我担心我的Firefox插件打开套接字时遇到问题.我的目标是让我的插件监听端口,Python脚本会偶尔发送一个短字符串来进行操作.

我已经检查过并且没有防火墙正在运行,如果我在启动这个插件之前设置netcat来监听我想要的端口,它的行为会有所不同(它将打印"打开的端口!").不幸的是我真的想让插件成为监听器/服务器.

const {Cu,Cc,Ci} = require("chrome");
var tcpSocket = Cc["@mozilla.org/tcp-socket;1"].createInstance(Ci.nsIDOMTCPSocket);
var socket = tcpSocket.open("127.0.0.1", 64515);
socket.ondata = function (event) {
    console.log('port received data!!!');
    if (typeof event.data === 'string') {
        console.log('Got: ' + event.data);
    }
}
socket.onopen = function() {console.log('opened port!');}
socket.onerror = function(event) {
    console.log('port error!');
    console.log(event.data)
}
socket.onclose = function() {console.log('port closed!');}
socket.ondrain = function() {console.log('port drained!');}

现在虽然立即输出是:

console.log: my-addon: port error!
console.log: my-addon: DOMError {}
console.log: my-addon: …
