貓鼬findByIdAndUpdate成功更新文檔，但失敗

Question

findByIdAndUpdate()成功更新文檔，但返回我不理解的錯誤。

這是模式：

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

這是更新數據庫中用戶的功能

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: '+79781231233434',
            //  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');
    })
}

這是我在發布帶有數據的請求時獲得的控制台信息，該數據應成功通過此檢查並獲得令牌。

我不明白這個錯誤。 為什么會出現？ 如果更新完成，為什么會出現錯誤？ 為什么我在各處都使用res.status(status).send(body)看到棄用警告？ 也許是Babel給我帶來了麻煩？ 有人知道我需要檢查以確定發生了什么嗎？

Answer 1

body參數可以是Buffer對象，String，對象或Array。

為了使其正常工作，請使用字符串插值：

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}`);
})
