利用PHP通过API清理Cloudflare缓存

每次清理Cloudflare网站缓存的时候，总是要登录Cloudflare，然后去清理缓存，总觉得有点麻烦，想着Cloudflare有开放的API可以利用一下，这里记录一下代码

<?php
        $cust_email = ''; //账户邮箱地址
        $cust_xauth = ''; //Global API Key 通过登录Cloudflare，在我的个人资料，API令牌中查看
        $cust_domain = ''; //要清理缓存的域名，只填主域名即可，不要填二级域名
        $url = "https://api.cloudflare.com/client/v4/zones?name=".$cust_domain."&status=active&page=1&per_page=5&order=status&direction=desc&match=all";
        $header = array(
            'X-Auth-Email: '.$cust_email.'',
            'X-Auth-Key: '.$cust_xauth.'',
            'Content-Type: application/json'
        );
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
	curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
	curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
	curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
	curl_setopt($ch, CURLOPT_HEADER, 0); 
	curl_setopt($ch, CURLOPT_URL, $url);
	$result = curl_exec($ch);
	curl_close($ch);
        $json = json_decode($result,true);
        $cust_zone = $json['result'][0]['id']; 
        $url = "https://api.cloudflare.com/client/v4/zones/".$cust_zone."/purge_cache";
        $header = [
            'X-Auth-Email: '.$cust_email,
            'X-Auth-Key: '.$cust_xauth,
            'Content-Type: application/json'
        ];
	//清空所有缓存
        $post_data = json_encode(array("purge_everything" => true));
	/*清空指定URL
	$files = array(
		'网址1',
		'网址2',
		'以此类推'
	);
	$post_data = json_encode(array('files'=>$files));
	*/
        $ch = curl_init();
	curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
        curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
	curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
        curl_setopt($ch, CURLOPT_TIMEOUT,10);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); 
        $html = curl_exec($ch);
        curl_close($ch);
        $result = json_decode($html,true);
        if($result['success']==1){
		echo "Cloudflare缓存已成功清除";die;
	}
	echo "清除Cloudflare缓存时出错";die;
	
?>
