PHP之OSS

PHP

首先PHP要引入OSS核心類庫



授權訪問-讀
授權訪問-寫

裡邊包含Config.php,OssClient.php,readAuth.php,writeAuth.php,writeConfig.php等配置檔案
config.php
<?php namespace Utils\OSS;
/**
 *
 * @description 授權訪問-讀
 */
final class Config
{
    const OSS_ACCESS_ID = '****************';
    const OSS_ACCESS_KEY = '**********************';
    //北京節點外網地址：oss-cn-beijing.aliyuncs.com
    //北京節點內網地址：oss-cn-beijing-internal.aliyuncs.com
//    const OSS_ENDPOINT = 'oss-cn-beijing.aliyuncs.com';
//    const OSS_TEST_BUCKET = 'dapeng-video';

    const OSS_ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com';
    const OSS_TEST_BUCKET = 'zhijin-vod';

    const OSS_LIVE_ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com';
    const OSS_LIVE_BUCKET = 'zhijin-live';
}

OssClient.php,readAuth.php，writeAuth.php 裡邊包含一些關於oss的大量資訊，bucket（桶，工具）也就是儲存的工具、以及一些拿到getBucketName（）方法、avatar

上傳頭像到oss
 public function avatar($object = null,$file = null)
    {
        $obj = self::getOssClient();
        $obj->uploadFile(self::bucket,$object,$file);

        return true;
    }

講圖片的許可權設定成public-read
   public function avatarAcl($object = null)
    {
        $obj = self::getOssClient();
        $obj->putObjectAcl(self::bucket,$object,"public-read");

        return true;
    }


writeConfig.php
授權訪問-寫
<?php namespace Utils\OSS;
/**
 * Created by PhpStorm.
 * Date: 16-9-27
 * Time: 下午7:23
 * @description 授權訪問-寫
 */
final class writeConfig
{
    const OSS_ACCESS_ID     = '***********';
    const OSS_ACCESS_KEY    = '**************';
//    const OSS_INTERNAL_HOST = 'http://dapeng-video.vpc100-oss-cn-beijing.aliyuncs.com';
//    const OSS_HOST          = 'http://dapeng-video.oss-cn-beijing.aliyuncs.com';
    const OSS_INTERNAL_HOST = 'http://zhijin-vod.vpc100-oss-cn-hangzhou.aliyuncs.com';
    const OSS_HOST          = 'http://zhijin-vod.oss-cn-hangzhou.aliyuncs.com';

    const OSS_LIVE_INTERNAL_HOST = 'http://zhijin-live.vpc100-oss-cn-hangzhou.aliyuncs.com';
    const OSS_LIVE_HOST          = 'http://zhijin-live.oss-cn-hangzhou.aliyuncs.com';

    const OSS_ENDPOINT = 'oss-cn-hangzhou.aliyuncs.com';
    const OSS_BUCKET = 'zhijin-vod';
