FACEBOOK MESSENGER is the mobile messaging app used to communicate with your contacts. If express.static is handling the request, you need to move your middleware up: As req.body’s shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting.For example, req.body.toString() may fail in multiple ways, for example stacking multiple parsers req.body may be from a different parser. Testing middleware is subtly different. Simple cookie-based session middleware. Testing a middleware and mocking Express request.get headers. Testing that req.body is a Buffer before calling buffer methods is recommended. cookie-session. I can craft a request in 1 line of python and send you a request without that field making your code crash – arboreal84 Jul 28 '16 at 18:31 3 request.headers.host is now deprecated, instead you can use request.headers.hostname – Syam Danda Dec 8 '16 at 9:45 A lot of middleware has conditions under which it does nothing (just calls next()). Another scenario in which you might want to mock/stub the Express request and response objects is when testing a middleware function. A user session can be stored in two main ways with cookies: on the server or on the client. The order in which you use middleware in Express matters: middleware declared earlier will get called first, and if it can handle a request, any middleware declared later will not get called.
