备注:我这里用的vue3

//请求一
const one = async() => {
   let params = {}
   const res = await $http(params)
   return res
}
//请求二
const two = async() => {
   let params = {}
   const res = await $http(params)
   return res
}
//promise.all()来使他们并行请求
const total = async() => {
   const res = await Promise.all([one(),two()])
   console.log('请求1',res[0])
   console.log('请求2',res[1])
}

成功！
