前言

最近项目需要用到对象存储，将所有上传文件，存储到BOS云存储上。在开发过程中，遇到一些小小的问题，做个简单记录。

功能实现

1 下载sdk（以下两种方式，任选其一即可）

（1）使用composer 安装

composer require aws/aws-sdk-php

（2）下载aws.phar

2 项目中使用，代码实现。

<?php
    // sdk
    $bucket = 'upload'; // 容器名称[调整填写自己的容器名称]
    $key = 'index.html'; // 要上传的文件
    $region = 'us-east-1';//地区
    $endpoint = 'https://obs-hazz.cucloud.cn';//
    $ak = 'XXXXXXXXXXXXXXXXXXXXXXXXXX';// ak
    $sk = 'XXXXXXXXXXXXXXXXXXXXXXXXXX';// sk

    // https://github.com/aws/aws-sdk-php
    include 'aws.phar';

    // Register S3 Client
    $s3 = new Aws\S3\S3Client([
        'version' => 'latest',
        's3ForcePathStyle' => true,
        'region' => $region,
        'endpoint' => $endpoint,
        'credentials' => [
            'key' => $ak,
            'secret' => $sk,
        ],
        // 'scheme' => 'http',
        // 'debug' => true,
    ]);


    // Put data to S3 bucket
    try
    {
        $key = '5.jpg';
        $s3->putObject([
            'Bucket' => $bucket,
            'Key'    => $key,
            'Body'   => fopen($key,"r"),
        ]);
    }
    catch (Aws\S3\Exception\S3Exception $e) {
        exit('Error: ' . $e->getAwsErrorMessage() . PHP_EOL);
    }


    // GET Object
    try
    {
        $result = $s3->getObject([
            'Bucket' => $bucket,
            'Key'    => $key
        ]);
        echo "\n---BEGIN---\n";
        echo $result['Body'];
        echo "\n----END----\n\n";
    }
    catch (Aws\S3\Exception\S3Exception $e) {
        exit('Error: ' . $e->getAwsErrorMessage() . PHP_EOL);
    }


    // GET Object head
    try
    {
        $result = $s3->headObject([
            'Bucket' => $bucket,
            'Key'    => $key,
        ]);
        echo "\n---BEGIN---\n";
        echo $result->get("LastModified");
        echo $result->get("ContentLength");
        echo $result->get("AcceptRanges");
        echo "\n----END----\n\n";
    }
    catch (Aws\S3\Exception\S3Exception $e) {
        exit('Error: ' . $e->getAwsErrorMessage() . PHP_EOL);
    }


    // Delete object
    try
    {
        echo 'Attempting to delete ' . $key . '...' . PHP_EOL;

        $result = $s3->deleteObject([
            'Bucket' => $bucket,
            'Key'    => $key
        ]);
    }
    catch (Aws\S3\Exception\S3Exception $e) {
        exit('Error: ' . $e->getAwsErrorMessage() . PHP_EOL);
    }

注意：

（1）以下是我程序中功能实现部分，项目中我只用到了文件上传与文件删除，各位工友使用的话要调整自己的配置哟~

（2）本地图片上传与抓取远程图片上传是不一样的哟~

（3）上传文件时要注意设置'ACL' => 'public-read'；
