AWS S3에 이미지 업로드 하기

 

카메라 촬영을 통한 결과를 FileManager의 document directory에 저장하고, 그 경로를 URL 형식으로 변환하여 S3를 업로드하는 내용입니다.

 

코코아팟 설치를 해줍니다.

 # AWS
  pod 'AWSS3', '~> 2.27.1'

 

 

poolId를 발급받아 AWSCognitoCredentialsProvider과 AWSServiceConfiguration을 생성 후, Default Service Configuration을 이니셜라이징 해줍니다.

func configure() {
    let credentialsProvider = AWSCognitoCredentialsProvider(regionType: .APNortheast2, identityPoolId: "INSERT-POOL-ID-HERE")
    guard let configuration = AWSServiceConfiguration(region: .APNortheast2, credentialsProvider: credentialsProvider) else { return }

    AWSServiceManager.default().defaultServiceConfiguration = configuration
}

 

 

버킷네임과 키값으로 넣을 path 그리고 기타 contentType을 설정하여 파일을 업로드합니다.

let bucketName = "BUCKET_NAME"
var completionHandler: AWSS3TransferUtilityUploadCompletionHandlerBlock?

func upload() {
    let fileUrl = URL(fileURLWithPath: "PATH")

    let expression  = AWSS3TransferUtilityUploadExpression()
    expression.progressBlock = { (task: AWSS3TransferUtilityTask,progress: Progress) -> Void in
        print(progress.fractionCompleted)   //2
        if progress.isFinished{           //3
            print("Upload Finished...")
            //do any task here.
        }
    }

    expression.setValue("public-read-write", forRequestHeader: "x-amz-acl")

    completionHandler = { task, error -> Void in
        if let _ = error {
            print("Failure uploading file")
        } else {
            print("Success uploading file")
        }
    }

    AWSS3TransferUtility.default().uploadFile(fileUrl, bucket: bucketName, key: "Path", contentType: "image/png", expression: expression, completionHandler: completionHandler).continueWith { task -> AnyObject? in

        if let _ = task.error {
            print("Error uploading file: \(String(describing: task.error?.localizedDescription))")
        }

        if let _ = task.result {
            print("start upload...")
        }
        return nil
    }
}

 

 

그런데 업로드를 하는 도중, 이런 에러가 나옵니다.

com.amazonaws.AWSCognitoIdentityErrorDomain error 10

 

 

 

 

처음 이니셜라이징할때 리전타입을 잘못 입력했었습니다.

func configure() {
    let credentialsProvider = AWSCognitoCredentialsProvider(regionType: .APNortheast2, identityPoolId: "INSERT-POOL-ID-HERE") 
    guard let configuration = AWSServiceConfiguration(region: .APNortheast2, credentialsProvider: credentialsProvider) else { return }

    AWSServiceManager.default().defaultServiceConfiguration = configuration
}

 

 

 

 

Info.plist를 소스 코드 보기로 변경하여 AWS 관련 설정들을 입력해줍니다.

사진을 촬영 후, 다시 s3에 업로드해봅니다.

아래와 같이 이미지 파일이 업로드된 것을 확인할 수 있습니다.
