[google-appengine] Re: upload image into google app engine

[hitesh jain]

I forgot to mention, I am looking for free solution , Google cloud storage 
is paid one from single byte storage. What if I use deprecated File API to 
deal with blob store.

Generally what you'd want to do is retrieve the image via the URL Fetch
service, then write it into Google Cloud Storage:
https://developers.google.com/appengine/docs/java/storage#google_cloud_storage

>From there, if you need the file, you can serve it directly from Cloud
Storage or pipe it through App Engine for handling.

The createUploadUrl route is for uploading files themselves, while above
you stated you were passing image URLs. If you want to upload the image
file (not the URL) then yes, use blobstore's createuploadurl form.

Can you try uploading an empty file to both your development environment
and production App Engine, and seeing what the MD5 hash for each comes out
to be?

[husayt]

Is that it?

What kind of release is this with no single fix/feature ?

[Alexis]

You speak about the whole "Performance Settings" section, but I bet that 
part of it will remain, like settings for "memcache service", and "page 
speed service".
Can you give more details just to make sure?

[google-appengine] How is MD5 hash of a blobstore blob encoded?

[Stephan Hartmann]

Hi together,
 
On the development server BlobInfo.getMd5Hash() returns a String (why not binary array?) that seems to be the hex endoded hash value. I can proof this true with hashing the file locally.
However on Appengine getMd5Hash() returns something different.

It seems to be Base64 encoded, but decoding it with Base64 does not match with what I get locally.

Maybe it uses a different hashing algorithm, too?

Which encoding is used and why is it not consistent on development and production?


 
Any help appreciated.
 
Best regards,
Stephan

[google-appengine] upload image into google app engine

[hitesh jain]

Hi,

I am making an restful call to my application which is deployed in google 
app engine. I pass in the image url to the http request. I want to fetch 
the image content from the URL and store the byte data into appengine. To 
fetch the image data I can use 

URLFetchService. 

To store the image data which can be more than 1 mb what is the best way to do 
that? In this datastore entity I think I can 
store only 1MB byte array.
Once image is stored then I want to get the url of that image so that it can be 
accessed later on anytime.

I have seen google blob store service but that expects HttpRequest as input 
parameter and I will have to use the 
httpclient api to create a POST request and submit to the upload url as 
generated blobstoreService.createUploadUrl("/upload")

Is there any other better way to do this?
