没有从JWT的有效载荷中获得所有的字段(not getting all the fields from payload of JWT)

 我创建了一个MEAN堆栈web应用程序，它具有登录注销选项。用户登录后，我使用了jsonwebtoken npm软件包。 这里的主要问题是当用户登录一个JWT时被创建，并且该令牌的有效负载包含用户名，电子邮件和全名，但是在解码令牌时我只获取用户名和电子邮件字段 
 
 这里是jwt.sign函数 - 
 
var token=jwt.sign({userid:user.username,email:user.email,fullname:user.fullname},secret,{expiresIn:'24h'});
 
 这里jwt.verify方法 - 
 
jwt.verify(token,secret,function(err,decoded){
    if(err){
        res.json({success:false,message:"invalid token"});
    } else {
        req.decoded=decoded;
        next();
    }
})
 
 令牌示例 -

 令牌解码 - 
 
{
    "userid": "nitin.sachdev",
    "email": "nitin.sachdev@email.com",
    "iat": 1484558012,
    "exp": 1484644412
}
 
 userSchema - 
 
 var UserSchema=new Schema({
    fullname:String,
    username:{type:String,lowercase:true,required:true,unique:true},
    password:{type:String,required:true},
    email:{type:String,required:true,lowercase:true,unique:true},
    contactno:Number,
    orgname:String
});

i have created a MEAN stack web app which has login logout option.for user to be logged in i have used jsonwebtoken npm package. the main problem here is when user logs in a JWT is created and in that token's payload contain username,email and fullname but while decoding the token i am only getting username and email field
 
here is jwt.sign function-
 
var token=jwt.sign({userid:user.username,email:user.email,fullname:user.fullname},secret,{expiresIn:'24h'});
 
and here jwt.verify method-
 
jwt.verify(token,secret,function(err,decoded){
    if(err){
        res.json({success:false,message:"invalid token"});
    } else {
        req.decoded=decoded;
        next();
    }
})
 
token example-
 
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyaWQiOiJuaXRpbi5zYWNoZGV2IiwiZW1haWwiOiJuaXRpbi5zYWNoZGV2QGVtYWlsLmNvbSIsImlhdCI6MTQ4NDU1ODAxMiwiZXhwIjoxNDg0NjQ0NDEyfQ.fWogT-aHJY4Xyc8Ebm4OXPkWD3poaWG3IAAf9VS-q58
 
token decoded-
 
{
    "userid": "nitin.sachdev",
    "email": "nitin.sachdev@email.com",
    "iat": 1484558012,
    "exp": 1484644412
}
 
userSchema -
 
 var UserSchema=new Schema({
    fullname:String,
    username:{type:String,lowercase:true,required:true,unique:true},
    password:{type:String,required:true},
    email:{type:String,required:true,lowercase:true,unique:true},
    contactno:Number,
    orgname:String
});
