module.exports = { 

     create:function(req,res){ 

       var param = req.body.name; 
       User.create({name :param.name}).exec(function(err,user){ 
         //console.log(success); 
        if(err){ 

         res.send("Error:Sorry!Something went Wrong"); 

        }else{

Answer 1

req.body.name Unter der Annahme, richtig formatierte Daten zurückgibt, dann würden Sie param statt param.name verwenden möchten, weil Sie die name Eigenschaft direkt an die Variable param Einstellung sind.

dies also tun:

var param = req.body.name; 
User.create({name : param}).exec(function(err,user){ 

Answer 2

Verwendung req.params.all(); oder verwenden Sie die Post-Methode im Postboten und Ihre URL wird http://localhost:1337/user/create?name=xyz sein.

Ich hoffe, dass es Ihr Problem

module.exports = lösen {

create:function(req,res){ 

      var param = req.params.all(); 
      User.create({name :param.name}).exec(function(err,user){ 
        //console.log(success); 
       if(err){ 

        res.send("Error:Sorry!Something went Wrong"); 

       }else{ 

        return res.redirect("/user"); 

       } 

      }); 
} 

};

Answer 3

Sie haben "name" mit Post-Anforderung zu übergeben, wie Post Mann post man request
