vue3 ts setup中使用this.$axios

---

main.ts

在vue3中 proxy 可以充当 this 使用

import {App} from "vue"

import {getCurrentInstance} from "vue"
const {proxy} = getCurrentInstance()
const res=proxy.$axios.post("/globalApi/login",param)
console.log(res)

---

vue文件

import {getCurrentInstance} from "vue"
const {proxy} = getCurrentInstance()
const res = proxy.$axios.post("/globalApi/login",param)
console.log(res)
