我将使用Angular从我的API收到的数据发送到我的控制器时遇到一些问题...在代码中你可以看到有问题的评论......我做了一个$ http.get()请求我得到了我的信息,然后,在回报中,数据消失:S
void(void*)
这是我得到的:
angular.module('OurenApp.services', ['ngCookies'])
.factory('Customers', function (CONFIG, $cookies, $http) {
// Get Customers from API
var customers = [];
var req = {
method: 'GET',
url: CONFIG.APIURL + '/customers/' + $cookies.get('user_id') + '/' + $cookies.get('API_KEY'),
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
}
};
$http(req).then(function successCallback(response) {
// Set message and send data to the view
//console.log(response.data.customers);
customers = response.data.customers; // <- Here I have an array of Objects (each object is a customer)
}, function errorCallback(err) {
// Set error message
console.log(err);
})
return {
all: function () {
console.log(customers); // <- Here I have an empty object ¿?¿?¿?
return customers;
},
remove: function (customer) {
customers.splice(customers.indexOf(customer), 1);
},
get: function (customerId) {
for (var i = 0; i < customers.length; i++) {
if (customers[i].id === parseInt(customerId)) {
return customers[i];
}
}
return null;
}
};
});
离子模板假信息具有以下结构:
customers: Array[21]
0: Object
1: Object
2: Object
3: Object

__proto__: Object
4: Object

7: Object
8: Object

15: Object
16: Object
17: Object
18: Object
19: Object
20: Object
length: 21
__proto__: Array[0]
所以我想说我需要将我的对象数组转换成...任何人都可以帮助我!!谢谢:))
EDITED!
还有一个问题......如何刷新数据呢?我读到工厂只获得一次数据。但是当我添加一个新客户时,我需要重新加载新数据或者有一个按钮来重新加载页面....我尝试使用$ state但是没有用。
谢谢!
答案 0 :(得分:3)
这不是应该如何处理异步调用的方式。您应该等到完成后再从控制器返回数据。
在这种情况下,可以使用$q
来实现。基本上$http.get
会返回一个承诺。并且在解决它执行.then
第一个功能作为成功回调&amp;第二次作为错误回调。
使用$q
您希望等到承诺完成。你可以使用$q.when(promise)
再次拥有.then
函数,.then
函数在promise
对象被解析时被调用,return
一些数据被调用。此机制称为chain promise。

.factory('Customers', function (CONFIG, $cookies, $http, $q) {
// Get Customers from API
var customers = [];
var req = {
method: 'GET',
url: CONFIG.APIURL + '/customers/' + $cookies.get('user_id') + '/' + $cookies.get('API_KEY'),
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
}
};
//created promise object
var promise = $http(req).then(function successCallback(response) {
// Set message and send data to the view
//console.log(response.data.customers);
customers = response.data.customers; // <- Here I have an array of Objects (each object is a customer)
return customers;
}, function errorCallback(err) {
// Set error message
console.log(err);
return err;
})
return {
all: function () {
console.log(customers); // <- Here I have an empty object ¿?¿?¿?
//returned promise will wait till promise gets complete.
return $q.when(promise).then(function(){
return customers; //returning data to continue promise chain
});
},
remove: function (customer) {
customers.splice(customers.indexOf(customer), 1);
},
get: function (customerId) {
for (var i = 0; i < customers.length; i++) {
if (customers[i].id === parseInt(customerId)) {
return customers[i];
}
}
return null;
}
};
});
<强>控制器强>
//.then function will get call when ajax gets completed.
Customers.all().then(function(customers){
console.log(customers)
})
