在用户突然从我的应用程序切换到另一个应用程序或重新启动手机后,我正面临着从先前登录中读取已设置数据的问题。我成功登录后设置的数据会保存在SQLite数据库中。在Android登录时从SQLite离子读取数据
.controller('LoginCtrl', function($scope, $ionicPopup, $state,$http,ServerEndPoint,localStorageService,$cordovaGeolocation,$ionicActionSheet,dataShare,$ionicPush,loading,$rootScope,$cordovaSQLite) {
$scope.data = {};
//Does not work
$scope.init = function()
{
$scope.load();
};
if(localStorageService.get("tradie_id") !== null && localStorageService.get("phone_no") !== null) {
$state.go('menu.map');
}
//This is called from login form submit button click
$scope.authenticateUser = function(loginForm){
//Authenticating user from the server, after successful login
//This one works
$scope.addInfo(res.data.user_id,res.data.first_name,res.data.phone_no,status);
$state.go('menu.map');
}
$scope.addInfo = function(user_id,first_name,phone_no,status){
var query = "INSERT INTO user_data(user_id,first_name,phone_no,status) VALUES(?,?,?,?)";
$cordovaSQLite.execute(db,query,[user_id,first_name,phone_no,status]);
$scope.load();
}
$scope.load = function(){
$scope.alldata = [];
$cordovaSQLite.execute(db,"SELECT * FROM user_data").then(function(result){
if(result.rows.length)
{
for(var i=0;i<result.rows.length;i++)
{
$scope.alldata.push(result.rows.item(i));
}
localStorageService.set("user_id", $scope.alldata[0].tradie_id);
localStorageService.set("first_name", $scope.alldata[0].first_name);
localStorageService.set("phone_no", $scope.alldata[0].phone_no);
}else
{
console.log("No data found");
}
},function(error){
console.log("error "+err);
})
}
})
任何建议或指针样品源代码是高度赞赏。我使用的离子版本1.
