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 1.0.164.tar.gz -C /tmp
mkdir -p /tmp/build; cd /tmp/build
cmake -DCMAKE_BUILD_TYPE=Release /tmp/aws-sdk-cpp-1.0.164

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 0;
}

 

三、编译示例代码并运行

g++ -std=c++11 -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
