沒有在網上看到很多關於Angular2和SailsJS Resourceful Pub/Sub場景的東西。我正在嘗試觀看新記錄的模型並將它們顯示在我的Angular2應用程序中。我正在使用angular2-sails模塊。下面的代碼成功地將數據導入我的角度應用程序,但需要刷新頁面以獲取新數據。我們的目標是在不刷新頁面的情況下實時獲取數據。SailsJS - Angular2 - 足智多謀的Pub/Sub
帆控制器操作:
newCall: function(req, res) {
if (!req.isSocket)
return res.badRequest;
Call.create({
payload: req.body
})
.exec(function (err, newCall){
if (err) return res.negotiate(err);
Call.publishCreate(newCall);
res.ok(newCall);
});
},
getCalls: function(req, res) {
Call.find()
.then(function(calls) {
Call.watch(req.socket);
console.log(req.socket.id + ' is now watching for changes to Calls model');
res.send(calls);
})
.catch(function(err) {
console.log(err);
});
}
Angular2組件:
ngOnInit() {
let sails = this._sailsService;
sails.connect("http://localhost:1337")
sails.get('/socket/getCalls')
.subscribe(
(resData) => { this.calls = resData.data.length},
(error) => { console.log("oooops, error occured") },
() => { console.log("we are finished") }
)
}
