介绍

全自动获取ICP号接口PHP代码放到最底端可以自动获取该网站具体的备案号，优点是全自动获取ICP号，无须手动修改，缺点当然也有了，缺点就是会影响网站的加载速度，给用户带来不好的体验，这就是它的缺点了，我觉的可以学习参考下这个代码。

如果你感觉麻烦的话，可以直接用成品引用

教程

首先先创建个ICP查询接口，代码如下：

<?php
header("Access-Control-Allow-Origin:*");
header("Access-Control-Allow-Methods:GET");
header("Access-Control-Allow-Headers:x-requested-with,content-type");
header("Content-Type:text/html,application/json; charset=utf-8");
if ($_GET['domain']) {
    $domain = getTopHost($_GET['domain']);
} else {
    exit("缺少参数");
}
$timeStamp = time();
$authKey = md5("testtest" . $timeStamp);
$token = json_decode(curl_post("auth", "authKey=$authKey&timeStamp=$timeStamp", "application/x-www-form-urlencoded;charset=UTF-8", "0"));
$token = $token->params->bussiness;
$query = json_decode(curl_post("icpAbbreviateInfo/queryByCondition", '{"pageNum":"","pageSize":"","unitName":"' . $domain . '"}', "application/json;charset=UTF-8", $token));
$query = json_encode($query->params->list);
$query = str_replace("[", "", $query);
$query = json_decode(str_replace("]", "", $query));
$icp = $query->serviceLicence;
$unitName = $query->unitName;
$natureName = $query->natureName;
if (!$token) {
    $icp = "服务器请求频率过高，请稍后再试";
    $msg = "查询失败";
    $code = "0";
} elseif (!$icp) {
    $icp = "未北岸";
    $msg = "查询成功";
    $code = "1";
} else {
    $msg = "查询成功";
    $code = "1";
}
$json = array(
    'icp' => $icp,
    'unitName' => $unitName,
    'natureName' => $natureName,
    'msg' => $msg,
    'result' => $code
);
print_r(json_encode($json, JSON_UNESCAPED_UNICODE));

function curl_post($url, $data, $Content, $token) {
    $ip = "101.".mt_rand(1,255).".".mt_rand(1,255).".".mt_rand(1,255);
    $ch = curl_init();
    $headers = array(
        "Content-Type: $Content",
        "Origin: https://beian.miit.gov.cn/",
        "Referer: https://beian.miit.gov.cn/",
        "token: $token",
        "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.87 Safari/537.36",
        "CLIENT-IP: $ip",
        "X-FORWARDED-FOR: $ip"
    );
    curl_setopt($ch, CURLOPT_URL, "https://hlwicpfwc.miit.gov.cn/icpproject_query/api/" . $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    $content = curl_exec($ch);
    curl_close($ch);
    return $content;
}
function getTopHost($url) {
    if (stristr($url, "http") === false) {
        $url = "http://" . $url;
    }
    $url = strtolower($url);
    $hosts = parse_url($url);
    $host = $hosts['host'];
    $data = explode('.', $host);
    $n = count($data);
    $preg = '/[\w].+\.(com|net|org|gov|edu)\.cn$/';
    $pregip = '/((2(5[0-5]|[0-4]\d))|[0-1]?\d{1,2})(\.((2(5[0-5]|[0-4]\d))|[0-1]?\d{1,2})){3}/';
    if (($n > 2) && preg_match($preg, $host)) {
        $host = $data[$n - 3] . '.' . $data[$n - 2] . '.' . $data[$n - 1];
    } elseif (preg_match($pregip, $host)) {
        $host = $host;
    } else {
        $host = $data[$n - 2] . '.' . $data[$n - 1];
    }
    return $host;
}

接下来创建自动获取ICP北岸号接口代码，代码如下：

<?php
header("Content-type: application/json; charset=utf-8");

// echo ok(get_Domain());
echo "{document.write('" . ok(get_Domain()) ."');}";
function ok($url){
    $url = '这里文字替换成icp北岸查询接口地址?domain=' . $url;
    $data = curl_get($url);
    $data = json_decode($data, true);
    $info = $data['icp'];
    return $info ;
}

function get_Domain()
{
    $scriptpath = str_replace('\\', '/', $_SERVER['SCRIPT_NAME']);
    $sitepath = substr($scriptpath, 0, strrpos($scriptpath, '/'));
    $siteurl = ($_SERVER['SERVER_PORT'] == '443' ) . $_SERVER['HTTP_REFERER'] . $sitepath . '/';
    return $siteurl;
}

function curl_get($url)
{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Linux; U; Android 4.4.1; zh-cn; R815T Build/JOP40D) AppleWebKit/533.1 (KHTML, like Gecko)Version/4.0 MQQBrowser/4.5 Mobile Safari/533.1');
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    $content = curl_exec($ch);
    curl_close($ch);
    return ($content);
}

调用代码示例：

<a href="https://beian.miit.gov.cn" target="_blank"><script src="这里填入接口地址"></script></a>

把调用代码放入你网站备案号填写位置就可以根据当前网站域名自动获取备案号并显示，方便了域名比较多又懒得一个个查询的站长。
