分享调用百度统计api

先进入百度统计，数据管理-数据api页面开通。

可以参考Tongji API用户手册 · Tongji API用户手册 (baidu.com)

第一步：

通过如下URL进入百度账号登录页，此处的登录账号就是您登录百度统计查看报告数据的账号，登录完成后将跳转至获取code的页面：

http://openapi.baidu.com/oauth/2.0/authorize?response_type=code&client_id={填写您的API Key}&redirect_uri=oob&scope=basic&display=popup

第二步：

用户同意授权后，将跳转至一个获取CODE的页面。复制CODE值后可将其加入以下URL换取ACCESS_TOKEN ：

http://openapi.baidu.com/oauth/2.0/token?grant_type=authorization_code&code={第一步拿到的CODE}&client_id={填写您的API Key}&client_secret={写您的Secret Key}&redirect_uri=oob

浏览器访问返回如下：

{
“expires_in”: 2592000,
“refresh_token”:”2.385d55f8615fdfd9edb7c4b5ebdc3e39.604800.1293440400-2346678-124328″,
“access_token”:”1.a6b7dbd428f731035f771b8d15063f61.86400.1292922000-2346678-124328″,
“session_secret”:”ANXxSNjwQDugf8615OnqeikRMu2bKaXCdlLxn”,
“session_key”:” 248APxvxjCZ0VEC43EYrvxqaK4oZExMB”,
“scope”:”basic”
}

下面成品代码，可以在php页面baidutongji()调用：

function baidutongji() {
	$baidutj_option = get_option('baidutj');
	// 获取当前时间的 Unix 时间戳
	$current_time = current_time('timestamp');
	// 指定的时间点
	$specified_time = $baidutj_option['refresh_access_time']; // 转换为 Unix 时间戳
	// 计算10天的秒数
	$ten_days_in_seconds = 10 * 24 * 60 * 60;
    if(empty($baidutj_option)){
        $baidutjarray = array(

            'refresh_access_time'	=> $current_time,
			'tongji_refresh_time'	=> $current_time,
        );
        update_option('baidutj', $baidutjarray, '', 'no');
    }
	// 检查指定时间是否超过当前时间的10天 超过10天刷新access_token这样可以永久不失效
	if ($current_time - $specified_time > $ten_days_in_seconds) {

			$new_option_refresh = array_merge($baidutj_option, $baidutj_refresh_token);
    		wp_cache_delete($new_option_refresh, 'baidutj');
			update_option('baidutj', $new_option_refresh);
		}
	}
	//每小时 调用百度统计并更新数据库数据

从上述步骤得到的数据中包含ACCESS_TOKEN和REFRESH_TOKEN两个值，其中ACCESS_TOKEN的有效期为一个月，REFRESH_TOKEN的有效期为十年。REFRESH_TOKEN的作用就是刷新获取新的ACCESS_TOKEN和REFRESH_TOKEN，如此反复操作来实现ACCESS_TOKEN有效期永久的机制。如果出现突发情况，比如：服务器失联好多天，可以重新第一步第二步获取ACCESS_TOKEN。
