问题描述
我正在开发一个需要将图像上传到S3的应用程序。现在我是这样的：
I'm working on an app which requires to upload images to S3. Now I am doing like this:
S3PutObjectRequest *por = [[S3PutObjectRequest alloc] initWithKey:nameOfThePicture inBucket:nameOfTheBucket];
por.contentType = @"image/jpg";
por.data = imageData;
// Put the image data into the specified s3 bucket and object.
S3PutObjectResponse *putObjectResponse = [self.s3 putObject:por];
por.delegate = self;
直接将图像上传到S3太慢了，我已经配置了CloudFront服务。 现在，我想通过CloudFront将图像上传到S3中的原始存储桶。有可能做到吗？如果是，我该怎么办？
Uploading an image directly to S3 is too slow and I have configured the CloudFront service. Now, I'd like to upload an image through CloudFront to the origin bucket in S3. Is possible to do it? If yes, how could I do it?
非常感谢，
Victor
推荐答案
否。 CloudFront是单向事务—您可以通过CloudFront从S3检索对象，但是不能通过CloudFront将对象上传到S3。
No. CloudFront is a one-way affair — you can retrieve objects from S3 through CloudFront, but you cannot upload objects to S3 through CloudFront.
