I'm trying to get a public url that can be accessed anywhere for streaming. I can get the downloadUrl, but doing the same for exportLinks results in null values. The code for this is below, though I don't know what my problem is.

NSError *error;
NSString *exportURLStr;  
GTLDriveFile *file = [driveFiles objectAtIndex:indexPath.row];
exportURLStr = [NSString stringWithFormat:@"%@",file.exportLinks];  
NSURL *url = [NSURL URLWithString:exportURLStr];
NSString *temp1= [NSString stringWithFormat:@"%@",url];

// NSLog of temp1 is Null
// I tried with file.WebContentLink  but getting 404 Error

This is only a snippet of the code, so if I need to show more, just ask.

From google-api-objectivec-client go to DriveSampleWindowController.m,

check the method called - (void)downloadFormatSelected:(NSMenuItem *)menuItem where its shown cleary how to format the exportLinks.

 NSLog(@"%@",[file.exportLinks JSONValueForKey:@"urtitlekey"]);

This is what you wanted.Hope it helps.

A file will either have a downloadUrl or a set of exportLinks. Not both. exportLinks is for converting native Google docs into a PC format (eg Google spreadsheet to .xls).

I think webContentLink may be the property you need to use.

  • Check the headers in the response using Chrome Devtools. I suspect you'll see "content-disposition:attachment;" which instructs the browser to download rather than render the content. afaik there is no way to ask Google to change this header so you might need to proxy the request. – pinoyyid Sep 12 '13 at 16:00
