所以我正在制作连接节点服务器的chrome扩展程序。但Chrome扩展拒绝连接。我的脚本在tampermonkey中工作，它连接起来。但不是铬？ Chrome显示没有调试日志，没有任何错误。它只是没有连接到服务器。

更新：
我决定不提取并将脚本本身作为引擎包含在内。但是我仍然有并发症。谷歌扩展仍然拒绝建立连接。这是我正在尝试执行的代码：

if(client_uuid == null){
console.log("generating a uuid for this user");
client_uuid = Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1);
localStorage.setItem('client_uuid', client_uuid);
}
console.log("This is your config.client_uuid " + client_uuid);

您可以尝试包含＆＃39; WebSocket :: didConnect（）＆＃39;。 更改“readyState”＆＃39;打开＆＃39;打开＆＃39;并创建一个名为＆＃39; open＆＃39;的简单事件。并派遣活动。
这是WebSocket服务器的示例应用：https://github.com/GoogleChrome/chrome-app-samples/tree/master/samples/websocket-server
