Vue3.x中使用Axios请求远程真实Api接口数据
https://github.com/axios/axios
1、安装
npm install axios --save
或者
yarn add axios
或者
cnpm install axios --save
2、引入使用
import Axios from "axios";
axios.get(‘/user?ID=12345‘)
.then(function (response) {
// handle success
console.log(response);
})
.catch(function (error) {
// handle error
console.log(error);
})
.then(function () {
// always executed
});
完整代码:
getData(){
var api=‘http://www.phonegap100.com/appapi.php?a=getPortalList&catid=20&page=1‘;
Axios.get(api).then((response)=>{
this.list=response.data.result;
}).catch((error)=>{
console.log(error);
})
}
二、Vue3.x全局绑定Axios
vue3.x中全局绑定属性参考:https://v3.vuejs.org/api/application-config.html#warnhandler
import { createApp } from ‘vue‘
import App from ‘./App.vue‘
import axios from ‘axios‘;
var app=createApp(App)
app.config.globalProperties.axios=axios
app.mount(‘#app‘)
三、Vue3.x中使用fetch-jsonp请求jsonp接口
axios不支持jsonp请求,如果我们要用jsonp来请求数据可以使用fetch-jsonp这个模块。
https://github.com/camsong/fetch-jsonp
import fetchJsonp from ‘fetch-jsonp‘;
getData() {
fetchJsonp(‘https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=php‘, {
jsonpCallback: ‘cb‘,
})
.then(function (response) {
return response.json()
}).then(function (json) {
console.log(json)
}).catch(function (ex) {
console.log(‘parsing failed‘, ex)
})
}
四、使用函数防抖实现百度搜索
<template>
<div class="home">
<button @click="getData()">获取数据</button>
<input type="text" v-model="keyword" @keyup="getData" />
<br>
<ul>
<li v-for="(item,index) in list" :key="index">{{item}}</li>
</ul>
</div>
</template>
<script>
import fetchJsonp from ‘fetch-jsonp‘;
export default {
data() {
return {
keyword: "",
list: [],
timer: ""
}
},
methods: {
getData() {
if (this.keyword != "") {
clearTimeout(this.timer);
this.timer = setTimeout(() => {
var api = "https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=" + this.keyword
fetchJsonp(api, {
jsonpCallback: ‘cb‘,
})
.then(function (response) {
return response.json()
}).then((json) => {
this.list = json.s
})
}, 200)
}
}
},
}
</script>
<style lang="scss">
.home {
padding: 20px;
}
</style>
