是否可以在Express中console.log GET请求？

Question

I am trying to test the results of my crud operations for a node.js/express app on the console but it doesn't seem to work for GET only for POST.

I have this function:

   app.get('/', (req, res) => {
    db.collection('cars').find().toArray(function(err, results) {
    console.log(results)
    })
   })

But I am unable to find a way to execute and retrieve the results in the console. How can I do this?

Answer 1

try doing this:

db.open(function(err,db){ // <------everything wrapped inside this function
         db.collection('cars', function(err, collection) {
             collection.find().toArray(function(err, results) {
                 console.log(results);
             });
         });
     });

Answer 2

that looks like MongoDB to me, and if it is, then I don't think the cursor.toArray() method takes a callback function at all. Instead it iterates over all results and exhausts the cursor for you.

try console.log(db.collection('cars').find().toArray()); .
