发现之前弄的typecho百度收录检测代码不能用了，不管是收录还是未收录都显示已收录，于是便百度了一下，本方法采用的是调用api的方法，效果请看本博客的文章末尾处。
1.在模板post.php显示收录的位置加入以下代码（样式自己弄下）
<span id="baidu_result">加载中</span>2.还是在post.php内加入以下代码（必须引入jquery）
<script>
function baidu_check(){
var url= window.location.href
$.getJSON("https://cn1.api.wfblog.net/baidu.php?domain="+url,function(result){ //调用api
if (result.code == 200) {
$('#baidu_icon').removeClass('glyphicon-refresh');
$('#baidu_icon').addClass('glyphicon-ok-circle');
$('#baidu_result').text('百度已收录');
}else if(result.code == 403){
$('#baidu_icon').removeClass('glyphicon-refresh');
$('#baidu_icon').addClass('glyphicon-info-sign');
/*$('#baidu_result').text('百度未收录');*/
$('#baidu_result').html('<a style="color:red;" rel="external nofollow" title="点击提交收录！" target="_blank" href="https://ziyuan.baidu.com/linksubmit/url?sitename='+url+'">百度未收录</a>');
}else{
$('#baidu_icon').removeClass('glyphicon-refresh');
$('#baidu_icon').addClass('glyphicon-remove-circle');
$('#baidu_result').text('查询收录失败');
}
});
}
baidu_check();
</script>为了防止API挂掉，也可以自己搭建API，API代码如下：
<?php
/**
* Baidu
* @editer: Weifeng
* @link: https://wfblog.net
* @version: 1.0
*/
error_reporting(0);
header("Access-Control-Allow-Origin:*");
header('Content-type: application/json');
$domain = @$_GET['domain'];
if(!isset($domain) || empty($domain) || $domain==''){
$data = array(
"code" => false,
"msg" => "未传入请求参数！"
);
echo json_encode($data,JSON_UNESCAPED_UNICODE);
exit;
}
if(substr($domain, -1) == '/'){
$domain = substr($domain,0,strlen($domain)-1);
}
$data = checkBaidu($domain);
echo json_encode($data,JSON_UNESCAPED_UNICODE);
function checkBaidu($url){
$header = array(
"Host:www.baidu.com",
"Content-Type:application/x-www-form-urlencoded",//post请求
"Connection: keep-alive",
"Referer:https://www.baidu.com",
"User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.162 Safari/537.36"
);
$url = 'https://www.baidu.com/s?ie=UTF-8&wd='.urlencode($url).'&usm=3&rsv_idx=2&rsv_page=1';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_HTTPHEADER, $header);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
if(strpos($output, '没有找到') || strpos($output, '很抱歉')){
$data = array(
"code" => 403,
"msg" => "该域名暂时未被百度收录！"
);
}else{
$number = GetBetween($output,'<span class="nums_text">百度为您找到相关结果约','个</span>');
if(empty($number) || $number == 0){
$number = GetBetween($output,'<b>找到相关结果数约','个</b></p>');
if(empty($number) || $number == 0){
$data = array(
"code" => false,
"msg" => "获取百度收录失败！"
);
return $data;
}
}
$data = array(
"code" => 200,
"msg" => "该域名已被百度收录！",
"number" => str_replace(',','',$number)
);
}
return $data;
}
function GetBetween($content,$start,$end){
$r = explode($start, $content);
if (isset($r[1])){
$r = explode($end, $r[1]);
return $r[0];
}
}
