HarmonyOS 鸿蒙Next axios封装

在此基础上还可以定义get、post等进一步简化逻辑：

//封装网络请求
import axios, { AxiosError, AxiosRequestConfig, AxiosResponse, InternalAxiosRequestConfig } from '@ohos/axios'
import { IStandardBackInfo, IUserToken } from './interfaces'
import { promptAction } from '@kit.ArkUI'

//定义基地址
const instance = axios.create({ baseURL: 'https://www.abcdefg.com' })

//添加请求拦截器
instance.interceptors.request.use((config: InternalAxiosRequestConfig) => {
  const userTokens = AppStorage.get("userToken") as IUserToken
  const userToken = userTokens.token
  const userTokenRefresh = userTokens.refresh_token
  const ifRefresh = AppStorage.get("ifRefresh") as boolean
  if (userToken !== '') {
    if (ifRefresh) {
      config.headers.Authorization = `Bearer ${userTokenRefresh}`
    } else {
      config.headers.Authorization = `Beare ${userToken}`
    }
  }
  return config
}, (error: AxiosError) => {
  return Promise.reject(error)
})

//添加响应拦截器
instance.interceptors.response.use((response: AxiosResponse) => {
  return response
}, async (error: AxiosError) => {
  if (error.response?.status === 400) {
    AppStorage.setOrCreate("ifRefresh", true)
    promptAction.showToast({
      message: JSON.stringify(error.response.data),
      duration: 1000
    })
  } else if (error.response?.status === 401) {
    const resData = await sendRequest<IStandardBackInfo<string>, null>({
      url: '/v1_0/authorizations',
      method: 'put'
    })
    AppStorage.set("userToken", resData.data.data["token"])
    AppStorage.setOrCreate("ifRefresh", false)
  }
  return Promise.reject(error)
})

//T响应类型，D提交类型
export function sendRequest<T = null, D = null>(config?: AxiosRequestConfig<D>) {
  return instance<null, AxiosResponse<T, null>, D>(config)
}
