本文介绍如何删除文件。

警告 请您谨慎使用删除操作，文件一旦删除将无法恢复。

删除单个文件

以下代码用于删除单个文件：

#include <alibabacloud/oss/OssClient.h>
using namespace AlibabaCloud::OSS;

int main(void)
{
     /* 初始化OSS账号信息 */
    std::string AccessKeyId = "yourAccessKeyId";
    std::string AccessKeySecret = "yourAccessKeySecret";
    std::string Endpoint = "yourEndpoint";
    std::string BucketName = "yourBucketName";
    std::string ObjectName = "yourObjectName";

    /* 初始化网络等资源 */
    InitializeSdk();

    ClientConfiguration conf;
    OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);

    /* ObjectName表示删除OSS文件时需要指定包含文件后缀在内的完整路径，例如abc/efg/123.jpg */
    /* 如需删除文件夹，请将ObjectName设置为对应的文件夹名称。如果文件夹非空，则需要将文件夹下的所有object删除后才能删除该文件夹 */
    DeleteObjectRequest request(BucketName, ObjectName);

    /* 删除文件 */
    auto outcome = client.DeleteObject(request);

    if (!outcome.isSuccess()) {
        /* 异常处理 */
        std::cout << "DeleteObject fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        ShutdownSdk();
        return -1;
    }

    /* 释放网络等资源 */
    ShutdownSdk();
    return 0;
}

删除多个文件

以下代码用于批量删除文件：

#include <alibabacloud/oss/OssClient.h>
using namespace AlibabaCloud::OSS;

int main(void)
{
     /*初始化OSS账号信息*/
    std::string AccessKeyId = "yourAccessKeyId";
    std::string AccessKeySecret = "yourAccessKeySecret";
    std::string Endpoint = "yourEndpoint";
    std::string BucketName = "yourBucketName";
    std::string ObjectName = "yourObjectName";

    /* 初始化网络等资源 */
    InitializeSdk();

    ClientConfiguration conf;
    OssClient client(Endpoint, AccessKeyId, AccessKeySecret, conf);

    DeleteObjectsRequest request(BucketName);
    /* 添加要删除文件的文件名 */
    request.addKey(ObjectName);

    /* 删除文件 */
    auto outcome = client.DeleteObjects(request);

    if (!outcome.isSuccess()) {
        /* 异常处理 */
        std::cout << "DeleteObjects fail" <<
        ",code:" << outcome.error().Code() <<
        ",message:" << outcome.error().Message() <<
        ",requestId:" << outcome.error().RequestId() << std::endl;
        ShutdownSdk();
        return -1;
    }

    /* 释放网络等资源 */
    ShutdownSdk();
    return 0;
}
