How I can pass value from function to another one at router.get

router.get('/someurl', (req, res, next) => {
const token = req.headers.authorization.split(' ')[1] //jwtToken
const jwt = jwt.verify(
    token,
    jwtSecret
)
...do something to pass value to the next function
}, )

CodePudding user response：

You can use res.locals to do that

An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any).

So in your case

router.get(
  "/someurl",
  (req, res, next) => {
    const token = req.headers.authorization.split(" ")[1]; //jwtToken
    const jwt = jwt.verify(token, jwtSecret);
    // pass to res.locals so I can get it in next() middleware
    res.locals.token = token;
    next();
  },
  (req, res, next) => {
    // inside the next() middleware
    // get token from res.locals
    const previousToken = res.locals.token;
  }
);
