var express = require("express");
var fs = require("fs");
var app = express();


app.post("/", function(req, res){
  var date = Date.now();
  var fileName = "POST.json";

  console.log("POST / @" + date);

  fs.writeFile(fileName, JSON.stringify({ "HEADERS": req.headers}, undefined, 2), function fileWriteComplete(err){
    if(err){
      console.log("     Error writing to file " + err);
    } else{
      console.log("     File saved " + fileName);
    }
  });

  res.send("Ok");
});


app.listen(3000, function(){
  console.log("App listening on port 3000");
});
