Send files from iphone
-
I need to be able to upload the data from a UIImage to a server via
http POST however I simply cannot find a good example of how to
arrange the headers or how to make this post.
The only data I need to send to the server is the file's name, the
user's name and the data itself and I simply cannot seem to get it to
work. Can any of you offer a helping hand? -
What have you tried? Or at least looked at trying?

I have been trying to write my headers for multipart form data. I'm
then sending the data over a NSStream. If it would be easier however
to compact this somehow into a url request that would work fine too. I
just need to figure out how to get the file to the server.

Check out documentation on NSURLRequest and NSURLConnection.

I also tried this and it fails. The form never gets any post variables
or files:
[self sendText:@"Content-Type: multipart/form-data; boundry=@@##$$-
rew-**&&^%^\n"];
[self sendText:boundry];
[self sendText:[NSString stringWithFormat:@"Content-Length: %i\n
\n",totalSize]];
[self sendText:[NSString stringWithFormat:@"Content-Disposition: form-
data; name=\"%@\"\r\n\r\n",@"fileName"]];
[self sendText:[NSString stringWithFormat:@"%@",name]];
[self sendText:boundry];
[self sendText:[NSString stringWithFormat:@"Content-Disposition: form-
data; name=\"%@\"\r\n\r\n",@"directory"]];
[self sendText:[NSString stringWithFormat:@"%@",dir]];
[self sendText:boundry];
[self sendText:[NSString stringWithFormat:@"Content-Disposition: form-
data; name=\"imagefile\" filename=\"%@\"\r\n",name]];
[self sendText:@"Content-Type: application/octet-stream\r\n\r\n"];
[self sendData:imageData];
[self sendText:boundry];

Ok I have made a tiny bit of progress.
The problem is that the _POST and _FILE arrays are still empty Well...
the _POST array on the server is filled with a mix of the data it
should have scrambled in with jpeg data. I desperately need help I
cannot find the answer for this for some reason. I've been googling
for hours now and the example code doesn't work either.
Below is the sending code:
NSMutableData * sendData= [[NSMutableData alloc]init];
NSMutableData * body= [[NSMutableData alloc]init];
NSString * boundry = @"@@##$$rew**&&^%^";
NSString * name=[path lastPathComponent];
NSString * dir= [path stringByDeletingLastPathComponent];
[body appendData:[[NSString stringWithFormat:@"--%@\r
\n",boundry]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition:
form-data; name=\"%@\"\r\n\r
\n",@"fileName"]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString
stringWithFormat:@"%@",name]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r
\n",boundry]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition:
form-data; name=\"%@\"\r\n\r
\n",@"directory"]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString
stringWithFormat:@"%@",dir]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r
\n",boundry]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition:
form-data; name=\"image_file\" filename=\"%@\"\r\n\r
\n",name]dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n"
dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r
\n",boundry]dataUsingEncoding:NSUTF8StringEncoding]];
int totalSize =[body length];
NSLog(@"Total size: %i",totalSize);
[sendData appendData:[@"Content-Type: multipart/form-data;
boundary=@@##$$rew**&&^%^\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[sendData appendData:[[NSString stringWithFormat:@"Content-Length: %i
\r\n\r\n",totalSize]dataUsingEncoding:NSUTF8StringEncoding]];
[sendData appendData:body];
[self startConnection];
[self sendMainHeadersForPage:@"/image.php"];
[self sendData:sendData]; -
It's the smallest errors that create the greatest frustration. I left
out a semi colon. and misspelled boundary. Which makes me wonder why
the examples I found didnt work.

I don't know if CoreFoundation stuff is available on iPhone but if it is, CFHTTPMessage is an excellent way to do HTTP POST.
Best regards,

I'm not quite sure about whether "Available in Mac OS X version 10.1
and later" means that it's not available in iPhone OS.
But, I assume everything that exists on iPhone OS reference library,
exists on iPhone OS, because that's also the case with
NSURLConnection, which obviously exists on iPhone OS.

CoreFoundation exists on the iPhone. And you can look at cocoadev.org
for a decent HTTP Post example there or look on Google code for a
class that does Flickr uploads through HTTP Post and that works on the
iPhone.
HTTP Post is not hard, but it does expect a very specific way of doing
it.
