TCP/IP socket communication in HTML5
提问by Mark
I'd like to know if my idea is even possible, but based on everything I've searched for so far, it seems like it's not possible. I would love to hear what the experts think.
我想知道我的想法是否可行，但根据我迄今为止搜索的所有内容，似乎不可能。我很想听听专家们的意见。
Goal: Interface with laboratory equipment via TCP/IP sockets using HTML/Javascript.
目标：使用 HTML/Javascript 通过 TCP/IP 套接字与实验室设备接口。
One problem is that I have no control to program the server. Therefore, I can't use HTML5 websockets. The vendor has not implemented websockets. The equipment server waits for a socket connection, and then communicates via API.
一个问题是我无法控制对服务器进行编程。因此，我不能使用 HTML5 websockets。供应商尚未实施 websockets。设备服务器等待socket连接，然后通过API进行通信。
Because HTML5 and Javascript are relatively OS-independent and are 'built' for user display, I'd like to create a browser-based program. I've found related questions and answers on SO, but they are older now, so I'm wondering what is the current technology.
因为 HTML5 和 Javascript 相对独立于操作系统并且是为用户显示而“构建”的，所以我想创建一个基于浏览器的程序。我在 SO 上找到了相关的问题和答案，但它们现在更旧了，所以我想知道当前的技术是什么。
Thanks in advance, and please let me know if you have any questions.
提前致谢，如果您有任何问题，请告诉我。

The W3C published a first draft for a 'Raw Socket' standard:
http://www.w3.org/TR/raw-sockets/
W3C 发布了“原始套接字”标准的初稿：http:
//www.w3.org/TR/raw-sockets/
I think this might be what you're looking for, but I wouldn't count on it being implemented by vendors in the near future, since it's only a first draft.
我认为这可能是您正在寻找的内容，但我不指望供应商在不久的将来会实施它，因为它只是初稿。
Another thing I found out while searching, is that chrome apparently enables tcp/ip communications in extensions (did not check this myself, so can't gurantee):
http://developer.chrome.com/apps/app_network.html
我在搜索时发现的另一件事是，chrome 显然在扩展中启用了 tcp/ip 通信（我自己没有检查过，所以不能保证）：http:
//developer.chrome.com/apps/app_network.html
If possible, you might consider writing a chrome extension (though it's not really "HTML5").
如果可能，您可以考虑编写一个 chrome 扩展程序（尽管它不是真正的“HTML5”）。

I read this as needing essentially a telnet session to your equipment.
我认为这基本上需要与您的设备进行 telnet 会话。
Currently, there's no way to do this from the browser without a plugin.
目前，没有插件就无法从浏览器执行此操作。
This question has some similar discussion: Best way to display high-speed data from a telnet interface on a web view?

Why not use the server where the HTML5/Javascript code is created. To create to connection to the device and convert this to something you can use, like websockets.
为什么不使用创建 HTML5/Javascript 代码的服务器。创建与设备的连接并将其转换为您可以使用的内容，例如 websockets。
