一、准备工作
在开始编译AWS SDK C库之前请确保您的系统已经安装了以下依赖项 CMake版本3.13或更高版本 支持C11的编译器我是使用的是MSVC 2017 64位
二、下载AWS SDK C源代码
首先您需要从GitHub上的AWS SDK C存储库下载源代码。您可以通过以下命令克隆存储库
git clone --recurse-submodules https://github.com/aws/aws-sdk-cpp
cd aws-sdk-cpp三、配置编译环境
接下来您需要使用CMake来配置编译环境。这将生成适用于您的系统的构建文件。您可以通过以下命令来配置编译环境
mkdir BUILD_DIR
cd BUILD_DIR
# 编译Release版本
cmake ..\aws-sdk-cpp -G Visual Studio 15 2017 Win64 -DCMAKE_BUILD_TYPERelease -DBUILD_ONLYs3
# 开始编译
cmake --build . --configRelease
# 安装到指定目录需要管理员权限
cmake --install . --configReleasecmake --install 会把库文件安装到 C:\Program Files\aws-cpp-sdk-all 目录
四、编译测试代码验证
4.1 创建hello_s3.cpp文件
#include aws/core/Aws.h
#include aws/s3/S3Client.h
#include iostream
#include aws/core/auth/AWSCredentialsProviderChain.h
using namespace Aws;
using namespace Aws::Auth;/** A Hello S3 starter application which initializes an Amazon Simple Storage Service (Amazon S3) client* and lists the Amazon S3 buckets in the selected region.** main function** Usage: hello_s3**/int main(int argc, char **argv) {Aws::SDKOptions options;// Optionally change the log level for debugging.
// options.loggingOptions.logLevel Utils::Logging::LogLevel::Debug;Aws::InitAPI(options); // Should only be called once.int result 0;{Aws::Client::ClientConfiguration clientConfig;// Optional: Set to the AWS Region (overrides config file).// clientConfig.region us-east-1;// You dont normally have to test that you are authenticated. But the S3 service permits anonymous requests, thus the s3Client will return success and 0 buckets even if you are unauthenticated, which can be confusing to a new user. auto provider Aws::MakeSharedDefaultAWSCredentialsProviderChain(alloc-tag);auto creds provider-GetAWSCredentials();if (creds.IsEmpty()) {std::cerr Failed authentication std::endl;}Aws::S3::S3Client s3Client(clientConfig);auto outcome s3Client.ListBuckets();if (!outcome.IsSuccess()) {std::cerr Failed with error: outcome.GetError() std::endl;result 1;} else {std::cout Found outcome.GetResult().GetBuckets().size() buckets\n;for (auto bucket: outcome.GetResult().GetBuckets()) {std::cout bucket.GetName() std::endl;}}}Aws::ShutdownAPI(options); // Should only be called once.return result;
}
4.2 创建CmakeLists.txt
# Set the minimum required version of CMake for this project.
cmake_minimum_required(VERSION 3.13)# Set the AWS service components used by this project.
set(SERVICE_COMPONENTS s3)# Set this projects name.
project(hello_s3)# Set the C standard to use to build this target.
# At least C 11 is required for the AWS SDK for C.
set(CMAKE_CXX_STANDARD 11)# Use the MSVC variable to determine if this is a Windows build.
set(WINDOWS_BUILD ${MSVC})if (WINDOWS_BUILD) # Set the location where CMake can find the installed libraries for the AWS SDK.string(REPLACE ; /aws-cpp-sdk-all; SYSTEM_MODULE_PATH ${CMAKE_SYSTEM_PREFIX_PATH}/aws-cpp-sdk-all)list(APPEND CMAKE_PREFIX_PATH ${SYSTEM_MODULE_PATH})
endif ()# Find the AWS SDK for C package.
find_package(AWSSDK REQUIRED COMPONENTS ${SERVICE_COMPONENTS})if (WINDOWS_BUILD AND AWSSDK_INSTALL_AS_SHARED_LIBS)# Copy relevant AWS SDK for C libraries into the current binary directory for running and debugging.# set(BIN_SUB_DIR /Debug) # if you are building from the command line you may need to uncomment this# and set the proper subdirectory to the executables location.AWSSDK_CPY_DYN_LIBS(SERVICE_COMPONENTS ${CMAKE_CURRENT_BINARY_DIR}${BIN_SUB_DIR})
endif ()add_executable(${PROJECT_NAME}hello_s3.cpp)target_link_libraries(${PROJECT_NAME}${AWSSDK_LINK_LIBRARIES})
4.3 使用cmake构建
mkdir my_project_build
cd my_project_build
cmake ../# 然后运行hello_s3
./hello_s3hello_s3会打印出所有bucket名字前提是已经配置了AWS的凭证。
