javascript - 如何在nodejs url解析中包含端口

Question

嗯...我有一个非常简单的用例。

我有两个字符串:

var a = 'localhost:3000',
    b = '/whatever/; // this can also be whatever/ or /whatever

我需要解析

url.parse(a, b); // so that it takes care of dealing with slashes

但是我明白了

localhost:/whatever/ instead of localhost:3000/whatever/

有什么建议吗？

谢谢!

如果比较以下两个调用，您会发现在字符串前面添加协议(protocol)会产生很大的不同:

> url.parse('http://localhost:3000', '/whatever/')
{ protocol: 'http:',
  slashes: true,
  auth: null,
  host: 'localhost:3000',
  port: '3000',
  hostname: 'localhost',
  hash: null,
  search: '',
  query: {},
  pathname: '/',
  path: '/',
  href: 'http://localhost:3000/' }
>

没有

> url.parse('localhost:3000', '/whatever/')
{ protocol: 'localhost:',
  slashes: null,
  auth: null,
  host: '3000',
  port: null,
  hostname: '3000',
  hash: null,
  search: '',
  query: {},
  pathname: null,
  path: null,
  href: 'localhost:3000' }

您可能正在寻找的是添加协议(protocol)，然后使用 + 而不是 ，:

> url.parse('http://localhost:3000' + '/whatever/')
{ protocol: 'http:',
  slashes: true,
  auth: null,
  host: 'localhost:3000',
  port: '3000',
  hostname: 'localhost',
  hash: null,
  search: null,
  query: null,
  pathname: '/whatever/',
  path: '/whatever/',
  href: 'http://localhost:3000/whatever/' }
