Node.js，未调用处理程序回调

Question

这是一个简单的代码示例：

var https = require('https');
var fs = require('fs');

var options = {
  key: fs.readFileSync("./ssl/key.pem"),
  cert: fs.readFileSync("./ssl/cert.pem")
};

https.createServer(options, function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}).listen(443);

对 localhost:443 的所有请求都会导致无限等待。

我通过以下方式运行此示例：“sudo nodejs https.js”

未观察到错误/警告。端口 443 处于“侦听”状态。 https://www.dropbox.com/s/uchpbn0ifacmf4x/node.jpg?dl=0

问题在我的 linux 和 windows 机器上重现。

我还尝试了名为“pem”的节点库，结果相同。

http 在我的环境中运行良好。

节点版本：0.10.33

您能帮我解决问题吗？我可以激活更多调试吗？

Answer 1

呵呵……

此问题的根本原因是请求“http://localhost:443”而不是“https://localhost”。

感谢nodejs https server doesn't respond
