aws-sdk-cpp未定义类型Aws::Glacier::Model::GetDataRetrievalPolicyOutcome

Question

我使用通过NuGet获得的VS2015和aws-sdk-cpp 1.1.16 (核心版本)。当我尝试编译我的程序时，我得到了以下错误：Error C2027 use of undefined type 'Aws::Utils::Outcome<Aws::Glacier::Model::GetDataRetrievalPolicyResult,Aws::Client::AWSError<Aws::Glacier::GlacierErrors>>'

这是我的代码：

main.cpp

#include "stdafx.h"

int main()
{
    Aws::SDKOptions options;
    Aws::InitAPI(options);
    {
        Aws::Client::ClientConfiguration config;
        config.scheme = Aws::Http::Scheme::HTTPS;
        config.connectTimeoutMs = 30000;
        config.requestTimeoutMs = 30000;
        config.region = Aws::String(Aws::Region::EU_WEST_1);

        Aws::Glacier::GlacierClient client(config);
        Aws::Glacier::Model::GetDataRetrievalPolicyRequest request;
        Aws::Glacier::Model::GetDataRetrievalPolicyOutcome outcome = client.GetDataRetrievalPolicy(request);
        //^^^ error at this line
        if (outcome.IsSuccess()) {
            Aws::Vector<Aws::Glacier::Model::DataRetrievalRule> rules = outcome.GetResult().GetPolicy().GetRules();
            for (auto it : rules) {
                std::cout << it.GetStrategy() << std::endl;
            }
        }
        else {
            std::cout << "GetDataRetrievalPolicy error: "
                << outcome.GetError().GetExceptionName() << std::endl
                << outcome.GetError().GetMessage() << std::endl;
        }
    }
    Aws::ShutdownAPI(options);
    system("pause");
    return 0;
}

stdafx.h

#pragma once

#include <stdio.h>
#include <tchar.h>
#include <iostream>

#include <aws/acm/ACMClient.h>
#include <aws/core/Aws.h>
#include <aws/core/Region.h>

#include <aws/glacier/model/GetDataRetrievalPolicyResult.h>
#include <aws/glacier/model/DataRetrievalPolicy.h>
#include <aws/glacier/model/DataRetrievalRule.h>

我曾尝试用auto或Aws::Utils::Outcome<type_of_result, type_of_error>替换Aws::Glacier::Model::GetDataRetrievalPolicyOutcome，但无济于事

另外，我不能创建任何类型的Aws::Utils::Outcome<R,E>实例

另外，当我尝试包含#include <aws/core/utils/Outcome.h>时，我得到了以下错误：Error C2535 'Aws::Utils::Outcome<std::string,std::string>::Outcome(R &&)': member function already defined or declared ..\packages\awssdkcpp-core.1.1.16\build\native\include\aws\core\utils\outcome.h 50

Error C2535 'Aws::Utils::Outcome<std::string,std::string>::Outcome(const R &)': member function already defined or declared ..\packages\awssdkcpp-core.1.1.16\build\native\include\aws\core\utils\outcome.h 44

Answer 1

好的，当我将stdafx.h改为

#pragma once

#include <stdio.h>
#include <tchar.h>
#include <iostream>

#include <aws/core/Aws.h>
#include <aws/glacier/GlacierClient.h>
#include <aws/glacier/model/GetDataRetrievalPolicyRequest.h>
#include <aws/core/utils/Outcome.h>

一切都开始运转了
