How to upload a file to Amazon S3 and get the URL in response using iOS

Question

I used the code snippet from the Amazon code sample. The following code loads data into an Amazon S3 bucket, but I need the url of the download file. Am I going in the right direction? or can someone point me to the mistake I'm making

Any help is appreciated.

AWSS3TransferManager *transferManager = [AWSS3TransferManager defaultS3TransferManager]; AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new]; uploadRequest.bucket = S3BucketName; uploadRequest.key = S3UploadKeyName; uploadRequest.body = self.uploadFileURL; //uploadRequest.contentLength = [NSNumber numberWithUnsignedLongLong:fileSize]; [[transferManager upload:uploadRequest] continueWithBlock:^id(BFTask *task) { // Do something with the response AWSS3TransferManagerUploadOutput *uploadOutPut = task.result; NSLog(@"bftask:%@",uploadOutPut); // Upload out put gives me the following response return nil; }];

bfTask Response:

 bftask:<AWSS3TransferManagerUploadOutput: 0x1706606c0> { ETag = "\"0aefedfa36b687a74025b1ad50f3101f\""; serverSideEncryption = 0; }

If you just need to download the file, you can use AWSS3TransferManagerDownloadRequest to download the file using the SDK. Alternatively, you can use AWSS3PreSignedURLBuilder to create a pre-signed URL to download the file.

If you just want to know the URL of the object, the URL should look like this:

 https://<YourS3Endpoint>/<YourBucketName>/<YourObjectKeyName> 

Any objects in Amazon S3 are private by default and are not public. If you want to make it public, you need to set the ACL on your AWSS3TransferManagerUploadRequest object.
