您不需要在routes.php中使用任何其他配置，如果您遵循此指南，一切都将正常工作:

You don't need to use any other config in routes.php, everything will work just fine if You follow this guide:

最简单的解决方案是创建名为api_token的列是users表.然后，当尝试从android设备访问资源时，只需将?api_token=<token>添加到您的URL中，其中<token>是users表中的api_token列.

The easiest solution would be to create column named api_token is users table. Then when trying to access resource from android device, just add ?api_token=<token> to Your URL, where <token> is a api_token column in Your users table.

例如: domain.com/storage/Asset/Media/1/2?api_token=123hello4secret

系统将尝试使用api_token == 123hello4secret搜索用户记录，因此只需将123hello4secret放入您的用户api_token字段中即可.

System will try to search for user record with api_token == 123hello4secret, so just put that 123hello4secret into Your user api_token field.

如果您想知道为什么要api_token作为列名，答案在这里:

If You wonder why You should api_token as column name, the answer is here: https://github.com/laravel/framework/blob/2a38acf7ee2882d831a3b9a1361a710e70ffa31e/src/Illuminate/Auth/TokenGuard.php#L45 Laravel will try to authorize You using api_token if it is found in request fields.

您还可以使用HTTP标头通过令牌进行授权:
标头示例:

Also You can use HTTP headers to authorize with token:
Header example:

Authorization: Bearer 123hello4secret
