我需要从给定的URL中提取完整的协议、域和端口。例如:
https://localhost:8181/ContactUs-1.0/contact?lang=it&report_type=consumer
>>>
https://localhost:8181

当前回答
host
var url = window.location.host;
返回localhost: 2679
主机名
var url = window.location.hostname;
返回本地主机
其他回答
为什么不使用:
let full = window.location.origin
host
var url = window.location.host;
返回localhost: 2679
主机名
var url = window.location.hostname;
返回本地主机
Window.location.origin就足以得到相同的。
ES6风格,具有可配置参数。
/**
* Get the current URL from `window` context object.
* Will return the fully qualified URL if neccessary:
* getCurrentBaseURL(true, false) // `http://localhost/` - `https://localhost:3000/`
* getCurrentBaseURL(true, true) // `http://www.example.com` - `https://www.example.com:8080`
* getCurrentBaseURL(false, true) // `www.example.com` - `localhost:3000`
*
* @param {boolean} [includeProtocol=true]
* @param {boolean} [removeTrailingSlash=false]
* @returns {string} The current base URL.
*/
export const getCurrentBaseURL = (includeProtocol = true, removeTrailingSlash = false) => {
if (!window || !window.location || !window.location.hostname || !window.location.protocol) {
console.error(
`The getCurrentBaseURL function must be called from a context in which window object exists. Yet, window is ${window}`,
[window, window.location, window.location.hostname, window.location.protocol],
)
throw new TypeError('Whole or part of window is not defined.')
}
const URL = `${includeProtocol ? `${window.location.protocol}//` : ''}${window.location.hostname}${
window.location.port ? `:${window.location.port}` : ''
}${removeTrailingSlash ? '' : '/'}`
// console.log(`The URL is ${URL}`)
return URL
}
console.log(`${req.protocol}://${req.get('host')}/${req.originalUrl}`);
要求的事情。protocol -给出你使用的协议(例如HTTP) get(host) -给出带有端口号的主机名(例如localhost:8080)
