Question

我想编写一个文件下载测试，为此，我首先上传文件，然后调用API下载上传的文件，上传成功，但下载始终失败，并显示The file "/var/www/public/uploads/dWwECsHQpcwJuYTn6uaLmPxk4uINOeYOZYiZ86Oc.jpeg" does not exist。以下是我的测试功能内容：

Storage::fake('public');
$business = factory(Business::class)->create(['owner_id' => $this->businessUser->id]);
$response = $this->jsonAs($this->businessUser,'POST', '/api/file/business', [
    'file' => $file = UploadedFile::fake()->create('invalid file.jpg'),
    'attachable_id' => $business->id,
    'attachable_type' => 'businesses'
]);

$response->assertJson(['name' => $file->hashName()]);
Storage::disk('public')->assertExists('uploads/' . $file->hashName());

$uploadRes = $response->decodeResponseJson();

$response = $this->jsonAs($this->businessUser, 'GET', '/api/file/'. $uploadRes['id'] . '/business/' .$business->id);
// This assertion always fails 
// If I dd above response, shows this message 'The file "/var/www/public/uploads/dWwECsHQpcwJuYTn6uaLmPxk4uINOeYOZYiZ86Oc.jpeg" does not exist'    
$this->assertTrue($response->headers->get('content-type') == $file->getClientMimeType());
$this->assertTrue($response->headers->get('content-disposition') == 'attachment; filename="' . $uploadRes['original_filename'] . '"');
$response->assertStatus(200);

以下是我的下载功能内容：

$attachment = Attachment::where('id', $id)->firstOrFail();
$path = public_path(). '/uploads/' . $attachment->name;

return response()->download($path, $attachment->original_filename, ['Content-Type' => $attachment->mime]);

Answer 1

确保文件位于 public / upload 目录中，并且可以使用url()函数为公共目录文件生成链接。

EX：

$attachment = Attachment::where('id', $id)->firstOrFail();
$path = url('uploads/' . $attachment->name);

return response()->download($path, $attachment->original_filename, ['Content-Type' => $attachment->mime]);

Answer 2

在下载实现中，我注意到使用了public_path函数。

public_path函数从服务容器解析，可能从public磁盘配置的实际路径创建了新路径。

Storage::fake正在设置磁盘路径并返回FilesystemAdapter，并且您要确保这是测试规范生命周期中使用的实例。

我建议尝试通过Storage门面使用FilesystemAdapter中的path方法来构造下载实现中的路径，而不是public_path帮助函数。例如：

Storage::disk('public')->path('uploads/'.$attachment->name);
