node.js - nodejs无法建立http服务器

Question

var http = require("http");
var url = require("url");

var date = new Date();

var server = http.createServer((req,res) => {
    var reqUrl = url.parse(req.url);
    var path = reqUrl.pathname;

    if (path == "/apt/parsetime") {
        apiParseTimeHandler(req,res);
    }

    var isoTime = date.toISOString();
    res.write(isoTime);
});

function apiParseTimeHandler(req,res) {
    res.writeHead(200,{
        "Content-Type": "application/json",
    });

    var dateJson = {};
    dateJson.hour = date.getHours();
    dateJson.minute = date.getMinutes();
    dateJson.second = date.getSeconds();
    dateJson = JSON.stringify(dateJson);
    res.write(dateJson);
}

server.listen(process.argv[2]);

运行后
连接到建立的服务器总是得到 error connecting

Answer 1

因为你必须调用 res.end() 才算结束了响应。如下：

 15     res.write(isoTime);
 16     res.end();

这样就行。
