Sending POST data from iphone over SSL HTTPS

Question

Hai all,

In my iphone project i need to pass the user name and password to a web server,previously i pass data using GET method and used the url with GET format (eg: localhost:8888/login?userName=admin&password=password ) but now i need to sent this as a POST data,

can any one help me to find what wrong in this code below ?

code i tried ..

NSString *post =[NSString stringWithFormat:@"userName=%@&password=%@",userName.text,password.text];

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

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

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"https://localhost:443/SSLLogin/login.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(data);

I finally got a way to send data over a secure connection from the iPhone:

NSString *post =[[NSString alloc] initWithFormat:@"userName=%@&password=%@",userName.text,password.text];
NSURL *url=[NSURL URLWithString:@"https://localhost:443/SSLLogin/Login.php"];

NSLog(post);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

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

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

/* when we user https, we need to allow any HTTPS cerificates, so add the one line code,to tell teh NSURLRequest to accept any https certificate, i'm not sure about the security aspects
*/

[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];

NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
NSLog(@"%@",data);

to avoid a warning message please add

---

@interface NSURLRequest (DummyInterface)
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString*)host;
+ (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString*)host;
@end
