问题描述
为解决我的问题，我在不同站点上浏览了许多文章，但没有一篇文章解决. 我正在编写一个简单的AngularJS应用程序.我对Angular很陌生.我已经编写了一个工厂方法，该方法调用$ http服务，该服务从Web api获取数据. Web api运行良好，并且按预期返回了JSON对象.
To resolve my issue I have gone through many articles on different sites, but none resolved it. I'm writing a simple AngularJS application. I'm quite new to Angular. I have written a factory method which call the $http service which gets the data from the web api. Web api is running fine and its returning the JSON object as expected.
角度代码
var app = angular.module("app", [])
.controller("controller", function ($scope, WebFactory) {
$scope.data = "data";
$scope.error = "error";
$scope.data=WebFactory.getData();
})
.factory("WebFactory", function ($http) {
var obj = {};
obj.getData = function()
{
$http({
method: "GET",
url: "http://localhost:37103/api/employee",
}).then(function success(response) {
return response.data;
})
.then(function error(response) {
return response;
});
return 'No data';
}
return obj;
});
HTML代码
<body ng-controller="controller">
data: {{data}}
<br/>
error: {{error}}
<br />
我已经花了2天的时间，但仍然不知道为什么它不起作用.
I have spent 2 days, but still dont know why its not working.

$scope.data = "data";
$scope.error = "error";
$scope.data = {}
WebFactory.getData().then(function success(response) {
$scope.data = response.data;
});
})
.factory("WebFactory", function ($http) {
var obj = {};
obj.getData = function()
{
return $http({
method: "GET",
url: "http://localhost:37103/api/employee",
})
}
return obj;
});
