AFNetworking Post Request

/ 02 октября 2011

Я новичок в obj-c и использую asihttp для некоторых моих проектов.При выполнении почтового запроса в asihttp это делается следующим образом.

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

Как это сделать, если AFNetworking с примером кода?
Я уже получил get get Json, работающий в AFNetworking, но этот пост-запрос вызывает у меня некоторые проблемы.Спасибо за помощь заранее.

Прежде всего стоит добавить (так как этот ответ по-прежнему популярен через 6 лет после того, как я его изначально написал ...), первое, что вы должны рассмотреть, стоит ли вообще использовать AFNetworking. NSURLSession был добавлен в iOS 7 и означает, что вам не нужно использовать AFNetworking во многих случаях - и одна менее сторонняя библиотека всегда полезна.

Для 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);
}];

Для AFNetworking 2.0 (а также с использованием нового синтаксиса 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);
}];

Если вы застряли с помощью AFNetworking 1.0, вам нужно сделать это следующим образом: 

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);
}];

Вот простой AFNetworking POST, который я использую.Чтобы приступить к работе после прочтения документа AFNetworking, wkiki, ref и т. Д., Я многому научился, следуя http://nsscreencast.com/episodes/6-afnetworking и понимая связанный с ним пример кода на 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;
      }
   ];

    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);

    }];

Надеюсь, что это работает.

Вот пример с 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)")
}
