AFNetworking Post Request

Question

I'm a newbie in obj-c and have been using asihttp for some of my projects. When doing a post request in asihttp its done this way.

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

How would go about doing this is AFNetworking with a code example ?
I already got the get Json getrequest working in AFNetworking but this post request is giving me some problems. Thanks for help in advance.

Answer 1

It's first worth adding (as this answer is still popular 6 years after I initially wrote it...) that the first thing you should consider is whether you should even use AFNetworking. NSURLSession was added in iOS 7 and means you don't need to use AFNetworking in many cases - and one less third party library is always a good thing.

For 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);
}];

For AFNetworking 2.0 (and also using the new NSDictionary syntax):

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);
}];

If you are stuck using AFNetworking 1.0, you need to do it this way:

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 2

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                       height, @"user[height]",
                       weight, @"user[weight]",
                       nil];

AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:
                                             [NSURL URLWithString:@"http://localhost:8080/"]];

[client postPath:@"/mypage.php" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
     NSString *text = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
     NSLog(@"Response: %@", text);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"%@", [error localizedDescription]);
}];

Answer 3

Here is a simple AFNetworking POST I'm using. To get up and running after reading the AFNetworking doc, wkiki, ref, etc, I learned a lot by following http://nsscreencast.com/episodes/6-afnetworking and understanding the associated code sample on 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 4

    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);

    }];

Hope this works.

For AFNetworking 4

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

Answer 6

Here an example with 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)")
}

 {

     NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];

     NSLog(@"Response DICT:%@",response);

     if ([[[[response objectForKey:@"response"] objectAtIndex:0] objectForKey:@"status"] isEqualToString:@"true"])

         for (NSMutableDictionary *dicAll in [[[response objectForKey:@"response"]objectAtIndex:0]objectForKey:@"plans"])
         {
             [yourNsmutableArray addObject:[dicAll mutableCopy]];
         }

     [SVProgressHUD dismiss];

 } failure:^(NSURLSessionDataTask  *_Nullable task, NSError  *_Nonnull error)
 {
     NSLog(@"RESPONSE STRING:%@",task.response);
     NSLog(@"error userInfo:%@",error.userInfo);

     NSString *errResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
     NSLog(@"URLString :--->>   %@ Error********* %@",URLString,errResponse);

     [SVProgressHUD dismiss];

 }];

Answer 8

For AFNetworking 3.0 and Swift. Maybe we can use like this:

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)
}

Hope this will help other find answer like me!

Answer 9

For AFNetworking 3.0 (iOS9 or 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];

and Add

-(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 15

Using AFNetworking 3.0, you should write:

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

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

AFHTTPSessionManager * manager = [AFHTTPSessionManager manager];


[manager POST:url.absoluteString parameters:dictParameters success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"PLIST: %@", responseObject);
   
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@", error);
    
}];
