Vue3 使用axios时，Vue3没有this怎么办

npm install axios

npm install --save axios vue-axios

配置：

import Vue from 'vue'
import axios from 'axios'
import VueAxios from 'vue-axios'
 
Vue.use(VueAxios, axios)

用法：

Vue.axios.get(api).then((response) => {
  console.log(response.data)
})
 
this.axios.get(api).then((response) => {
  console.log(response.data)
})
 
this.$http.get(api).then((response) => {
  console.log(response.data)
})
