1. 安装Vue脚手架

npm create vue@latest

2. 引入Element Plus

1. 安装Element Plus

npm install element-plus --save

2. 完整引入

// main.ts

import { createApp } from 'vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'

const app = createApp(App)

app.use(ElementPlus)
app.mount('#app')

3. 引入路由

1. 安装Vue Router

npm install vue-router@next

2. 创建Vue Router实例

在src下创建router文件夹，在文件夹下创建index.ts文件：

// index.ts

import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router';
import Home from './components/Home.vue';
import About from './components/About.vue';

const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    component: Home,
  },
  {
    path: '/about',
    component: About,
  },
];

const router = createRouter({
  history: createWebHistory(),
  routes,
});

export default router;

3. 将Vue Router实例挂载到Vue实例中

// main.ts

import { createApp } from 'vue';
import App from './App.vue';
import router from './router';

const app = createApp(App);

app.use(router);

app.mount('#app');

4. 在Vue应用程序中使用Vue Router

// App.vue

<template>
  <div id="app">
    <router-view></router-view>
  </div>
</template>

<script lang="ts">
import { defineComponent } from 'vue';

export default defineComponent({
  name: 'App',
});
</script>

4. 引入axios

npm install axios

5. 配置代理服务器

在vite.config.ts中配置：

import { defineConfig } from 'vite';
import vue from '@vitejs/plugin-vue';
import vueJsx from '@vitejs/plugin-vue-jsx';

// https://vitejs.dev/config/
export default defineConfig({
    plugins: [vue(), vueJsx()],
    resolve: {
        alias: {
            '@': '/src',
        },
    },
    server: {
        proxy: {
            '/api': {
                target: 'http://localhost:3000',
                changeOrigin: true,
                rewrite: (path) => path.replace(/^\/api/, ''),
            },
        },
    },
});

6. 编写登录组件

在src/views文件夹下创建Login.vue组件

// Login.vue

<template>
  <el-form ref="ruleFormRef" :model="ruleForm" :rules="rules" label-width="120px" class="demo-ruleForm" :size="formSize"
    status-icon>
    <el-form-item label="账号" prop="name">
      <el-input v-model="ruleForm.name" />
    </el-form-item>
    <el-form-item label="密码" prop="password">
      <el-input v-model="ruleForm.password" type="password" />
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm(ruleFormRef)">
        登录
      </el-button>
      <el-button @click="resetForm(ruleFormRef)">重置</el-button>
      <el-button @click="goRegister()">注册</el-button>
    </el-form-item>
  </el-form>
</template>
<script setup lang="ts">
import { reactive, ref } from 'vue';
import { ElMessage, type FormInstance, type FormRules } from 'element-plus';
import axios from 'axios'
import router from '@/router';

interface RuleForm {
  name: string
  password: string
}

const formSize = ref('default')
const ruleFormRef = ref<FormInstance>()
const ruleForm = reactive<RuleForm>({
  name: '',
  password: '',
})

const rules = reactive<FormRules<RuleForm>>({
  name: [
    { required: true, message: '请输入账号', trigger: 'blur' },
  ],
  password: [
    { required: true, message: '请输入密码', trigger: 'blur' },
  ],
})

const submitForm = async (formEl: FormInstance | undefined) => {
  if (!formEl) return
  await formEl.validate(async (valid, fields) => {
    if (valid) {
      try {
        // 使用axios发送网络请求
        const res = await axios.post('/api/auth/login', {
          name: ruleForm.name,
          password: ruleForm.password,
        })

        const token = res.data.access_token;
        ElMessage({
          message: '登录成功~',
          type: 'success'
        })
        localStorage.setItem('token', token);
        router.push('/');
      }
      catch (error: any) {
        if (error.response) {
          const res = error.response.data.message instanceof Array ? error.response.data.message.join('') : error.response.data.message;
          ElMessage({
            message: res,
            type: 'error'
          })
        }
      }
    } else {
      console.log('error submit!', fields)
    }
  })
}

const resetForm = (formEl: FormInstance | undefined) => {
  if (!formEl) return
  formEl.resetFields()
}

const goRegister = () => {
  router.push('/register');
}
</script>
<style scoped></style>

