iPhone sending Json Array via POST

Question

I need to send the following JSON array via POST to our server:

task:{"id":"123","list":"456","done":1,"done_date":1305016383}

I tried with the JSON library, but I was somehow to stupid to use it. I even tried to build up the POST-String by myself, but also failed:

NSString *post = @"task='{id:123,list:456,done:1,done_date:1305016383}'";

NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url 
                                               cachePolicy:NSURLRequestReloadIgnoringCacheData    
                                            timeoutInterval:30];

[request setHTTPMethod:@"POST"];    
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
....

Can you please help me? The json’ed POST string would be even enough for me :)

So this may or may not be the question you are asking, but your JSON string is not formed correctly. An array of "task" in JSON format would look like this:

NSString *post = @"{"task":[{"id":"123","list":"456","done":1,"done_date":1305016383}]}";

I was just wresting with a similar situation posting to a PHP server and I couldn't find any questions about it online, but this is what I would've had to do if I were posting the same data:

NSString *post = @"task[0][id]=123&task[0][list]=456&task[0][done]=1&task[0][done_date]=1305016383&";

NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:url 
                                           cachePolicy:NSURLRequestReloadIgnoringCacheData    
                                        timeoutInterval:30];

[request setHTTPMethod:@"POST"];    
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
...

Good luck!
