Posting JSON Data Using Afnetworking 2.0

Posting JSON data using AFNetworking 2.0

after searching docs and trying out some codes I got following as an example

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];


NSDictionary *params = @ {@"user" :txtUserName, @"pwd" :txtPwd };


[manager POST:URL_SIGNIN parameters:params
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
    NSLog(@"JSON: %@", responseObject);
}
failure:
 ^(AFHTTPRequestOperation *operation, NSError *error) {
     NSLog(@"Error: %@", error);
 }];

Also don't forget to set response header type in the server script as Application/json.

How to POST data using AFNetworking 2.0?

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).

send JSON object in POST request AFNetworking , iOS

@interface AFJSONRequestSerializer : AFHTTPRequestSerializer

AFJSONRequestSerializeris a subclass ofAFHTTPRequestSerializerthat encodes parameters as JSON using NSJSONSerialization.

add this AFJSONRequestSerializer is used for send JSON not a Raw Data add this and try once

    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];

e.g

NSString *string = [NSString stringWithFormat:@"%@?post_user_info",BaseURLString];
NSString *escapedPath = [string stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];

 /**************  karthik Code added  ******************/
 AFHTTPSessionManager* manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
 manager.responseSerializer = [AFHTTPResponseSerializer serializer];
 manager.requestSerializer = [AFJSONRequestSerializer serializer];
      /**************  karthik Code added  ******************/

    NSDictionary *params = @{@"1": @"hello world",
                             @"2": @"my@you.com",
                             @"3": @"newworldorder"};
[manager POST:escapedPath parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject)
     {
         NSLog(@"%@",responseObject);
          NSError *error = nil;
        NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];
           NSLog(@"json == %@", json);

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

Update Params

NSDictionary *params = @{@"1": @"hello world",
                         @"2": @"my@you.com",
                         @"3": @"newworldorder"};
 NSMutableDictionary *modify = [NSMutableDictionary new];
[modify  setObject:params forKey:@"input_values"];

you get output of

AFNetworking Send JSON as a parameter for POST request

try this

directly pass loginDict in your call and check

manager.requestSerializer = [AFJSONRequestSerializer serializer];
/*
[manager.requestSerializer setTimeoutInterval:20];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
 manager.responseSerializer = [AFJSONResponseSerializer serializer];
 manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
 */
[manager POST:baseUrlLogin parameters: loginDict
     success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

AFNetworking 2.0 post not working well

You returned JSON data as a response, but your assumption that you set Content-Type is incorrect. Create a response instance with the mimetype set to 'application/json'.

from flask import request, json

@app.route('/test', methods=['POST'])
def test():
    data = json.dumps(request.get_json())
    resp = app.response_class(data, mimetype='application/json')
    return resp
