Download file with php after login with php code
提问by Tommy Tang
i have two links one for login (www.xxx/login/) one for download file (www.xxx/download/)
我有两个链接，一个用于登录（www.xxx/login/），一个用于下载文件（www.xxx/download/）
if already login, link to www.xxx/download/ will download file automatically, if not the page will redirect to www.xxx/login/
如果已经登录，链接到 www.xxx/download/ 将自动下载文件，否则页面将重定向到 www.xxx/login/
So how can i write the php code? to login first then go to download file
那么如何编写php代码呢？先登录然后去下载文件

If you are working on Laravel provided login functionality then this is default provided by Laravel.
如果您正在使用 Laravel 提供的登录功能，那么这是 Laravel 默认提供的。
You can check this here
你可以在这里查看
Illuminate\Foundation\Auth\AuthenticatesUsers
This is the traitand check function sendLoginResponse. Below is the code written in sendLoginResponsefunction:-
这就是trait检查功能sendLoginResponse。下面是写在sendLoginResponse函数中的代码：-
/**
* Send the response after the user was authenticated.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
protected function sendLoginResponse(Request $request)
{
$request->session()->regenerate();
$this->clearLoginAttempts($request);
return $this->authenticated($request, $this->guard()->user())
?: redirect()->intended($this->redirectPath());
}
If you are using custom login functionality follow this.
如果您使用自定义登录功能，请遵循此操作。

you just need the middleware
你只需要中间件
so add the _constructmethod in top of controller
所以_construct在控制器顶部添加方法
public function __construct()
{
$this->middleware('auth');
}
public function dowloadMethod($fileName)
{
//your code
}
if You are using the Closuremethod in route
如果您Closure在路由中使用该方法
Route::get('YourdowloadUrl/{fileName}',function($fileName)
{
//yourcode goesrhere
}
)->middleware(['web', 'auth']);
