如何使用vue中ajax请求和axios包

CDN: <script src="https://unpkg.com/axios/dist/axios.min.js"></script>
npm: npm install axios 并在全局的js中引入：import axios from 'axios';

axios.get('/user?ID=12345')
 .then(function (response) {
 console.log(response);
 })
 .catch(function (error) {
 console.log(error);
 });

 依赖于qs包，将对象转换成以&连接的字符串
//例：
axios.post( postUrl ,qs.stringify({userid:1,username:'yyy'})).then(function (response) {
 console.log(response);
})

axios.post('/user', context.state.test02)

.then(function(res){
 console.log(res)
})
.catch(function(err){
 console.log(err)
})

.then(function(res){
 console.log(this.data)
}.bind(this))
