https://blog.csdn.net/maidu_xbd/article/details/87943243已经搭建好了vue开发环境，在本博客中，来介绍些结合element-ui实现登录注册界面。界面效果展示如下图：

实现的功能包括：

首先安装：通过npm方式进行安装（更好地和 webpack 打包工具配合使用），其他使用方式可以看官网（http://element-cn.eleme.io/#/zh-CN/component/installation）。

npm i element-ui -S

安装axios：【npm install axios --save-dev】

项目目录如下图：

路由配置：【router】->【index.js】：实现路由的配置

import Vue from 'vue'
import Router from 'vue-router'
import Personal from '@/components/Personal'
import Login from '@/components/Login'
import Register from '@/components/Register'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/personal',
      name: 'Personal',
      component: Personal
    },
    {
      path: '/',
      name: 'Login',
      component: Login
    },
    {
      path: '/register',
      name: 'Register',
      component: Register
    }
  ],
  mode: "history"
})

以上三个路由path分别对应于登录成功后的跳转页面首页【/personal】，登录页面，注册页面。

项目核心文件【main.js】：实例化vue对象，引入需要使用的工具，如axios，element-ui等

import Vue from 'vue'
import App from './App'
import router from './router'
import axios from 'axios'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.use(ElementUI)
//全局配置
Vue.prototype.$axios = axios
Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  components: { App },
  template: '<App/>'
})

登录界面【Login.vue】：进行了简单的非空校验；通过axios进行http请求，实现向后台提交登录数据，根据后台反馈的status判断信息的正确与否，正确则跳转到首页【/personal】

<template>
  <div class="login" clearfix>
    <div class="login-wrap">
      <el-row type="flex" justify="center">
        <el-form ref="loginForm" :model="user" :rules="rules" status-icon label-width="80px">
          <h3>登录</h3>
          <hr>
          <el-form-item prop="username" label="用户名">
            <el-input v-model="user.username" placeholder="请输入用户名" prefix-icon></el-input>
          </el-form-item>
          <el-form-item id="password" prop="password" label="密码">
            <el-input v-model="user.password" show-password placeholder="请输入密码"></el-input>
          </el-form-item>
          <router-link to="/">找回密码</router-link>
          <router-link to="/register">注册账号</router-link>
          <el-form-item>
            <el-button type="primary" icon="el-icon-upload" @click="doLogin()">登 录</el-button>
          </el-form-item>
        </el-form>
      </el-row>
    </div>
  </div>
</template>

<script>
import axios from "axios";
export default {
  name: "login",
  data() {
    return {
      user: {
        username: "",
        password: ""
      }
      // rules: {
      //   username: [{ message: "用户名不能为空", trigger: "blur" }],
      //   password: [{ message: "密码不能为空", trigger: "blur" }]
      // }
    };
  },
  created() {},
  methods: {
    doLogin() {
      if (!this.user.username) {
        this.$message.error("请输入用户名！");
        return;
      } else if (!this.user.password) {
        this.$message.error("请输入密码！");
        return;
      } else {
        //校验用户名和密码是否正确;
        // this.$router.push({ path: "/personal" });
        axios
          .post("/login/", {
            name: this.user.username,
            password: this.user.password
          })
          .then(res => {
            // console.log("输出response.data.status", res.data.status);
            if (res.data.status === 200) {
              this.$router.push({ path: "/personal" });
            } else {
              alert("您输入的用户名或密码错误！");
            }
          });
      }
    }
  }
};
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.login {
  width: 100%;
  height: 740px;
  background: url("../assets/images/bg1.png") no-repeat;
  background-size: cover;
  overflow: hidden;
}
.login-wrap {
  background: url("../assets/images/login_bg.png") no-repeat;
  background-size: cover;
  width: 400px;
  height: 300px;
  margin: 215px auto;
  overflow: hidden;
  padding-top: 10px;
  line-height: 40px;
}
#password {
  margin-bottom: 5px;
}
h3 {
  color: #0babeab8;
  font-size: 24px;
}
hr {
  background-color: #444;
  margin: 20px auto;
}
a {
  text-decoration: none;
  color: #aaa;
  font-size: 15px;
}
a:hover {
  color: coral;
}
.el-button {
  width: 80%;
  margin-left: -50px;
}
</style>

注册界面【Register.vue】：注册界面与登录界面大部分类似，直接copy登录界面进行修改即可。实现输入邮箱规则校验，注册成功后跳转到登录界面

<template>
  <div class="login clearfix">
    <div class="login-wrap">
      <el-row type="flex" justify="center">
        <el-form ref="loginForm" :model="user" status-icon label-width="80px">
          <h3>注册</h3>
          <hr>
          <el-form-item prop="username" label="用户名">
            <el-input v-model="user.username" placeholder="请输入用户名"></el-input>
          </el-form-item>
          <el-form-item prop="email" label="邮箱">
            <el-input v-model="user.email" placeholder="请输入邮箱"></el-input>
          </el-form-item>
          <el-form-item prop="password" label="设置密码">
            <el-input v-model="user.password" show-password placeholder="请输入密码"></el-input>
          </el-form-item>
          <el-form-item>
            <el-button type="primary" icon @click="doRegister()">注册账号</el-button>
          </el-form-item>
        </el-form>
      </el-row>
    </div>
  </div>
</template>

<script>
import axios from "axios";
export default {
  name: "login",
  data() {
    return {
      user: {
        username: "",
        email: "",
        password: ""
      },
      rules: {
        username: [{ message: "用户名不能为空", trigger: "blur" }],
        email: [{ message: "邮箱不能为空", trigger: "blur" }],
        password: [{ message: "密码不能为空", trigger: "blur" }]
      }
    };
  },
  created() {
    // console.log($);
    // console.log("1111");
  },
  methods: {
    doRegister() {
      if (!this.user.username) {
        this.$message.error("请输入用户名！");
        return;
      } else if (!this.user.email) {
        this.$message.error("请输入邮箱！");
        return;
      } else if (this.user.email != null) {
        var reg = /^[A-Za-z0-9\u4e00-\u9fa5]+@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+)+$/;
        if (!reg.test(this.user.email)) {
          this.$message.error("请输入有效的邮箱！");
        } else if (!this.user.password) {
          this.$message.error("请输入密码！");
          return;
        } else {
          // this.$router.push({ path: "/" }); //无需向后台提交数据，方便前台调试
          axios
            .post("/register/", {
              name: this.user.username,
              email: this.user.email,
              password: this.user.password
            })
            .then(res => {
              // console.log("输出response.data", res.data);
              // console.log("输出response.data.status", res.data.status);
              if (res.data.status === 200) {
                this.$router.push({ path: "/" });
              } else {
                alert("您输入的用户名已存在！");
              }
            });
        }
      }
    }
  }
};
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.login {
  width: 100%;
  height: 740px;
  background: url("../assets/images/bg1.png") no-repeat;
  background-size: cover;
  overflow: hidden;
}
.login-wrap {
  background: url("../assets/images/login_bg.png") no-repeat;
  background-size: cover;
  width: 400px;
  height: 300px;
  margin: 215px auto;
  overflow: hidden;
  padding-top: 10px;
  line-height: 20px;
}

h3 {
  color: #0babeab8;
  font-size: 24px;
}
hr {
  background-color: #444;
  margin: 20px auto;
}

.el-button {
  width: 80%;
  margin-left: -50px;
}
</style>

挺简单的，就不分析代码了。
