鸿蒙开发(31）http请求封装

一.utils文件夹下创建HttpUtils.ets

1. 导入模块

import {
    http } from '@kit.NetworkKit';

2. 导入常量，包含baseurl

import {
    BasicConstants } from '../Constants/BasicConstants'

3. 封装

/**
 * 封装请求的代码
 * **/
import {
   http} from '@kit.NetworkKit'
import {
    BasicConstants } from '../Constants/BasicConstants'
export function myRequest<T,K>(
  url:string,
  method:http.RequestMethod,
  requestData?:K
)
{
   
  //创建一个http对象
  const  httpRequest = http.createHttp()
  return new Promise((resolve:(value:Record<string,T>)=>void,reject:(value?:string)=>void)=>{
   
    //异步请求
    httpRequest.request(BasicConstants.BASE_URL+url,{
   
      method:method,
      // 开发者根据自身业务需要添加header字段
      header:{
