函数回调不执行

Question

我有以下注册路线，在成功注册后应该发送验证消息，目前没有运行.

示例：mailer.sendEmail(res, req.body, token)。

控制台中没有错误。我传递参数的方式可能有问题。

有人能帮忙吗？

server.js

app.post('/signup-user', upload.single('avatar'), (req, res) => {
    let sSignupUserImagePath = req.file.path.split("public/").pop()
    Object.defineProperty(global, "sSignupUserImagePath", {
        value: sSignupUserImagePath
    })
    let token = jwt.sign({
        username: req.body.email,
    }, 'supersecret', {
        expiresIn: 240
    });
    user.signupUser(req.body, (err) => {
        if (!err) {
            mailer.sendEmail(res, req.body, token)
        }
    })
})

user.js

var user = {}

user.signupUser = (jUserData, res) => {

    var aData = [
        null,
        jUserData.first_name,
        jUserData.last_name,
        jUserData.email,
        jUserData.mobile_number,
        sSignupUserImagePath,
        0
    ]
    var sQuery = 'INSERT INTO users VALUES (?, ?, ?, ?, ?, ?, ?)'

    db.run(sQuery, aData, (err) => {
        if (err) {
            console.log('BAD, user not registered')
            return res(err)
        }
        console.log('GREAT, user registered')
    });
}

Answer 1

在执行它们时，您没有调用传递给函数的 res 函数；如果一切顺利，您必须致电：

db.run(sQuery, aData, (err) => {
    if (err) {
        console.log('BAD, user not registered')
        return res(err)
    }
    console.log('GREAT, user registered');
    res(null); //or also res(); works
});
