在swift中上传图像AWS S3存储桶
我试图上传一个图像到一个桶S3 AWS，我正在使用下面的代码。 但我用它来上传到一个图像存储在一个variables或imageView.image？
let ext = "jpg" let imageURL = NSBundle.mainBundle().URLForResource("imagename", withExtension: ext) print("imageURL:\(imageURL)") let uploadRequest = AWSS3TransferManagerUploadRequest() uploadRequest.body = imageURL uploadRequest.key = NSProcessInfo.processInfo().globallyUniqueString + "." + ext uploadRequest.bucket = S3BucketName uploadRequest.contentType = "image/" + ext let transferManager = AWSS3TransferManager.defaultS3TransferManager() transferManager.upload(uploadRequest).continueWithBlock { (task) -> AnyObject! in if let error = task.error { print("Upload failed ❌ (\(error))") } if let exception = task.exception { print("Upload failed ❌ (\(exception))") } if task.result != nil { let s3URL = NSURL(string: "http://s3.amazonaws.com/\(self.S3BucketName)/\(uploadRequest.key!)")! print("Uploaded to:\n\(s3URL)") } else { print("Unexpected empty result.") } return nil } 我修改了你的代码，试试这个
let ext = "jpg" let imageURL = NSBundle.mainBundle().URLForResource("imagename", withExtension: ext) print("imageURL:\(imageURL)") let uploadRequest = AWSS3TransferManagerUploadRequest() uploadRequest.body = imageURL uploadRequest.key = "\(NSProcessInfo.processInfo().globallyUniqueString).\(ext)" uploadRequest.bucket = S3BucketName uploadRequest.contentType = "image/\(ext)" let transferManager = AWSS3TransferManager.defaultS3TransferManager() transferManager.upload(uploadRequest).continueWithBlock { (task) -> AnyObject! in if let error = task.error { print("Upload failed ❌ (\(error))") } if let exception = task.exception { print("Upload failed ❌ (\(exception))") } if task.result != nil { let s3URL = NSURL(string: "http://s3.amazonaws.com/\(self.S3BucketName)/\(uploadRequest.key!)")! print("Uploaded to:\n\(s3URL)") } else { print("Unexpected empty result.") } return nil }
或者你可以使用我的代码下载到AWS s3，它对我来说工作的很好。 这段代码是用swift写成的。
func uploadButtonPressed(_ sender: AnyObject) { if documentImageView.image == nil { // Do something to wake up user :) } else { let image = documentImageView.image! let fileManager = FileManager.default let path = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent("\(imageName!).jpeg") let imageData = UIImageJPEGRepresentation(image, 0.99) fileManager.createFile(atPath: path as String, contents: imageData, attributes: nil) let fileUrl = NSURL(fileURLWithPath: path) var uploadRequest = AWSS3TransferManagerUploadRequest() uploadRequest?.bucket = "BucketName" uploadRequest?.key = "key.jpeg" uploadRequest?.contentType = "image/jpeg" uploadRequest?.body = fileUrl as URL! uploadRequest?.serverSideEncryption = AWSS3ServerSideEncryption.awsKms uploadRequest?.uploadProgress = { (bytesSent, totalBytesSent, totalBytesExpectedToSend) -> Void in DispatchQueue.main.async(execute: { self.amountUploaded = totalBytesSent // To show the updating data status in label. self.fileSize = totalBytesExpectedToSend }) } let transferManager = AWSS3TransferManager.default() transferManager?.upload(uploadRequest).continue(with: AWSExecutor.mainThread(), withSuccessBlock: { (taskk: AWSTask) -> Any? in if taskk.error != nil { // Error. } else { // Do something with your result. } return nil }) }
}
谢谢！ 🙂
这是图像上传使用AWS S3桶下面的代码我实现了图像上传从画廊上传
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) { if(picker.sourceType == UIImagePickerControllerSourceType.PhotoLibrary) { selectedImageUrl = info[UIImagePickerControllerReferenceURL] as!
