aws s3 sdk c++使用指南、适配阿里云oss和aws

本文介绍了使用AWS和阿里云OSS的SDK实现PutObject操作的流程。AWS版本需要初始化API，配置凭证和端点信息，创建S3客户端后设置请求参数（Bucket、Key和文件流），最后执行上传并处理结果。阿里云OSS版本类似，但需要额外配置EndpointProvider和路径样式。两个版本都包含错误处理逻辑，上传成功会返回ETag。使用前需提前申请存储桶(Bucket)等必要信息。代码示例

通过介绍PutObject这个使用流程来介绍使用：大家好好看即可
1、sdk for aws的用法如下：

	Aws::SDKOptions options;

	Aws::InitAPI(options);

	{
		const Aws::Auth::AWSCredentials credential("dadsadas111", "sadadsaddasdas");
		Aws::Client::ClientConfiguration clientConfig;
		clientConfig.endpointOverride = "https://s3.ap-southeast-2.amazonaws.com"; // da江区 endpoint
		clientConfig.region = "ap-southeast-2";                                  // dsadas区 region id

		Aws::S3::S3Client s3Client(credential, nullptr, clientConfig);

		Aws::S3::Model::PutObjectRequest putObjectRequest;
		putObjectRequest.SetBucket("asddas");
		putObjectRequest.SetKey("asdas.log");

		std::shared_ptr<Aws::IOStream> requestBody = Aws::MakeShared<Aws::FStream>("PutObjectAllocationTag", "D:/dasdas.log", std::ios_base::in | std::ios_base::binary);
		if (!*requestBody)
		{
			Aws::ShutdownAPI(options);
		}
		putObjectRequest.SetBody(requestBody);
		Aws::S3::Model::PutObjectOutcome putObjectOutcome = s3Client.PutObject(putObjectRequest);
		if (!putObjectOutcome.IsSuccess())
		{
			std::cerr << "Error: PutObject: " << putObjectOutcome.GetError().GetMessage() << std::endl; // 上传错误，输出错误信息
		}
		else
		{
			std::cout << "ETag: " << putObjectOutcome.GetResult().GetETag() << std::endl; // 上传成功，打印 ETag
		}
	}
	Aws::ShutdownAPI(options);

2、sdk for alioss的用法如下：

Aws::SDKOptions options;

	Aws::InitAPI(options);

	{
		const Aws::Auth::AWSCredentials credential("LTAI5sdasdaq", "Fxg7H2XFasdasH21dsasdA0H");
		Aws::Client::ClientConfiguration clientConfig;
		clientConfig.endpointOverride = "https://oss-cn-beijing.aliyuncs.com"; // 华东-浙江区 endpoint
		clientConfig.region = "oss-cn-beijing";                                  // 华东-浙江区 region id
		auto provider = Aws::MakeShared<Aws::S3::S3EndpointProvider>(Aws::S3::S3Client::GetAllocationTag());
		provider->AccessClientContextParameters().SetForcePathStyle(false);
		// Aws::S3::S3Client s3Client(credential, provider,clientConfig);
		Aws::S3::S3Client s3Client(credential,provider ,clientConfig);
		
		Aws::S3::Model::PutObjectRequest putObjectRequest;
		putObjectRequest.SetBucket("buadsdasbu12");
		putObjectRequest.SetKey("badsdsa1253.log");
		std::shared_ptr<Aws::IOStream> requestBody = Aws::MakeShared<Aws::FStream>("PutObjectAllocationTag", "D:/tessdadast.log", std::ios_base::in | std::ios_base::binary);
		if (!*requestBody)
		{
			Aws::ShutdownAPI(options);
			return;
		}
		putObjectRequest.SetBody(requestBody);
		Aws::S3::Model::PutObjectOutcome putObjectOutcome = s3Client.PutObject(putObjectRequest);
		if (!putObjectOutcome.IsSuccess())
		{
			std::cerr << "Error: PutObject: " << putObjectOutcome.GetError().GetMessage() << std::endl; // 上传错误，输出错误信息
		}
		else
		{
			std::cout << "ETag: " << putObjectOutcome.GetResult().GetETag() << std::endl; // 上传成功，打印 ETag
		}
	}
	Aws::ShutdownAPI(options);

前提：需要申请桶信息等
