How to pass parameter in php webservice? - iphone

Question

I am working in an app in which i need to pass the json object in that parameter of the request string, now I am stuck here and have no idea how to do this.
SBJSON *json = [SBJSON new];
json.humanReadable = YES;
responseData = [NSMutableData data] ;
NSString *service = #"http://localhost.abc.com/index.php?p=api/user/register";
NSString *requestString = [NSString stringWithFormat:#"{\"Name\":\"%#\",\"Email\":\"%#\",\"Password\":\"%#\",\"PasswordMatch\":\"%#\",\"TermsOfUSe\":\"1\"}",txtusername.text,txtemail.text,txtpassword.text,txtretypepassword.text];
NSData *requestData = [NSData dataWithBytes: [requestString UTF8String] length: [requestString length]];
NSString *urlLoc=#"";
urlLoc = [urlLoc stringByAppendingString:service];
NSLog(#"URL:- %#",urlLoc);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:
[NSURL URLWithString: urlLoc]];
NSString *postLength = [NSString stringWithFormat:#"%d", [requestData length]];
[request setHTTPMethod: #"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:requestData];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
NSLog(#"%#",request);

SBJSON *json = [SBJSON new];
json.humanReadable = YES;
responseData = [NSMutableData data] ;
NSString *service = #"http://localhost.abc.com/index.php?p=api/user/register";
NSString *requestString = [NSString stringWithFormat:#"{\"Name\":\"%#\",\"Email\":\"%#\",\"Password\":\"%#\",\"PasswordMatch\":\"%#\",\"TermsOfUSe\":\"1\"}",txtusername.text,txtemail.text,txtpassword.text,txtretypepassword.text];
NSData *requestData = [NSData dataWithBytes: [requestString UTF8String] length: [requestString length]];
NSString *urlLoc=#"";
urlLoc = [urlLoc stringByAppendingString:service];
NSLog(#"URL:- %#",urlLoc);
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:
[NSURL URLWithString: urlLoc]];
NSString *postLength = [NSString stringWithFormat:#"%d", [requestData length]];
[request setHTTPMethod: #"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:requestData];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
NSLog(#"%#",request);
Delegate method of Connection
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
[responseData setLength:0];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
//**check here for responseData & also data**
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
NSLog([NSString stringWithFormat:#"Connection failed: %#", [error description]]);
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[connection release];
//do something with the json that comes back ... (the fun part)
}

GET Method: In this method you can append the request data behind the web- service.As you doing now by line [request setHTTPMethod: #"POST"];.
POST Method: In this method, you can't append the requested data. But pass the dictionary as a parameter. Like below:
NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:#"StoreNickName"],
[[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:#"user_question"], nil];
NSArray *keys = [NSArray arrayWithObjects:#"nick_name", #"UDID", #"user_question", nil];
NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:#"question"];
NSString *jsonRequest = [jsonDict JSONRepresentation];
NSLog(#"jsonRequest is %#", jsonRequest);
NSURL *url = [NSURL URLWithString:#"https://xxxxxxx.com/questions"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
