问题
I have a script (PHP) that stores an image uploaded by a user to my server. After it is uploaded (which involves some processing) I want to move that processed file to S3.
Just to be clear, here is what I would like to achieve:
- Let user upload file to my server
- Process image (resize etc.)
- Move processed image to my S3 bucket with a specific dynamically generated name, eg. 123876542234.jpg
- Get out the address of the publicly accessible file in my S3 bucket
I have no experience with using S3 but have a strong grasp of PHP. I tried a few tutorials but none of them worked. Any help would be greatly appreciated.
回答1:
IF you download the SDK http://aws.amazon.com/sdkforphp/ they provide a few examples, and one of them is all about S3. It includes how to upload files to S3 using PHP.
回答2:
Make sure you get the newer version 2. It has a faster and more reliable HTTP layer, and uses modern concepts such as Iterators and Observers.
Here's some S3-specific documentation. https://github.com/aws/aws-sdk-php/blob/master/docs/service-s3.rst. Here's all of the other documentation. http://aws.amazon.com/documentation/sdkforphp2/

With a strong grasp of PHP, I'd go straight to the AWS PHP SDK, which contains all the documentation you need to send a given file to S3 using the SDK's API: http://aws.amazon.com/sdkforphp/

For the upload with S3, take a look at this similar topic File upload to Amazon S3 from PHP
and this posts

Amazon doesn't charge you the bandwidth used for upload, but you may be wasting server processing time and your client's bandwidth.
I suggest you to use plupload, it is free and does all the image manipulation on the client side if you want to.
