我想拿一根绳子
var a = "http://example.com/aa/bb/"
然后把它加工成一个物体
a.hostname == "example.com"
and
a.pathname == "/aa/bb"
当前回答
只需使用url.js库(用于web和node.js)。
https://github.com/websanova/js-url
url: http://example.com?param=test#param=again
url('?param'); // test
url('#param'); // again
url('protocol'); // http
url('port'); // 80
url('domain'); // example.com
url('tld'); // com
etc...
其他回答
为什么不用呢?
$scope.get_location=function(url_str){
var parser = document.createElement('a');
parser.href =url_str;//"http://example.com:3000/pathname/?search=test#hash";
var info={
protocol:parser.protocol,
hostname:parser.hostname, // => "example.com"
port:parser.port, // => "3000"
pathname:parser.pathname, // => "/pathname/"
search:parser.search, // => "?search=test"
hash:parser.hash, // => "#hash"
host:parser.host, // => "example.com:3000"
}
return info;
}
alert( JSON.stringify( $scope.get_location("http://localhost:257/index.php/deploy/?asd=asd#asd"),null,4 ) );
js-uri(在谷歌Code上可用)接受字符串URL并从中解析URI对象:
var some_uri = new URI("http://www.example.com/foo/bar");
alert(some_uri.authority); // www.example.com
alert(some_uri); // http://www.example.com/foo/bar
var blah = new URI("blah");
var blah_full = blah.resolve(some_uri);
alert(blah_full); // http://www.example.com/foo/blah
var getLocation = function(href) {
var l = document.createElement("a");
l.href = href;
return l;
};
var l = getLocation("http://example.com/path");
console.debug(l.hostname)
>> "example.com"
console.debug(l.pathname)
>> "/path"
使用模块模式的简单而健壮的解决方案。这包括修复IE的路径名不总是有前导正斜杠(/)。
我已经创建了一个Gist和一个JSFiddle，它提供了一个更动态的解析器。我建议你检查一下并提供反馈。
var URLParser = (function (document) {
var PROPS = 'protocol hostname host pathname port search hash href'.split(' ');
var self = function (url) {
this.aEl = document.createElement('a');
this.parse(url);
};
self.prototype.parse = function (url) {
this.aEl.href = url;
if (this.aEl.host == "") {
this.aEl.href = this.aEl.href;
}
PROPS.forEach(function (prop) {
switch (prop) {
case 'hash':
this[prop] = this.aEl[prop].substr(1);
break;
default:
this[prop] = this.aEl[prop];
}
}, this);
if (this.pathname.indexOf('/') !== 0) {
this.pathname = '/' + this.pathname;
}
this.requestUri = this.pathname + this.search;
};
self.prototype.toObj = function () {
var obj = {};
PROPS.forEach(function (prop) {
obj[prop] = this[prop];
}, this);
obj.requestUri = this.requestUri;
return obj;
};
self.prototype.toString = function () {
return this.href;
};
return self;
})(document);
Demo

这不会解析查询和散列，但除此之外它工作得很好。
const getURIParts = (url) => { const matches = url.match(/^(\w+?:\/\/)?([\w-\.]+(?=\/?))?:?(\d*)?([^:]*)/) return { scheme: matches ? matches[1] : undefined, host: matches ? matches[2] : '', port: matches ? matches[3] : undefined, pathname: matches ? matches[4] : '' } } console.log(getURIParts("")) console.log(getURIParts("http://localhost/bla")) console.log(getURIParts("https://api.spotify.com/")) console.log(getURIParts("https://api.spotify.com")) console.log(getURIParts("wss://wss.slack.com/link/?ticket=1234-5678")) console.log(getURIParts("localhost")) console.log(getURIParts("localhost/bla")) console.log(getURIParts("localhost/")) console.log(getURIParts("api.spotify.com/bla/two")) console.log(getURIParts("api.spotify.com:8000/bla/two")) console.log(getURIParts("https://api.spotify.com:8800/")) console.log(getURIParts("/mp3-preview/f504e6b8e037771318656394f532dede4f9bcaea"))
