Login in this forum with Post method

[billybatigol]

I am trying to understand the way post method works on iphone sdk. But I have some problems with my html and I would like some help. As a reference I use this forum to login with post. I have wrote this code:

the .h file:

#import <UIKit/UIKit.h>
#define kFormURL @"http://www.iphonedevsdk.com/forum/login.php"

@interface RequestTypesViewController : UIViewController {

	UIWebView *webView;
	UITextField *paramName;
	UITextField *paramValue;
	NSMutableData *receivedData;

}  

@property (nonatomic, retain) IBOutlet UIWebView *webView; 
@property (nonatomic, retain) IBOutlet UITextField *paramName; 
@property (nonatomic, retain) IBOutlet UITextField *paramValue;

@property (nonatomic, retain) NSMutableData *receivedData;


- (IBAction)doPostRequest;

@end

The .m file:

#import "RequestTypesViewController.h"

@implementation RequestTypesViewController

@synthesize webView; 
@synthesize paramName; 
@synthesize paramValue;
@synthesize receivedData; 


- (IBAction)doPostRequest { 

NSURL *url = [[NSURL alloc] initWithString:kFormURL]; 
	NSMutableURLRequest *req = [[NSMutableURLRequest alloc]
								initWithURL:url]; 
	[req setHTTPMethod:@"POST"];
	
NSString *paramDataString = [NSString stringWithFormat:@"vb_login_username=%@&vb_login_password=%@", paramName.text, paramValue.text];
	
NSData *paramData = [paramDataString dataUsingEncoding:NSUTF8StringEncoding]; 
	
[req setHTTPBody: paramData];
	 
	 
	
NSURLConnection *theConnection = [[NSURLConnection alloc] 
								initWithRequest:reqdelegate:self];
	 
	 
if (theConnection) { 
	NSMutableData *data = [[NSMutableData alloc] init]; 
	self.receivedData = data; 
	[data release];
} 
else {
	[webView loadHTMLString:@"Unable to make connection!" baseURL:[NSURL 
																   URLWithString:kFormURL]] ;
}
	
	[url release]; 
	[req release]; 
	[paramName resignFirstResponder]; 
	[paramValue resignFirstResponder];
}

- (void)viewDidUnload { 
	self.webView = nil; 
	self.paramName = nil; 
	self.paramValue = nil;
}

- (void)dealloc { 
	[webView release]; 
	[paramName release]; 
	[paramValue release]; 
	[receivedData release]; 
	[super dealloc];
}

//some alerts code

@end

First of all I am not sure about the username and password names. Is this the only problem? Because I have tried everything that I found in the html source code of this forum

NSString *paramDataString = [NSString stringWithFormat:@"vb_login_username=%@&vb_login_password=%@", paramName.text, paramValue.text];

What about the rest of code? Does it seem ok?

no, you need a http requests sniffer to understand what you should do. (in firefox httpfox is ok)

to login in this site, you need

1- load a page where there is the form to login
2- retrieve security token parsing the html, for example (131120627-8c95a8xxxxxxxxxxxxxx7296), search the html to see it.
3- create a http request to this page

http://www.iphonedevsdk.com/forum/login.php?do=login

with the following data in POST (parameter = value) //comment

vb_login_username = username
cookieuser = 1 //or 0, this is not important, enable cookies or not
securitytoken = yourSecurityToken
do = login
vb_login_md5password = yourMd5Password
vb_login_md5password_utf = yourMd5PasswordUsingUtf

and then you are on.


I hope this is not for a bot, there are also too bot here

yes....a little heavy for just http request sniff but really powerfull.

Yes. Its working. Finally!!! I have almost a week that I try to login to a site through my iphone app. Thank you very much guys. Much much appreciated.
Especially dany_dev. I will try implementing on the site that I need to login.

Can anyone tell me the basics of saving the username and password and automatically login. I don't need code. Just the process in steps.

what you mean the basics for save user\pass? NSUserDefault if you want to persist something.....

and to do http request use ASIHTTPRequest or NSURLConnection

I tried in another forum and I made it work. But in the site I have to do it which is a site of a university in greece I can't make it work. It brings a error and I think it is a parameter in the login.
I must put the parameter loginTrue=login and submit1=%C5%DF%F3%EF%E4%EF%F2 but when I do this, I see the error, everything else I do returns just the login site, without actually log me in. I tried passing the submit1 as an NSString but I had the same results.
This site isn't a https site. And I see that it is a ASP.NET and application/x-www-form-urlencoded. Does this have something to do with my problem?

The link of the site is this
just in case.

[dany_dev]

in this case the link where to do the http request is

http://dionysos.teilar.gr/unistudent/login.asp

and the values

userName = yourUsername
pwd = yourPassword
submit1 = Åßóïäïò
loginTrue = login

[billybatigol]

The problem must be in submit1 = Åßóïäïò. This word doesn't seem right. Its not a greek word. Must be a greek word with wrong text encoding. I have to find out asap. Again thank you very much!!!

[dany_dev]

try with that

submit1 = %C5%DF%F3%EF%E4%EF%F2

should work

[billybatigol]

I tried it. I first wrote it as it is and later I tried pass it as a NSString.

NSString *post = [NSString stringWithFormat:@"userName=User&pwd=pass&submit1=%C5%DF%F3%EF%E4%EF%F2&loginTrue=login"];

NSString *submit = @"%C5%DF%F3%EF%E4%EF%F2";
NSString *post = [NSString stringWithFormat:@"userName=user&pwd=pass&submit1=%@&loginTrue=login", submit];

Nothing seems to work. And the submit1 = Åßóïäïò then you chose text encoding greek, when is a greek work meaning "enter". I also tried it with no luck. I send an email to the admin of the site. Hope dies last.
