我有这两项服务：
.factory('HttpHandler', function() {
return {
loadData: function (promise) {
var self = {
data: [],
loading: true,
promise: promise
};
promise.then(function (data) {
self.data = data;
self.loading = false;
});
promise.finally(function () {
self.loading = false;
});
return self;
}
};
})
.factory('Order', ['$resource', '$filter', 'apiUrl', function ($resource, $filter, api) {
var Order = $resource(api + 'orders/:path', {
path: '@path'
}, {
recent: {
method: 'GET',
params: {
path: 'recent'
},
isArray: true
}
}, {
failures: {
method: 'GET',
params: {
path: 'failures'
},
isArray: true
}
}, {
exceptions: {
method: 'GET',
params: {
path: 'exceptions'
},
isArray: true
}
});
angular.extend(Order.prototype, {
getDescription: function () {
var rolls = 0,
cuts = 0,
skus = [],
lines = $filter('orderBy')(this.lines, 'sku');
for (var i = 0; i < lines.length; i++) {
var line = lines[i];
switch (line.type) {
case 0: // cut
cuts++;
break;
case 1: // roll
rolls++
break;
}
if (skus.indexOf(line.sku) == -1) {
skus.push(line.sku);
}
}
var description = '';
description += cuts > 0 ? cuts > 1 ? cuts + ' x cuts' : cuts + ' x cut' : '';
description += rolls > 0 && description.length > 0 ? ', ' : '';
description += rolls > 0 ? rolls > 1 ? rolls + ' x rolls' : rolls + ' x roll' : '';
description += skus.length == 1 ? ' of ' + skus[0] : '';
return description;
}
});
return Order;
}]);
如您所见，我已定义了3种不同的路径：
我有这个控制器：
.controller('CustomerServicesController', ['HttpHandler', 'Order', function (handler, Order) {
var self = this;
self.recent = handler.loadData(Order.recent({ limit: 30 }).$promise);
self.failures = handler.loadData(Order.failures({ limit: 30 }).$promise);
self.exceptions = handler.loadData(Order.exceptions({ limit: 30 }).$promise);
}])
当我运行我的应用程序时，我收到一条错误说明：
undefined不是函数
在 self.failures = handler.loadData（Order.failures（{limit：30}）。$ promise）; 的行上。 如果我注释掉2行，那么控制器就变成了：
.controller('CustomerServicesController', ['HttpHandler', 'Order', function (handler, Order) {
var self = this;
self.recent = handler.loadData(Order.recent({ limit: 30 }).$promise);
//self.failures = handler.loadData(Order.failures({ limit: 30 }).$promise);
//self.exceptions = handler.loadData(Order.exceptions({ limit: 30 }).$promise);
}])
一切正常...... 我认为它与 $ resource 有关，但我无法弄明白。 为了完整起见，这是模板文件：
<div class="row">
<a class="back" href="/"><i class="fa fa-arrow-circle-left"></i></a>

谁能告诉我为什么这不起作用？
答案 0 :(得分：0)
想出来，我在订单服务中出现语法错误。它应该是：
var Order = $resource(api + 'orders/:path', {
path: '@path'
}, {
recent: {
method: 'GET',
params: {
path: 'recent'
},
isArray: true
},
failures: {
method: 'GET',
params: {
path: 'failures'
},
isArray: true
},
exceptions: {
method: 'GET',
params: {
path: 'exceptions'
},
isArray: true
}
});
而不是
var Order = $resource(api + 'orders/:path', {
path: '@path'
}, {
recent: {
method: 'GET',
params: {
path: 'recent'
},
isArray: true
}
}, {
failures: {
method: 'GET',
params: {
path: 'failures'
},
isArray: true
}
}, {
exceptions: {
method: 'GET',
params: {
path: 'exceptions'
},
isArray: true
}
});
细微差别：）
