[nodejs] How to print the error stack when I request by ajax

I guess you want to have the stack trace displayed on the client (which is ti be
avoided, since you may give away details of your system that might be exploited by
malicious users).

Anyway, this would do:

require("http").createServer(function (req, res) {
    try {
      xxx;
    } catch(e) {
      res.writeHead(500, { "Content-Type": "text/plain"});
      res.write("Status: " + res.statusCode + "\n");
      res.write("Message: " +e.message + "\n");
      res.write("Stacktrace: " + e.stack + "\n");
      res.end();
      return;
    }
    res.writeHead(200, { "Content-Type": "text/plain"});
    res.end("OK");
}).listen(8080, "127.0.0.1");

console.log("Server running at http://127.0.0.1:8080/");

Do you have access to the server as well? If so, view the error in the
console.

If you have no control of the server then you're most likely out of luck.
