使用PHP的curl扩展实现跨域post请求,以及file_get_contents()百度短网址例子

<?php

$ch=curl_init();

curl_setopt($ch,CURLOPT_URL,"http://dwz.cn/create.php");

curl_setopt($ch,CURLOPT_POST,true);

curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);

$data=array('url'=>'http://www.cnblogs.com/zuoxiaobing/');

curl_setopt($ch,CURLOPT_POSTFIELDS,$data);

$strRes=curl_exec($ch);

curl_close($ch);

$arrResponse=json_decode($strRes,true);

if($arrResponse['status']==0)

{

/**错误处理*/

echo iconv('UTF-8','GBK',$arrResponse['err_msg'])."\n";

}

/** tinyurl */

echo$arrResponse['tinyurl']."\n";

?>

 

 2.使用file_get_contents();

<?php

$data=array(

    'url'=>'http://www.cnblogs.com/zuoxiaobing/'

);

$data = http_build_query($data);

$opts = array('http' =>

        array(

                'method'  => 'POST',

                'header'  => "Content-type: application/x-www-form-urlencoded\r\n"

                ."Content-Length: " . strlen($data) . "\r\n", 

                    //    "Authorization: Basic ".base64_encode("$https_user:$https_password")."\r\n",

                'content' => $data,

                'timeout' => 60

        )

);

 

$context  = stream_context_create($opts);

$url = 'http://dwz.cn/create.php';

$result = file_get_contents($url, false, $context);

echo $result;
