afnetworking example

Question

Soy un novato en obj-c y he estado utilizando asihttp para algunos de mis proyectos. Al hacer una solicitud posterior en asihttp se hace de esta manera.

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setPostValue:height forKey:@"user[height]"];
    [request setPostValue:weight forKey:@"user[weight]"];
    [request setDelegate:self];
    [request startAsynchronous];

¿Cómo se haría esto con AFNetworking con un ejemplo de código?
Ya obtuve la solicitud get json trabajando en AFNetworking, pero esta solicitud posterior me está dando algunos problemas. Gracias por la ayuda de antemano.

Answer 1

Aquí hay un POST de AFNetworking simple que estoy usando. Para ponerme en funcionamiento después de leer el documento de AFNetworking, wkiki, ref, etc., aprendí mucho al seguir http://nsscreencast.com/episodes/6-afnetworking y comprender la muestra del código asociado en github.

 // Add this to the class you''re working with - (id)init {}
    _netInst = [MyApiClient sharedAFNetworkInstance];

  // build the dictionary that AFNetworkng converts to a json object on the next line
  //  params = {"user":{"email":emailAddress,"password":password}};
  NSDictionary *parameters =[NSDictionary dictionaryWithObjectsAndKeys:
                             userName, @"email", password, @"password", nil];
  NSDictionary *params =[NSDictionary dictionaryWithObjectsAndKeys:
                         parameters, @"user", nil];

   [_netInst postPath: @"users/login.json" parameters:params
      success:^(AFHTTPRequestOperation *operation, id jsonResponse) {
        NSLog (@"SUCCESS");

        // jsonResponse = {"user":{"accessId":1234,"securityKey":"abc123"}};
        _accessId = [jsonResponse valueForKeyPath:@"user.accessid"];
        _securityKey = [jsonResponse valueForKeyPath:@"user.securitykey"];

        return SUCCESS;
      }
      failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"FAILED");

        // handle failure

        return error;
      }
   ];  

Answer 2

Aquí un ejemplo con Swift 3.0

let manager = AFHTTPSessionManager(sessionConfiguration: URLSessionConfiguration.default)
manager.requestSerializer = AFJSONRequestSerializer()
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Content-Type")
manager.requestSerializer.setValue("application/json", forHTTPHeaderField: "Accept")

if authenticated {
    if let user = UserDAO.currentUser() {
        manager.requestSerializer.setValue("Authorization", forHTTPHeaderField: user.headerForAuthentication())
    }
}

manager.post(url, parameters: parameters, progress: nil, success: { (task: URLSessionDataTask, responseObject: Any?) in 
    if var jsonResponse = responseObject as? [String: AnyObject] {
        // here read response
    }
}) { (task: URLSessionDataTask?, error: Error) in
    print("POST fails with error /(error)")
}

Answer 3

Para AFNetworking 3.0 y Swift. Tal vez podamos usar esto:

let configutation = NSURLSessionConfiguration.defaultSessionConfiguration()
manager = AFHTTPSessionManager(sessionConfiguration: configutation)

let urlString = "url"
manager.POST(urlString, parameters: [params here], progress: nil, success: { (dataTask: NSURLSessionDataTask, response: AnyObject?) -> Void in
        print(dataTask)
        print(response)
        }) { (dataTask: NSURLSessionDataTask?, error: NSError) -> Void in
        print(error)
}

Espero que esto ayude a otros a encontrar respuestas como yo.

