https://blog.csdn.net/m0_67930426/article/details/134816155?spm=1001.2014.3001.5502
2. 整合element-ui
https://blog.csdn.net/m0_67930426/article/details/134827986?spm=1001.2014.3001.5502
在view目录下创建文件
本篇内容使用到了 v-model @click 指令
具体用法可以参考

知识集锦
el-form的model属性
el-from-item 的 prop 属性
el-from-item 的 prop 属性必须与 el-input 中需要校验的表单属性一致
el-form的rules属性
校验规则
此处对应的是
el-form的ref属性
表单验证
此处对应
prefix-icon
图标显示
element-ui
https://element.eleme.cn/#/zh-CN/component/icon
show-password
输入密码的时候会隐藏起来
对比一下不使用show-password
通过对比效果一目了然
表单校验
Login.vue中的
methods: {
login () {
this.$refs.userForm.validate((valid) => {
if (valid) { // 表单校验合法
this.request.post('/user/login', this.user).then(res => {
if (res.code === '200') {
localStorage.setItem('user', JSON.stringify(res.data)) // 存储用户信息到浏览器
localStorage.setItem('menus', JSON.stringify(res.data.menus)) // 存储用户信息到浏览器
// 动态设置当前用户的路由
setRoutes()
this.$message.success('登录成功')
if (res.data.role === 'ROLE_STUDENT') {
this.$router.push('/front/home')
} else {
this.$router.push('/')
}
} else {
this.$message.error(res.msg)
}
})
}
})
}
}1.
if (valid)如果表单校验合法，就执行下一步
这里的表单校验合法是指
这一部分校验通过
2.
this.request.post('/user/login', this.user).then(res => 这里的 ' /user/login ' 对应后端控制层里的登录接口
this.user 即在input 输入的账号和密码
总的来说，使用request.post方法向后端发送请求，并提交表单数据
3.
if (res.code === '200') {
http请求成功的响应值
请求成功，执行后面的操作
例如，将用户信息存储到浏览器
