将数据库文件从ios上传到AWS s3问题

Question

Hi i try to upload a file to my bucket at AWS s3 without successes.

I just need to upload a file from some application from some phones.

i use AWS SDK version2 on ios 8.

this is my function for Upload a DB:

UPLOAD

 NSString *fileName = DB_File;
        NSString *directoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

    NSString *filePath = [directoryPath stringByAppendingPathComponent:fileName];
    NSData *fileData = [NSData dataWithContentsOfFile:filePath];





    AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager];
    AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
    uploadRequest.body = [NSURL fileURLWithPath:filePath];
    uploadRequest.key = fileName;
    uploadRequest.bucket = @"xxxx";

    [[transferManager upload:uploadRequest] continueWithBlock:^id(BFTask *task) {
        if (task.error) {
            if ([task.error.domain isEqualToString:AWSS3TransferManagerErrorDomain]) {
                switch (task.error.code) {
                    case AWSS3TransferManagerErrorCancelled:
                    case AWSS3TransferManagerErrorPaused:
                    {
                     NSLog(@"Upload failed: [%@]", task.error);
                    }
                        break;

                    default:
                        NSLog(@"Upload failed: [%@]", task.error);
                        break;
                }
            } else {
                NSLog(@"Upload failed: [%@]", task.error);
            }
        }

        if (task.result) {
            dispatch_async(dispatch_get_main_queue(), ^{
                NSLog(@"Upload ok: [%@]", task.error);
            });
        }
        return nil;
    }];

        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound categories:nil]];
    }
    AWSCognitoCredentialsProvider *credentialsProvider = [AWSCognitoCredentialsProvider
                                                          credentialsWithRegionType:AWSRegionxxxx
                                                          identityPoolId:@"us-xxxx-1:xxxxxx-xxxx-xxxx-xxxxx-xxxxxxx"];

    AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1
                                                                          credentialsProvider:credentialsProvider];

    [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;


    return YES;
}

Try changing your bucket policy to this (replace bucketName):

{
"Version": "2008-10-17",
"Id": "policy",
"Statement": [
    {
        "Sid": "allow-public-read",
        "Effect": "Allow",
        "Principal": {
            "AWS": "*"
        },
        "Action": "s3:GetObject",
        "Resource": "arn:aws:s3:::bucketName/*"
    },
    {
        "Sid": "allow-public-put",
        "Effect": "Allow",
        "Principal": {
            "AWS": "*"
        },
        "Action": "s3:PutObject",
        "Resource": "arn:aws:s3:::bucketName/*"
    }
]
}

This allows you to Add/Read objects from your bucket, you should read AWS S3 Documentation in order to know what exactly you want your policy to be, but for now, this should do the trick.

I give up on using AWS SDK . I have tried with AFAmazonS3Manager and It works well.

AFAmazonS3Manager : AFNetworking Client for the Amazon S3 API.
