      ></el-input>
      <el-input
        class="input"
        placeholder="密码"
        style="width: 500px"
        v-model="password"
        show-password
      ></el-input>
      <el-button
        type="primary"
        size="medium "
        @click="login"
        style="width: 500px"
        >登陆</el-button
      >
    </div>
  </div>
</template>
<script>
export default {
  name: "Login",
  data() {
    return {
      username: "admin",
      password: 123,
      loading: false,
    };
  },
  methods: {
    login() {
      
    },
  },
};
</script>
<style>
body {
  background-color: rgb(238, 243, 250);
}
.homebox {
  text-align: center;
  position: absolute;
  top: 50%;
  left: 50%;
  margin-top: -150px;
  margin-left: -300px;
  width: 600px;
  height: 300px;
  background-color: rgb(255, 255, 255);
}
h3 {
  padding-top: 20px;
}
.input {
  margin-bottom: 20px;
}
</style>

 之后可以先写后台系统页面

<template>
  <div class="admin">
    <div class="header">
      <router-view name="Header"></router-view>
    </div>
    <router-view></router-view>
    <el-tabs
      v-model="activeName"
      :tab-position="tabPosition"
      type="card"
      @tab-click="handleClick"
    >
      <el-tab-pane label="用户管理" name="first">
        <template>
          <el-table :data="tableData" style="width: 100%">
            <el-table-column prop="id" label="编号"> </el-table-column>
            <el-table-column prop="name" label="用户名"> </el-table-column>
            <el-table-column prop="role" label="角色"> </el-table-column>
            <el-table-column prop="phone" label="手机号码"> </el-table-column>
            <el-table-column prop="email" label="邮箱"> </el-table-column>
            <el-table-column label="操作">
              <template v-slot="scope">
                <el-button
                  size="mini"
                  type="danger"
                  @click="deleteData(scope.$index, tableData)"
                  >删除</el-button
                >
              </template>
            </el-table-column>
          </el-table>
        </template>
      </el-tab-pane>
      <!-- {{banner[0].id}} -->
      <el-tab-pane label="商品管理" name="second">
        <template>
          <el-table :data="table" style="width: 80%">
            <el-table-column prop="id" label="编号"> </el-table-column>
            <el-table-column prop="name" label="商品名称"> </el-table-column>
            <el-table-column prop="price" label="单价"> </el-table-column>
            <el-table-column prop="number" label="库存"> </el-table-column>
          </el-table>
        </template>
      </el-tab-pane>
    </el-tabs>
  </div>
</template>

<script>
// import axios from "axios";
import { mapState } from "vuex";
export default {
  name: "Admin",
  computed: {
    ...mapState(["tableData"]),
    ...mapState(["table"]),
  },
  components: {
    Header: "Header",
  },
  data() {
    return {
      tabPosition: "left",
      activeName: "first",
    };
  },

  methods: {
    handleClick(tab, event) {
      console.log(tab, event);
    },
  },
};
</script>

<style scoped>
* {
  margin: 0;
  padding: 0;
}
.header {
  width: 100%;
  background-color: #00bfff;
}
</style>

头部样式：

<template>
  <div class="header">
    <div class="header-left">
      <div class="left">KGC后台管理系统</div>
    </div>
    <div class="header-right">
      <div class="header-right__logout">
        <el-button type="danger" size="20" @click="logout">退出</el-button>
      </div>
      <div class="header-right__info">
        <div class="right">{{ user.name }}</div>
      </div>
    </div>
  </div>
</template>

<script>
import { mapState } from "vuex";
export default {
  name: "Header",
  data() {
    return {};
  },
  mounted() {},
  methods: {
    logout() {
      this.$confirm("您确定要退出吗, 是否继续?", "提示", {
        confirmButtonText: "确定",
        cancelButtonText: "取消",
        type: "warning",
      })
        .then(() => {
          window.sessionStorage.removeItem("LeftList");
          this.$message({
            message: "你已经退出登陆！请重新登录账号",
            type: "warning",
          });
          this.$router.push({ path: "/login" });
        })
        .catch((err) => err);
    },
  },
  computed: {
    ...mapState(["user"]),
  },
};
</script>

<style scoped>
.header {
  height: 50px;
  line-height: 50px;
  background-color: rgb(73, 80, 96);
  padding: 0 50px;
  color: #fff;
  box-shadow: 5px -2px 5px #00bfff;
}
.left {
  color: #fff;
  float: left;
}
.header-right__info {
  float: right;
  margin: 0 20px;
}
.header-right__logout {
  float: right;
}
</style>

