使用服务和http时收到错误Error: [$injector:undef]
。在更改为此特定错误建议的所有更改后,我无法找到原因。请检查以下代码
mainApp.controller('deviceDataController',["$scope","mainService", function ($scope,mainService) {
console.log(mainService);
mainService.deviceDataVar().success(function (data) {
// $scope.deviceDetails = mainService.devices;
console.log(data);
});
}]);
mainApp.factory("mainService",["$http", function ($http) {
angular.forEach(deviceIds, function(value, key) {
var timezone = user_response.timezone;
var DataUrl = LAX_API + "device_info.php?deviceid=" + value + "&limit=288&timezone=" + timezone;
return {
deviceDataVar: function () {
return $http.get(DataUrl).success(function (response) {
devices = response.data;
return devices;
}).error(function (data, status, headers, config) {
// log error
console.log(data)
});;
}
}
});
}]);
请帮我解决我的问题
谢谢!

您的工厂声明无效。
你的工厂应该是这样的:
mainApp.factory("mainService", function ($http, $q) {
/* generate single link for deviceID */
function getDevice(value){
var timezone = user_response.timezone;
var dataUrl= LAX_API + "device_info.php?deviceid=" + value + "&limit=288&timezone=" + timezone;
return $http.get(dataUrl);
}
function deviceDataVar(){
// map method will transform list of deviceIds into a list of $http promises
var allRequests = deviceIds.map(getDevice);
// this promise will wait for all calls to end, then return a list of their results
$q.all(allRequests).then(function(arrayOfResults) {
// here you will have all responses, you just need to agregate them into single collection.
// secondly you will need to wrap them into a promise and return
return ...
});
}
/* Return only public methods, at the end */
return {
deviceDataVar: deviceDataVar
}
});
(我在飞行中写这个,所以可能会有很少的错误:),但是概念是正确的)
