angular 2 interceptor

Hi,Please help me with this.

var requestnew = request.clone({
setHeaders: 
{
Authorization: Bearer ${this.auth.getToken()} //token is : eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9
}
});
return next.handle(requestnew)

Using Cloning not able to set headers … always getting response from server 401 unauthorized error …

node .js 
app.use(function(req,res,next){
console.log(req.header.Authorization) // getting undefined in console 
if(req.header(‘Authorization’) == ‘eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9’){

console.log(“next enetring”)
next();

}
else{
return res.status(401).json({message:‘Auth Fails’})
}
})
