一、使用 vite+webstorm 搭建 Vue 环境，构建前端
1、结构树
2、main.js
import { createApp } from 'vue'
//import './style.css'
import App from './App.vue'
import router from "./utils/router";
createApp(App).use(router).mount('#app')
3、http.js
import axios from "axios"; // 要导入安装的包，则直接填写包名即可。不需要使用路径
// 实例化
const http = axios.create({
//baseURL: 'http://wthrcdn.etouch.cn/', // 请求的公共路径,一般填写服务端的默认的api地址，这个地址在具体使用的时候覆盖
baseURL: 'http://127.0.0.1:8000/vue/', // 请求的公共路径,一般填写服务端的默认的api地址，这个地址在具体使用的时候覆盖
timeout: 8000, // 最大请求超时时间，请求超过这个时间则报错，有文件上传的站点不要设置这个参数
//headers: {'X-Custom-Header': 'foobar'} // 默认的预定义请求头，一般工作中这里填写隐藏了客户端身份的字段
});
export default http;
4、router.js
import {createRouter, createWebHistory} from 'vue-router';
import Login from "../views/Login.vue";
import Register from "../views/Register.vue";
import Index from "../components/Index.vue";
const router = createRouter({
history: createWebHistory(),
routes: [
{
path: "/",
name: "myLogin",
component: Login,
},
{
path: "/login",
name: "Login",
component: Login,
},
{
path: "/reg",
name: "Register",
component: Register,
},
{
path: "/index",
name: "Index",
component: Index,
},
]
})
export default router;
5、App.vue
<script>
</script>
<template>
<router-view></router-view>
</template>
<style scoped>
</style>
6、Index.vue
<template>
<button><router-link to="/reg">register</router-link></button>
<button><router-link to="/login">login</router-link></button>
<h3 @click="log">{{ message }}</h3>
<span>{{ login_message }}</span>
</template>
<!-- 以下为选项API格式 -->
<script>
export default {
name: "Index",
data() {
return {
message: "welcome to INDEX",
login_message: '登录成功！！！',
}
},
methods: {
log() {
console.log(this.message)
},
},
}
</script>
<style scoped>
</style>
7、Register.vue
<template>
<hr>
<h1>注册页面</h1>
<hr>
用户账号：<input type="text" v-model="username"><span>{{ info1 }}</span><br>
设置密码：<input :type="password1" v-model="passwd1">
<button @click="pwd1">{{ tip1 }}</button>
<span>{{ info2 }}</span><br>
确认密码：<input :type="password2" v-model="passwd2">
<button @click="pwd2">{{ tip2 }}</button>
<span>{{ info2 }}</span><br>
<button><a href="/login" @click.prevent="send_post">register</a></button>
<button>
<router-link to="/login">login</router-link>
</button>
</template>
<script>
import http from "../utils/http.js";
export default {
name: "Register",
data() {
return {
username: '请输入用户名',
passwd1: '请输入密码',
passwd2: '请确认密码',
password1: 'password',
password2: 'password',
tip1: '显示密码',
tip2: '显示密码',
num1: 0,
num2: 0,
info1: '',
info2: ''
}
},
methods: {
pwd1() {
if (this.num1 === 0) {
this.password1 = 'text'
this.tip1 = '隐藏密码'
this.num1 = 1
} else {
this.password1 = 'password'
this.tip1 = '显示密码'
this.num1 = 0
}
},
pwd2() {
if (this.num2 === 0) {
this.password2 = 'text'
this.tip2 = '隐藏密码'
this.num2 = 1
} else {
this.password2 = 'password'
this.tip2 = '显示密码'
this.num2 = 0
}
},
send_post() {
http.post("http://127.0.0.1:8000/vue/", {
username: this.username,
passwd: this.passwd1,
passwd2: this.passwd2,
},
).then(response => {
//console.log(response.data); // 服务端响应的响应体
if (response.data.state == 'fail1') {
//console.log('注册失败')
this.info1 = response.data.tip
this.info2 = ''
} else if (response.data.state == 'fail2') {
this.info1 = ''
this.info2 = response.data.tip
} else {
window.location.href = "/login"
}
}).catch(error => {
console.log('请求错误！error=', error)
})
},
}
}
</script>
<style scoped>
* {
margin: 10px;
}
span {
color: red;
}
</style>
8、Login.vue
<template>
<hr>
<h1>登录页面</h1>
<hr>
账号：<input type="text" v-model="username"><span>{{ info3 }}</span><br>
密码：<input :type="password" v-model="passwd">
<button @click="pwd">{{ tip }}</button>
<span>{{ info4 }}</span>
<br>
<button>
<a href="/" @click.prevent="send_post">login</a>
</button>
<button>
<router-link to="/reg">register</router-link>
</button>
</template>
<script>
import http from "../utils/http.js";
export default {
name: "Login",
data() {
return {
username: '请输入用户名',
passwd: '请输入密码',
password: 'password',
tip: '显示密码',
num: 0,
info3: '',
info4: '',
}
},
methods: {
pwd() {
if (this.num === 0) {
this.password = 'text'
this.tip = '隐藏密码'
this.num = 1
} else {
this.password = 'password'
this.tip = '显示密码'
this.num = 0
}
},
send_post() {
http.post("http://127.0.0.1:8000/vue/", {
username: this.username,
passwd: this.passwd,
},
).then(response => {
//console.log(response.data); // 服务端响应的响应体
if (response.data.state == 'fail3') {
//console.log('注册失败')
this.info3 = ''
this.info4 = response.data.tip
} else if (response.data.state == 'fail4') {
this.info3 = response.data.tip
this.info4 = ''
} else {
window.location.href = "/index"
}
}).catch(error => {
console.log('请求错误！error=', error)
})
},
}
}
</script>
<style scoped>
* {
margin: 10px;
}
span {
color: red;
}
</style>
