AWS SDK for C++调用第三方S3 API

这里介绍AWS SDK for C++ 1.0.x版本，比如下载：

https://github.com/aws/aws-sdk-cpp/archive/1.0.164.tar.gz

环境：RHEL/CentOS 7

一、编译SDK

配置yum源：

[centos]

name=centos7

baseurl=http://mirrors.163.com/centos/7/os/x86_64/

enabled=1

gpgcheck=0

刷新源：yum makecache fast

安装EPEL源：yum -y install epel-release

再刷新源：yum makecache fast

安装必备软件和库：

yum -y erase cmake

yum -y install cmake3 gcc-c++ libstdc++-devel libcurl-devel zlib-devel

cd /usr/bin; ln -s cmake3 cmake

可能还会依赖其它库，根据编译时报的错误来判断安装哪个包。

准备源码：

tar -zxf 1.0..tar.gz -C /tmp

mkdir -p /tmp/build; cd /tmp/build

cmake -DCMAKE_BUILD_TYPE=Release /tmp/aws-sdk-cpp-1.0.

编译源码：

make -j `nproc` -C aws-cpp-sdk-core

make -j `nproc` -C aws-cpp-sdk-s3

安装头文件和库到一个目录：

mkdir -p /tmp/install

make install DESTDIR=/tmp/install -C aws-cpp-sdk-core

make install DESTDIR=/tmp/install -C aws-cpp-sdk-s3

二、编写示例代码

列出桶：

#include <iostream>

#include <aws/s3/S3Client.h>

#include <aws/core/Aws.h>

#include <aws/core/auth/AWSCredentialsProvider.h>

using namespace Aws::S3;

using namespace Aws::S3::Model;

using namespace std;

int main(int argc, char* argv[]) {

    Aws::SDKOptions options;

    options.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Trace;

    Aws::InitAPI(options);

    Aws::Client::ClientConfiguration cfg;

    cfg.endpointOverride = "10.202.91.2:88";  // S3服务器地址和端口

    cfg.scheme = Aws::Http::Scheme::HTTP;

    cfg.verifySSL = false;

    Aws::Auth::AWSCredentials cred("81BEB5DB4DED", "WzFGRTc34MzI5NjM0ODcxOUJDM0Jd");  // 认证的Key

    S3Client client(cred, cfg, false, false);

    auto response = client.ListBuckets();

    if (response.IsSuccess()) {

        auto buckets = response.GetResult().GetBuckets();

        for (auto iter = buckets.begin(); iter != buckets.end(); ++iter) {

            cout << iter->GetName() << "\t" << iter->GetCreationDate().ToLocalTimeString(Aws::Utils::DateFormat::ISO_8601) << endl;

        }

    } else {

        cout << "Error while ListBuckets " << response.GetError().GetExceptionName()

            << " " << response.GetError().GetMessage() << endl;

    }

    Aws::ShutdownAPI(options);

    return ;

}

三、编译示例代码并运行

g++ -std=c++ -I/tmp/install/usr/local/include -L/tmp/install/usr/local/lib64 -laws-cpp-sdk-core -laws-cpp-sdk-s3 a.cpp

export LD_LIBRARY_PATH=/tmp/install/usr/local/lib64

./a.out
