windos下QT调取： error: no member named 'GetObjectW' in 'AlibabaCloud::OSS::OssClient'

[zhongguanLiu]

E:\QTProjects\StackedWidget\mainwindow.cpp:342: error: no member named 'GetObjectW' in 'AlibabaCloud::OSS::OssClient' E:\QTProjects\StackedWidget\mainwindow.cpp:342: error: 'class AlibabaCloud::OSS::OssClient' has no member named 'GetObjectW'; did you mean 'GetObject'? auto outcome = client.GetObject(request); ^ 我才用CMake+vs2022编译，看样子库配置没有问题，出在了重载上。但是我在调用#include <alibabacloud/oss/OssClient.h>之前使用 **#undef GetObject

undef GetObjectW

undef GetObjectA**

却没有起到任何效果！ 实在是不理解了！请各位大师指条路。 ” void MainWindow::on_network_uodate_clicked() { // OSS账号信息初始化 std::string Endpoint = "https://oss-cn-hangzhou.aliyuncs.com"; std::string BucketName = "examplebucket"; std::string ObjectName = "exampledir/exampleobject.txt"; std::string FileNametoSave = "D:\localpath\examplefile.txt";

// 初始化网络等资源
ACOSS::InitializeSdk();

ACOSS::ClientConfiguration conf;
// 从环境变量中获取访问凭证
auto credentialsProvider = std::make_shared<ACOSS::EnvironmentVariableCredentialsProvider>();
ACOSS::OssClient client(Endpoint, credentialsProvider, conf);

// 下载Object到本地文件
ACOSS::GetObjectRequest request(BucketName, ObjectName);
request.setResponseStreamFactory([=]() {
    return std::make_shared<std::fstream>(FileNametoSave, std::ios_base::out | std::ios_base::in | std::ios_base::trunc | std::ios_base::binary);
});

**auto outcome = client.GetObject(request);**

if (outcome.isSuccess()) {
    std::cout << "GetObjectToFile success, size: " << outcome.result().Metadata().ContentLength() << " bytes" << std::endl;
} else {
    // 异常处理
    std::cout << "GetObjectToFile fail" <<
    ",code:" << outcome.error().Code() <<
    ",message:" << outcome.error().Message() <<
    ",requestId:" << outcome.error().RequestId() << std::endl;
}

// 释放网络等资源
AlibabaCloud::OSS::ShutdownSdk();

} “

只有 GetObject 是宏吧，GetObjectA 和 GetObjectW 都是函数。

#ifdef GetObject
#undef GetObject
#endif

你是不是在这个 undef 之后又引用了 windows 的哪个头文件？

同样遇到了这个问题，能不能不要跟系统定义的宏起一样的名字啊
