推荐答案

可以，但不能使用典型的浏览器.浏览器被沙盒化，无法访问本地文件系统(cookie 除外)，因此恶意网站无法读取/写入您的硬盘.据我所知，没有办法覆盖这种行为(除了编写自己的浏览器).

Yes you can, but not with a typical browser. Browsers are sandboxed to not have access to the local file system (except cookies) so that malicious sites can't read from / write to your hard drive. As far as I know there is no way to override this behvior (short of writing your own browser).

但是，这可以使用 Node.js 在 JavaScript 中完成.它作为进程而不是在浏览器窗口中运行，并且可以访问文件系统.具体来说，已经有一个用于串行通信的 npm 模块(节点库):https://github.com/voodootikigod/node-serialport

However, this can be done in JavaScript using Node.js. It runs as a process rather than in a browser window and can access the file system. Specifically, there is already an npm module (node library) for serial communication: https://github.com/voodootikigod/node-serialport

或者，您可以随时启动本地 Web 服务器(通过 node.js、php、rails 等).Web 服务器可以访问文件系统，因此应该可以访问串行端口.

Alternatively, you could always just spin up a local web server (via node.js, php, rails, etc). Web servers can access file systems, and therefore should be able to access serial ports.

希望这会有所帮助.
