毕业设计做app还是做网站大型网站系统解决方案

---

一、开发步骤

二、效果图

三、搭建页面

创建views/Login.vue

完整内容在后面

在App.vue中导入Login.vue

<script setup>import LoginVue from '@/views/Login.vue'</script><template><LoginVue/>
</template><style scoped></style>

四、数据绑定

vue注册用户使用v-model实现数据双向绑定

五、表单校验

vue使用rules实现表单校验——校验用户名和密码

六、访问后端 API 接口，完成注册

vue访问后端接口，实现用户注册

七、完整的Login.vue代码

<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: '',confirmPassword: ''
})//校验密码的函数
const validateConfirmPassword = (rule, value, callback) => {if (value === '') {callback(new Error('请再次输入密码'))} else if (value !== registerData.value.password) {callback(new Error('两次密码不一致'))} 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: '长度在 5 到 16 个字符', trigger: 'blur' }],password: [{ required: true, message: '请输入密码', trigger: 'blur' },{ min: 5, max: 16, message: '长度在 5 到 16 个字符', trigger: 'blur'}],confirmPassword: [{validator: validateConfirmPassword, trigger: 'blur'}]
}//调用后台接口完成注册
import { userRegisterService } from '@/api/user.js'
const register = async () => {let result = await userRegisterService(registerData.value)if (result.code === 0) {//注册成功alert(result.msg ? result.msg : '注册成功')} else {//注册失败alert('注册失败')}alert(result.msg ? result.msg : '注册成功')
}
