如果node.js应用程序的客户端都共享同一个事件队列，node.js如何跟踪哪些上下文事件所属？
下面是一个例子来说明我所说的：如果node.js应用程序的客户端都共享同一个事件队列，node.js如何跟踪哪些上下文事件所属？,node.js,Node.js,下面是一个例子来说明我所说的： var BlueBirdPromise = require('bluebird'); function getFriendsList(user_id) { //return Promise to a list of this user's friends that gets fulfilled after doing some io with a database }; function getFriendRequestsList(user_id){ /
var BlueBirdPromise = require('bluebird');
function getFriendsList(user_id) {
//return Promise to a list of this user's friends that gets fulfilled after doing some io with a database
};
function getFriendRequestsList(user_id){
//return Promise to a list of this user's friend requests that gets fulfilled after doing some io with a database
};
router.get('/homepage', function (req, res) {
BlueBirdPromise.coroutine(function* () {
var lists = yield BlueBirdPromise.props({
friends_list: getFriendsList(req.user_id),
friend_requests_lists: getFriendRequestsList(req.user_id)
});
return lists;
})()
.then(function (lists) {
res.render('homepage', {
lists: lists
});
})
.catch(function (error) {
console.log(error);
res.render('homepage', {
lists: { friends_list: [], friend_requests_list: [] }
});
});
});
