Answer 1

我的问题是用这种方法解决的

db.collection('admin').findOne({"Email":req.body.Email},(err,result)=>{
try{ assert.equal(null,err);
assert.equal(req.body.Email,result.Email);

assert.equal(req.body.Password,result.Password);

console.log("found!!!!"+ result._id);
session.adminId=result._id;


res.redirect('/addstudent');
client.close();
}
catch(e){
session.studentId=null;
session.studentname = null;
session.registration=null;
session.Studentemail=null;
session.adminId=null;
console.log(e);
res.redirect('/admin');
}

})
