Question

I need to post an NSString into a file on my website. I’ve created a file at http://www.mysite.herokuapp.com/newFile.php and need to post data into newFile.php.

I found this Send String to webserver in iOS? earlier, which I thought was perfect, but soon realized was from 2009/2010 and the code wasn’t working. After fiddling with it for a bit, I got the code below, but it doesn’t work.

So there are two parts to this:

First, should I even be posting into a .php file in the first place? Would .txt be easier?

Second, how do I do this on the website end and the iOS end?

Here is the code I’ve put together in iOS:

// Post data onto external server
             NSString *post = @"IsThisWorking?";
             NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

             NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

             NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
             [request setURL:[NSURL URLWithString:@"https://mysite.herokuapp.com/getLikes.php"]];
             [request setHTTPMethod:@"POST"];
             [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
             [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
             [request setHTTPBody:postData];

Answer 1

you have to handle this on your server.

the method that receives the NSString – which in your example getLikes.php – should save the string to a file on the server.
