How to send login and password to a server using ASIHTTPRequest? - iphone

Question

I'm pretty new to everything that deals with http and stuff like that and i know almost nothing about how http methods work so i need your advice. In my app i have to send login and password to a server and get a response. By now i'm trying to write a method (it's called STUB in English i believe) which will work in a general way without communicating to actual server. Should i use POST method in a manner similar to:
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:some_server_url];
[request addPostValue:passwordString forKey:loginString];
or something else? if first how do i receive the response from the server? Could you please show me few lines of code?

You can pass login details to server using HTTP POST method like this :
-(NSDictionary*)userLogIn:(NSMutableDictionary*)inputDictionary{
SBJSON *parser = [[SBJSON alloc] init];
NSString *convertedString=[NSString stringWithFormat:#"login=%#&password=%#",username, password];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"Give the url here"]];
[request setHTTPBody:[convertedString dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"XXXX" forHTTPHeaderField:#"USER_AGENT"];
[request setHTTPMethod:#"POST"];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSASCIIStringEncoding];
NSDictionary *statuses = [parser objectWithString:json_string error:nil];
[parser release];
[json_string release];
return statuses;
}
This is a sample code and you have to change according to your requirements.
