My code looks like this,
我的代码看起来像这样，
export function handleLogin(window,userData){
return (dispatch) => {
Meteor.call('checkUserLogin',userData,
(error,result)=>{
if(result.isLogin && !error) {
Meteor.call('SOMECALL',SOMEDATA (e,r)=>{
if(!e) {
async function getData(){ return await getAdminUgData();}
getData()
.then((d)=>{console.log('resolve!!');})
.catch((e)=>{console.log('!!reject'); });
}
});
});
}; }
the getAdminUgData is,
getAdminUgData是，
export function getAdminUgData(){
return new Promise((resolve, reject) => {
Meteor.call('adminGetUserGroupData', (e,r)=>{
if(e) reject(new Error('error'));
else resolve(r);
});
});}
I am supposed to print out 'resolve' only because the resolve(r); is confirmed being called in getAdminUgData. But the confusing/weird reality is that 'resolve!!' is printed and after that, '!!reject' is also printed. And I completely have no ideas about this. Any suggestions are welcome; thanks.
我应该打印'决心'只因为决心（r）;确认在getAdminUgData中被调用。但令人困惑/奇怪的现实是“解决!!”打印后，打印出'!! reject'。我对此完全没有任何想法。欢迎任何建议;谢谢。

No, it's absolutely impossible for the same promise to both reject and fulfill - and so it will never happen that both callbacks to .then(…, …) are called. It is however totally possible that both a .then(…) and a .catch(…) callback are called when chained - notice that this doesn't seem to be the case in your example, it seems there's something else going on.
不，绝对不可能同时承诺拒绝和履行 - 所以永远不会发生对.then（......，...）的回调都被调用。然而，链接时调用.then（...）和.catch（...）回调完全有可能 - 请注意，在您的示例中似乎不是这种情况，似乎还有其他事情发生。
