您可以通过标签(Tags)标记不同用途的存储空间(Bucket),并对Bucket进行分类管理。
注意事项
本文以华东1(杭州)外网Endpoint为例。如果您希望通过与OSS同地域的其他阿里云产品访问OSS,请使用内网Endpoint。关于OSS支持的Region与Endpoint的对应关系,请参见OSS地域和访问域名。
本文以OSS域名新建OSSClient为例。如果您希望通过自定义域名、STS等方式新建OSSClient,请参见新建OssClient。
只有Bucket拥有者及授予
oss:PutBucketTagging
权限的用户才能为Bucket设置标签,否则返回403 Forbidden错误,错误码为AccessDenied。每个Bucket最多可设置20个标签(Key-Value对)。
Key和Value必须为UTF-8编码。
Key最大长度为64字符,区分大小写,不能为空。Key不支持以
http://
、https://
、Aliyun
为前缀(不区分大小写)。Value最大长度为128字符,可以为空。
设置Bucket标签
以下代码用于为examplebucket存储空间设置标签。
#include <alibabacloud/oss/OssClient.h>
using namespace AlibabaCloud::OSS;
int main(void)
{
/*初始化OSS账号信息。*/
/*yourEndpoint填写Bucket所在地域对应的Endpoint。以华东1(杭州)为例,Endpoint填写为https://oss-cn-hangzhou.aliyuncs.com。*/
std::string Endpoint = "yourEndpoint";
/ *yourRegion填写Bucket所在地域对应的Region。以华东1(杭州)为例,Region填写为cn - hangzhou。 * /
std::string Region = "yourRegion";
/*填写Bucket名称,例如examplebucket。*/
std::string BucketName = "examplebucket";
/*初始化网络等资源。*/
InitializeSdk();
ClientConfiguration conf;
conf.signatureVersion = SignatureVersionType::V4;
/* 从环境变量中获取访问凭证。运行本代码示例之前,请确保已设置环境变量OSS_ACCESS_KEY_ID和OSS_ACCESS_KEY_SECRET。*/
auto credentialsProvider = std::make_shared<EnvironmentVariableCredentialsProvider>();
OssClient client(Endpoint, credentialsProvider, conf);
client.SetRegion(Region);
/*设置Bucket标签。*/
SetBucketTaggingRequest request(BucketName);
Tag tag1("yourTagkey1","yourTagValue1");
Tag tag2("yourTagkey2", "yourTagValue2");
TagSet tagset;
tagset.push_back(tag1);
tagset.push_back(tag2);
Tagging taging;
taging.setTags(tagset);
request.setTagging(taging);
auto outcome = client.SetBucketTagging(request);
if (outcome.isSuccess()) {
std::cout << " SetBucketTagging success " << std::endl;
}
else {
/*异常处理。*/
std::cout << "SetBucketTagging fail" <<
",code:" << outcome.error().Code() <<
