I am trying to access req.body in express middleware in a router, however it is consoling empty req.body. However in actual data does exist. I am already using body-parser at app level but it is not working for me. Below is my code, I am trying to access req.body in authorization middleware in categories.js file
index.js
const express = require('express');
const bodyParser = require('body-parser');
//Importing Routers
const customersRouter = require('./routes/customers');
const categoriesRouter = require('./routes/categories');
const itemsRouter = require('./routes/items');
const usersRouter = require('./routes/users');
const tablesRouter = require('./routes/tables');
const ridersRouter = require('./routes/riders');
const taxtypesRouter = require('./routes/taxtypes');
const branchesRouter = require('./routes/branches');
const subscribeRouter = require('./routes/subscription');
const loginRouter = require('./routes/login');
//Importing Database Connection
//const db = require('./dbConnection');
const app = express();
app.use(bodyParser.urlencoded({extended:false}));
app.use(bodyParser.json());
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`Server is listening at port ${PORT}`));
app.use('/subscribe', subscribeRouter);
app.use('/login', loginRouter);
app.use('/client/:clientID/user/:userID/customers', customersRouter);
app.use('/:clientID/categories', categoriesRouter);
app.use('/client/:clientID/user/:userID/items', itemsRouter);
app.use('/client/:clientID/user/:userID/users', usersRouter);
app.use('/client/:clientID/user/:userID/tables', tablesRouter);
app.use('/client/:clientID/user/:userID/riders', ridersRouter);
app.use('/client/:clientID/user/:userID/taxtypes', taxtypesRouter);
app.use('/client/:clientID/user/:userID/branches', branchesRouter);
router file categories.js
const express = require('express');
const util = require('util');

const query = util.promisify(db.query).bind(db);

return cb(null, path);

try {

//Create Local Category ID
const SQL1 = `SELECT COUNT(ClientID) AS 'Categories' FROM categories WHERE ClientID = ${clientID};`;
let counter = await query(SQL1);

const localCategoryID = 'CT' ('00' counter).slice(-3);

}
else {

}
})()
}
catch (err) {

return;
}
});
module.exports = categoriesRouter;
CodePudding user response:
the body-parser module don't require to explicitly install.
Its provided under the methods express.json() and express.urlencoded().
so add
app.use(express.urlencoded({extended: true}));
app.use(express.json())
and remove
require('body-parser');
app.use(bodyParser.urlencoded({extended:false}));
app.use(bodyParser.json());
