推荐答案

您无法从服务器代码访问客户端文件，并且无法在用户选择文件的情况下将文件从客户端上传到服务器。出于明显的安全原因，您是否可以想象如果恶意网站可以抓取您的文件会有多危险？

You can't access client files from your server code and you can't upload files from client to server without the user choosing the file. This is for obvious security reasons, can you image how dangerous it would be if malicious sites could grab your files?
