在Node.JS中迭代对象以获取HTTP响应

Question

I have an object array in Node.JS and I wish to response.write(); it to the screen, I can manage to get the first object out but the loop stops and only the first is outputted, can anybody point me in the right direction...

db.collection('todo', function(err, collection){            
                    collection.find(function(err, cursor) {
                        cursor.each(function(err, doc) {
                            for(docs in doc){
                                if(docs == "_id"){

                                }else{
                                    var test = docs + " : " + doc[docs];


                                }

                            }
                            data = data.toString("utf8").replace("{{TEST}}", test);
                            response.write(data);
                            response.end(); 
                        })                    
                    });
                });

Answer 1

Move response.end() out of the loop. That should do it.

Answer 2

You need to change response.end(data); to response.write(data);

Note that this will asynchronously append to the stream going to the user.

If you plan to dump them all at once you can also try:

cursor.toArray(function (err, docs) { 
  /** run a for loop over each doc in docs **/
})
