Question

我在WordPress中的json对象中有一个URL列表。我想用一个前缀将它们分开，我可以看到它们是https://www.example.co，然后得到其余部分，例如/cat1/aa/bb/cc, /?page_id=8830, /xmlrpc.php

var myUrl = [
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc/dd/ee",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat3/aa/bb/cc/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/news/why-residents/attachment/san-francisco-blog/feed/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/xmlrpc.php",
    "Last crawled": "Jun 19, 2019"
  },
  {
    "URL": "https://www.example.co/?page_id=8830",
    "Last crawled": "Jun 18, 2019"
  },
]

我当前的代码如下：

myUrl.forEach(function(item) {
    var urlList = item.URL.split("/");
    //console.log(urlList);
    console.log("https://www.example.co/" + urlList[3]);
});

上面的代码当前无法从前缀中获取其余部分。

任何帮助将不胜感激。谢谢

Answer 1

如果您只想从URL中删除域，则可以使用String.prototype.replace而不是String.prototype.split。

例如：

const myUrl = [
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc/dd/ee",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat3/aa/bb/cc/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/news/why-residents/attachment/san-francisco-blog/feed/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/xmlrpc.php",
    "Last crawled": "Jun 19, 2019"
  },
  {
    "URL": "https://www.example.co/?page_id=8830",
    "Last crawled": "Jun 18, 2019"
  },
];

const paths = myUrl.map(value => value.URL.replace('https://www.example.co', ''));

console.log(paths);

如果数据来自不同的URL域，则可以创建URL对象并获取pathname和search。

const paths = myUrl.map(value => new URL(value.URL).pathname + new URL(value.URL).search);

const myUrl = [
  {
    "URL": "https://www.microsoft.co/cat1/aa/bb/cc",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.google.co/cat2/aa",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc/dd/ee",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat3/aa/bb/cc/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/news/why-residents/attachment/san-francisco-blog/feed/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/xmlrpc.php",
    "Last crawled": "Jun 19, 2019"
  },
  {
    "URL": "https://www.example.co/?page_id=8830",
    "Last crawled": "Jun 18, 2019"
  },
];

const paths = myUrl.map(value => new URL(value.URL).pathname + new URL(value.URL).search);

console.log(paths);

如何正确分割网址，然后在javascript中获取剩余部分？
