使用Amazon Educate Starter帐户将图像上传到S3 [英] Upload image to S3 with Amazon Educate Starter Account
问题描述
我只想将图像上传到S3,但是我使用的是AWS Educate帐户,并且自4个小时以来我一直在尝试完成此操作,并告诉ZERO哪些功能无法正常工作.
I just want to upload an image to S3, but I am using AWS Educate Account and I'm trying since 4 hours to get this done and have ZERO ideas what isn't working correctly.
因此,我已经在AWS控制台上进行了所有设置,并且存储桶对每个人+美国西弗吉尼亚北部地区都是公共的,就像它应该与AWS Educate Accounts一样.
So I've set up everything on the AWS console and the bucket is public to EVERYONE + Region US West N.Virginia like it should be with AWS Educate Accounts.
这是我的代码:
let accessKey = "accessKey"
let secretKey = "secretKey"
let credentialsProvider = AWSStaticCredentialsProvider(accessKey: accessKey, secretKey: secretKey)
let configuration = AWSServiceConfiguration(region: AWSRegionType.USEast1, credentialsProvider: credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
let transferUtility = AWSS3TransferUtility.default()
let bucketname = "bucketname"
let expression = AWSS3TransferUtilityUploadExpression()
transferUtility.uploadData(jpegData, bucket: bucketname, key: "myTransferUtilityUpload.jpg", contentType: "image/jpg", expression: expression) { (task, error) in
if let error = error {
print(error.localizedDescription)
}
if let response = task.response {
print(response)
}
}
谁能告诉我我做错了什么?
Can anyone tell me what I do wrong?
我收到此错误消息:
操作无法完成.(com.amazonaws.AWSS3TransferUtilityErrorDomain错误2.)
The operation couldn’t be completed. (com.amazonaws.AWSS3TransferUtilityErrorDomain error 2.)
accessKey + secretKey 我是从"Welcome to AWS Educate Starter Account"仪表板上的Account Details + AWS CLI中获得的,显然,存储桶名称与控制台中的名称相同
accessKey + secretKey I got from Account Details + AWS CLI on the 'Welcome to AWS Educate Starter Account' Dashboard and obviously the bucket name is the same name like in my console
if let jpegData = image.jpegData(compressionQuality: 0.7) {
let fileManager = FileManager.default
if let documentDirectory = fileManager.urls(for: .documentDirectory,
in: .userDomainMask).first {
var sourceFolderURL = documentDirectory.appendingPathComponent("image.jpg")
do {
try jpegData.write(to: sourceFolderURL)
} catch {
print(error.localizedDescription)
completionHandler(nil)
return
}
let accessKey = "-"
let secretKey = "-"
let bucketname = "-"
let credentialsProvider = AWSStaticCredentialsProvider(accessKey: accessKey, secretKey: secretKey)
let configuration = AWSServiceConfiguration(region: AWSRegionType.USEast1, credentialsProvider: credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
let uploadRequest = AWSS3TransferManagerUploadRequest()!
uploadRequest.body = sourceFolderURL
uploadRequest.key = "image.jpg"
uploadRequest.bucket = bucketname
uploadRequest.contentType = "image/jpeg"
uploadRequest.acl = .publicReadWrite
let transferManager = AWSS3TransferManager.default()
transferManager.upload(uploadRequest).continueWith { [weak self] (task) -> Any? in
if let error = task.error {
print("Upload failed with error: (\(error.localizedDescription))")
completionHandler(nil)
return nil
}
if task.result != nil {
let url = AWSS3.default().configuration.endpoint.url
let publicURL = url?.appendingPathComponent(uploadRequest.bucket!).appendingPathComponent(uploadRequest.key!)
if let absoluteString = publicURL?.absoluteString {
print("Uploaded to:\(absoluteString)")
completionHandler(nil)
}
}
completionHandler(nil)
return nil
}
}
}
推荐答案
我已使用以下代码将图像上传到S3存储桶:首先,将图像保存到临时目录.
I have uploaded an image to S3 bucket with the following code: First, save the image to a temporary directory.
func uploadImageToS3(imageName:String, completion:@escaping (Bool) -> Void) {
let accessKey = "accessKey"
let secretKey = "secretKey"
let credentialsProvider = AWSStaticCredentialsProvider(accessKey: accessKey, secretKey: secretKey)
let configuration = AWSServiceConfiguration(region:AWSRegionType.APSoutheast2, credentialsProvider:credentialsProvider)
AWSServiceManager.default().defaultServiceConfiguration = configuration
let S3BucketName = "bucketname"
let uploadRequest = AWSS3TransferManagerUploadRequest()!
uploadRequest.body = self.getImageURLWithName(imageName:imageName)
uploadRequest.key = "\(imageName)"
uploadRequest.bucket = S3BucketName
uploadRequest.contentType = "image/jpeg"
//You can specify private or public here
uploadRequest.acl = .private
let transferManager = AWSS3TransferManager.default()
transferManager.upload(uploadRequest).continueWith { [weak self] (task) -> Any? in
ProgressIndicatorHelper.hideGlobalHUD()
if let error = task.error {
print("Upload failed with error: (\(error.localizedDescription))")
completion(false)
}
if task.result != nil {
let url = AWSS3.default().configuration.endpoint.url
let publicURL = url?.appendingPathComponent(uploadRequest.bucket!).appendingPathComponent(uploadRequest.key!)
if let absoluteString = publicURL?.absoluteString {
print("Uploaded to:\(absoluteString)")
completion(true)
}
}
return nil
}
}
我使用以下代码从Path获取图像:
For getting image from Path following code I have used:
func getImageURLWithName(imageName:String) -> URL {
var sourceImageURL: URL!
let fileManager = FileManager.default
if let documentDirectory = fileManager.urls(for: .documentDirectory,
in: .userDomainMask).first {
var sourceFolderURL:URL!
sourceFolderURL = documentDirectory.appendingPathComponent("YourTempFolder")
sourceImageURL = sourceFolderURL.appendingPathComponent(imageName)
}
return sourceImageURL
}
希望这会有所帮助.
此外:目前,我不认为您可以直接从内存中上传图像.我搜寻了.以下是相同的链接: https://github.com/aws-amplify/aws-sdk-ios/issues/42
Moreover: Right now I don't think you can directly upload image from memory. I searched for it. Following are links for same: https://github.com/aws-amplify/aws-sdk-ios/issues/42
