Expressdaten zwischen Middleware ausdrücken
function middleware1(req, res, next) {
// Set data
req.dataFromMiddleware1 = "Data of Middleware 1";
// Go to next middleware
next();
}
function middleware2(req, res, next) {
console.log("We are in Middleware 2.");
// Get Data of Middleware1
console.log(req.dataFromMiddleware1);
// Go to next middleware
next();
}
// Handling Get Request '/'
app.get("/", middleware1, middleware2, (req, res) => {
return res.send(req.dataFromMiddleware1);
});
