二. Promise.allSettled

const p1 = new Promise((resolve, reject)=>{
      setTimeout(()=>{
            resolve(‘商品数据-1‘)
      },1000)
})

const p2 = new Promise((resolve, reject)=>{
      setTime(()=>{
            //resolve(‘商品数据-2‘)
            reject(‘出错啦‘)
      })
})      

//调用 allsettled 方法
const result = Promise.allSettled([p1,p2]);      //状态都返回

const res = Promise.all([p1,p2]);                 // 只返回成功的状态

console.log(res)