 把normal.css在app.vue 中或者在main中引入即可 

接下来就可以现在这个页面中尝试获取数据

使用JSON-data数据

安装：npm install -g json-server

 

 使用vuex获取数据

 mounted() {
    this.$axios.get("/users").then((res) => {
      const home = res.data;
      this.$store.commit("addrecord", home);
      console.log(home);
    });
  },

 

 用同样的方法引入商品管理

这里想直接在点击登录页面后进入此网页

就在登录按钮中获取数据

login() {
      this.$axios.get("/users").then((res) => {
        const home = res.data;
        this.$store.commit("addrecord", home);
        console.log(home);
      })
    },

 当我们点击登陆时会看到获取到的数据

 这时可以设置一个延迟两秒钟的定时器用来加载页面，加载完毕后结束

 login() {
      this.$axios.get("/users").then((res) => {
        const home = res.data;
        this.$store.commit("addrecord", home);
        console.log(home);
        // 开启加载动画
        this.loading = true;
        setTimeout(() => {
          this.loading = false;
          this.$message({
            message: "恭喜你登陆成功，欢迎来到User页面",
            type: "success",
          });
        }, 2000);
      });
    },

效果如下：

通过循环开始遍历数据中存在的账号以及密码

 login() {
      this.$axios.get("/users").then((res) => {
        const home = res.data;
        this.$store.commit("addrecord", home);
        console.log(home);
        // 开启加载动画
        this.loading = true;
        setTimeout(() => {
    // 遍历账号以及密码
          for (let i = 0; i < home.length; i++) {
            console.log(home[i].name);
            console.log(home[i].pwd);
          }
          this.loading = false;
          this.$message({
            message: "恭喜你登陆成功，欢迎来到User页面",
            type: "success",
          });
        }, 2000);
      });
    },

效果如下： 

 

因为密码都是123所以这里就不获取他的密码了，直接判断他为123

if (this.username == home[i].name && this.password == 123) {
              // 如果为真，那么就让登陆通过
              this.loading = false;
              this.$message({
                message: "恭喜你登陆成功，欢迎来到User页面",
                type: "success",
              });
            }

再次判断如果账号为超级管理员，那么就进入超级管理员页面，如果账号密码不是超级管理员，就进入普通的用户页面，否则不允许进入页面

User页面如下：

<template>
  <div class="admin">
    <div class="header">
      <router-view name="Header"></router-view>
    </div>
    <router-view></router-view>
    <el-tabs
      v-model="activeName"
      :tab-position="tabPosition"
      type="card"
      @tab-click="handleClick"
    >
      <!-- {{banner[0].id}} -->
      <el-tab-pane v-if="show" label="商品管理" name="first">
        <template>
          <el-table :data="table" style="width: 90%">
            <el-table-column prop="id" label="编号"> </el-table-column>
            <el-table-column prop="name" label="商品名称"> </el-table-column>
            <el-table-column prop="price" label="单价"> </el-table-column>
            <el-table-column prop="number" label="库存"> </el-table-column>
          </el-table>
        </template>
      </el-tab-pane>
    </el-tabs>
  </div>
</template>

<script>
// import axios from "axios";
import { mapState } from "vuex";
export default {
  name: "Admin",
  computed: {
    ...mapState(["table"]),
  },
  components: {
    Header: "Header",
  },
  data() {
    return {
      tabPosition: "left",
      activeName: "first",
      content: "",
      banner: "",
      body: "",
      show: true,
    };
  },

  mounted() {
    this.$axios.get("/goods").then((resf) => {
      const user = resf.data;
      console.log(user);
      this.$store.commit("record", user);
      for (let i = 0; i < user.length; i++) {}
    });
  },

  methods: {
    handleClick(tab, event) {
      console.log(tab, event);
    },
  },
};
</script>

<style scoped>
* {
  margin: 0;
  padding: 0;
}
.header {
  width: 100%;
  background-color: #00bfff;
}
</style>

在router里写入以下代码：（加入一个守卫导航防止跳转）

router.beforeEach((to, from, next) => {
  if (to.path == '/login') {
    next()
  } else {
    let token = window.sessionStorage.getItem('name')
    if (!token) {
      next('/login')
    } else {
      next()
    }
  }
})
const originalPush = VueRouter.prototype.push
// 重写了原型上的push方法，统一的处理了错误信息
VueRouter.prototype.push = function push(location) {
  return originalPush.call(this, location).catch(err => err)
}
