Hi,
I''ve got a REST API that accepts PUT/POST requests of image data.
(Well, that''s the plan.)
Here are the relevant lines:
My client (using ImageMagick) application reads image data from a file
and then coverts it''s data into a blob:
image = Magick::Image::read(@custom_image.full_filename).first
Obj.image_data = image.to_blob
Obj.save
The ''Obj.save'' initiates a REST request (PUT/POST)that
contains the
binary image data as a member of params
My controller on the REST app can do this:
data = params[:image_data] #=> data is now a String
Here''s how I''m saving the image data to the file system:
File.open(path, "wb") do |f|
f.binmode
f.write data
f.close
end
And data is saved.......but the image is unreadable, (ImageMagick on the
REST app doesn''t recognize the image as a properly formatted jpeg.
My questions are these:
1. What is the best way to send/receive image data to a REST service?
2. Is there anything terribly wrong with the approach I''ve taken?
Thanks for your help,
EB

Elliott, Great, simple solution. How big are the images you''re sending over? Do you notice any performance penalties? I''m thinking of doing the same, though the images I have are fairly small ( < 75k).
