Laravel RESTful控制器参数 [英] Laravel RESTful controller parameters

问题描述

我正在将Laravel 4与Angular JS结合使用，以使用RESTful控制器处理$ http请求.

I'm using Laravel 4 with Angular JS to handle $http requests using RESTful controllers.

我有一个RESTful控制器UserController，它具有以下功能:

I have a RESTful controller, UserController that has the following functions:

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
}

我正在执行的$ http GET和POST请求如下:

The $http GET and POST requests I am making are below:

获取

//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
)

开机自检

data = {
   'username':username,
   'email':email,
   'password':password
}
$http.post('user', data).success(
    //do something
)

getIndex()方法可以很好地工作，尽管我不确定我是否使用了正确的过程.

The getIndex() method works just fine, although I have doubts on whether I am using the correct procedure.

鉴于上述情况，我有两个问题:

With the above mentioned, I have two questions:

1. Request::get()是从XHR GET检索参数的正确方法吗?将dataString附加到Javascript中的URL是RESTful方式发送参数的正确方法吗?

1. Is Request::get() the correct way to retrieve parameters from the XHR GET? Is appending dataString to the URL in my Javascript the correct way to send in parameters the RESTful way?

如何检索从XHR POST发送的JSON对象?我尝试了几种方法，包括Request::get()和Input::json()，但是我没有运气.

How do I retrieve the JSON object sent from my XHR POST? I have tried several methods including Request::get() and Input::json(), but I've had no luck.

谢谢.

推荐答案

您必须使用$input = Input::all()来检索使用角度$ http发送的数据.然后使用$name = $input['name'];

You have to use $input = Input::all() to retrieve data send using angular $http. Then use like $name = $input['name'];

如果您使用的是更新的Laravel 4，则使用RESTful API的最佳方法是

And if you are using updated Laravel 4, the best way to use RESTful API is,

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
        );
    }

}

在您的路线上，

Route::resource('users', 'UsersController');

在使用角度脚本时，

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(); ?>/"
    };
});

GET-获取所有用户

GET - Get all users

$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 = [];
});

GET-获取单个用户进行编辑

GET - Get single user for edit

$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

PUT - Update single user

$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

POST - Save new user

$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) {
    //
});
