主动的向搜索引擎提交站点地图是站长必要的SEO手段，有利于搜索引擎的抓取，从而使更多的站点收录成为可能。前不久发现Bing也可以通过api提交，于是找到了可以推送的php代码，然后通过服务器宝塔的预定任务每隔几天自动推送一次。

实现步骤
进入必应网站管理员工具Webmaster Tools，api访问，找到并复制

需要的php推送代码
修改推送代码中的域名信息、sitemap.xml地址信息、必应提交key

<?php
$arr = array(
    'https://www.4241.cn' => array(
        'url'  => array(
            "https://www.4241.cn/sitemap.xml"
            ),
        'bing_key' => "必应搜索引擎提交中心复制的api"
    ),
);

foreach ($arr as $i => $j) {
    //网站地址
    $website = $i;
    //站点地图
    $url = $j['url'];
    //必应key
    $bing_key = $j['bing_key'];

    //配额接口调用地址
    $quota_api = "https://ssl.bing.com/webmaster/api.svc/json/GetUrlSubmissionQuota?siteUrl=$website&apikey=$bing_key";

    //URL提交API接口调用地址
    $seturl_api = "https://ssl.bing.com/webmaster/api.svc/json/SubmitUrlBatch?apikey=$bing_key";

    $s = file_get_contents($quota_api);
    $s = json_decode($s, true);

    echo "$website 必应今日剩余配额：".$s['d']['DailyQuota']."  本月剩余配额：".$s['d']['MonthlyQuota'];echo '<br>';

    if($s['d']['DailyQuota']){
        $ch = curl_init();

        //防https错误
        $xmlresponse = curl_exec($ch);
        $xml=simplexml_load_string($xmlresponse);

        $urls = array();
        foreach ($url as $key => $value) {
            curl_setopt($ch, CURLOPT_URL, $value);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
            $xmlresponse = curl_exec($ch);
            $xml=simplexml_load_string($xmlresponse);

            foreach ($xml as $key => $value) {
                $urls[] = $value->loc;
            }

        }
        shuffle($urls);
        //必应api提交每次上限100条
        if ($s['d']['DailyQuota']>=100) {
            $max = 100;
        } else {
            $max = $s['d']['DailyQuota'];
        }
        $urls = array_slice($urls, 0,$s['d']['DailyQuota']);
        if(!$urls){
            echo $website.' 今日配额已全部提交！';continue;
        }
        $url_data = array_chunk($urls, $max, true);

        foreach ($url_data as $key => $value) {
            $url_str = implode(',',$value);
            $url_arr = explode(',',$url_str);
            $data = array(
                "siteUrl"=>$website,
                "urlList"=>$url_arr
                );
            $ch = curl_init();
            $options =  array(
                CURLOPT_URL => $seturl_api,
                CURLOPT_POST => true,
                CURLOPT_RETURNTRANSFER => true,
                CURLOPT_POSTFIELDS => json_encode($data),
                CURLOPT_HTTPHEADER => array('Content-Type: application/json'),
            );
            curl_setopt_array($ch, $options);
            $result = curl_exec($ch);
            echo "$website 必应提交信息：".$result;echo '<br>';
        }
    }
//阿影资源网 www.4241.cn
}
?>

最后设置宝塔或者监控，在宝塔中设置定时任务，任务类型是访问URL，例如：域名/bing.php；必应默认最多提交100个url/天。如果需要更多的份额，需要额外申请。
