删除对象

功能说明

删除指定的对象（DELETE Object）。

示例代码一：删除单个对象

Objective-C

QCloudDeleteObjectRequest* deleteObjectRequest = [QCloudDeleteObjectRequest new];
// 存储桶名称，由BucketName-Appid 组成，可以在COS控制台查看 https://console.cloud.tencent.com/cos5/bucketdeleteObjectRequest.bucket = @"examplebucket-1250000000";

// 对象键，是对象在 COS 上的完整路径，如果带目录的话，格式为 "video/xxx/movie.mp4"deleteObjectRequest.object = @"exampleobject";
[deleteObjectRequest setFinishBlock:^(id outputObject, NSError *error) {    // outputObject 包含所有的响应 http 头部    NSDictionary* info = (NSDictionary *) outputObject;}];
[[QCloudCOSXMLService defaultCOSXML] DeleteObject:deleteObjectRequest];

let deleteObject = QCloudDeleteObjectRequest.init();
// 存储桶名称，由BucketName-Appid 组成，可以在COS控制台查看 https://console.cloud.tencent.com/cos5/bucketdeleteObject.bucket = "examplebucket-1250000000";

// 对象键，是对象在 COS 上的完整路径，如果带目录的话，格式为 "video/xxx/movie.mp4"deleteObject.object = "exampleobject";
deleteObject.finishBlock = {(result,error)in    if let result = result {        // result 包含响应的 header 信息    } else {        print(error!);    }}QCloudCOSXMLService.defaultCOSXML().deleteObject(deleteObject);

示例代码二：删除目录

Objective-C

QCloudGetBucketRequest* request = [QCloudGetBucketRequest new];// 存储桶名称，由BucketName-Appid 组成，可以在COS控制台查看 https://console.cloud.tencent.com/cos5/bucketrequest.bucket = @"examplebucket-1250000000";// 单次返回的最大条目数量，默认1000request.maxKeys = 100;
//要删除的目录名称：带'/'request.prefix = @"prefix";
[request setFinishBlock:^(QCloudListBucketResult * result, NSError* error) {    if(!error){        NSMutableArray *deleteInfosArr = [NSMutableArray array];        for (QCloudBucketContents *content in result.contents) {            QCloudDeleteMultipleObjectRequest *delteRequest = [QCloudDeleteMultipleObjectRequest new];            delteRequest.bucket = request.bucket;
            QCloudDeleteObjectInfo *object = [QCloudDeleteObjectInfo new];            object.key = content.key;            [deleteInfosArr addObject:object];        }
        QCloudDeleteInfo *deleteInfos = [QCloudDeleteInfo new];        deleteInfos.objects = [deleteInfosArr copy];
        QCloudDeleteMultipleObjectRequest *delteRequest = [QCloudDeleteMultipleObjectRequest new];        delteRequest.bucket = @"examplebucket-1250000000";        delteRequest.deleteObjects = deleteInfos;        [delteRequest setFinishBlock:^(QCloudDeleteResult *outputObject, NSError *error) {            NSLog(@"outputObject = %@",outputObject);        }];
        [[QCloudCOSXMLService defaultCOSXML] DeleteMultipleObject:delteRequest];
    }}];
[[QCloudCOSXMLService defaultCOSXML] GetBucket:request];

        // 封装了需要批量删除的多个对象的信息        mutipleDel.deleteObjects = deleteInfos;

删除多个对象

功能说明

批量删除多个对象（DELETE Multiple Objects）。

示例代码一：批量删除对象

Objective-C

QCloudDeleteMultipleObjectRequest* delteRequest = [QCloudDeleteMultipleObjectRequest new];delteRequest.bucket = @"examplebucket-1250000000";
// 要删除的单个文件QCloudDeleteObjectInfo* deletedObject0 = [QCloudDeleteObjectInfo new];
// 对象键，是对象在 COS 上的完整路径，如果带目录的话，格式为 "video/xxx/movie.mp4"deletedObject0.key = @"exampleobject";
// 要删除的文件集合QCloudDeleteInfo* deleteInfo = [QCloudDeleteInfo new];
// 布尔值，这个值决定了是否启动 Quiet 模式：// true：启动 Quiet 模式// false：启动 Verbose 模式// 默认值为 FalsedeleteInfo.quiet = NO;
// 存放需要删除对象信息的数组deleteInfo.objects = @[deletedObject0];
// 封装了需要批量删除的多个对象的信息delteRequest.deleteObjects = deleteInfo;
[delteRequest setFinishBlock:^(QCloudDeleteResult* outputObject,                               NSError *error) {    // 可以从 outputObject 中获取 response 中 etag 或者自定义头部等信息
}];
[[QCloudCOSXMLService defaultCOSXML] DeleteMultipleObject:delteRequest];

let mutipleDel = QCloudDeleteMultipleObjectRequest.init();
// 存储桶名称，由BucketName-Appid 组成，可以在COS控制台查看 https://console.cloud.tencent.com/cos5/bucketmutipleDel.bucket = "examplebucket-1250000000";
// 要删除的单个文件let info1 = QCloudDeleteObjectInfo.init();
