[英]Bcrypt didn't assign the hashed password to body.password variable
module.exports.handle_sign_up = async (req,res) => { let body = req.body await bcrypt.hash(body.password, 10, (err,hash) => { body.password = hash console.log(hash) }) res.send(body) };
Above is my code which hashes body.password using bcrypt.以上是我使用 bcrypt 对 body.password 进行哈希处理的代码。 I tried to assign the hashed password to body.password in callback function but when res.send(body) executed it instead returns unhashed password meanwhile when I tried to console.log(hash) the hashed password it succesfully log the hashed password to the console.
我试图在回调函数中将散列密码分配给 body.password,但是当 res.send(body) 执行时,它返回未散列的密码,同时当我尝试 console.log(hash) 散列密码时,它成功地将散列密码记录到安慰。 Is there any problem that cause this?
是否有任何问题导致这种情况?
module.exports.handle_sign_up = async (req,res) => {
let body = req.body
let hashedPassword;
try{
hashedPassword = await bcrypt.hash(body.password,10);
body.password = hashedPassword;
console.log(hashedPassword,body.password);
}catch(err){
console.log(err)
})
res.send(body)
};
try and catch
try and catch
一种方法 module.exports.handle_sign_up = async (req,res) => {
let body = req.body
bcrypt.hash(body.password,10)
.then((hashedPassword) => {
body.password = hashedPassword;
})
.catch(err => console.log(err))
res.send(body)
};
await
returns a promise, if you dont store it , it is left as a promise which is not resolvedawait
返回一个承诺,如果你不存储它,它就会作为一个没有解决的承诺then and catch
then and catch
