Wanted: Up-to-date example for JSON/POST with basic auth using AFNetworking-2

UPDATE: The JSON portion of the following was found to work for PUT/POST, but NOT for GET/HEAD/DELETE

After some wrangling, and help outside SO, I got something working, which I wanted to leave as a memento. In the end, I was really very impressed with AFNetworking-2. It was so simple, I kept trying to make it harder than it should have been. Given a jsonDict method that returns the json packet to send, I created the following:

- (void) submitAuthenticatedRest_PUT{    // it all starts with a manager    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    // in my case, I'm in prototype mode, I own the network being used currently,    // so I can use a self generated cert key, and the following line allows me to use that    manager.securityPolicy.allowInvalidCertificates = YES;    // Make sure we a JSON serialization policy, not sure what the default is    manager.requestSerializer = [AFJSONRequestSerializer serializer];    // No matter the serializer, they all inherit a battery of header setting APIs    // Here we do Basic Auth, never do this outside of HTTPS    [manager.requestSerializer        setAuthorizationHeaderFieldWithUsername:@"basic_auth_username"        password:@"basic_auth_password"];    // Now we can just PUT it to our target URL (note the https).    // This will return immediately, when the transaction has finished,    // one of either the success or failure blocks will fire    [manager        PUT: @"https://101.202.303.404:5555/rest/path"        parameters: [self jsonDict]        success:^(AFHTTPRequestOperation *operation, id responseObject){            NSLog(@"Submit response data: %@", responseObject);} // success callback block        failure:^(AFHTTPRequestOperation *operation, NSError *error){            NSLog(@"Error: %@", error);} // failure callback block    ];}

3 setup statements, followed by 2 message sends, it really is that easy.

EDIT/ADDED: Here's an example @jsonDict implementation:

- (NSMutableDictionary*) jsonDict{    NSMutableDictionary *result = [[NSMutableDictionary alloc] init];    result[@"serial_id"] = self.serialID;    result[@"latitude"] = [NSNumber numberWithDouble: self.location.latitude];    result[@"longitude"] = [NSNumber numberWithDouble: self.location.longitude];    result[@"name"] = self.name;    if ([self hasPhoto])    {        result[@"photo-jpeg"] = [UIImageJPEGRepresentation(self.photo, 0.5)            base64EncodedStringWithOptions: NSDataBase64Encoding76CharacterLineLength];}return result;

}

It should just return a dictionary with string keys, and simple objects as values (NSNumber, NSString, NSArray (I think), etc). The JSON encoder does the rest for you.
