afnetworking 3.0 Migration: how to POST with headers and HTTP Body

Question

I am trying to make a POST request which has HTTPHeader Fields and a HTTP body to the youtube API.

Previously in version 2.0 of AFNetworking, I used to do it this way which worked:

NSDictionary *parameters = @{@"snippet": @{@"textOriginal":self.commentToPost.text,@"parentId":self.commentReplyingTo.commentId}};

NSString *url = [NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/comments?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters
   options:0
     error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

// And finally, add it to HTTP body and job done.
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];



AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval=[[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"Reply JSON: %@", responseObject);


    }
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);

}];
[operation start];

The migration docs for version 3.0 replaces AFHTTPRequestOperationManager with AFHTTPSessionManager However I can't seem to find a HTTPRequestOperationWithRequest method for the AFHTTPSessionManager.

I tried using the constructingBodyWithBlock but it doesn't work maybe because I am not doing it correctly.

This is what I have so far which doesn't work:

NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body
   options:0
     error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
serializer.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];


[manager POST:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    [formData appendPartWithHeaders:nil body:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

}  progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"Reply JSON: %@", responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);

}];

Answer 1

For HTTPBody with JSON

[sessionManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:error];
    NSString *argString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    return argString;
}];

[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {

    if (completion) {
        completion(responseObject, nil);
    }

} failure:^(NSURLSessionDataTask *task, NSError *error) {

    if (completion) {
        NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
        NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
        completion(responseErrorObject, error);
    }
}];

For HTTPBody with custom String format

[sessionManager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {

    NSString *argString = [self dictionaryToString:parameters];
    return argString;
}];

[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {

    if (completion) {
        completion(responseObject, nil);
    }

} failure:^(NSURLSessionDataTask *task, NSError *error) {

    if (completion) {
        NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
        NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
        completion(responseErrorObject, error);
    }
}];

Accepted answer of #Pranoy C is converted for AFNetworking 3.0

    NSError *writeError = nil;

    NSData* jsonData = [NSJSONSerialization dataWithJSONObject:params options:NSJSONWritingPrettyPrinted error:&writeError];
    NSString* jsonString = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringCacheData  timeoutInterval:120];

    [request setHTTPMethod:@"POST"];
    [request setValue: @"application/json; encoding=utf-8" forHTTPHeaderField:@"Content-Type"];
    [request setValue: @"application/json" forHTTPHeaderField:@"Accept"];
    [request setHTTPBody: [jsonString dataUsingEncoding:NSUTF8StringEncoding]];

    AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    [[manager dataTaskWithRequest:request uploadProgress:nil downloadProgress:nil completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

        if (!error) {
            NSLog(@"Reply JSON: %@", responseObject);

            if ([responseObject isKindOfClass:[NSDictionary class]]) {
                //blah blah

Answer 6

Use common NSObject Class method for Calling Wenservices with AFNetworking 3.0 This is my Duplicate Answer but it was Updated with AFNetworking 3.0 First make NSObject Class Like Webservice.h and Webservice.m

Webservice.h

@interface Webservice : NSObject

+  (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure;

@end

Webservice.m your nsobject.m file is look like this.(add two functions in .m file)

#import "Webservice.h"

#define kDefaultErrorCode 12345

@implementation Webservice

+  (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure {

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];

    [manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if([responseObject isKindOfClass:[NSDictionary class]]) {
            if(success) {
                success(responseObject);
            }
        }
        else {
            NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
            if(success) {
                success(response);
            }
        }

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if(failure) {
            failure(error);
        }

    }];
}

@end

make sure you have to replace your dictionary key with success and message for handling of responce callback function

Use like this call this common method from any viewcontroller.m and any methods from any viewControllers. for temporary i am using viewDidLoad for calling This WS.

 - (void)viewDidLoad {
        [super viewDidLoad];

        NSDictionary *dictParam = @{@"parameter1":@"value1",@"parameter1":@"value2"};

        [Webservice requestPostUrl:@"add your webservice URL here" parameters:dictParam success:^(NSDictionary *responce) {
            //Success
            NSLog(@"responce:%@",responce);
            //do code here
        } failure:^(NSError *error) {
            //error
        }];
    }

add your Parameter, values and webservice URL in above method. you can easily use this NSObjcet Class. for more details please visit AFNetworking 3.0 or my old answear with AFNetworking 2.0.

 -(void)postRequest:(NSString *)urlStr parameters:(NSDictionary *)parametersDictionary completionHandler:(void (^)(NSString*, NSDictionary*))completionBlock{
        NSURL *URL = [NSURL URLWithString:urlStr];

        AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
        manager.responseSerializer = [AFHTTPResponseSerializer serializer];
        [manager POST:URL.absoluteString parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
            NSError* error;
            NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject
                                                                 options:kNilOptions

Answer 9

Another way to call a POST method with AFNetworking 3.0 is:

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"success!");
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error: %@", error);
    }];

Hope it helps!

Answer 10

I was able to figure this out myself.

Here's the solution.

First, you need to create the NSMutableURLRequest from AFJSONRequestSerializer first where you can set the method type to POST.

On this request, you get to setHTTPBody after you have set your HTTPHeaderFields. Make sure to set the body after you have set the Header fields for content-type, or else the api will give a 400 error.

Then on the manager create a dataTaskWithRequest using the above NSMutableURLRequest. Don't forget to resume the dataTask at the very end or else nothing will get sent yet. Here's my solution code, hopefully someone gets to use this successfully:

NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body 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:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" 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:[NSDictionary class]]) {
              //blah blah
        }
    } else {
        NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    }
}] resume];
