POST request using AFNetworking 3.0 in xcode 8 (Objective-c)? - objective-c

Question

I'm trying to POST request using AFNetworking 3.0.
So far i did not find the exact answer for this issue. Either i don't understand or some of the code is deprecated.
Error is "dataTaskWithRequest is deprecated"
I have this two (2) textfield that need to be post into web server.
1. email
2. pw
So far it didn't work. The current code as below
#import "ViewController.h"
#import "AFNetworking.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize email,pw;
- (IBAction)sendData:(id)sender {
NSString *URLString = #"http://localhost/test.php";
NSDictionary *parameters =#{#"email" : #"pw"};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:#"POST" URLString:URLString parameters:nil error:nil];
req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:#"email"] longValue];
[req setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[req setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(#"Reply JSON: %#", responseObject);
if ([responseObject isKindOfClass:[NSArray class]]) {
NSLog(#"Response == %#",responseObject);
}
} else {
NSLog(#"Error: %#, %#, %#", error, response, responseObject);
}
}]resume];
}
#end

NSString *URLString = #"http://localhost/test.php";
NSDictionary *parameters =#{#"email":#"pass email id" #"pw":#"pass password"};
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.responseSerializer=[AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:#"application/x-www-form-urlencoded"];
[manager POST:URLString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
options:kNilOptions
error:&error];
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:#"Aleksi"
message:[error localizedDescription]
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *actionOk = [UIAlertAction actionWithTitle:#"Ok"
style:UIAlertActionStyleDefault
handler:nil]; //You can use a block here to handle a press on this button
[alertController addAction:actionOk];
NSLog(#"error=%#",error );
CFRunLoopStop(CFRunLoopGetCurrent());
}];

try this code, i guess it will solve your issue
NSString *url = #"http://localhost/test.php";
NSDictionary* parametersDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
email, #"email",
password, #"pw",
nil
];
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[manager.requestSerializer setValue:#"application/x-www-form-urlencoded; charset=UTF-8" forHTTPHeaderField:#"Content-Type"];
//you can change timeout value as per your requirment
[manager.requestSerializer setTimeoutInterval:60.0];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
[manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(#"%#",responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"%#",error);
}];

Simply do like following way in AFNetworking 3.0 :
- (IBAction)sendData:(id)sender {
NSString *Loginurl = [NSString stringWithFormat:Your_URL_is_here];
NSDictionary *params = #{#"user_name":username.text,
#"password":password.text,
};
//here we can see parameters which is sent to server
NSLog(#"Sent parameter to server 2 : %#",params);
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
AFSecurityPolicy* policy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeCertificate];
[policy setValidatesDomainName:NO];
[policy setAllowInvalidCertificates:YES];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json", #"text/json", #"text/javascript",#"text/html", nil];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json",#"text/html",nil];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:#"application/json",#"text/plain",nil];
[manager POST:Loginurl parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
// Here we can see response which is coming from server
NSLog(#"Response from server 2 : %#", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
} failure:^(NSURLSessionTask *operation, NSError *error)
{
// If Error occur, then this is AlertController Appear
NSLog(#"Error: %#", error);
UIAlertController *Erroralert= [UIAlertController
alertControllerWithTitle:#" Network Connection Failed!!"
message:#"Please try again"
preferredStyle:UIAlertControllerStyleAlert];
[self presentViewController:Erroralert animated:YES completion:nil];
UIAlertAction* yesButton = [UIAlertAction
actionWithTitle:#"Ok"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[self resignFirstResponder];
[Erroralert dismissViewControllerAnimated:YES completion:nil];
}];
[Erroralert addAction: yesButton];
}];
}
