Axios网络请求_GET
Axios 是一个基于 promise 的 HTTP 库,可以用在浏览器和 node.js 中
安装Axios
npm install --save axios
GET请求
<template>
<h3>网络请求</h3>
<ul>
<li v-for="item in bannerObj.banner" :key="item">
<h3>{{ item.title }}</h3>
<p>{{ item.content }}</p>
</li>
</ul>
</template>
<script setup>
import { onMounted,reactive } from "vue"
import axios from "axios"
const bannerObj = reactive({
banner:{}
})
onMounted(() =>{
axios.get("http://iwenwiki.com/api/blueberrypai/getIndexBanner.php")
.then(res =>{
bannerObj.banner = res.data.banner
})
.catch(error =>{
console.log(error)
})
})
</script>
带参数GET请求
<template>
<h3>网络请求</h3>
<div>
<h3>{{ music.songInfo.song_title }}</h3>
<p>{{ music.songInfo.song_intro_cont }}</p>
</div>
</template>
<script setup>
import { onMounted,reactive } from "vue"
import axios from "axios"
const music = reactive({
songInfo:{}
})
onMounted(() =>{
axios.get("http://iwenwiki.com/api/blueberrypai/getSongInfo.php?song=mo")
.then(res =>{
music.songInfo = res.data.songInfo
})
.catch(error =>{
console.log(error);
})
})
</script>
axios.get("http://iwenwiki.com/api/blueberrypai/getSongInfo.php",{
params:{
song:"mo"
}
})

1.下列代码,画横线处应该填写的代码是:
<script setup> import { onMounted,reactive } from "vue" import axios from "axios" const music = reactive({ songInfo:{} }) onMounted(() =>{ ___.get("http://iwenwiki.com/api/blueberrypai/getSongInfo.php?song=mo") .then(res =>{ music.songInfo = res.data.songInfo }) .catch(error =>{ console.log(error); }) }) </script>
A axios
B fetch
C ajax
D XHR
Axios网络请求_POST
安装依赖
axios POST接收的网络请求参数需要进行格式转化
需求的格式 username=iwen
npm install --save querystring
<template>
<h3>网络请求_POST</h3>
</template>
<script setup>
import { onMounted } from "vue"
import axios from "axios"
import qs from "querystring"
onMounted(() =>{
axios.post("http://iwenwiki.com/api/blueberrypai/login.php",qs.stringify({
user_id:"iwen@qq.com",
password:"iwen123",
verification_code:"crfvw"
}))
.then(res =>{
console.log(res.data);
})
.catch(error =>{
console.log(error);
})
})
</script>
Axios网络请求_并发请求
在真实场景中,有可能会需要一次性获取多个网络请求的结果
处理并发请求的助手函数
<template>
<h3>网络请求_合并并发请求</h3>
</template>
<script setup>
import { onMounted } from "vue"
import axios from "axios"
function getBanner(){
return axios.get("http://iwenwiki.com/api/blueberrypai/getIndexBanner.php")
}
function getChating(){
return axios.get("http://iwenwiki.com/api/blueberrypai/getIndexChating.php")
}
onMounted(() =>{
axios.all([getBanner(), getChating()])
.then(axios.spread((banner,chating) =>{
console.log(banner.data,chating.data);
}))
})
</script>

A axios
B fetch
C all
D spread
Axios网络请求_全局配置
全局引入 axios 应用会更加方便
全局引用方案一
vue的全局处理方案 app.config.globalProperties 可以实现
import { createApp } from 'vue'
import App from './App.vue'
import axios from "axios"
const app = createApp(App)
app.config.globalProperties.$axios = axios
app.mount('#app')
<template>
<h3>网络请求</h3>
<ul>
<li v-for="item in fingerUnion.data" :key="item">
<h3>{{ item.title }}</h3>
<p>{{ item.content }}</p>
</li>
</ul>
</template>
<script setup>
import {
onMounted,reactive,getCurrentInstance } from "vue"
const { proxy } = getCurrentInstance();
const fingerUnion = reactive({
data:{}
})
onMounted(() =>{
proxy.$axios.get("http://iwenwiki.com/api/blueberrypai/getIndexBanner.php")
.then(res =>{
fingerUnion.data = res.data.banner
})
})
</script>
全局引用方案二
利用依赖注入,利用 Provide 和 Inject
import { createApp } from 'vue'
import App from './App.vue'
import axios from "axios"
const app = createApp(App)
app.provide("axios",axios)
app.mount('#app')
<template>
<h3>网络请求</h3>
<ul>
<li v-for="item in fingerUnion.data" :key="item">
<h3>{{ item.title }}</h3>
<p>{{ item.content }}</p>
</li>
</ul>
</template>
<script setup>
import { onMounted,reactive,inject } from "vue"
const axios = inject("axios")
const fingerUnion = reactive({
data:{}
})
onMounted(() =>{
axios.get("http://iwenwiki.com/api/blueberrypai/getIndexBanner.php")
.then(res =>{
fingerUnion.data = res.data.banner
})
})
</script>
