帝國cms相關搜索功能擴展（利用百度下實現）

類似這樣，根據標題獲取一批相關的詞，然後開啓搜索功能，點擊這個就能跳轉到帝國cms搜索頁面，前提是你帝國cms的搜索功能經過改良，可以模糊搜索！

PHP獲取百度下拉

function getBaiduSuggestion($title) {
    $title = urlencode($title);
    $api = "https://www.baidu.com/sugrec?pre=1&p=1&ie=utf-8&prod=pc&csor=2&wd=".$title."";

    $ch = curl_init();
    curl_setopt_array($ch, [
        CURLOPT_URL => $api,
        CURLOPT_TIMEOUT => 5,
        CURLOPT_RETURNTRANSFER => true,
    ]);

    $r = curl_exec($ch);
    curl_close($ch);

    $r = json_decode($r, true);

    if (!empty($r['g'])) {
        return array_column($r['g'], 'q');
    } else {
        return false;
    }
}

帝國內容模板調用

<h3>相關搜索</h3>
<style>
.searchA{
	padding: 0 10px 6px 0;
	display: block;
}
</style>
<?php 
$otherSearch = getBaiduSuggestion($navinfor['title']);
if($otherSearch){
	foreach($otherSearch as $v){
		echo "<a class='searchA' href='[!--news.url--]moreSearch/".urlencode($v).".html'>$v</a>";
	}
}
?>

僞靜態規則修改

rewrite ^/moreSearch/(.*?)\.html$ /e/search/index.php?searchget=1&keyboard=$1&show=title&tempid=1&dopost=search last;

搜索頁面返回的代碼修改

Header("Location:$public_r[newsurl]e/search/result/?searchid=$searchid".$dogetvar);
