user：p1 IP：:: ffff：127.0.0.1节点js中的URL

Question

在我的node.js项目的本地设置中，我有一个php页面test.php。现在，当我在浏览器中输入url http://localhost:8080/test.php时，我在控制台中收到以下错误。

[12/28/2015 12:40:15] user：p1 IP ::: ffff：127.0.0.1 URL：/test.ph 请求PHP后端（GET）时出错：错误：连接ECONNREFUSED。

我应该安装一些节点js的模块，还是我的ubuntu版本的问题？

这是整个代码：

docxtemplater = require("docxtemplater"),
querystring = require("querystring"),
callstream = require("./callstream");

pg.defaults.poolSize = 25;

  process.stderr.write("===============\n[" + (d.getMonth() + 1) + "/" + d.getDate() + "/" + d.getFullYear() + " " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds() + "] "
