php对接AWS S3云存储，上传S3及访问权限问题

首先先下载sdk包
https://docs.aws.amazon.com/zh_cn/sdk-for-php/v3/developer-guide/getting-started_installation.html

S3创建存储桶

去安全凭证-》创建访问秘钥

创建的时候会提示，主账号创建不安全，这个时候我们需要创建一个IAM账号来创建秘钥
创建的步骤访问这个链接 https://www.codenong.com/a513c91eac7186db59fe/

创建之后来到代码这一块

//$keyName是存储S3的路径
//$filepath是本地图片的路径
awsUploadFile($keyName, $filepath);
//删除本地文件
unlink('.' . $resultData['url']);function awsUploadFile($keyName, $filepath)
{//引入文件require_once '../extend/aws/aws-autoloader.php';//    set_time_limit(0);$awsConfig = ['version' => 'latest',//版本'acl' => 'public-read',//权限//这个一定要加，是访问权限'bucket' => config('site.S3bucket'),//存储桶名称'region' => 'ap-southeast-1',//区域 和 亚马逊资源服务器创建的桶块区域一致'key_id' => config('site.S3key_id'),//Access key ID'access_key' => config('site.S3access_key'),//Secret access key];//实例化$credentials = new Aws\Credentials\Credentials($awsConfig['key_id'],$awsConfig['access_key']);$s3 = new Aws\S3\S3Client(['version' => $awsConfig['version'],//版本'region' => $awsConfig['region'],//区域'credentials' => $credentials,]);if(!file_exists($filepath)){dump('file does not exist');exit;}
//    $http = new GuzzleHttp\Client();
//    $res = $http->request('GET', $filepath);try {$result = $s3->putObject(['Bucket' => $awsConfig['bucket'],'Key' => $keyName,'Body' => fopen($filepath, 'r'),'ACL' => 'public-read',//这个一定要加，是访问权限
//            'Body' => $res->getBody(),
//            'ContentLength' => $res->getHeader('content-length')[0],]);} catch (Exception $exception) {echo "Failed to upload $filepath with error: " . $exception->getMessage();exit("Please fix error with file upload before continuing.");}return $result;
}

如果是手动上传的文件需要开一下权限
