Afnetworking 2 with parameters - ios

Question

i am really new to IOS developments..i just want to get some JSON response from my web service. when i searched about it i found AFnetworking is good for that. so i downloaded it and did a sample application. but i need to pass some parameters to the service . my service takes two parameters [username and password]. my url like this
http://myweb.mobile.com/WebServices/AppointmentService.asmx/GetValidUser
can anyone please give me some code sample how to pass my parameters to this service to get json response ?
i have tried this code.. but it wont take parameters.. some people telling about AFHTTPClient.. but im using AFN 2.0.. there is no class call AFHTTPCLient here .. i'm so conduced here....please help me
NSURL *url = [NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/textsearch/json?query=restuarants+in+sydney&sensor=false&key=AIzaSyDn9a-EvJ875yMxZeINmUP7CwbO9YT1w2s"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
// 2
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// 3
self.googlePlaces = [responseObject objectForKey:#"results"];
[self.tableView reloadData];
// NSLog(#"JSON RESULT %#", responseObject);
self.weather = (NSDictionary *)responseObject;
self.title = #"JSON Retrieved";
[self.tableView reloadData];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
// 4
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error Retrieving Weather"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:#"Ok"
otherButtonTitles:nil];
[alertView show];
}];
// 5
[operation start];
EDIT :
i have sloved my problem using below code segments...
NSDictionary *parameters = [[NSDictionary alloc] initWithObjectsAndKeys:#"47", #"caregiverPersonId", nil];
AFSecurityPolicy *policy = [[AFSecurityPolicy alloc] init];
[policy setAllowInvalidCertificates:YES];
AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager setSecurityPolicy:policy];
operationManager.requestSerializer = [AFJSONRequestSerializer serializer];
operationManager.responseSerializer = [AFJSONResponseSerializer serializer];
[operationManager POST:#"your full url goes here"
parameters:parameters
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", [responseObject description]);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", [error description]);
}
];

Answer 1

Try this
-(void)login
{
NSMutableDictionary *dict=[[NSMutableDictionary alloc]initWithCapacity:3];
[dict setObject:_usernameTextField.text forKey:#"userName"];
[dict setObject:_passwordTextField.text forKey:#"password"];
AFHTTPClient *client=[[AFHTTPClient alloc]initWithBaseURL:[NSURL URLWithString:#""]];
[client registerHTTPOperationClass:[AFJSONRequestOperation class]];
[client setDefaultHeader:#"Accept" value:#"application/json"];
client.parameterEncoding = AFJSONParameterEncoding;
[client postPath:#"GetValidUser" parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *op=(NSDictionary *)responseObject;
NSLog(#"%#",op);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:MESSAGE_EN message:#"Unable to login. Please try again." delegate:self cancelButtonTitle:OK_EN otherButtonTitles:nil, nil];
[alert show];
NSLog(#"error.localizedDescription %#",error.localizedDescription);
}];
}
Note : Please do fill the fields with proper values and try.
dict is the Input postdata

I got this one from somewhere in SO question. See this:
- (IBAction)loginButtonPressed {
NSURL *baseURL = [NSURL URLWithString:#"http://myweb.mobile.com/WebServices/AppointmentService.asmx"];
//build normal NSMutableURLRequest objects
//make sure to setHTTPMethod to "POST".
//from https://github.com/AFNetworking/AFNetworking
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:baseURL];
[httpClient defaultValueForHeader:#"Accept"];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
[usernameTextField text], kUsernameField,
[passwordTextField text], kPasswordField,
nil];
NSMutableURLRequest *request = [httpClient requestWithMethod:#"POST"
path:#"http://myweb.mobile.com/WebServices/AppointmentService.asmx/GetValidUser" parameters:params];
//Add your request object to an AFHTTPRequestOperation
AFHTTPRequestOperation *operation = [[[AFHTTPRequestOperation alloc]
initWithRequest:request] autorelease];
//"Why don't I get JSON / XML / Property List in my HTTP client callbacks?"
//see: https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-FAQ
//mattt's suggestion http://stackoverflow.com/a/9931815/1004227 -
//-still didn't prevent me from receiving plist data
//[httpClient registerHTTPOperationClass:
// [AFPropertyListParameterEncoding class]];
[httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];
[operation setCompletionBlockWithSuccess:
^(AFHTTPRequestOperation *operation,
id responseObject) {
NSString *response = [operation responseString];
NSLog(#"response: [%#]",response);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"error: %#", [operation error]);
}];
//call start on your request operation
[operation start];
[httpClient release];
}
Hope this helps .. :)
EDIT
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:URLString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFormData:[email dataUsingEncoding:NSUTF8StringEncoding]
name:#"email"];
[formData appendPartWithFormData:[pass dataUsingEncoding:NSUTF8StringEncoding]
name:#"password"];
// etc.
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Response: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Use below code
NSDictionary *paramDictionary = [NSDictionary dictionaryWithObjectsAndKeys:#"first_Object",#"first_Key",#"second_Object",#"second_Key" nil];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:#"YOUR_URL_STRING" parameters:paramDictionary success:^(AFHTTPRequestOperation *operation, id responseObject) {Success responce} failure:^(AFHTTPRequestOperation *operation, NSError *error) {failure responce}];
if you want you can set
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.securityPolicy.allowInvalidCertificates = YES;
