获取解析的 json 值

Question

我正在尝试使用 bcrypt 检查保存在我的数据库中的哈希密码，但 json 响应当前返回如下：

[
    {
        "password": "$2a$10$8/o1McdQ24pL5MU7dkbhmewkjne83M2duPKp0cb6uowWvOPS"
    }
]

这会导致 bcrypt 比较出错，因为它正在比较整个响应，而不仅仅是其中的哈希值。我怎样才能在我的响应中获得哈希值？以下是我的代码：

app.get('/checkHash/:username/:pass', function(req, res) {
    console.log('below is the data');
    console.log(req.params);
    var pass = req.params.pass

        var createPromise = interact.getHash(req.params.username);
        //did promise
        createPromise.then(function(createResponse) {  
            //below checks to see if the password value matches the hash
            if(bcrypt.compareSync(pass, createResponse)) {
                //this means that the hashes are the same for user login
                res.json("yes");
            } else {
                //this means that the password hashes didn't match
                res.json("no");
         } 
        }).catch(function(err) {
        console.log(err);
    });
});

您的响应显然是一个对象数组。如果您只想比较数组的第一个结果，则必须将索引传递给数组。

app.get('/checkHash/:username/:pass', function(req, res) {
    console.log('below is the data');
    console.log(req.params);
    var pass = req.params.pass

        var createPromise = interact.getHash(req.params.username);
        //did promise
        createPromise.then(function(createResponse) {  
            //below checks to see if the password value matches the hash
            if(bcrypt.compareSync(pass, createResponse[0].password)) {
                //this means that the hashes are the same for user login
                res.json("yes");
            } else {
                //this means that the password hashes didn't match
                res.json("no");
         } 
        }).catch(function(err) {
        console.log(err);
    });
});
