批量入库

因为maccms自带的采集采集起来很慢，而且很多资源站的采集接口不能对内容排序，导致最旧的数据最后入库。用java写个采集程序，采集完入库的时候发现不能一次性入库多个数据，导致入库也很慢，所以就在入库控制器写了个方法批量入库。

Receive.php

public function foo()
{
	$info = $this->_param;
	if (!array_key_exists("vods", $info) || empty($info["vods"]))
	{
	    echo json_encode(['code'=>2002,'msg'=>"vods is required"],JSON_UNESCAPED_UNICODE);
            exit;
	}
        $vods = json_decode($info["vods"], true);
        
        if (null == $vods)
        {
            echo json_encode(['code'=>2002,'msg'=>"the format of vods is incorrect"],JSON_UNESCAPED_UNICODE);
            exit;
        }
        
        $inter = mac_interface_type();
        $res = [];
    	foreach ($vods as $vod)
    	{
    		if(empty($vod['type_id'])) {
            	$vod['type_id'] = $inter['vodtype'][$vod['type_name']];
        }
        	
        $data['data'][] = $vod;

    echo json_encode($res,JSON_UNESCAPED_UNICODE);
}

资源打包

有时候需要给其他程序全量下载视频数据，有个接口会很方便

Provide.php

// format: json返回json格式数据;无或line或其他返回的数据，是一行一条数据，且每一行都是合法的json格式
public function bar()
