从Java中接收来自Chrome的本地消息 [英] Receiving native messages from Chrome in Java

问题描述

我试图在chrome扩展和Java程序之间进行本地消息传递。
经过一番努力，我现在可以打开我的Java程序：

I am trying to get native messaging between a chrome extension and a Java program to work. After some struggling I now can open my Java program with:

var port = chrome.extension.connectNative('fbehost');
port.postMessage({ text: "Hello, my_application" });

但我不知道如何阅读从我的扩展程序发送的消息。我创建了一个使用textarea打开简单JFrame的程序。正如它在文档中所说的本地消息传递与stdin和stdout进行通信，我试图通过以下方式获取消息：

But I don't know how I can read the message send from my extension. I created a program which opens a simple JFrame with a textarea. As it says in the documentation that native messaging communicates with stdin and stdout, I tried to get the message with:

while(true) {
  try {
    input=br.readLine();
    tf.setAreaText(input);
  } catch(Exception e) {
  }
}

还试过：

Also tried it with:

System.in.read()

该jar被执行，但textarea保持空白。我无法在互联网上找到任何有关如何使用Java获取数据的信息。您可以帮助我吗？

The jar gets executed but the textarea stays empty. I can't find any information on the internet how to get the data in Java. Can you help me?

推荐答案

我最近无法使用任何本机讯息在Google Chrome中工作。我记得在某个地方看到，一个半最近的更新似乎阻止了Java和Chrome之间的本地消息传递的兼容性。祝你好运。

I haven't been able to get any native messaging to work in Google Chrome recently. I remember reading somewhere that a semi-recent update appeared to prevent compatibility between Java and Chrome for native messaging. Best of luck.
