Vue3+ts+setup getCurrentInstance使用时遇到的问题以及解决办法

// axios.ts
import axios from 'axios'
const app = Vue.createApp({})

// 全局自定义属性
declare module '@vue/runtime-core' {
  interface ComponentCustomProperties {
    $axios: AxiosInstance;
  }
}

app.config.globalProperties.$axios = axios

<script lang="ts" setup>
import { getCurrentInstance } from 'vue';

// 首先 此处 proxy ts会报
// 类型“ComponentInternalInstance | null”上不存在属性“proxy”。ts(2339)
const { proxy } = getCurrentInstance()

// 然后下面会报这个错误
// Unsafe member access .$axios on an `any` value.  eslint@typescript-eslint/no-unsafe-member-access
// Unsafe call of an `any` typed value.  eslint@typescript-eslint/no-unsafe-call
proxy.$axios('')

import { ComponentInternalInstance, getCurrentInstance } from 'vue';
// 添加断言
const { proxy } = getCurrentInstance() as ComponentInternalInstance

// 对象可能为 "null"。ts(2531)
proxy.$axios('')

proxy?.$axios('')

// @ts-ignoreconst { proxy } = getCurrentInstance();

import { ComponentInternalInstance, getCurrentInstance } from 'vue'export defaultfunction useCurrentInstance() {

    const { appContext } = getCurrentInstance() as ComponentInternalInstance

    const globalProperties = appContext.config.globalProperties

    return {

        globalProperties

    }

}

// 先引入文件
import useCurrentInstance from "@/hooks/useCurrentInstance";

...// 在setup 中使用处理
const { globalProperties } = useCurrentInstance();

const { ctx } = getCurrentInstance()

const { proxy } = getCurrentInstance()
