Node.js url.parse() 和 pathname 属性 [英] Node.js url.parse() and pathname property

问题描述

我正在阅读一本关于 node.js 的入门书，名为 The Node Beginner Book，在下面的代码(书中给出)中，我不明白 pathname 属性挂起的意义关闭解析方法.所以我想知道它在做什么.我不清楚此方法的文档

I'm reading a getting started book on node.js called The Node Beginner Book and in the code below (given in the book) I don't understand the significance of the pathname property hanging off the parse method. So I would like to know what it is doing. The documentation for this method is not clear to me

var pathname = url.parse(request.url)**.pathname;** 

var http = require("http");
var url = require("url");
function start(route, handle) {
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;         // I don't understand the pathname property
    console.log("Request for " + pathname + " received.");
    route(handle, pathname);
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}

推荐答案

pathname 是 URL 的路径部分，位于主机之后和查询之前，包括初始斜杠(如果存在).

pathname is the path section of the URL, that comes after the host and before the query, including the initial slash if present.

例如:

url.parse('http://stackoverflow.com/questions/17184791').pathname    

会给你:

"/questions/17184791"
