我正在使用带有Angular JS的Laravel 4来处理使用RESTful控制器的$ http请求。
我有一个RESTful控制器UserController
,它具有以下功能:
public function getIndex(){
//is Request::get() the correct way to get the parameter?
echo json_encode(array(
'username'=>User::countUsername(Request::get('name')),
'email'=>User::countEmail(Request::get('email'))
));
}
public function postIndex(){
//don't know how to get parameter
}
我正在制作的$ http GET和POST请求如下:
GET
//is this url the correct way to send in my parameters for GET request?
dataString = 'name='+username+'&email='+email;
$http.get('user?'+dataString).success(
//do something with returned json
)
POST
data = {
'username':username,
'email':email,
'password':password
}
$http.post('user', data).success(
//do something
)
getIndex()
方法工作正常,但我怀疑我是否使用了正确的程序。
如上所述,我有两个问题:
Request::get()
是从XHR GET检索参数的正确方法吗?是否将dataString
附加到我的Javascript中的URL以正确的方式发送RESTful方式的参数?
如何检索从XHR POST发送的JSON对象?我尝试过多种方法,包括Request::get()
和Input::json()
,但我没有运气。
提前致谢。

您必须使用$input = Input::all()
来检索使用angular $ http发送的数据。然后像$name = $input['name'];
如果您使用的是更新的Laravel 4,那么使用RESTful API的最佳方式是
控制器看起来像这样,
<?php
class UsersController extends BaseController {
/**
* Display all users.
*
* @return Response
* GET http://localhost/laravel/users
*/
public function index() {
$users = User::all();
return $users;
//return View::make('users.index')->with('users', $users);
}
/**
* Show the form for creating a new resource.
*
* @return Response
*/
public function create() {
//
}
/**
* Store a newly created resource in storage.
*
* @return Response
* POST http://localhost/laravel/users
*/
public function store() {
//
}
/**
* Display the specified resource.
*
* @param int $id
* @return Response
* GET http://localhost/laravel/users/1
*/
public function show($id) {
//
}
/**
* Show the form for editing the specified resource.
*
* @param int $id
* @return Response
*/
public function edit($id) {
//
}
/**
* Update the specified resource in storage.
*
* @param int $id
* @return Response
* PUT http://localhost/laravel/users/1
*/
public function update($id) {
//
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return Response
* DELETE http://localhost/laravel/users/1
*/
public function destroy($id) {
$user = User::find($id);
$user->delete();
return Response::json(array(
'error' => false,
'message' => 'User Deleted'),
200
);
}
}
在你的路线中,
Route::resource('users', 'UsersController');
在角度脚本使用中,
var app = angular.module('myApp', []);
// include this in php page to define root path
app.factory('Data', function(){
return {
root_path: "<?php echo Request::root(); ?>/"
};
});
获取 - 获取所有用户
$http({method: 'GET', url: Data.root_path + 'users'}).
success(function(data, status, headers, config) {
$scope.users = data.users;
}).
error(function(data, status, headers, config) {
$scope.users = [];
});
获取 - 获取单个用户进行编辑
$http({method: 'GET', url: Data.root_path + 'users/'+id}).
success(function(data, status, headers, config) {
$scope.entry = data.users[0];
}).
error(function(data, status, headers, config) {
$scope.entry = [];
});
PUT - 更新单个用户
$http.put(Data.root_path + 'users/'+entry.id, entry).
success(function(data, status, headers, config) {
//
}).
error(function(data, status, headers, config) {
//
});
POST - 保存新用户
$http.post(Data.root_path + 'users', entry).
success(function(data, status, headers, config) {
//
}).
error(function(data, status, headers, config) {
//
});
删除 - 删除用户
$http.delete(Data.root_path +'users/'+id)
.success(function(response) {
//
})
.error(function(response) {
//
});
