mongoose的使用方法错误汇总篇

router.post('/login', function (req, res, next) {
  var param = {
    userName: req.body.userName,
    userPwd: req.body.userPwd
  }
  console.log('param', param)
  User.findOne({
    userName: req.body.userName,
    userPwd: req.body.userPwd//在这里Schame中写成了Number,
  }, function (err, doc) {
    if (err) {
      console.log('doc err')
      res.json({
        status: '1',
        msg: err.message
      })
    } else {
      console.log('doc else')
      console.log('doc', doc)
      if (doc) {
        console.log('doc true')
        res.cookie('userId', doc.userId, {
          path: '/',
          maxAge: 1000 * 60 * 60
        })
        res.json({
          status: '0',
          msg: '',
          result: {
            userName: doc.userName
          }
        })
      } else {
        res.json({
          status: '1',
          msg: '用户名不存在',

        })
      }
    }
  })

由于Schame中userPwd写成了Number,而通过req.body.userPwd得到的是String,所以一直验证不通过…
