how to post json data by using asihttprequest

I intend to post json data :

NSString *newJSON = [theDictionary JSONRepresentation];

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:ADDRESS,action]];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request appendPostData:[newJSON dataUsingEncoding:NSUTF8StringEncoding]];

[request startSynchronous];
NSString *responseString = [request responseString];

NSMutableDictionary* responseDict = [responseString JSONValue];
NSLog(@"responseString = %@",responseString);

does the code work?did I miss some code? I read the asihttprequest tutorial,and find it always post data with asiformdatarequest,what's the difference between asihttprequest and asiformdatarequest,if I just want to post json data,what should I do?thank you in advance.

UPDATE:yes,it works,but don't work well,I use some tool test the data,and receive some extra data:

POST / HTTP/1.1
Host: 192.168.0.113
User-Agent: Ushi.com/1.0 CFNetwork/548.1.4 Darwin/11.3.0
Content-Length: 58

You can post text data in json format like this

ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];

[request setRequestMethod:@"POST"];
[request addRequestHeader:@"Accept" value:@"application/json"];
[request addRequestHeader:@"content-type" value:@"application/x-www-form-urlencoded"];
[request addRequestHeader:@"User-Agent" value:@"iPad"];

API itself sets user-agent although you can set it yourself too

request.allowCompressedResponse = NO;
request.useCookiePersistence = NO;
request.shouldCompressRequestBody = NO;
[request setPostBody:[NSMutableData dataWithData:[jsonRequest  dataUsingEncoding:NSUTF8StringEncoding]]];
[request startSynchronous];
