node.js - 错误: Can't set headers after they are sent using web-terminal

Question

我试图使用网络终端..当我运行我的服务器代码时，出现以下错误

Web-terminal accessible at http://127.0.0.1:1337/terminal

http.js:691
throw new Error('Can\'t set headers after they are sent.');
      ^
Error: Can't set headers after they are sent.

at Object.oncomplete (fs.js:107:15)

我的服务器端代码是:

 var http        = require("http"),
    terminal    = require("web-terminal");

var app = http.createServer(function (req, res) {
    res.writeHead(200, {"Content-Type": "text/plain"});
    res.end("Hello World\n");
});

app.listen(1337);
console.log("Server running at http://127.0.0.1:1337/");

terminal(app);
console.log("Web-terminal accessible at http://127.0.0.1:1337/terminal");

如何解决这个问题。

我找到了这个问题的解决方案...我使用“connect”模块来创建服务器..

var connect = require('connect');
var terminal = require('web-terminal');
terminal(connect.createServer(
    connect.static(__dirname)
).listen(8080));

还将“web”目录的内容从 Web 终端包复制到您的服务器目录中...
现在您可以从 http://'servername':8080/index.html 访问 Web 终端
