我正在使用RESTful控制器属性构建一个带有laravel的RESTful api.到目前为止,我已经能够使大部分工作.现在的问题是验证,我试图使用“user_id”和“签名”的亚马逊方法.
我使用PHP的’hash_hmac()’创建签名.
我使用PHP的’hash_hmac()’创建签名.
这是一个api控制器的例子
class Api_Tasks_Controller extends Api_Controller {
public $restful = true;
public function get_index($id = null) {
$this->verfiy_request();
if(!is_null($id))
{
return Response::json(array("tasks"=>"just one"),200);
}
else
{
return Response::json(array("tasks"=>"everthing"),200);
}
}
}
这是api控制器类
class Api_Controller extends Controller {
public function verify_request() {
//user id
$user_id = (int) Input::get('user_id');
//signature
$sig = Input::get('sig');
//Lookup user
$user = Sentry::user($user_id);
if($user) {
//user email
$email = $user->email;
//user api key
$api_key = $user->Metadata['api_key'];
//recreate signature
$_sig = hash_hmac("sha256",$email.$user_id,$api_key);
if($_sig === $sig) {
return Response::json(array("message"=>"Request Ok"),200);
}
else {
return Response::json(array("message"=>"Request Bad"),400);
}
}
else {
return Response::json(array("message"=>"Request not authorized"),401);
}
}
发出获取请求http://api.xyz.com/v1/tasks/1?user_id=1\u0026amp;sig=41295da38eadfa56189b041a022c6ae0fdcbcd5e65c83f0e9aa0e6fbae666cd8即使在我更改了user_id参数的值时也会返回成功的消息,该参数应使签名无效请求无效.
似乎我的verfiy_request方法没有执行.
请帮帮我
我最近也在研究这个问题,并建议使用过滤器.它可以像这样工作：
原文链接：https://www.f2er.com/laravel/137849.htmlclass Api_Tasks_Controller extends Base_Controller {
public $restful = true;
function __construct() {
// Check if user is authorized
$this->filter('before','api_checkauth');
}
// rest of the class ....
}
Route::filter('api_checkauth',function()
{
//user id
$user_id = (int) Input::get('user_id');
//signature
$sig = Input::get('sig');
try {
//Lookup user
$user = Sentry::user($user_id);
if($user) {
//user email
$email = $user->email;
//user api key
$api_key = $user->Metadata['api_key'];
//recreate signature
$_sig = hash_hmac("sha256",$api_key);
if($_sig === $sig) {
return Response::json(array("message"=>"Request Ok"),200);
}
else {
return Response::json(array("message"=>"Request Bad"),400);
}
}
else {
return Response::json(array("message"=>"Request not authorized"),401);
}
}
catch (Sentry\SentryException $e) {
$errors = $e->getMessage(); // catch errors such as user not existing or bad fields
return Response::json(array("message"=>$errors),404);
}
});
另外,谢谢你介绍我哨兵:-)
