批量删除指定前缀的文件

⚠ 请您谨慎使用删除操作，文件一旦删除将无法恢复。

批量删除指定前缀的文件。代码中需要引用"inspurcloud/oss/OssClient.h"类库，使用InspurCloud::OSS命名空间，并初始化账号信息AccessKeyId、AccessKeySecret、Endpoint，示例代码：

        //需要指定文件所在的桶以及前缀(prefix)
        std::string BucketName = "yourBucketName";
        std::string keyPrefix = "yourkeyPrefix ";

        //初始化网络等资源
        InitializeSdk();
        ClientConfiguration conf;
        OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);
        //删除文件
        DeleteObjectsRequest request(BucketName);
        auto outcome = client.DeleteObjects(request, keyPrefix);

        //处理结果 
        if (!outcome.isSuccess()) {
            std::cout << "DeleteObjects fail" << std::endl;
            std::cout << "error code:" << outcome.error().Code() << std::endl;
            std::cout << "error message:" << outcome.error().Message() << std::endl;
            std::cout << "requestId:" << outcome.error().RequestId() << std::endl;
            ShutdownSdk();
            return -1;
        }
        else {
            std::cout << "DeleteObject Success！" << std::endl;
        }

        //释放资源
        ShutdownSdk();
