[tip_success]自己抽空写了给代码，适合ripro-v2【ripro转v2】,有点代码基础的可以举一反三，其他主题页适用！ 支持，百度，蓝奏，123网盘，微云，189网盘，坚果等，原则上网盘都支持。可参考本网站[/tip_success]

第一步添加下面到function.php文件

[rihide]

//链接状态
function pan_check_link($url)
{   
    $link = $url;
	if ($link == "链接为空") {
		return array("status" => "1", "msg" => "存在空链接");
	}
	$response = wp_remote_get($link);//WordPress远程获取内容
	if (is_array($response) && !is_wp_error($response) && $response["response"]["code"] == "200") {
		$header = $response["headers"];
		$body = $response["body"];
		if (strpos($body, "页面不存在") !== false) {
			return array("status" => "1", "msg" => "页面不存在,请联系客服处理!");
		}
		if (strpos($body, "链接不存在") !== false) {
			return array("status" => "1", "msg" => "链接不存在,请联系客服处理!");
		}
		return array("status" => "1", "msg" => "链接正常请放心购买/下载");
	}
	return array("status" => "0", "msg" => "链接失效，请联系客服处理！");
}
function check_url_state()
{
	$post_id = !empty($_POST['post_id']) ? (int) $_POST['post_id'] : 0;
	if(get_post_meta($post_id, "cao_downurl", true) ){
        $c_link=get_post_meta($post_id, "cao_downurl", true);
    }else{
    	$arr=get_post_meta($post_id, "cao_downurl_new", true)?get_post_meta($post_id, "cao_downurl_new", true):"";
    	foreach ($arr as $key => $item) {
    	    $c_link=$item['url'];
    	}
    }
	$state = pan_check_link($c_link);
	echo json_encode($state);exit;
}

[/rihide]

第二步：添加JS文件

[rihide]

function zp_check_pan_url(e) {
    'use strict';
    $('.zptheme-check-url').on('click', function () {
            var t = $(this);
            t.html();
            rizhuti_v2_ajax(
                { 
                    action: 'check_url_state', 
                    post_id: t.data("id")
                },
                function (e) {
                    t.html(iconspin+'正在检测中');
                },
                function (e) {
                    1 == e.status
                        ? (t.toggleClass("ok"), t.attr("disabled", "true").html(e.msg))
                        : t.attr("disabled", "true").html(e.msg);
                }
            );
        })
}
jQuery(function () {
    zp_check_pan_url()
})

[/rihide]

第三步：添加检测按钮

在文件shop-widget.php //按钮组件 异步模式前添加以下代码
[rihide]

echo'<button type="button" class="btn btn-block btn-info mb-2 zptheme-check-url" data-id="'.$post_id.'">检测链接状态</button>';

[/rihide]
