以下使用C++将内存数据写入到S3 bucket中的Sample code, 包含鉴权认证过程

//aws sdk 相关头文件 
#include "aws/core/auth/AWSCredentialsProvider.h"
#include "aws/core/client/RetryStrategy.h"
#include "aws/transfer/TransferManager.h"
#include "aws/core/Aws.h"
#include "aws/s3/S3Client.h"

int main()
{
	Aws::SDKOptions options;
	Aws::InitAPI(options);
	string regionName = "xxx";
	string accessKey = "*******";
	string secret = "********";
	string token = "**********************";
	string bucketName = "xxx";
	string objName = "s3upload/test.txt";
	string content = "s3 upload test";
	Aws::Client::ClientConfiguration clientConfig;
	clientConfig.scheme = Aws::Http::Scheme::HTTPS;
	clientConfig.connectTimeoutMs = 4 * 1000;
	clientConfig.requestTimeoutMs = 4 * 1000;
	clientConfig.region = regionName.c_str();
	clientConfig.verifySSL = true;
	Aws::Auth::AWSCredentials credentials(accessKey.c_str(), secret.c_str(), token.c_str());
	auto s3Client = new Aws::sS3::S3Client(credentials, clientConfig);
	const Aws::String bucket = bucketName.c_str();
	const Aws::String objectName = objName.c_str();
	Aws::S3::Model::PutObjectRequest request;
	request.SetBucket(bucket);
	request.SetKey(objectName);
	const std::shared_ptr<Aws::IOStream> inputData = Aws::MakeShared<Aws::StringStream>("");
	inputData->write(content.data(), content.size());
	request.SetBody(inputData);
	int64 startTime = ::timeGetTime();
	Aws::S3::Model::PutObjectOutcome outcome = s3Client->PutObject(request);
	if (!outcome.IsSuccess()) {
		printf("upload to s3 error: %s", outcome.GetError().GetMessage().c_str());
		return -1;
	}
	else
		printf("upload to s3 ok: cost time: %lld ms", ::timeGetTime() - startTime);
	return 0;
}

Result

upload to s3 ok: cost time: 1150 ms

在这里插入图片描述

注

以上上传代码基于aws-sdk-cpp v1.6, 如果升级到较新的版本，需要更新相关API

clientConfig.caFile = "xxx.crt";
		Aws::Auth:s:AWSCredentials credentials(accessKey.c_str(), secret.c_str(), token.c_str());
s3Client = new Aws::S3::S3Client(credentials, nullptr, clientConfig);
