I need to replace Bearer from the header to verify the Token

Question

bearer = bearerHeader.replace("Bearer","");
jwt.verify(bearer, 'super_secret', function (err, decoded) {
    console.log(err);
    console.log(decoded);
});

Here is my code. Whenever I try to verify Token. I want to replace Bearer from header to verify only token. it will always goes to 'err' if a take Bearer. when i remove the Bearer from header i will work perfect. anyone please help me to solve this. Is there any way to solve this problem?

Output:

  { 
     [JsonWebTokenError: invalid token] name: 'JsonWebTokenError',
     message: 'invalid token'
  }

   undefined

Answer 1

if bearerHeader is something like "Bearer 456513" then your code

bearerHeader.replace("Bearer","");

will result: " 456513" (there are space before the token)

bearerHeader.replace('Bearer ',''); 

may solve your issue but I recommend to verify the authentification scheme first ("Bearer" term is really "Bearer"):

 var parts = bearerHeader.split(' ');
 if (parts.length === 2) {
   var scheme = parts[0];
   var credentials = parts[1];

   if (/^Bearer$/i.test(scheme)) {
     token = credentials;
     //verify token
     jwt.verify(token, 'super secret', function(err, decoded) {
     }
   }
}
