1.1 request.js请求工具

//定制请求的实例

//导入axios  npm install axios
import axios from 'axios';
//定义一个变量,记录公共的前缀  ,  baseURL
const baseURL = '/api';
const instance = axios.create({baseURL})


//添加响应拦截器
instance.interceptors.response.use(
    result=>{
        return result.data;
    },
    err=>{
        alert('服务异常');
        return Promise.reject(err);//异步的状态转化成失败的状态
    }
)

export default instance;

2.1 编写注册接口

Spring Boot 笔记 023 注册页面,Spring Boot,spring boot,笔记,vue.js

//导入request.js请求工具
import request from '@/utils/request.js'

//提供调用注册接口的函数
export const userRegisterService = (registerData)=>{
    //借助于UrlSearchParams完成传递
    const params = new URLSearchParams()
    for(let key in registerData){
        params.append(key,registerData[key]);
    }
    return request.post('/user/register',params);
}

3.1 编写页面

3.2 给表单绑定数据

3.3 定义表单校验规则

3.4 调用注册接口

```html
<script setup>
import { User, Lock } from '@element-plus/icons-vue'
import { ref } from 'vue'
//控制注册与登录表单的显示， 默认显示注册
const isRegister = ref(false)

//定义数据模型
const registerData = ref({
    username: '',
    password: '',
    rePassword: ''
})

//校验密码的函数
const checkRePassword = (rule, value, callback) => {
    if (value === '') {
        callback(new Error('请再次确认密码'))
    } else if (value !== registerData.value.password) {
        callback(new Error('请确保两次输入的密码一样'))
    } else {
        callback()
    }
}

//定义表单校验规则
const rules = {
    username: [
        { required: true, message: '请输入用户名', trigger: 'blur' },
        { min: 5, max: 16, message: '长度为5~16位非空字符', trigger: 'blur' }
    ],
    password: [
        { required: true, message: '请输入密码', trigger: 'blur' },
        { min: 5, max: 16, message: '长度为5~16位非空字符', trigger: 'blur' }
    ],
    rePassword: [
        { validator: checkRePassword, trigger: 'blur' }
    ]
}

//调用后台接口,完成注册
import { userRegisterService} from '@/api/user.js'
const register = async () => {
    //registerData是一个响应式对象,如果要获取值,需要.value
    let result = await userRegisterService(registerData.value);
    if (result.code === 0) {
        //成功了
        alert(result.msg ? result.msg : '注册成功');
    }else{
        //失败了
        alert('注册失败')
    } 
    //alert(result.msg ? result.msg : '注册成功');
    // ElMessage.success(result.msg ? result.msg : '注册成功')
}

3.1 跨域问题

Spring Boot 笔记 023 注册页面,Spring Boot,spring boot,笔记,vue.js

3.1.1 修改request.js

//定制请求的实例

//导入axios  npm install axios
import axios from 'axios';
//定义一个变量,记录公共的前缀  ,  baseURL
const baseURL = '/api';
const instance = axios.create({baseURL})


//添加响应拦截器
instance.interceptors.response.use(
    result=>{
        return result.data;
    },
    err=>{
        alert('服务异常');
        return Promise.reject(err);//异步的状态转化成失败的状态
    }
)

export default instance;

3.1.2 修改vite.config.js

import { fileURLToPath, URL } from 'node:url'

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

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    vue(),
  ],
  resolve: {
    alias: {
      '@': fileURLToPath(new URL('./src', import.meta.url))
    }
  },
  server:{
    proxy:{
      '/api':{//获取路径中包含了/api的请求
          target:'http://localhost:8080',//后台服务所在的源
          changeOrigin:true,//修改源
          rewrite:(path)=>path.replace(/^\/api/,'')///api替换为''
      }
    }
  }
})
