POST request using AFNetworking 3.0 in xcode 8 (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

What is this?:`req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"email"] longValue];` — Ronak Chaniyara, Jan 09 '17 at 05:07

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];


         }];
    }

[self.activityIndicator stopAnimating]; Does not found on object of type view controller – AlotJai Jan 10 '17 at 07:57
delete that line and check @AlotJai – Suraj Sukale Jan 10 '17 at 07:59
it says that "NSLocalizedDescription=Request failed: unacceptable content-type: text/html}" – AlotJai Jan 10 '17 at 08:05
@AlotJai please add 'manager.requestSerializer = [AFHTTPRequestSerializer serializer];' – Suraj Sukale Jan 10 '17 at 08:44
@AlotJai please check Output of sent parameter to server . is it in right format? right format means in that format in which your server wants.. plz chk it once and add above line in answer. – Suraj Sukale Jan 10 '17 at 08:49

Yes @AlotJai it works for me.. Plz check:- 1} the output of NSLog(@"Sent parameter to server 2 : %@",params); is right? 2}You should add App transport security in your info.plist. – Suraj Sukale Jan 10 '17 at 09:22
yup . already add NSAppTransportSecurity . I'm not sure why it didn't work . it build successfully – AlotJai Jan 10 '17 at 09:28

Nope . . it build successfully . But it has an error when i click on button to request the data . . – AlotJai Jan 11 '17 at 08:49
Please check at your server side, that in which format he want data, and what are you going to send server. – Suraj Sukale Jan 11 '17 at 09:24
