IPhone sends Json Array via POST

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 using the JSON library , but it was kind of silly to use it. I even tried to create a POST-String 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]];
....

Could you help me? For me, a literal POST line would be enough :)

So this may or may not be the question you ask, but the JSON string is not formed correctly. An array of "tasks" in JSON format will look like this:

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

PHP, , , , :

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]];
...

:

-(void)imageFactory:(NSDictionary*)postJSON
{
    // Convert the JSON string to Data to be sent.
    NSData* postData = [[postJSON JSONRepresentation] dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSMutableURLRequest* request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:[URLManager imageFactory]]];
    [request setHTTPMethod:@"POST"];
    [request setValue:[NSString stringWithFormat:@"%d", [postData length]] forHTTPHeaderField:@"Content-Length"];
    // IMPORTANT MAKE SURE YOU ADD THIS LINE SO THE SERVER KNOWS WHAT ITS GETTING
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    // Add some nice handlers so you know what you got from the server
    NSURLResponse* response;
    NSHTTPURLResponse* httpResponse;
    NSError* error;
    NSData* responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    NSString* stringResponse = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];

    httpResponse = (NSHTTPURLResponse*) response;
    int statuscode = [httpResponse statusCode];

    if (statuscode == 200)
    {
        log4Debug(@"ImageFactory Response Successful, Retrieving image");
        // Handle the response here if needed
    }
    else
    {
        log4Error(@"ImageFactory Response Failed: %@", stringResponse);
        // Show some form of alert here if needed
    }
    // release all objects saved to memory
    [request release];
    request = nil;
    [stringResponse release];
    stringResponse = nil;
}

My json - , : { "user": 1337, "title": "Some title", "itemKeys": [1,1,1,1,1]}

I believe the problem is not with the methods, but with the string you are trying to publish. Try the following:

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

In other words: experiment with quotes.

What JSON library are you using?
