Laravel文件下载

问题描述

我的Laravel 5.3应用程序中有一个方法可以返回如下文件:

I've got a method in my Laravel 5.3 application that returns a file like this:

public function show(File $file)
{
    $path = storage_path('app/' . $file->getPath());
    return response()->download($path, $file->name);
}

我正在vue.js中这样获取请求:

I'm making a get request in vue.js like this:

show (file) {
    Vue.http.get('/api/file/' + file);
}

结果是这样的:

这可能是什么问题?我希望浏览器可以下载图像.

What could be wrong here? I'm expecting that I the browser downloads the image.

-编辑-

当我dd($path);时，结果如下:/home/vagrant/Code/forum/storage/app/users/3/messages/xReamZk7vheAyNGkJ8qKgVVsrUbagCdeze.png

路线在我的api.php中:

Route::get('/file/{file}',                             'File\FileController@show');

当我将其添加到web.php时，它可以正常工作.但是我需要通过我的api来访问它！

When I add it to my web.php it's working. But I need to acces it through my api!

推荐答案

添加标题:

public function show(File $file)
{
  $path = storage_path('app/' . $file->getPath());
  if(!file_exists($path)) throw new Exception("Can't get file");
  $headers = array(
    "Content-Disposition: attachment; filename=\"" . basename($path) . "\"",
    "Content-Type: application/force-download",
    "Content-Length: " . filesize($path),
    "Connection: close"
  );
  return response()->download($path, $file->name, $headers);
}

或使用自定义下载功能必须是这样的:

ORuse custom download function must be like this :

function download($filepath, $filename = '') {
    header("Content-Disposition: attachment; filename=\"" . basename($filepath) . "\"");
    header("Content-Type: application/force-download");
    header("Content-Length: " . filesize($filepath));
    header("Connection: close");
    readfile($filepath);
    exit;
}
