PHP通过调用新浪API生成t.cn格式短网址链接的方法详解

<?php
$api = 'http://api.t.sina.com.cn/short_url/shorten.json'; // json
// $api = 'http://api.t.sina.com.cn/short_url/shorten.xml'; // xml
$source = '您申请的AppKey';
$url_long = 'https://www.jb51.net/';
$request_url = sprintf($api.'?source=%s&url_long=%s', $source, $url_long);
$data = file_get_contents($request_url);
echo $data;
?>

[
  {
    "url_short": "http:\/\/t.cn\/Rki0twp",
    "url_long": "http:\/\/www.cnblogs.com\/daxiangxm",
    "type": 0
  }
]

<?xml version="1.0" encoding="UTF-8"?><urls>

    <url_long>https://www.jb51.net/</url_long>
