在 xcode 8 (Objective-c) 中使用 AFNetworking 3.0 发布请求？

Question

我正在尝试使用 AFNetworking 3.0 发布请求。

到目前为止，我还没有找到这个问题的确切答案。要么我不明白，要么某些代码已被弃用。

错误是 “dataTaskWithRequest 已弃用”

我有这 两 (2) 个需要发布到网络服务器的文本字段。

1.电子邮件

2。 pw

到目前为止，它没有工作。当前代码如下

#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());

          }];

试试这个代码，我想它会解决你的问题

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);
}];

只需在 AFNetworking 3.0 中按照以下方式进行操作：

        - (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];


         }];
    }
