How to call Sina API to generate short link through php

Sina provides an API for converting long links into short links, which can convert long links into short links in the format t.cn/xxx.

API：
http://api.t.sina.com.cn/short_url/shorten.json (return result is in JSON format)
http://api.t.sina.com.cn/short_url/shorten.xml (return result is in XML format)

Request parameters:
source The AppKey assigned when applying for an application represents the unique identity of the application when calling the interface.
url_long The long links that need to be converted need to be URLencoded, with a maximum of 20.

Multiple url parameters need to be requested using the following method: url_long=aaa&url_long=bbb

Create source method
1. Enter http://open.weibo.com/ and select the menu Micro Connection->Website Access.
2. Click to access now, create a new application, fill in the application name casually, and click Create.
3. After successful creation, AppKey is the value of the source parameter, which can be used to request the creation of a short link.
Test code:

<?php$api = &#39;http://api.t.sina.com.cn/short_url/shorten.json&#39;; // json// $api = &#39;http://api.t.sina.com.cn/short_url/shorten.xml&#39;; // xml$source = &#39;您申请的AppKey&#39;;$url_long = &#39;http://blog.csdn.net/fdipzone&#39;;$request_url = sprintf($api.&#39;?source=%s&url_long=%s&#39;, $source, $url_long);$data = file_get_contents($request_url);echo $data;?>

Return to JSON format

[
    {
        "url_short": "http:\/\/t.cn\/RyVmU5i",
        "url_long": "http:\/\/blog.csdn.net\/fdipzone",
        "type": 0
    }
]

Return to XML format

<?xml version="1.0" encoding="UTF-8"?><urls>
    <url>
        <url_short>http://t.cn/RyVmU5i</url_short>
        <url_long>http://blog.csdn.net/fdipzone</url_long>
        <type>0</type>
    </url></urls>

The generated short link is http://t.cn/RyVmU5i, access will jump to http://blog.csdn.net/fdipzone
The complete calling method is as follows:

<?php/**
 * 调用新浪接口将长链接转为短链接
 * @param  string        $source    申请应用的AppKey
 * @param  array|string  $url_long  长链接，支持多个转换（需要先执行urlencode)
 * @return array
 */function getSinaShortUrl($source, $url_long){

    // 参数检查
    if(empty($source) || !$url_long){        return false;
    }    // 参数处理，字符串转为数组
    if(!is_array($url_long)){        $url_long = array($url_long);
    }    // 拼接url_long参数请求格式
    $url_param = array_map(function($value){
        return &#39;&url_long=&#39;.urlencode($value);
    }, $url_long);    $url_param = implode(&#39;&#39;, $url_param); 

    // 新浪生成短链接接口
    $api = &#39;http://api.t.sina.com.cn/short_url/shorten.json&#39;;    // 请求url
    $request_url = sprintf($api.&#39;?source=%s%s&#39;, $source, $url_param);    $result = array();    // 执行请求
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_URL, $request_url);    $data = curl_exec($ch);    if($error=curl_errno($ch)){        return false;
    }
    curl_close($ch);    $result = json_decode($data, true);    return $result;

}// AppKey$source = &#39;您申请的AppKey&#39;;// 单个链接转换$url_long = &#39;http://blog.csdn.net/fdipzone&#39;;$data = getSinaShortUrl($source, $url_long);

print_r($data);?>
