Laravel从存储中检索图像以进行查看 [英] Laravel Retrieve Images from storage to view

问题描述

我正在使用以下代码存储上传的文件

I am using below code to store the uploaded file

 $file = $request->file($file_attachment);
        $rules = [];
        $rules[$file_attachment] = 'required|mimes:jpeg|max:500';
        $validator = Validator::make($request->all(), $rules);
        if ($validator->fails()) {
            return redirect()->back()
                ->with('uploadErrors', $validator->errors());
        }

        $userid = session()->get('user')->id;
        $destinationPath = config('app.filesDestinationPath') . '/' . $userid . '/';
        $uploaded = Storage::put($destinationPath . $file_attachment . '.' . $file->getClientOriginalExtension(), file_get_contents($file->getRealPath()));

上传的文件存储在 storage/app/2/filename.jpg

我想向用户显示他上传的文件.我该怎么办?

I want to show back the user the file he uploaded. How can i do that?

$ storage =存储::: get('/2/filename.jpg');

$storage = Storage::get('/2/filename.jpg');

我收到不可读的文本.我可以确认该文件已被读取.但是如何将其作为图像显示给用户.

I am getting unreadable texts. I can confirm that the file is read. But how to show it as an image to the user.

希望我的观点清楚.

工作解决方案

display.blade.php

display.blade.php

<img src="{{ URL::asset('storage/photo.jpg') }}" />

web.php

Route::group(['middleware' => ['web']], function () {
    Route::get('storage/{filename}', function ($filename) {
        $userid = session()->get('user')->id;
        return Storage::get($userid . '/' . $filename);
    });
});

推荐答案

无法像您所说的那样公开访问文件，然后像这样读取文件

File not publicly accessible like you said then read file like this

$userid = session()->get('user')->id;
$contents = Storage::get($userid.'/file.jpg'); 

假设您的文件位于路径storage/app/{$userid}/file.jpg 且默认磁盘为local选中config/filesystems.php

Assuming your file is at path storage/app/{$userid}/file.jpg and default disk is local check config/filesystems.php

可公开访问的文件

File publicly accessible

如果要使文件可公开访问，则将文件存储在此storage/app/public文件夹中.您可以在其中创建子文件夹并将其上传到该文件夹​​.将文件存储在storage/app/public中后，您只需创建一个符号链接，laravel就会使用artisan命令.

If you want to make your file publicly accessible then store file inside this storage/app/public folder. You can create subfolders inside it and upload there. Once you store file inside storage/app/public then you have to just create a symbolic link and laravel has artisan command for it.

php artisan storage:link

这将创建storage/app/public到public/storage的符号链接.意味着现在您可以像这样访问文件

This create a symbolic link of storage/app/public to public/storage. Means now you can access your file like this

$contents = Storage::disk('public')->get('file.jpg'); 

此处文件物理路径位于storage/app/public/file.jpg，并且通过符号链接路径public/storage/file.jpg

here the file physical path is at storage/app/public/file.jpg and it access through symbolic link path public/storage/file.jpg

假设您有子文件夹 storage/app/public/uploads，您可以在其中存储上传的文件，然后可以像这样访问它

Suppose you have subfolder storage/app/public/uploads where you store your uploaded files then you can access it like this

$contents = Storage::disk('public')->get('uploads/file.jpg');

当您在公共文件夹中上传时，您可以在视图中访问它

When you make your upload in public folder then you can access it in view

echo asset('storage/file.jpg'); //without subfolder uploads

echo asset('storage/uploads/file.jpg');
