Setting Bucket Tags

Feature description

This API is used to set tags for an existing bucket.

Sample code

Objective-C
QCloudPutBucketTaggingRequest *putReq = [QCloudPutBucketTaggingRequest new];

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
putReq.bucket = @"examplebucket-1250000000";

// Set of tags
QCloudTagging *taggings = [QCloudTagging new];

QCloudTag *tag1 = [QCloudTag new];

// Tag key; this value can contain up to 128 bytes of letters, digits, spaces, plus signs, minus signs, underscores, equal signs, dots,
// colons, and slashes
tag1.key = @"age";

// Tag value; this value can contain up to 256 bytes of letters, digits, spaces, plus signs, minus signs, underscores, equal signs, dots,
// colons, and slashes
tag1.value = @"20";
QCloudTag *tag2 = [QCloudTag new];
tag2.key = @"name";
tag2.value = @"karis";

// Set of tags. Up to 10 tags are supported
QCloudTagSet *tagSet = [QCloudTagSet new];
tagSet.tag = @[tag1,tag2];
taggings.tagSet = tagSet;

// Set of tags
putReq.taggings = taggings;

[putReq setFinishBlock:^(id outputObject, NSError *error) {
    // `outputObject` contains all the HTTP response headers
    NSDictionary* info = (NSDictionary *) outputObject;
}];
[[QCloudCOSXMLService defaultCOSXML] PutBucketTagging:putReq];
Note:
For the complete sample, go to GitHub.
Swift
let req = QCloudPutBucketTaggingRequest.init();

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
req.bucket = "examplebucket-1250000000";
let taggings = QCloudTagging.init();

// Set of tags
let tagSet = QCloudTagSet.init();
taggings.tagSet = tagSet;
let tag1 = QCloudTag.init();

// Tag key; this value can contain up to 128 bytes of letters, digits, spaces, plus signs, minus signs, underscores, equal signs, dots,
// colons, and slashes
tag1.key = "age";

// Tag value; this value can contain up to 256 bytes of letters, digits, spaces, plus signs, minus signs, underscores, equal signs, dots,
// colons, and slashes
tag1.value = "20";

let tag2 = QCloudTag.init();
tag2.key = "name";
tag2.value = "karis";

// Set of tags. Up to 10 tags are supported
tagSet.tag = [tag1,tag2];

// Set of tags
req.taggings = taggings;
req.finishBlock = {(result,error) in
    if let result = result {
        // result contains response headers
    } else {
        print(error!);
    }
}
QCloudCOSXMLService.defaultCOSXML().putBucketTagging(req);

Querying Bucket Tags

Feature description

This API is used to query the existing tags of a specified bucket.

Sample code

Objective-C
QCloudGetBucketTaggingRequest *getReq = [QCloudGetBucketTaggingRequest new];

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
getReq.bucket = @"examplebucket-1250000000";

[getReq setFinishBlock:^(QCloudBucketTagging * result, NSError * error) {
    // Set of tags
    QCloudTagSet * tagSet = result.tagSet;
}];
[[QCloudCOSXMLService defaultCOSXML] GetBucketTagging:getReq];
Note:
For the complete sample, go to GitHub.
Swift
let req = QCloudGetBucketTaggingRequest.init();

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
req.bucket = "examplebucket-1250000000";
req.setFinish { (result, error) in
    if let result = result {
        // Set of tags
        let tagSet = result.tagSet
    } else {
        print(error!);
    }
};
QCloudCOSXMLService.defaultCOSXML().getBucketTagging(req);
Note:

Deleting Bucket Tags

Feature description

This API (DELETE Bucket tagging) is used to delete the existing tags from a bucket.

Sample code

Objective-C
QCloudDeleteBucketTaggingRequest *delReq = [QCloudDeleteBucketTaggingRequest new];

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
delReq.bucket =  @"examplebucket-1250000000";

[delReq setFinishBlock:^(id outputObject, NSError *error) {
    // outputObject contains all the HTTP response headers
    NSDictionary* info = (NSDictionary *) outputObject;
}];
[[QCloudCOSXMLService defaultCOSXML] DeleteBucketTagging:delReq];
Note:
For the complete sample, go to GitHub.
Swift
let req = QCloudDeleteBucketTaggingRequest.init();

// Bucket name in the format of BucketName-APPID, which can be viewed in the COS console at https://console.cloud.tencent.com/cos5/bucket.
req.bucket = "examplebucket-1250000000";
req.finishBlock =  { (result, error) in
    if let result = result {
        // result contains response headers
    } else {
        print(error!);
    }
};
QCloudCOSXMLService.defaultCOSXML().deleteBucketTagging(req);
