Laravel RESTful控制器参数

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:

  1. 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?

  2. 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()Input::json(),但我没有运气。

  3. 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'];

一样使用

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) {
    //
});
