File upload with NSURLRequest fails
I'm trying to upload a file with the NSURL* API, but on the server end
the PHP code is unable to decode the $_FILES array. The PHP code
works fine when posted from an HTML form (and from clients on other
platforms).
Traffic sniffed on the wire looks good as far as I can tell, so what
would be the problem? The code in question follows.
NSString *urlString = @"http://server:8080/php/post.php";;
NSURL *url = [NSURL URLWithString:urlString];
NSString *requestMethod = @"POST";
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
[req setHTTPMethod:requestMethod];
NSString *headerFieldName;
NSString *headerFieldValue;
NSString *boundary = @"-1234567890";
headerFieldName = @"Content-Type";
headerFieldValue = [NSString stringWithFormat:@"multipart/form-data;
boundary=%@", boundary];
[req addValue:headerFieldValue forHTTPHeaderField:headerFieldName];
NSString *phone = @"7195554321";
NSDate *currentDate = [NSDate date];
NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init]
autorelease];
[dateFormatter setDateFormat:@"MMddHHmmss"];
NSString *dateString = [dateFormatter stringFromDate:currentDate];
// Will look something like this: form-data; name="file";
filename="7195554321_1_20080311132327_jpg"
headerFieldValue = [NSString stringWithFormat:@"form-data;
name=\"file\"; filename=\"[EMAIL PROTECTED]@_jpg\"", phone, dateString];
NSMutableData *postBody = [NSMutableData data];
// Add boundary
[postBody appendData:[[NSString stringWithFormat:@"[EMAIL PROTECTED]",
boundary]
dataUsingEncoding:NSUTF8StringEncoding]];
// Add form-data with filename
[postBody appendData:[[NSString
stringWithFormat:@"Content-Disposition: [EMAIL PROTECTED]", headerFieldValue]
dataUsingEncoding:NSUTF8StringEncoding]];
// Add content-type
[postBody appendData:[[NSString stringWithString:@"Content-Type:
null\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
// Add image data
[postBody appendData:imageData];
// Add boundary--
[postBody appendData:[[NSString stringWithFormat:@"[EMAIL PROTECTED]",
boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[req setHTTPBody:postBody];
NSHTTPURLResponse *res = nil;
NSError *err = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:req
returningResponse:&res
error:&err];

Re: File upload with NSURLRequest fails
Also, for what it's worth, I can hit the server just fine at the command line with: curl -F "[EMAIL PROTECTED];filename=7195554321_1_20080311132327_jpg" http://server:8080/php/post.php ...yet for some reason the NSURLRequest approach fails. Any/all tips are welcome.

Turns out I was using the wrong number for my multipart boundaries. The actual boundaries need to have two more dashes than the boundary declaration in the content-type header. Once I fixed that, my code worked. -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

You could just use the executable in the .app bundle, though it would lead to some very long command lines. For example you can run TextEdit with "/Applications/TextEdit.app/Contents/MacOS/TextEdit". One approach that some apps take is to have a separate command-line tool which could be installed in /usr/local/bin or some other more normal-seeming place. With this approach you'd probably have a regular drag-install app bundle with a menu item to optionally install the command-line tool. Depending on your architecture the command-line tool could be as simple as a symbolic link to the main bundle's binary. Depending on your requirements, you might consider whether the batch-mode processing would be better implemented as an Automator action. -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

When you call -sendLogs from another class, does the run loop have the chance to run, or does the code block, or busy-wait, or something else that might prevent it from running? You'll need a working run loop for NSURLConnection to successfully post the data and call its delegate methods. Also, is it possible that when -sendLogs is called from another class, it's also called from a separate thread? NSURLConnection's delegate methods are called on the same thread that initiated the connection, and if you've started a different thread, you have to create your own run loop. -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Although the window width differs from Tiger to Leopard, it's not supposed to be a resizable window. If you're going to run on Tiger you'll need to live with the narrower window. I was pretty annoyed when I found out that Leopard's System Preferences wouldn't resize the pref pane view, even if you had designed it to be resizable. But that's the way it is. > Do I have to make my UI narrower and have an obnoxious amount of dead space > around the edges on Leopard? Maybe. You can find out what the current window width is once your preference pane has been loaded into the window. Using something like "[[[self mainView] superview] frame]" would give you the current width, and if desired you could adjust mainView's frame appropriately. This would mean designing to Tiger's pref pane width, and then expanding when running on Leopard. Best to stick with looking up the size instead of the OS version, because who knows what might happen in 10.6? -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Although secondary threads don't automatically get run loops, it's OK to create new run loops in different threads if it's appropriate to your situation. Using -performSelectorOnMainThread: is one way around the problem, but it might make more sense to just give the thread its own run loop. It all depends on your app architecture. -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Oh, they do allow it, despite what the moderators here say. You just have to use the appropriate Apple forum. Apple's support forums have a "developer" section with no shortage of iPhone discussion. Apple hosts it and nobody seems to mind. See <http://discussions.apple.com/category.jspa?categoryID=164> for the forum. It seems kind of silly that iPhone discussion is forbidden here when Apple's apparently not concerned with hosting the discussions elsewhere, but hey, what do I know about it. -- Tom Harrington [EMAIL PROTECTED] AIM: atomicbird1 ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
