从同一服务器调用路由会导致无限循环 [英] Calling route from same server causes an infinite loop
问题描述
开始之前
我以Laravel为例，但实际上我是用手工制作的MVC做的一个小项目，问题仍然存在，所以与框架无关.
I use Laravel as example, but I actually made a small project with hand-made MVC and the issue is still occuring, so this has nothing to do with the framework.
上下文
我使用php artisan serve，相当于php -S localhost:8000 -t public来启动我的Web应用程序.我不使用Apache(可能是个提示吗?).
I use php artisan serve, which is the equivalent of php -S localhost:8000 -t public to boot up my web app. I do not use Apache (might be a hint ?).
客户(人类)通过其Web浏览器请求页面/user.响应该端点的控制器如下所示:
The client (human) request the page /user through his web browser. Here is how the controller that responds to this endpoint looks like:
routes.php
<?php
Route::resource('user', 'UserController');
?>
UserController.php
<?php
namspace App\Http\Controller;
use Illuminate\Http\Request;
use App\User;
class UserController {
public function index( Request $request ) {
$users = User::all();
if( $request->wantsJson() ) {
return response()->json($users, 200);
}
else {
return view('user.index')->with('users', $users);
}
}
}
?>
此代码没有错，一切正常.
Nothing wrong on this code, everything works.
我想建立一个存储"机制，仅由我的api端点负责提供数据.更改如下:
I would like to set up a "store" mecanism, where only my api endpoint is responsible of providing the data. So here is the changes:
api.php
<?php
Route::group(['prefix' => 'v1'], function() {
Route::resource('user', 'UserApiController');
});
?>
UserApiController.php
<?php
namespace App\Http\Controller;
use Illuminate\Http\Request;
use App\User;
class UserApiController {
public function index() {
return response()->json(User::all(), 200);
}
}
?>
UserController.php
<?php
namespace App\Http\Controller;
use Illuminate\Http\Request;
use App\User;
class UserController {
public function index() {
return view('user.index')->with('users', User::all());
}
}
?>
重现问题
为此，如果我走了错误的路径，请纠正我，我的端点/user应该从/api/v1/user请求数据，然后将数据提供给视图并返回Http响应.所以这是我在UserController.php上修改的内容:
To do so, correct me if I go on the wrong path, my endpoint /user should request the data from /api/v1/user, and then provide the data to the view and return the Http response. So here is what I modifyied on the UserController.php:
UserController.php
<?php
namespace App\Http\Controller;
use Illuminate\Http\Request;
use App\User;
use GuzzleHttp\Client;
class UserController {
public function index() {
$client = new Client;
$response = $client->get(url('/api/v1/user'));
return view('user.index')->with('users', User::all());
}
}
?>
对于我来说，端点将接收来自客户端(人类)的请求，然后向api端点发送第二个请求，获取json数据，解析(使用$data = $response->getBody()->getContents(); GuzzleHttp方法)，然后将其提供给视图(使用return view('user.index')->with('users', $data);.
For me, the endpoint will receive the request from the client (human), then send a second request to the api endpoint, fetch the json data, parse it (using $data = $response->getBody()->getContents(); GuzzleHttp method), and then provide it to the view (using return view('user.index')->with('users', $data);.
问题
服务器实际上是无限循环的，我不了解该过程中发生了什么故障.请注意，从另一台服务器调用api(例如https://ipapi.co/json可以很好地工作).
The server actually infinite loop and I do not understand what is failing in the process. Note that calling an api from another server (for example https://ipapi.co/json works totally fine).
有人可以给我提示造成冻结的原因吗?
Can someone give me a hint on what is causing this freeze?
推荐答案
这与PHP处理请求的方式绝对相关.我通过设置Apache配置httpd.conf将项目植在相同的位置localhost:8000上，并且它可以正常工作，我可以跨路线发出请求.
This is definitively related to the way PHP handles requests. I rooted my project on same location localhost:8000 by setting Apache configuration httpd.conf and it is working, I can make requests across my routes.
如果有什么灵魂可以在这里粘贴有关我在PHP Web服务器上的请求所发生的情况的技术详细信息...
If any kind soul could paste here a technical detail on what is happening with my requests on PHP web server...
