Re: how to download an image

[Matt Maier via use-livecode]

Just following up for posterity.

The livecode team figured out that setting the httpheaders to empty solved
the problem, or at least part of it.
I was setting them to connect to the API that sends the link for the image.
Now setting them to empty before trying to download the image partly works.

It works for "put url"; the image file shows up and isn't corrupted.
It hasn't worked for libURLdownloadToFile; the image file doesn't show up.

I dunno. Here's what I just did and it loaded the image with no 
problems. All 97,183 bytes worth. Do you have write permission to the 
folder you're downloading to?


on mouseUp
   local tImgUrl
   local tImgName
   local tNewFile
   constant tNewFolder="/home/mwieder/Desktop"

   put 
"//s3.amazonaws.com/appforest_uf/f1496548544475x140387106221169240/grilled_cheese_on_plate.jpg" 
into tImgUrl


   put "https:" & tImgUrl into tImgUrl
   set itemdelimiter to "/"
   put item -1 of tImgUrl into tImgName
   set itemdelimiter to comma
   put tNewFolder & "/" & tImgName into tNewFile
   libURLDownloadToFile tImgUrl,tNewFile, "finished"
end mouseUp

on finished
   answer "All Done"
end finished

I've only tried it in the IDE so far.

Is this happening in a standalone or the IDE? A standalone would need
revsecurity.dll for https.

Re: how to download an image

[Matt Maier via use-livecode]

Yeah, I've got a list of URLs like the one in the first message
//s3.amazonaws.com/appforest_uf/f1496548544475x140387106221169
240/grilled_cheese_on_plate.jpg

I'm trying to download the images from AWS to a folder.

Previously I couldn't get "put URL into binfile" to work (0kb files) so I
tried downloading the base64 encoded image data instead. That required
using get/post, which is blocking. Blocking is bad.

So I tried getting the URL instead so I can use libURLDownloadToFile
instead.

I'm getting the same 0kb file problem.

Multiple unknowns here.
First of all, you're conflating 'post' and 'downloading' which is muchly 
confusing.


I assume that tImgUrl starts with "//" at the start of this code. 
Otherwise you'll need to add it after the "https:" prefix.


And don't you want a callback message to make it asynchronous?
And remember to check the URLStatus in the callback handler.

I got bubble.is to send the base64 encoded image data instead of a link. So
just putting the base64decoded data into URL is working.

Re: how to download an image

Scott’s routine worked for me too. It’s worth checking where the spaces and 
returns there are in his test, I had to edit it from the email version. I also 
just tested in the multiline message box. For testing in a button, in LiveCode 
8, you have to declare the variable as well. This was the whole button script:

on mouseUp

local theURL

put 
"http://s3.amazonaws.com/appforest_uf/f1496548544475x140387106221169240/grilled_cheese_on_plate.jpg;
 into theURL

put url theURL into url ("binfile:" & specialFolderPath("desktop") & 
"/DLimage.jpg")

end mouseUp

That gives me a 375b corrupted file. So that's progress.

Remove the first "binfile" usage, so your code reads like this:

put URL tNewImageLink into URL ("binfile:" & tNewFolder & "/" &
tNewImageName)


I used the following to test download to the desktop and it works as
expected:

put 
"http://s3.amazonaws.com/appforest_uf/f1496548544475x140387106221169240/gri
lled_cheese_on_plate.jpg" into theURL
put url theURL into url ("binfile:" & specialFolderPath("desktop") &
"/DLimage.jpg")
