在 Chrome 上的 Web Serial API 中获取连接设备的名称

[英]Get name of connected device in Web Serial API on Chrome

原文 2021-06-30 12:16:46 6 1 javascript/ google-chrome/ arduino/ serial-port

As per Chrome Platform Status Web Serial API is now state of shipping since Chrome V89.根据Chrome 平台状态Web Serial API 现在是自 Chrome V89 以来的发货状态。

I work on a Universal Serial Communication App, which allows to connect to a user selected serial port.我在开发一个通用串行通信应用程序，它允许连接到用户选择的串行端口。 After a let port = await navigator.serial.requestPort() the user selects a port from the list presented by chrome.在let port = await navigator.serial.requestPort() ，用户从 chrome 显示的列表中选择一个端口。 This list contains names for the devices.此列表包含设备的名称。 Connecting the chosen port with port.open(conSettings) is no problem.使用port.open(conSettings)连接所选端口没有问题。

But how can i get the NAME of the selected port/device (from the shown list) using the Web Serial API?但是如何使用 Web Serial API获取所选端口/设备的名称（从显示的列表中）？ This is needed to show a status like "connected to ...".这是显示“已连接到...”之类的状态所必需的。 Without this it is confusing if you have multiple tabs with different ports open.如果没有这个，如果您有多个打开不同端口的选项卡，就会令人困惑。

I found this post , from March, the 10th 2021, from reillyeon (which is a Google chromium software engineer for usb and serial).我从 2021 年 3 月，10 日，从 reillyeon（这是一个用于 USB 和串行的谷歌铬软件工程师）找到了这篇文章。 He says it is planed to add an ID to the return of getInfo() , which can be used to remember and reconnect later to a still used device.他说计划在getInfo()的返回中添加一个 ID，它可以用来记住并在以后重新连接到仍在使用的设备上。

At the end ofthis other post he writes, he plans to "introduce a random identifier" , instead of "USB product name or serial number strings" , because "concerns about fingerprinting" .在他写的另一篇文章的结尾，他计划“引入一个随机标识符” ，而不是“USB 产品名称或序列号字符串” ，因为“担心指纹识别” 。

So it looks like, at this time there is nothing and it is also not planed to return a device name.所以看起来，此时什么都没有，也不打算返回设备名称。 But when this would be implemented, it would be possible to save this ID in combination with a user supplied name for the device.但是当实现这一点时，可以将此 ID 与用户提供的设备名称结合起来保存。

My question anyhow: Is fingerpriting a problem, when the user was still requested and has allowed the access to the device?无论如何，我的问题是：当用户仍然被请求并允许访问设备时，指纹识别是否有问题？
