Hi All
I am a new bee.
I am trying to create a login page.
Here I accept the userid and password and when the user hits submit button the method loginUser would be executed.
I am trying to connect to a JavaServer in the Backend (running on a Windows m/c).
I am connecting to the server but my application is hanging at the following line:
responseData = [[NSMutableData alloc] init];
How do I capture the response from the server?
I have pasted my whole code below. The servers response would be Valid User or Invalid User.
I have now hard coded the URL now as I dont know how to send the inputs individually. (I can use POST but how to pass the parameters in case I have more than 4 and secure ones like the userId and password?)
Can someone please help me with this?
One more thing is that I couldn't use @try and @catch methods, are there any pre-requisites for this?
Thank you,
Dee
PS: I have got all the code from the net. (Mostly developer.apple.com)
@interface Login : NSObject
{
IBOutlet NSTextField *password;
IBOutlet NSTextField *userId;
NSMutableData *responseData ;
}
- (IBAction)loginUser:(id)sender;
@end
@implementation Login
- (IBAction)loginUser:(id)sender
{
NSString *usrId;
NSString *pwd;
NSLog (@" local variables created");
usrId = [userId stringValue];
pwd = [password stringValue];
//pwd = [self valueForKey:@"password"];
NSLog (@"Data copied to local variables");
NSLog (@"UserID = %@, Password = %@", usrId, pwd);
//@try {
NSURL *myURL = [NSURL URLWithString:@"http://172.19.23.74:8080/DemoApp/DemoServ?userId=dee&password=bee";];
NSLog (@"URL written");
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL]; // cachePolicy:NSURLRequestUserProtocolCachePolicy timeoutInterval:60.0];
NSLog (@"request loaded");
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
NSLog (@"connection established");
if (conn) {
NSLog (@"in the if loop");
responseData = [[NSMutableData alloc] init]; // is this correct since the application hangs here. Here I am trying to capture the servers response.
NSLog (@"response = %@", [responseData mutableBytes]);
}
/*}
@catch(NSException e){
NSLog (@"there has been an error %@", e);
}@finally{
NSLog (@"the program is complete");
}*/
NSLog (@"Finished");
}
