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:
https://docs.google.com/feeds/download/presentations/Export?docId=filedid&exportFormat=pptx
But in the 302 code, I have this location:
https://docs.google.com/feeds/download/presentations/Export?exportFormat=pptx&id=fileid
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.

I need to download an archived google group.
Following link is one of the messages of that group for example.

The problem is, what i see in the browser does not appear in the downloaded webpage.
With my very limited knowledge, It seems to me like the reason behind it is this content is dynamically created by java-script. Or else, these downloaded files are with so called 'mbox' extension which is encrypted ?
What I've tried so far
First trys
Simple download
wget https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
With mirror
wget --mirror https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
Assuming its encrypted
With cookies.
wget --load-cookies=cookies.txt https://groups.google.com/d/topic/sci.aeronautics/ViFtpXfVm7M
Got thunderbird to setup my gmail and opening. did not open correctly
Assuming the content was javascript generated
Downloaded using phantomJS
https://askubuntu.com/questions/411540/how-to-get-wget-to-download-exact-same-web-page-html-as-browser
Downloaded using phantomJS with a different script

Used scripts available from Github

But none did not work so far.
Can anyone please shed some light on how to download this page with its message as a readable html or txt file ?

You could use https://groups.google.com/forum/feed/sci.aeronautics/msgs/atom.xml?num=100 to get some of the posts - but it only gets roughly half the posts in this case.
And it has all the messages from all topics together.
View it in Firefox or Classic Opera to see directly in a more human-readable form.
But since you say you already got a file in standard mbox format, what exactly is wrong with it - did you attempt to import it into a locally installed email or newsclient ? (like Thunderbird)
I am trying to use Blueimp jQuery File Upload and it works great with small files. If try to upload anything greater than 50mb it fails and I get an error 'Empty file upload result'.
I have seen lots of responses to questions from people getting the same error but they seem to get it despite the file uploading correctly or the code corrections suggested don't seem to apply to the code that is now supplied with the plugin.
The FAQ suggests that there is a server side restriction on file size but I have asked my host to increase it to 1GB and they have confirmed they have done this. I do not have permission to overwrite the php.ini as suggested in the FAQ, I just get a server error.
Has anyone else had this problem and if so how was it resolved?
I am using PHP.
I am currently trying to download a small binary file from the web, in order to upload that to another website, both using the API.
Previous versions seemed to have the "file" API module for such purposes, but I can't see anything similar as of the latest (1.14).
The file to be downloaded would be saved in some form of cache (browser cache, preferably), its path stored somewhere, to be then uploaded to another URL via POST.
How would I go about it, when the process should happen completely in the background?
I checked out the how to download a file page, but can't figure out where to download.
Is there a variable URI for the "Downloads" directory, and does a regular Add-On has write privileges in it?.
This is important, because the add-on must be able to function properly on various platforms.
You can use the pref, browser.download.lastDir, which should work for windows/mac as it will be saved in the OS format. However the pref may not always be set if the person has never downloaded anything before. In that case you'll have to build the directory yourself.
var dir = require("sdk/preferences/service").get('browser.download.lastDir');
To build the directory yourself you're going to have to go a little deeper. Check this article on MDN about File I/O which has examples. The DfltDwnld key should give you the directory you want.
Your add-on will have write permissions to everything Firefox has write permission to.
I've been trying to figure out how to download multiple files in a row based on the SimpleFTPSample provided by apple. Basically, I'm filtering what the user can see when they browse an ftp server, but when they select a certain file type, I want it to automatically check for another file of the same name with a different extension and if it exists, download it as well. I can't seem to get this second file to download no matter what I do. It seems strange because if I select two files in a row in my tableview, it downloads both of them just fine. Any ideas?
Edit:
It's just the SimpleFTPSample from apple.developer.com, all I did was create additional NSInputStream and NSOutputStream objects and I created a new _startReceiveFile method that gets called from _startReceive if I'm downloading a file instead of getting a directory listing. _startReceiveFile is the same code for _startReceive in the file download code for the sample project, except if the file to download has a certain extension, it also downloads an additional file with the additional stream objects. Let me know if I need to clarify more or try to put together a clear example.
Well, since there were no takers, I'll just post my solution here. I've abandoned trying to download two files at once. Instead, I just keep the ftp browsing window open and only handle the opening of the file once both files have been downloaded (user has clicked on each one separately). It's not what I wanted, but it will work, at least until I can figure out how to get two files with one request.
When i send a .txt file via ftp on the simulator it works fine. but when i send it from the device, the .txt file gets send, put not the contents of it.
Can anyone help?
You asked a similar question the other day (and didn't mark an answer.)
How are you trying to upload the file via FTP? Please show us some code.
As I said in my answer to your other question, an easy way to upload a txt file via ftp would be to use some pre-canned FTP library. This one seems to be good, and they have examples on their web page of how to upload files with just a few lines of code:
