1. url.parse(网址): 将字符串解析成对象.

技术分享

1-1) 一个参数 : 或者参数1, false(默认), false(默认)

var url = require(‘url‘);

console.log(url.parse("http://www.baidu.com:8080/list?c=Cate&a=index#main"));
console.log(url.parse("https://user:pass@sub.host.com:8080/p/a/t/h?query=string#hash"));
console.log(url.parse("http://127.0.0.1/culture/action.php?c=HCourseProxy&a=displaySuccess&courseId=4"));

1-2) 两个参数或者是参数1, true, false(默认)

如果第二个参数设置为 true. 那么 query属性就会调用 querystring模块的方法 ,生成一个对象.

1 var url = require(‘url‘);
2 
3 console.log(url.parse("http://www.baidu.com:8080/list?c=Cate&a=index#main", true));
4 console.log(url.parse("https://user:pass@sub.host.com:8080/p/a/t/h?query=string#hash", true));
5 console.log(url.parse("http://127.0.0.1/culture/action.php?c=HCourseProxy&a=displaySuccess&courseId=4", true));

1-3) 三个参数: 参数1 , 参数2(布尔值), true

对于不知道是什么协议的时候, 如果想解析//www.baidu.com:8080/list?c=Cate&a=index#main 这种 , 就可以将第三个参数设置为 true.

1 var url = require(‘url‘);
2 
3 console.log(url.parse("//www.baidu.com:8080/list?c=Cate&a=index#main"));
4 console.log(url.parse("//www.baidu.com:8080/list?c=Cate&a=index#main", false, true));
5 
6 console.log(url.parse("//baidu.com:8080/list?c=Cate&a=index#main"));
7 console.log(url.parse("//baidu.com:8080/list?c=Cate&a=index#main", false, true));

2. url.format(对象) 将对象转成字符串

var url = require(‘url‘);

console.log(url.format({
  protocol: ‘https:‘,
  slashes: true,
  auth: ‘user:pass‘,
  host: ‘sub.host.com:8080‘,
  port: ‘8080‘,
  hostname: ‘sub.host.com‘,
  hash: ‘#hash‘,
  search: ‘?query=string‘,
  query: ‘query=string‘,
  pathname: ‘/p/a/t/h‘,
  path: ‘/p/a/t/h?query=string‘,
  href: ‘https://user:pass@sub.host.com:8080/p/a/t/h?query=string#hash‘ }));

 1 var url = require(‘url‘);
 2 
 3 console.log(url.resolve("http://www.runoob.com/", "nodejs/nodejs-path-module.html"));
 4 console.log(url.resolve("http://www.runoob.com/", "/nodejs/nodejs-path-module.html"));
 5 
 6 console.log(url.resolve("http://www.runoob.com/list/", "nodejs/nodejs-path-module.html"));
 7 console.log(url.resolve("http://www.runoob.com/list/", "/nodejs/nodejs-path-module.html"));
 8 console.log(url.resolve("http://www.runoob.com/list", "/nodejs/nodejs-path-module.html"));
 9 
10 console.log(url.resolve("http://www.runoob.com/list/cate/", "../nodejs-path-module.html"));
11 console.log(url.resolve("http://www.runoob.com/list/cate", "../nodejs-path-module.html"));
