How to POST data using AFNetworking 2.0?

I need to send my data by POST, in variable data.

I do it like this:

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = @{@"email" : email, @"password" : pass };
[manager POST:URLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:
 ^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error); }];

and have:

JSON: {
Data = "<null>";
Message = "unexpected end of JSON input";
Result = fail;
}

I know the method

  - (AFHTTPRequestOperation *)POST:(NSString *)URLString
                  parameters:(NSDictionary *)parameters
   constructingBodyWithBlock:(void (^)(id <AFMultipartFormData>))block
                     success:(void (^)(NSURLSessionDataTask *, id))success
                     failure:(void (^)(NSURLSessionDataTask *, NSError *))failure;

But how can I send my dictionary in variable data to the web server?

Does your web service expect the parameters to be formatted as JSON? If so, before you invoke the POST method, you need to tell the manager to use a JSON requestSerializer, i.e. AFJSONRequestSerializer:

manager.requestSerializer = [AFJSONRequestSerializer serializer];

By default, AFNetworking assumes you want to use AFHTTPRequestSerializer (i.e. a request with a Content-Type of application/x-www-form-urlencoded).
