我是 async/await 的新手，所以我有一個類似下面代碼的練習，我已經多次將此代碼轉換為 async/await ，但仍然沒有成功。請幫我。非常感謝！
我的代碼如下：
exports.register = (req, res) => {
const user = req.body;
try {
// Validate the registration form
validateRegisterForm(user)
.then((response) => {
// If response is true, hash the password
if (response) {
Md5Password(user.password)
.then(async (hash) => {
const { name, email } = user;
const newUser = new User({
name,
password: hash,
});
// Save the user
const savedUser = await newUser.save();
res.status(200).json(savedUser);
})
.catch((error) => {
res.status(500).json({
message: error.message,
err: "500: Internal Server Error",
});
});
}
// But if response is false, show the error message
else {
res.status(401).json({
message: errorMessage(),
error: "401: Unauthorized",
});
}
})
.catch((error) => {
res.status(500).json({
message: error.message,
err: "500: Internal Server Error",
});
});
} catch (error) {
res.status(500).json({
error: error.message,
message: "registration failed",
e: "500: Internal Server Error",
});
}
};
請幫幫我，非常感謝！
uj5u.com熱心網友回復：
不確定您要實作的確切目標，但這是您的代碼版本async/await：
exports.register = async (req, res) => {
const user = req.body;
try {
// Validate the registration form
const response = await validateRegisterForm(user);
// If response is true, hash the password
if (response) {
const hash = await Md5Password(user.password);
const { name, email } = user;
const newUser = new User({
name,
password: hash,
});
// Save the user
const savedUser = await newUser.save();
res.status(200).json(savedUser);
} else {
res.status(401).json({
message: errorMessage(),
error: "401: Unauthorized"
});
}
} catch (e) {
res.status(500).json({
message: e.message,
err: "500: Internal Server Error"
});
}
}
