如何把promise改写成async函数

Question

有下面一段代码，想把它改成async函数封装起来，让那个res能在函数间传递，怎么改？

const p = new Promise((resolve,reject)=>{
    consumer.get("http://localhost:8081/rest/api/2/search?maxResult=30",
       "AU23PexY8GwT11FQmkifgADtkUf9Wyio",
       "FvKnQBhQ7ARfDodEXYw8ejHF5MsM7v9p",
       function(error,res){
        resolve(res);
    })
    
})
p.then(res=>{
    console.log(res);
})

你这样调用就可以了啊

const p = () => {
    return new Promise((resolve,reject)=>{
    consumer.get("http://localhost:8081/rest/api/2/search?maxResult=30",
       "AU23PexY8GwT11FQmkifgADtkUf9Wyio",
       "FvKnQBhQ7ARfDodEXYw8ejHF5MsM7v9p",
       function(error,res){
        resolve(res);
    }) 
})
}
const res = await p()
// 或者
async () => {
    const res = await p();
    // ....
}
