我的目的是在 AngularJS 中使用 REST web 服务，我现在正在做一些试验。下面的代码不起作用并抛出以下异常。你能帮我找出问题吗？
Thanks in advance.
提前致谢。
function getUsersFromLocal($scope,$http)
{
$http.get('http://localhost:8080/people').
success(function(data) {
$scope.data = data;
});
return data;
}
Error is: TypeError: Cannot read property 'get' of undefined at getUsersFromLocal.
错误是：类型错误：无法在 getUsersFromLocal 读取未定义的属性“get”。
The service is accessible and I tested it through some REST clients.
该服务是可访问的，我通过一些 REST 客户端对其进行了测试。

If I understood correctly getUsersFromLocalfunction is inside controller, basically the function parameters are killing the $scope, $httpobject existence, You need to remove them from parameter & Also removed the return statement which was outside $httpwhich won't work in anyways.
如果我理解正确，getUsersFromLocal函数在控制器内部，基本上函数参数正在杀死$scope,$http对象存在，您需要将它们从参数中删除，并且还删除了外部的 return 语句，$http无论如何它都不起作用。

代码
app.controller('mainCtrl', function() {
$scope.getUsersFromLocal = function() {
$http.get('http://localhost:8080/people').
success(function(data) {
$scope.data = data;
});
};
$scope.getUsersFromLocal(); //call ajax method
});

Try like this , this way i found on w3school.
像这样尝试，这是我在 w3school 上找到的。
var app = angular.module('myApp4', []);
app.controller('customersCtrl', function($scope, $http) {
$http.get("http://www.w3schools.com/angular/customers.php")
.success(function(response) {
$scope.data= response.records;
});
});

if getUsersFromLocalis not a controller or service, and you are invoking this function manually, you should pass $httpand $scopeobjects to it, like this
如果getUsersFromLocal不是一个控制器或服务，而且你手动调用这个函数，你应该通过$http和$scope对象，就像这样
module.controller('TestController', function($scope, $http) {
function getUsersFromLocal($scope,$http) {
$http.get('http://localhost:8080/people').
success(function(data) {
$scope.data = data;
});
}
getUsersFromLocal($scope, $http); // pass this services manually
});
