Question

嗨大家我只需要在我的项目中的下载页面上获得一些帮助，因为我需要一个下载页面，从不同的文件夹中获取文件所有文件夹都在公共路径中你对我有一些想法我正在使用一个页面就像下面的链接一样，只是忽略另一个按钮。

我刚尝试了ajax，但它不起作用

我的观点：

@include('partials.navbar')
<link rel="stylesheet" type="text/css" href="http://localhost:8000/assets/css/jquery.dataTables.min.css">
<link rel="stylesheet" type="text/css" href="http://localhost:8000/assets/css/search.css">

        <div class="form-group">

@include('partials.footer')

$(function() {
$(".dload-button").click(function(){
    var param = $(this).data('id');
    $.ajax({
        url: "/downloadfile/" + param,
        success: function(msg){
          var dload = JSON.parse(msg)[0];
          console.log(dload)
          $('#id').val(dload.id);
          $('#type').val(dload.file_type);
          $('#filename').val(dload.upload);
        },
        error:function(){
            alert("failure");
        }
    });
    });
});

我的控制员：

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感谢！

无需使用Ajax进行下载。有我的代码下载产品image.in查看文件有下载链接。

<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中

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

in 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，当您单击下载链接时，您将获得下载文件夹中的文件。
