Mongoose Casterror:cast to ObjectId failed for value

The restfull routes are as follows:

Router.get ('/:id ', controller.show);

The Mongoes code is as follows:

Exports.show = function(req, res) {
   Notice.findById(req.params.id, function (err, notice) {
     If(err) {
       Res.json({no:0,msg:‘Get failed: ‘+err});
     }else{
       Var result = {no:1};
       Result.obj=notice;
       Res.json(result);
     }
   });
};

Client Access:

Http://192.168.0.165:9000/api/notices/11

The printing results are as follows;

{
"no": 0,
"msg": "Get failed: CastError: Cast to ObjectId failed for value \"11\" at path \"_id\""
} 

Specific reasons for reference:

Mongoose's method casts the parameter to the type of the model's field so,findByIdid_idIt can properly query for The matching doc. This was an ObjectId"11"-a valid ObjectId so the cast fails.

If the client passes the MONGO Objectid, the above error is not reported. For example, the following access methods:

HTTP://192.168.0.165:9000/API/NOTICES/41224D776A326FB40F000001 will not error.

 
 
{
"no": 1,
"obj": null

}

Under normal circumstances, the ID parameter passed by the client is obtained from the background objectid, but for rigor now do the following:

Exports.show = function(req, res) {
   Var id = req.params.id;

   If (id.match(/^[0-9a-fA-F]{24}$/)) {
     Notice.findById(id, function (err, notice) {
       If(err) {
         Res.json({no:0,msg:‘Get failed: ‘+err});
       }else{
         Var result = {no:1};
         Result.obj=notice;
         Res.json(result);
       }
     });
   }else{
     Res.json({no:0,msg:id+‘no ‘});
   }

};
