AFNetworking-带有JSON参数的POST方法：var = {JSON}

Question

I'm using a webservice that accepts POST method like this

KEY d ; VALUE {JSON REQUEST}

for example (login):

d={ "action": [ "login" ], "request_data": { "login": { "user": "user", "password": "password" } } }

If I use AFHTTPClient the server doesn't find any "d" parameter. I've tried to create dictionaries with all parameters, serialize via NSJSONSERIALIZE and then wrap everything in a NSMutabliDictionary *parmas with key-value @"d", params to pass to [httpClient postPath[....] ] but with no success. How can I do?

Answer 1

NSString *jsonString  = @"YourStringFromServer";
NSDictionary *temDic = [jsonString JSONValue]; // convert string Value to JSON and add it to Dictionary.
NSlog(@"%@",temDic);// set specific key for specific value.

Answer 2

It's looking for a JSON string. I'm having a bit of trouble understanding the last couple of sentences in your question (you're not describing the steps very clearly) but basically:

//Create your params
NSDictionary *parametersDictionary = [NSDictionary dictionaryWithObjectsAndKeys:
                                                                    yourData, @"action",
                                                                    someMoreData, @"request_data", nil];

NSString *parametersJSONString = [parametersDictionary JSONString];

NSDictionary *parametersToSend = [NSDictionary dictionaryWithObject:parametersJSONString forKey:@"d"];

And you should be good to go. Note that JSONString requires JSONKit. Also, debug/log parametersToSend before sending to make sure you've got the correct data and that the problem doesn't lie elsewhere.
