Question

In RestKit Version 0.10.x I used

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/special/path" usingBlock:^(RKObjectLoader *loader) {
            loader.objectMapping = aMapping;
            loader.delegate = _delegate;
            loader.method = RKRequestMethodPOST;
            loader.userData = [MobileGatewayReauthentication class];
            loader.params = [anDictionary toJsonRKParam];
        }];

to add a NSDictionary to loader.params to send a collection of parameters as the HTTP body of the request.

---

Since RestKit 0.20.0 the method loadObjectsAtResourcePath has been replaced by the following method, where it is no longer possible to pass a NSDictionary in parameters, which is used as HTTP Body (JSON encoded):

[RKObjectManager.sharedManager getObjectsAtPath:path parameters:params success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
{
    NSLog(@"success");
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    NSLog(@"failure");
}];

When working with [[RKObjectManager sharedManager].HTTPClient (AFNetworking) it works like a charm when setting:

[[RKObjectManager sharedManager].HTTPClient setParameterEncoding:AFJSONParameterEncoding];

[[RKObjectManager sharedManager].HTTPClient postPath:path parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Response: %@", operation.responseString);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@",error.localizedDescription);
}];

But I need the higher-level object mapper.

---

[[RKObjectManager sharedManager].HTTPClient setParameterEncoding:AFJSONParameterEncoding];

has no effect on [RKObjectManager sharedManager] but

[[RKObjectManager sharedManager].HTTPClient setDefaultHeader:@"aHeader" value:@"aValue"];

has. So I assumed that setParameterEncoding works, too.

Is it a bug, is it not yet implemented, or have I missed something?

Thanks a lot.

I really have missed something.

loadObjectsAtResourcePath get’s (for sure) called with RKRequestMethodGET. So the parameters get append to the URL, not to the HTTP body.

To append the parametrs as a JSON HTTP body, you have to use a post method, for example

- (void)postObject:(id)object
              path:(NSString *)path
        parameters:(NSDictionary *)parameters
           success:(void (^)(RKObjectRequestOperation *operation, RKMappingResult *mappingResult))success
           failure:(void (^)(RKObjectRequestOperation *operation, NSError *error))failure;

Excuse the hasty question. I should have seen it before.
