My project goal is to upload photos to Tumblr using the Tumblr API found here:
http://www.tumblr.com/docs/api#api_write I can upload general HTML content no problem but when I attempt to upload a photo I get stumped. The API docs say: Normal POST method, in which the file's entire binary contents are URL-encoded like any other POST variable. Maximum size: • 5 MB for videos • 5 MB for photos • 5 MB for audio So I'm trying to get the binary contents of the image according to the API. In my view controller class, I have the following code: NSData *imageData = [image TIFFRepresentation]; NSBitmapImageRep * bitmap; bitmap = [NSBitmapImageRep imageRepWithData:imageData]; NSData *pngData = [bitmap representationUsingType:NSPNGFileType properties:nil]; The pngData is sent to the Tumblr post class where I try to upload it. postType = @"photo"; NSData *imageData = [dataToPost objectForKey:@"image"]; //Comes from view controller pngData variable request_body = [NSString stringWithFormat:@"email=%@&password=%@&type=%@&data=%@", [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [password stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [postType stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [[NSString alloc] initWithData:imageData encoding:NSUTF8StringEncoding]]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.tumblr.com/api/write";]]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[request_body dataUsingEncoding:NSUTF8StringEncoding]]; NSURLConnection * theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self]; The problem is that I can't figure out how to upload the data. I have tried a number of ways but I usually get a Server Response Code 403 - Bad Request. To the best of my knowledge, image data won't convert to NSUTF8StringEncoding-- but how can I fit the data in to the HTTPBody for Tumblr servers to accept?
