【问题描述】:
我正在处理 NodeJS 中的密码更改,在我的请求处理过程中出现以下错误:
(node:16220) UnhandledPromiseRejectionWarning: Error: Can't set headers after they are sent.

在我的changePassword 路线中,我采用email,password,newPassword 值和:
检查电子邮件是否存在,如果存在...
比较给定密码和用户密码,如果它们相同...
bcrypt.hash函数获取 newPassword,从中生成哈希,并保存到 mongoDB
如果我提供正确的电子邮件和密码,以上所有点都已完成,但我知道UnhandledPromiseRejectionWarning。
我看到这个问题的原因在 user[0].updateOne(user[0]) 函数内部,正好在 catch() 但我不知道发生了什么。
// CHANGE USER PASSWORD
exports.changePassword = (req, res, next) => {
User.find({ email: req.body.email })
.then(user => {
if (user.length < 1) {
return res.status(401).json({
message: 'Auth failed'
})
}
const { password, newPassword } = req.body
console.log(password, newPassword)
bcrypt.compare(req.body.password, user[0].password, (err, result) => {
console.log(result)
if (err) {
return res.status(401).json({
message: 'Error! Something goes wrong'
})
}
if (result) {
bcrypt.hash(newPassword, 10, (err, hash) => {
console.log(hash)
if (err) {
return res.status(500).json({
error: err
})
} else {
user[0].password = hash
user[0]
.updateOne(user[0])
.then(result => {
return res.status(200).json({
message: 'Password changed!',
result: result,
})
})
.catch(err => {
res.status(500).json({ message: err.message })
})
}
})
}
return res.status(401).json({
message: 'Auth failed'
})
})
})
.catch(err => {
res.status(500).json({ error: err })
})
}
我需要从我的请求中得到[200]'Password changed!' 的答复,但由于UnhandledPromiseRejectionWarning,我得到了[401]'Auth failed'。
【问题讨论】:
-
你有任何中间件会响应 401 吗?
