Mongoose findByIdAndUpdate 成功更新文档但出现错误 [英] Mongoose findByIdAndUpdate successfully updates document but ruturns error

问题描述

findByIdAndUpdate() 成功更新文档，但返回我不明白的错误.

findByIdAndUpdate() successfully updates document, but returns error which i don't understand.

这是架构:

const userSchema = mongoose.Schema({
    phone: String,
    password: String,
    token: String
});
const User = mongoose.model('User', userSchema);

这里是更新数据库中用户的函数

And here is function to update user in database

export const login = (req, res) => {
    User.findOne({ phone: req.body.phone }, (err, result) => {
        if (err) res.status(500).send(`User with ${req.body.phone} doesn't exist. \n Error: ${err}`);
        if( result.password === req.body.password ){
            // here Console.log(result) returns:
            //{ 
            //  _id: 5aa28eb4f4a8de28c24e6990,
            //  phone: '[phone]',
            //  password: 'passsss',
            //  token: '1520613346284',
            //  __v: 0 
            //}

            User.findByIdAndUpdate( result.id, { "token": Date.now() },
                (err, result) => {
                    // It gives error, of which stacktrace i give below. But if check database - 
                    // everything is fine, token was updated successfully
                    if (err) return res.status(500).send('Unable to create token. Error: ', err);
                    return res.status(200).send(result._id, result.token);
            })
        } else return res.status(500).send('Incorrect password');
    })
}

这是我在发布请求时在控制台中得到的内容，这些数据应该可以成功通过此检查并获取令牌.

Here is what i get in console when i do post request with data which should successfully pass this check and get token.

我不明白这个错误.为什么会出现?如果更新完成，为什么会出现错误?为什么我在任何地方都使用 res.status(status).send(body) 时会看到有关弃用的警告?也许是 Babel 给我带来了问题?有人知道我需要检查什么才能弄清楚发生了什么吗?

I don't understand this error. Why it appears? If update done, why there is an error at all? And why i see warning about deprecations if i use res.status(status).send(body), as it suggests, everywhere? Maybe it's Babel makes problems to me? Anybody know what i need to check to figure out whats going on?

推荐答案

body 参数可以是 Buffer 对象、String、对象或数组.

The body parameter can be a Buffer object, a String, an object, or an Array.

为了使其正常工作，请使用字符串插值:

For it to work properly, use string interpolation:

User.findByIdAndUpdate( result.id, { "token": Date.now() },
  (err, result) => {
    // It gives error, of which stacktrace i give below. But if check database - 
    // everything is fine, token was updated successfully
    if (err) return res.status(500).send(`Unable to create token. Error: ${err}`);
      return res.status(200).send(`${result._id}, ${result.token}`);
})
