自定义文件名，同时保留扩展名 [英] Custom file name while keeping extension

问题描述

遵循这部分文档:

https://laravel.com/docs/5.3/filesystem#file-uploads

我正在尝试存储文件(图像)并指定自定义文件名，但是我不想更改扩展名.

I'm trying to store a file (an image) and specify a custom file name, but I don't want to change the extension.

如果我这样做:

$request->file('avatar')->storeAs('avatars', 'custom_file_name');

文件将另存为 custom_file_name (没有扩展名)，而不是 custom_file_name.png ).

The file will save as custom_file_name (with no extension), rather than custom_file_name.png).

如何在保留原始文件扩展名的同时指定自定义文件名?

How can I specify a custom file name while keeping the original file extension?

推荐答案

您可以使用以下方法获取上传文件的扩展名:

You can get extension of uploaded file with:

$extension = $request->photo->extension();

并手动将其应用于存储的文件名.

And apply it manually to the stored file name.

UploadedFile 类还包含用于访问文件的标准路径及其扩展名的方法. extension 方法将尝试根据其内容猜测文件的扩展名.

The UploadedFile class also contains methods for accessing the file's fully-qualified path and its extension. The extension method will attempt to guess the file's extension based on its contents.
