現在需求是需要先執行getA獲取私鑰，然后執行requestLoading請求介面。但是requestLoading是直接暴露出去的會被直接呼叫。該怎么辦

function requestLoading (){//requestLoading 邏輯
}
function getA(callback){
//getA邏輯
callback();
}
getA(function(){
requestLoading();
});

uj5u.com熱心網友回復：
這方法試了，不行的。1樓兄弟的還是異步，2樓兄弟的寫法有問題的會報錯的uj5u.com熱心網友回復：
function asyncFn(){
return new Promise((resolve,reject) => {
//在需要的地方呼叫resolve()表示當前函式執行結束,可傳參
resolve(1)
})
}
function fn(){
asyncFn().then(res => console.log(res))
}
fn()
uj5u.com熱心網友回復：
4樓的兄弟提供的這個也不行啊uj5u.com熱心網友回復：
方法1：回呼函式大法方法2：async/await大法
