我有這三個可呼叫函式，它們都在運行它們的主要邏輯之前進行身份驗證檢查。這似乎不是很干，我想知道是否有更聰明的方法來重用這個身份驗證邏輯？
exports.addComment = functions.https.onCall(async (data, { auth }) => {
if (auth) {
//logic to add comment
} else {
throw new functions.https.HttpsError(
"failed-precondition",
"You must be authenticated"
);
}
});
exports.deleteComment = functions.https.onCall(async (data, { auth }) => {
if (auth) {
//logic to delete comment
} else {
throw new functions.https.HttpsError(
"failed-precondition",
"You must be authenticated"
);
}
});
exports.updateComment = functions.https.onCall(async (data, { auth }) => {
if (auth) {
//logic to update comment
} else {
throw new functions.https.HttpsError(
"failed-precondition",
"You must be authenticated"
);
}
});
uj5u.com熱心網友回復：
我會在這里為您的場景使用裝飾器。
基本上裝飾器是一個函式，它接收一個函式并通過包裝它來擴展它的功能。
所以它看起來像這樣：
function authDecorator(functionWithLogic) {
let innerFunc = () => {
if (auth) {
return functionWithLogic()
} else {
throw new functions.https.HttpsError(
"failed-precondition",
"You must be authenticated"
);
}
return innerFunc
}
您還可以擴展它并根據需要將相關引數傳遞給它
