1.1 登录接口
//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);
}
//提供调用登录接口的函数
export const userLoginService = (loginData)=>{
const params = new URLSearchParams();
for(let key in loginData){
params.append(key,loginData[key])
}
return request.post('/user/login',params)
}
2.1 编写页面
2.2 绑定数据模型并校验
2.3 清空表单内的数据
2.4 调用登录接口
```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, userLoginService} 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')
}
//绑定数据,复用注册表单的数据模型
//表单数据校验
//登录函数
// import {useTokenStore} from '@/stores/token.js'
// import {useRouter} from 'vue-router'
// const router = useRouter()
// const tokenStore = useTokenStore();
const login =async ()=>{
//调用接口,完成登录
let result = await userLoginService(registerData.value);
if(result.code===0){
alert(result.msg? result.msg : '登录成功')
}else{
alert('登录失败')
}
// //alert(result.msg? result.msg : '登录成功')
// ElMessage.success(result.msg ? result.msg : '登录成功')
// //把得到的token存储到pinia中
// tokenStore.setToken(result.data)
// //跳转到首页 路由完成跳转
// router.push('/')
}
//定义函数,清空数据模型的数据
const clearRegisterData = ()=>{
registerData.value={
username:'',
password:'',
rePassword:''
}
}

3.1 修改响应拦截器以及提示框
//定制请求的实例
//导入axios npm install axios
import axios from 'axios';
import { ElMessage } from 'element-plus'
//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=>{
if(result.data.code===0){
return result.data;
}
ElMessage.error(result.data.msg?result.data.msg:'服务异常')
return Promise.reject(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;
