我使用Cordova和Firebase创建应用程序。
我所做的众多功能之一就是这个功能:
function searchForGameRound() {
var ref = new Firebase("https://grootproject.firebaseio.com/Users/");
// Dit is de query naar Firebase toe (kan je vergelijken met een query als bij SQL)
var query = ref.orderByChild("gameSearching").equalTo(true);
console.log('spelen');
// Hierbij geef ik aan dat hij dit enkel 1x mag doen. Dit voorkomt dat hij dit op elk child gaat uitvoeren (wat meerdere games maakt).
query.once("value", function (data) {
console.log('spelen', data.val());
if (data.val() === null) {
updateData(('Users/' + you + '/'), {gameSearching: true});
return;
}
var alreadyInCurrentGame;
var object = data.val();
var user1 = Object.keys(object)[0];
var user2 = Object.keys(object)[1];
// Als je het zelf bent
if (you == user1) {
if (user2) {
opponent = user2;
} else {
updateData(('Users/' + you + '/'), {gameSearching: true});
return;
}
} else {
opponent = user1;
}
console.log(opponent, 'opponent found');
// Hierbij gaat hij kijken of er al een currentgame bestaat met deze user
var ref = new Firebase('https://grootproject.firebaseio.com/Users/' + you + '/currentGames/' + opponent + '/');
ref.once("value", function (snapshot) {
if (!snapshot.val() === null) {
console.log(snapshot.val(), ' bestaat al');
alreadyInCurrentGame = true;
}
}, function (errorObject) {
console.log(errorObject.error);
});
// Als alles goed is, gooit hij er data in.
if (!alreadyInCurrentGame) {
console.log('spel gevonden');
var game = new Firebase("https://grootproject.firebaseio.com/Games/");
game.on("value", function (data) {
var length = Object.keys(data.val()).length;
for (var i = 0; i < length; i++) {
games.push(Object.keys(data.val())[i]);
}
game1 = Math.floor(Math.random() * 4);
game2 = Math.floor(Math.random() * 4);
game3 = Math.floor(Math.random() * 4);
while(game1 == game2){
game2 = Math.floor(Math.random() * 4);
}
while(game2 == game3){
game3 = Math.floor(Math.random() * 4);
}
console.log(games, 'games');
game1 = games[game1];
game2 = games[game2];
game3 = games[game3];
console.log(game1);
console.log(game2);
console.log(game3);
var url = 'https://grootproject.firebaseio.com/Users/' + opponent + '/currentGames/' + you + '/';
var fir = new Firebase(url);
fir.set(
{
round1: {score: '-', game: game1},
round2: {score: '-', game: game2},
round3: {score: '-', game: game3}
}
);
url = 'https://grootproject.firebaseio.com/Users/' + you + '/currentGames/' + opponent + '/';
fir = new Firebase(url);
fir.set(
{
round1: {score: '-', game: game1},
round2: {score: '-', game: game2},
round3: {score: '-', game: game3}
}
);
url = 'https://grootproject.firebaseio.com/Users/' + you + '/';
fir = new Firebase(url);
fir.update(
{gameSearching: false}
);
console.log(opponent, ' opponent');
url = 'https://grootproject.firebaseio.com/Users/' + opponent + '/';
fir = new Firebase(url);
fir.update(
{gameSearching: false}
);
});
} else {
updateData(('Users/' + you + '/'), {gameSearching: true});
}
}, function (err) {
console.log(err, 'error');
});
}
我的Firebase规则:
{
"rules": {
".read": true,
".write": true,
"Users": {
".indexOn": "gameSearching"
}
}
}
似乎console.logs在他使用Firebase时没有显示(该功能也不会这样做)。
我得到的唯一的console.log是第一个console.log('spelen')
。对我来说有什么奇怪的,因为在我的电脑上工作正常。
此功能不是唯一一个无法正常工作的功能。每当我使用Firebase在手机上检索某些数据时,它都无法正常工作。
我使用的是最新版本的Cordova和Firebase版本2.0.4
有什么想法吗?
它似乎仅在我登录应用程序时才有效。当我已经登录到firebase(firebase.getAuth())时,该函数将无法工作,我将无法从firebase中检索任何数据。
答案 0 :(得分:1)
似乎没有使用authWithPassword或unauth函数,firebase没有建立连接。
我在应用程序启动时使用 Firebase.goOnline(); 解决了我的问题;
document.addEventListener("deviceready", function () {
Firebase.goOnline();
}