Answer 4

Para AFNetworking 3.0 ( iOS9 o greter )

 NSString *strURL = @"https://exampleWeb.com/webserviceOBJ";
    NSDictionary *dictParamiters = @{@"user[height]": height,@"user[weight]": weight};

    NSString *aStrParams = [self getFormDataStringWithDictParams:dictParamiters];

    NSData *aData = [aStrParams dataUsingEncoding:NSUTF8StringEncoding];

    NSMutableURLRequest *aRequest = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:strURL]];
    [aRequest setHTTPMethod:@"POST"];
    [aRequest setHTTPBody:aData];

    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
    [aRequest setHTTPBody:aData];

    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:aRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        //
        if (error ==nil) {
            NSString *aStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
            NSLog(@"ResponseString:%@",aStr);
            NSMutableDictionary *aMutDict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
            dispatch_async(dispatch_get_main_queue(), ^{
                    completionBlock(aMutDict);

                NSLog(@"responce:%@",aMutDict)

            });
        }
        else
        {
            dispatch_async(dispatch_get_main_queue(), ^{
                NSLog(@"error:%@",error.locali)
            });
        }
    }];

    [postDataTask resume];

y añadir

-(NSString *)getFormDataStringWithDictParams:(NSDictionary *)aDict
{
    NSMutableString *aMutStr = [[NSMutableString alloc]initWithString:@""];
    for (NSString *aKey in aDict.allKeys) {
        [aMutStr appendFormat:@"%@=%@&",aKey,aDict[aKey]];
    }
    NSString *aStrParam;
    if (aMutStr.length>2) {
        aStrParam = [aMutStr substringWithRange:NSMakeRange(0, aMutStr.length-1)];

    }
    else
        aStrParam = @"";

    return aStrParam;
}

Answer 5

Primero vale la pena agregar (ya que esta respuesta sigue siendo popular 6 años después de que la escribí inicialmente ...) que lo primero que debes considerar es si incluso debes usar AFNetworking. NSURLSession se agregó en iOS 7 y significa que no necesita usar AFNetworking en muchos casos, y una biblioteca de terceros es siempre algo bueno.

Para AFNetworking 3.0:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

Para AFNetworking 2.0 (y también utilizando la nueva sintaxis NSDictionary):

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"user[height]": height,
                         @"user[weight]": weight};
[manager POST:@"https://example.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

Si está atascado usando AFNetworking 1.0, debe hacerlo de esta manera:

NSURL *url = [NSURL URLWithString:@"https://example.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        height, @"user[height]",
                        weight, @"user[weight]",
                        nil];
[httpClient postPath:@"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"Request Successful, response ''%@''", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"[HTTPClient Error]: %@", error.localizedDescription);
}];

Answer 6

Usando AFNetworking 3.0, debe escribir:

NSString *strURL = @"https://exampleWeb.com/webserviceOBJ";
NSURL * urlStr = [NSURL URLWithString:strURL];

NSDictionary *dictParameters = @{@"user[height]": height,@"user[weight]": weight};

AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];


[manager GET:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"PLIST: %@", responseObject);

} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);

}];

Answer 7

para la pantalla de inicio de sesión;

NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
dict = [NSMutableDictionary 

dictionaryWithObjectsAndKeys:_usernametf.text, @"username",_passwordtf.text, @"password", nil];
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];

[manager POST:@"enter your url" parameters:dict progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"%@", responseObject);

}
      failure:^(NSURLSessionTask *operation, NSError *error) {
          NSLog(@"Error: %@", error);
      }];

}

Answer 8

    AFHTTPClient * Client = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://urlname"]];
    NSDictionary * parameters = [[NSMutableDictionary alloc] init];
    parameters = [NSDictionary dictionaryWithObjectsAndKeys:
                 height, @"user[height]",
                        weight, @"user[weight]",
                  nil]; 

    [Client setParameterEncoding:AFJSONParameterEncoding];
    [Client postPath:@"users/login.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"operation hasAcceptableStatusCode: %d", [operation.response statusCode]);

    NSLog(@"response string: %@ ", operation.responseString);

    NSDictionary *jsonResponseDict = [operation.responseString JSONValue];
        if ([[jsonResponseDict objectForKey:@"responseBody"] isKindOfClass:[NSMutableDictionary class]]) {
            NSMutableDictionary *responseBody =  [jsonResponseDict objectForKey:@"responseBody"];
           //get the response here


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        NSLog(@"error: %@", operation.responseString);
        NSLog(@"%d",operation.response.statusCode);

    }];

Espero que esto funcione.
