I want to do a HTTP post, updating some information to the server

The URL might be “http://www.aaa.com/aaa.aspx?name=John&pw=123&age=25”

And I think this method should work:

NSURL* url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSData* returnData = [NSData initWithContentsOfURL: url];
[NSString* strRet = [[NSString alloc] initWithData:data encoding:NSUTF8String];

So how could know the update is sucessful? What would be in the NSData returned?

@”200″ or some other string returned by the server, such as @”YES”?

Thanks

    I think your request would end up being a GET request. And the data returned would be whatever data the web site returns for that URL, not the http headers. I recommend using the excellent ASIHTTPRequest library: http://allseeing-i.com/ASIHTTPRequest/ for communicating with web sites, determining POST/GET mode, etc.
