管理软链接（C++ SDK V2）

注意事项

• 运行示例代码前，请将代码中的 <region> 替换为实际的地域，如 cn-hangzhou。

• 本文示例代码使用环境变量获取访问凭证。

• 创建软链接需要拥有 oss:PutObject 权限。

• 获取软链接需要拥有 oss:GetObject 权限。

示例代码

#include <iostream>
#include "alibabacloud/oss2/ClientConfiguration.h"
#include "alibabacloud/oss2/OSSClient.h"
#include "alibabacloud/oss2/credentials/CredentialsProvider.h"

namespace oss = alibabacloud::oss2;

int main() {
    auto conf = oss::ClientConfiguration::loadDefault();
    conf.region = "<region>";
    conf.credentialsProvider = std::make_shared<oss::EnvironmentVariableCredentialsProvider>();

    oss::OSSClient client(conf);

    auto outcome = client.putSymlink(
        oss::models::PutSymlinkRequest()
            .setBucket("examplebucket")
            .setKey("example-symlink.txt")
            .setSymlinkTarget("exampleobject.txt"));

    if (!outcome.has_value()) {
        auto& e = outcome.error();
        std::cerr << "创建软链接失败"
                  << ", code: " << e.getCode()
                  << ", message: " << e.getMessage()
                  << ", requestId: " << e.getRequestId() << std::endl;
        return 1;
    }

    auto& result = outcome.value();
    std::cout << "创建软链接成功"
              << ", status: " << result.getStatusCode()
              << ", requestId: " << result.getRequestId() << std::endl;
    return 0;
}

        return 1;
    }

    auto& result = outcome.value();
    std::cout << "获取软链接成功"
              << ", 目标文件: " << result.getSymlinkTarget() << std::endl;
    return 0;
