使用API​​启用存储桶中的库存（iOS上为SDK）

Question

我正在尝试使用AWS开发工具包iOS 2.6.21在存储桶中以编程方式启用清单配置。我正在为存储桶所在的正确区域设置我的凭据（秘密密钥和访问ID）（我已经测试了它的工作原理，因为我能够获取存储桶版本控制等）。但是，当我尝试在存储桶上启用库存配置时，出现错误消息问题：

成品存放区库存（空）-错误错误Domain = com.amazonaws.AWSServiceErrorDomain代码= 3“（空）” UserInfo = {Message =我们计算出的请求签名与您提供的签名不匹配。检查您的密钥和签名方法。

我的猜测是我在配置请求中缺少必需的参数，但是我无法弄清楚哪个参数。我也没有找到任何有关如何执行此操作的示例，因此我希望有人可以查看我的Objective-C代码并将其定向到我所缺少的内容。谢谢。干杯，特隆德

-(AWSTask*) putBucketInventory:(SDS3Bucket*)bucketObject region:(NSString*) region{

AWSS3PutBucketInventoryConfigurationRequest *putBucketInventoryRequest = 
[AWSS3PutBucketInventoryConfigurationRequest new];
 putBucketInventoryRequest.bucket = bucketObject.name;
 putBucketInventoryRequest.identifier=@"TestInventory";
 putBucketInventoryRequest.inventoryConfiguration= . 
 [AWSS3InventoryConfiguration new];
 putBucketInventoryRequest.inventoryConfiguration.isEnabled=@(YES);
 putBucketInventoryRequest.inventoryConfiguration.identifier=
 @"TestInventory";
 AWSS3InventoryFilter *filter=[AWSS3InventoryFilter new];
 filter.prefix=@"";
 putBucketInventoryRequest.inventoryConfiguration.filter=filter;

 AWSS3InventoryS3BucketDestination *s3dest= 
 [AWSS3InventoryS3BucketDestination new];
 AWSS3InventoryEncryption *enc = [AWSS3InventoryEncryption new];

 AWSS3SSES3 *sses3=[AWSS3SSES3 new];
 enc.SSES3=sses3;
 s3dest.encryption=enc;

 s3dest.accountId=bucketObject.owner.identifier;
 s3dest.bucket=[NSString 
 stringWithFormat:@"arn:aws:s3:::%@",bucketObject.name];
 s3dest.format=AWSS3InventoryFormatCsv;
 s3dest.prefix=@"inventory";

 AWSS3InventoryDestination *destination=[AWSS3InventoryDestination new];
 destination.s3BucketDestination=s3dest;

 putBucketInventoryRequest.inventoryConfiguration.destination=
 destination;
 AWSS3InventorySchedule *schedule=[AWSS3InventorySchedule new];
 schedule.frequency=AWSS3InventoryFrequencyDaily;
 putBucketInventoryRequest.inventoryConfiguration.schedule=schedule;


 putBucketInventoryRequest.inventoryConfiguration
.includedObjectVersions=AWSS3InventoryIncludedObjectVersionsCurrent;
putBucketInventoryRequest.inventoryConfiguration.optionalFields=
@[@"Size",
@"LastModifiedDate",

@"EncryptionStatus"];

return [[[AWSS3 S3ForKey:region] 
putBucketInventoryConfiguration:putBucketInventoryRequest] 
 continueWithSuccessBlock:^id(AWSTask *task) {
     if(task.error != nil){
         NSLog(@"The request failed. error: [%@]", task.error);
     }  
     return task;
 }];
}

ps。我还在AWS SDK iOS Github site
