laravel 4 从不同文件夹下载文件

Question

大家好，我的项目下载页面需要一些帮助，因为我需要一个从不同文件夹获取文件的下载页面，所有文件夹都在 public 路径中，你有一些吗为此，我正在使用一个类似于下面 link 的页面，只是忽略了另一个按钮。

Download Page

我刚刚尝试了 ajax 但它不起作用

这是我的观点：

@include('partials.navbar')

    $.ajax({

          var dload = JSON.parse(msg)[0];
          console.log(dload)

我的控制器：

public function dloadFile($id)
    {
        $files = Files::where('id',$id)
                     ->get();
        return json_encode($files);
    }

    public function getDownload()
    {
        $id = Input::get('id');
        $files = Files::where('id',$id)
                     ->first();
        $ftype = $files->file_type = Input::get('type');
        $filename = $files->upload = Input::file('filename');
        $file= public_path(). "uploads/{$ftype}";

        $headers = array(
              'Content-Type: => application/pdf',
            );

        return Response::download($file, '{$filename}', $headers);


    }

我的路线：

Route::get('/downloadfile/{id}', 'FileController@dloadFile');
Route::get('/download', array('uses' => 'FileController@getDownload'));

任何想法都非常感谢提前致谢！

无需使用Ajax下载。有我的代码可以下载产品 image.in 查看文件有下载 link.

<a data-id="{{ $product->id }}" href="/productCRUD/{{$product->id}}/download" class="btn btn-primary btn-xs dload-button" ><i class="fa fa-download">Download</i></a>

在routes.php

Route::get('productCRUD/{product}/download', 'ProductCRUDController@download');

在productCRUDController.php

public function download($id)
{

    $files = Product::where('id',$id)
                 ->first();
    $ftype = $files->file_type = Input::get('type');
    $fullPath= public_path(). "/uploads/{$files->filePath}";
    $headers = array(
          'Content-Type: => application/jpg',
        );
    return  Response::download($fullPath,$files->filePath, $headers);

}

使用此代码，当您单击下载 link 时，您会在下载文件夹中获得文件。
