AggregateError: No Promise in Promise.any was resolved
當傳遞給 Promise.any() 的所有 Promise 都被拒絕時，會發生 JavaScript 異常 "Promise.any 中沒有 Promise 被解決"。它是 AggregateError 唯一的內建用法。
訊息
AggregateError: All promises were rejected (V8-based) AggregateError: No Promise in Promise.any was resolved (Firefox) AggregateError (Safari)
錯誤型別
AggregateError
哪裡出錯了？
Promise.any() 僅在傳遞給它的所有 Promise 都被拒絕時才會被拒絕。您應該訪問 errors 來獲取拒絕原因陣列。有關如何處理非同步拒絕的 Promise 的更多資訊，請參閱 使用 Promise。當 Promise.any() 收到空的可迭代物件時，也會引發此錯誤。
示例
空的可迭代物件
js
Promise.any([]).catch((error) => {
console.error(error); // AggregateError: No Promise in Promise.any was resolved
});
處理所有拒絕
js
const promises = [
fetch("/data-location1"),
fetch("/data-location1"),
fetch("/data-location1"),
];
Promise.any(promises)
.then((value) => console.log(value))
.catch((error) => {
// None of the fetches were successful
for (const e of error.errors) {
console.error(e);
}
});
// Using await
async function fetchFirstSuccessful() {
try {
const value = await Promise.any(promises);
console.log(value);
} catch (error) {
for (const e of error.errors) {
console.error(e);
}
}
}
