Recently I’ve integrated Google Drive with my iOS application. Everything works fine but .ppt files. Normally if a file is a Drive file I use downloadURL to download it. If the file belongs to Google Docs I use one of the exportLinks (exactly the same as Alain described it here).
However all .ppt files (with "mimeType": "application/vnd.google-apps.presentation") which come from Google Docs are corrupted after being downloaded (I use an export link with exportFormat=pptx). The same file downloaded via web browser works fine.
I use ASIHTTPRequest lib for downloading files (which also can be the reason of corrupted .ppt?).
Any ideas why only ppt files cause problems?
I can already tell you that the lib you’re using isn’t the cause:I’m not using it but I’ve the same problem: it seems that there the code received isn’t 200 (if ($httpRequest->getResponseHttpCode() == 200)) as it shows me a specific error message I’ve asked to return in case of. Also, when I’m trying to download a presentation in PDF or txt, it shows the same error.
It’s not really an answer but I’m trying to understand also why only presentations are causing problems.
EDIT: the code received is 302. If it can help…
EDIT 2: After trying, I noticed that the first parameter is the file id and the second the export format:
But in the 302 code, I have this location:
Not only the two parameters aren’t in the same order but the name is id and not docid
When I take this URL, put it as the export link and then try to copy the file, it’s working. I get a 200 response and the inside of the file.
I hope it helps.
