一、为什么要用oss将网站的静态资源存储在oss上,静态资源包括网站图片,html,js,css文件,通过cdn将静态资源分布式缓存在各个节点上实现就就近访问,提高用户访问的响应速度.二、oss怎么用1.在阿里云产品与服务找到-对象存储oss

2.创建Bucket设置该读写权限(ACL)为公共读

3.在AccessKey 管理创建AccessKey

三、创建上传控制器class AliossController extends FwadminController { private $oss_host = 'https://youboxunguanwang.oss-cn-shenzhen.aliyuncs.com';//'https://yifajian2020.oss-cn-beijing.aliyuncs.com';//阿里云oss 外网地址endpoint private $oss_key_id = '';//阿里云oss Access Key ID private $oss_key_secret = '';//阿里云oss Access Key Secret private $oss_bucket_name = '';//创建的bucket名称 private $oss_endpoint = 'oss-cn-shenzhen.aliyuncs.com';//阿里云OSS外网地址 /* * 获得签名 * @param string $path 保存路径 * @return json */ public function get_sign($path = '') { $now = time(); $expire = 300000; //设置该policy超时时间是30s. 即这个policy过了这个有效时间，将不能访问 $end = $now + $expire; $expiration = $this->gmt_iso8601($end); //最大文件大小.用户可以自己设置 $condition = array(0=>'content-length-range', 1=>0, 2=>10485760000); $conditions[] = $condition; //表示用户上传的数据,必须是以$dir开始, 不然上传会失败,这一步不是必须项,只是为了安全起见,防止用户通过policy上传到别人的目录 $start = array(0=>'starts-with', 1=>$this->oss_key_secret, 2=>$path); $conditions[] = $start; $arr = array('expiration'=>$expiration,'conditions'=>$conditions); //echo json_encode($arr); //return; $policy = json_encode($arr); $base64_policy = base64_encode($policy); $string_to_sign = $base64_policy; $signature = base64_encode(hash_hmac('sha1', $string_to_sign, $this->oss_key_secret, true)); $response = array(); $response['accessid'] = $this->oss_key_id; $response['host'] = $this->oss_host; $response['policy'] = $base64_policy; $response['signature'] = $signature; $response['expire'] = $end; //这个参数是设置用户上传指定的前缀 $response['dir'] = $path; echo json_encode($response); return ; } function gmt_iso8601($time) { $dtStr = date("c", $time); $mydatetime = new \DateTime($dtStr); $expiration = $mydatetime->format(\DateTime::ISO8601);
