你可以在创建 axios 实例时添加一个 cancelToken 选项，并使用相同的 cancelToken 对象来取消多个请求。具体步骤如下：

1. 定义一个 cancelToken 对象

const CancelToken: CancelTokenStatic = axios.CancelToken
const source: CancelTokenSource = CancelToken.source()

2. 将 cancelToken 对象传递给所有请求的 config 中

config.cancelToken = source.token

3. 当需要取消请求时，调用 source.cancel()

source.cancel('取消请求')

完整代码如下：

import axios from 'axios'
import type {
  CancelTokenStatic,
  AxiosRequestConfig,
  AxiosInstance,
  AxiosError,
  InternalAxiosRequestConfig,
  AxiosResponse,
  CancelTokenSource,
} from 'axios'
import { useGlobalStore } from '@/stores'
import { hasOwn, hasOwnDefault } from '@/utils'
import { ElMessage } from 'element-plus'
