php调用新浪短链接API的方法,php调用新浪api

本文实例讲述了php调用新浪短链接API的方法。分享给大家供大家参考。具体方法如下:

复制代码 代码如下:

//Sina App_Key
define('SINA_APPKEY', '31641035');
function curlQuery($url) {
 //设置附加HTTP头
 $addHead = array(
 "Content-type: application/json"
 );
 //初始化curl,当然,你也可以用fsockopen代替
 $curl_obj = curl_init();
 //设置网址
 curl_setopt($curl_obj, CURLOPT_URL, $url);
 //附加Head内容
 curl_setopt($curl_obj, CURLOPT_HTTPHEADER, $addHead);
 //是否输出返回头信息
 curl_setopt($curl_obj, CURLOPT_HEADER, 0);
 //将curl_exec的结果返回
 curl_setopt($curl_obj, CURLOPT_RETURNTRANSFER, 1);
 //设置超时时间
 curl_setopt($curl_obj, CURLOPT_TIMEOUT, 15);
 //执行
 $result = curl_exec($curl_obj);
 //关闭curl回话
 curl_close($curl_obj);
 return $result;
}
//简单处理下url,sina对于没有协议(http://)开头的和不规范的地址会返回错误
function filterUrl($url = '') {
 $url = trim(strtolower($url));
 $url = trim(preg_replace('/^http:///', '', $url));
 if ($url == '')
 return false;
 else
 return urlencode('http://' . $url);
}
//根据长网址获取短网址
function sinaShortenUrl($long_url) {
 //拼接请求地址,此地址你可以在官方的文档中查看到
 $url = 'http://api.t.sina.com.cn/short_url/shorten.json?source=' . SINA_APPKEY . '&url_long=' . $long_url;
 //获取请求结果
 $result = curlQuery($url);
 //下面这行注释用于调试,你可以把注释去掉看看从sina返回的信息是什么东西
 //print_r($result);exit();
 //解析json
 $json = json_decode($result);
 //异常情况返回false
 if (isset($json->error) || !isset($json[0]->url_short) || $json[0]->url_short == '')
 return false;
 else
 return $json[0]->url_short;
}
//根据短网址获取长网址,此函数重用了不少sinaShortenUrl中的代码,以方便你阅读对比,你可以自行合并两个函数
function sinaExpandUrl($short_url) {
 //拼接请求地址,此地址你可以在官方的文档中查看到
 $url = 'http://api.t.sina.com.cn/short_url/expand.json?source=' . SINA_APPKEY . '&url_short=' . $short_url;
 //获取请求结果
 $result = curlQuery($url);
 //下面这行注释用于调试,你可以把注释去掉看看从sina返回的信息是什么东西
 //print_r($result);exit();
 //解析json
 $json = json_decode($result);
 //异常情况返回false
 if (isset($json->error) || !isset($json[0]->url_long) || $json[0]->url_long == '')
 return false;
 else
 return $json[0]->url_long;
}
//要缩短的网址
$url = $long; //这里自己看着办,修改成你要缩短的网址还是获取post的数据还是怎么滴。
$url = filterUrl($url);
$short = sinaShortenUrl($url);
$ulong = sinaExpandUrl($short);
?>


本文中短连接已经附带的一个appkey不用再自己申请KEY当然你如果需要使用你自己的您也可以自己去替换。至于用法就看你了,镶入到其他程序使用,单独做个生成短连接的页面都可以。使用方法就不多说了。

希望本文所述对大家的PHP程序设计有所帮助。
