mongodb - 登录用户时遇到问题

Question

我收到错误 TypeError: Cannot read property 'email' of undefined 尝试登录用户并且不允许我登录。我的代码有问题吗？我的 mongo 管理员/教师模型和控制器示例（我正在使用 jwt 身份验证）

const mongoose = require('mongoose');
const { isEmail, isLength } = require('validator');
const bcrypt = require('bcryptjs');

const { Schema, model } = mongoose;

const TeacherSchema = new Schema({
  email: {
    type: String,
    unique: true,
    validate: [isEmail, 'Please enter a valid email address'],
    required: [true, 'You must provide an email address'],
  },
  password: {
    type: String,
    required: [true, 'You must provide a password'],
    validate: [(value) => isLength(value, { min: 6 }), 'Your password must be at least 6 characters long'],
  },
  dateCreated: {
    type: Date,
    default: Date.now(),
  },
  myImages:[{
    type:[Schema.Types.ObjectId],
    ref:'Image'
  }],
  myGrade:[{
    type:[Schema.Types.ObjectId],
    ref:'Grade'
  }],
  myCourses: [{
    type: [Schema.Types.ObjectId],
    ref: 'Course',
  }],
  myStocks: [{
    type: [Schema.Types.ObjectId],
    ref: 'Stock',
  }],
});

TeacherSchema.methods.toJSON = function() {
  var obj = this.toObject();
  delete obj.password;
  return obj;
};


TeacherSchema.methods.comparePassword = async function (candidatePassword) {
  const teacher = this;
  try {
    const isMatch = await bcrypt.compare(candidatePassword, teacher.password);
    return Promise.resolve(isMatch);
  } catch (e) {
    return Promise.reject(e);
  }
};

TeacherSchema.pre('save', async function (next) {
  // gets access to the user model that is currently being saved
  const teacher = this;
  if (teacher.isModified('password')) {
    try {
      const salt = await bcrypt.genSalt();
      const hash = await bcrypt.hash(teacher.password, salt);
      // overwrite the plain text password with our hash
      teacher.password = hash;
      // Finally call save
      next();
    } catch (e) {
      // Call save with an error
      next(e);
    }
  }
  next();
});

module.exports = model('Teacher', TeacherSchema);

这是控制器和路由的示例

const { isEmail, isLength } = require('validator');
const jwt = require('jwt-simple');
const axios = require('axios');
const { Teacher } = require('../models');
const { secret, GITHUB_CLIENT_SECRET } = require('../config');

function tokenForUser(teacher) {
  const timeStamp = new Date().getTime();
  return jwt.encode({ sub: teacher._id, iat: timeStamp }, process.env.SECRET || secret);
}

 

module.exports = {
  teacherSignUp: async (req, res) => {

    const {
       
      email,
      password
      
    } = req.body;
     if (!email || !password) {
      return res
        .status(422)
        .json({ error: 'You must provide email and password' });
    }
    if (!isEmail(email)) {
      return res
        .status(403)
        .json({ error: 'You must provide a valid email address' });
    }
    if (!isLength(password, { min: 6 })) {
      return res
        .status(403)
        .json({ error: 'Your password must be at least 6 characters long' });
    }
    try {
      // See if a user with the given email exists
      const existingTeacher = await Teacher.findOne({ email });
      if (existingTeacher) {
        return res
          .status(403)
          .json({ error: 'User already exists' });
      }
      const teacher = await new Teacher({
        
        email,
        password,
        
      }).save();

       const currentTeacher = await Teacher.findById(teacher._id).select('-password');
      // Eventually we will send a token
      
      return res.json({ token: tokenForUser(teacher), teacher: currentTeacher });
    } catch (e) {
      return res
        .status(403)
        .json({ e });
    }
  },
  teacherSignin: async (req, res) => {
     const currentUser = await Teacher.findOne({ email: req.teacher.email }).select('-password');
    console.log(currentUser,'current teacher email signin auth')
    res.json({ token: tokenForUser(req.teacher), teacher: currentUser });
  },
};

my route 

const router = require('express').Router(); const {teacherSignUp，teacherSignin } = require('../../../controllers/teacherAuth');

const { trequireSignIn } = require('../../../tmiddlewares/tauthMiddlewares');

// /api/tauth/teachersignup // /api/tauth/teachersignin

router.post('/teachersignup', teacherSignUp); router.post('/teachersignin', trequireSignIn, teacherSignin);

module.exports = 路由器；

我在前端的 axios 请求。（我使用 redux 形式）

      dispatch({ type: AUTH_TEACHER, payload: data.token });
      this.props.history.push('/watchlist');
     } catch (e) {
