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
//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')
}
</script>

3.1 跨域问题
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''
}
}
}
})
