最近由于业务增长，图片请求量增加，导致某云的云存储费用增加，后来联系了白山对比价格，相对会减少一部分开支，于是就开始着手对接白山云存储业务。

首先查看白山云存储开发文档，完全兼容aws接口文档，考虑到使用maccms

的便捷和统一性，就在原有的后台管理中添加新的存储方式。aws有专门的PHP sdk包，可以通过composer或者下载安装包的方式进行集成，下面介绍下composer方式。

https://docs.aws.amazon.com/zh_cn/sdk-for-php/v3/developer-guide/guide_configuration.html

在项目中执行

composer require aws/aws-sdk-php

然后在maccms后台找到附件配置相关的控制器方法，比葫芦画瓢，对照着原有的三方存储，增加扩展文件和视图文件即可，可以参考下面代码：

<?php
namespace app\common\extend\upload;

use Aws\S3\S3Client;
use Aws\Exception\AwsException;


class Aws
{
    public $name = 'AWS云存储';
    public $ver = '3.0';
    
    public function submit($file_path)
    {
        $bucket = $GLOBALS['config']['upload']['api']['aws']['bucket'];
        $accessKey = $GLOBALS['config']['upload']['api']['aws']['accesskey'];
        $secretKey = $GLOBALS['config']['upload']['api']['aws']['secretkey'];
        $endpoint = $GLOBALS['config']['upload']['api']['aws']['url'];

        $s3 = new S3Client([
            'version' => 'latest',
            'region' => 'us-east-2',
                'credentials' => [
                    'key' => $accessKey,  //请替换为您自己的access_key
                    'secret' => $secretKey, //请替换为您自己的secret_key
                ],
                'endpoint' => $endpoint
        ]);
        
        $imgName = date('Y',time()).'/'.date('m',time()).'/'.mac_get_uniqid_code().'.'.pathinfo($file_path)['extension'];
        
        $filePath = ROOT_PATH . $file_path;
        
        $resp = $s3->putObject([
            'ACL' => 'public-read',
            'Bucket' => $bucket,
            'Key' => $imgName,//文件名
            'ContentType' => 'image/jpeg',  //请替换为合适的文件类型
            //'Body' => 'file content as a string',
            'SourceFile' => $file_path//'/root/test.jpg',
        ]);
        @unlink($filePath);
        return $resp['ObjectURL'];
     
    }
}



//文件路径
application/common/extend/upload/Aws.php

接下来是视图文件
//application/admin/view/extend/upload/aws.html


<div class="layui-form-item upload_mode mode_Aws" {if condition="$config['upload']['mode'] neq 'Aws'"}style="display:none;" {/if}>
<label class="layui-form-label">AWS API：</label>
<div class="layui-input-block">
    <a href="https://aws.amazon.com/cn/documentation/sdk-for-php/" target="_blank" class="layui-btn layui-btn-primary">点击申请 https://aws.amazon.com/cn/documentation/sdk-for-php/</a>
</div>
</div>
<div class="layui-form-item upload_mode mode_Aws" {if condition="$config['upload']['mode'] neq 'Aws'"}style="display:none;" {/if}>
<label class="layui-form-label">服务名：</label>
<div class="layui-input-inline w200">
    <input type="text" name="upload[api][aws][bucket]" placeholder="白山云-Bucket" value="{$config['upload']['api']['aws']['bucket']}" class="layui-input"  >
</div>
<label class="layui-form-label">access_key：</label>
<div class="layui-input-inline w200">
    <input type="text" name="upload[api][aws][accesskey]" placeholder="白山云-access_key" value="{$config['upload']['api']['aws']['accesskey']}" class="layui-input"  >
</div>
<label class="layui-form-label">secretkey：</label>
<div class="layui-input-inline w200">
    <input type="text" name="upload[api][aws][secretkey]" placeholder="白山云-secretkey" value="{$config['upload']['api']['aws']['secretkey']}" class="layui-input"  >
</div>
<label class="layui-form-label">endpoint：</label>
<div class="layui-input-inline w200">
    <input type="text" name="upload[api][aws][url]" placeholder="白山云-endpoint" value="{$config['upload']['api']['aws']['url']}" class="layui-input"  >
</div>
</div>

然后登录maccms管理后台填写相应的配置，测试即可完成。