登录成功后会保存token

7. 编写注册组件

在src/views文件夹下创建Register.vue组件

// Register.vue

<template>
  <el-form ref="ruleFormRef" :model="ruleForm" :rules="rules" label-width="120px" class="demo-ruleForm" :size="formSize"
    status-icon>
    <el-form-item label="账号" prop="name">
      <el-input v-model="ruleForm.name" />
    </el-form-item>
    <el-form-item label="密码" prop="password">
      <el-input v-model="ruleForm.password" type="password" />
    </el-form-item>
    <el-form-item label="确认密码" prop="password_confirm">
      <el-input v-model="ruleForm.password_confirm" type="password" />
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm(ruleFormRef)">
        注册
      </el-button>
      <el-button @click="resetForm(ruleFormRef)">重置</el-button>
      <el-button @click="goLogin()">登录</el-button>
    </el-form-item>
  </el-form>
</template>
<script setup lang="ts">
import { reactive, ref } from 'vue';
import { ElMessage, type FormInstance, type FormRules } from 'element-plus';
import axios from 'axios'
import router from '@/router';

interface RuleForm {
  name: string
  password: string
  password_confirm: string
}

const formSize = ref('default')
const ruleFormRef = ref<FormInstance>()
const ruleForm = reactive<RuleForm>({
  name: '',
  password: '',
  password_confirm: '',
})

const validatePass = (rule: any, value: any, callback: any) => {
  if (value === '') {
    callback(new Error('Please input the password'))
  } else {
    if (ruleForm.password_confirm !== '') {
      if (!ruleFormRef.value) return
      ruleFormRef.value.validateField('password_confirm', () => null)
    }
    callback()
  }
}
const validatePass2 = (rule: any, value: any, callback: any) => {
  if (value === '') {
    callback(new Error('请再次输入密码'))
  } else if (value !== ruleForm.password) {
    callback(new Error("两次输入的密码不一致！"))
  } else {
    callback()
  }
}

const rules = reactive<FormRules<RuleForm>>({
  name: [
    { required: true, message: '请输入账号', trigger: 'blur' },
  ],
  password: [
    { required: true, message: '请输入密码', trigger: 'blur' },
    { validator: validatePass, trigger: 'blur' }
  ],
  password_confirm: [{ required: true, message: '请再次输入密码', trigger: 'blur' }, { validator: validatePass2, trigger: 'blur' }],
})

const submitForm = async (formEl: FormInstance | undefined) => {
  if (!formEl) return
  await formEl.validate(async (valid, fields) => {
    if (valid) {
      try {
        // 使用axios发送网络请求
        const res = await axios.post('/api/auth/register', {
          name: ruleForm.name,
          password: ruleForm.password,
          password_confirm: ruleForm.password_confirm,
        })
        ElMessage({
          message: '注册成功~',
          type: 'success'
        })
        router.push('/login');
      }
      catch (error: any) {
        if (error.response) {
          const res = error.response.data.message instanceof Array ? error.response.data.message.join('') : error.response.data.message;
          ElMessage({
            message: res,
            type: 'error'
          })
        }
      }
    } else {
      console.log('error submit!', fields)
    }
  })
}

const resetForm = (formEl: FormInstance | undefined) => {
  if (!formEl) return
  formEl.resetFields()
}

const goLogin = () => {
  router.push('/login');
}
</script>
<style scoped></style>

8. 配置导航守卫

// src/router/index.ts

import LoginVue from '@/views/Login.vue';
import RegisterVue from '@/views/Register.vue';
import { createRouter, createWebHistory } from 'vue-router';

// 创建路由实例
const router = createRouter({
    history: createWebHistory(),
    routes: [
        {
            path: '/login',
            component: LoginVue,
        },
        {
            path: '/register',
            component: RegisterVue,
        },
    ],
});
// 全局前置守卫
router.beforeEach((to, from, next) => {
    const isLogin = localStorage.getItem('token');
    if (!isLogin && to.path !== '/login') {
        next('/login');
    } else {
        next();
    }
});
export default router;

9. 请求时携带token

const axios = require('axios');

// 设置您的访问令牌
const token = 'your_access_token';

// 在请求中包含令牌
axios.get('https://api.example.com/data', {
  headers: {
    'Authorization': `Bearer ${token}`
  }
})
  .then(response => {
    // 处理返回的数据
    console.log(response.data);
  })
  .catch(error => {
    // 处理错误
    console.error('请求出错', error);
  });
