Question

I’m facing an odd behavior. I use the following code to send an HTTP
request to a server using a POST method

[[RKClient sharedClient] post:[NSString stringWithFormat:@"api"]
                           params:aDict
                         delegate:self];

The dictionary that hold the values is as followed :

NSDictionary *comment = [NSDictionary dictionaryWithObjects:[NSArray
arrayWithObjects:@"wallcomment", [self.wall
valueForKey:@"wallMessageId"], [self.textView text], nil]
                                                        forKeys:
[NSArray arrayWithObjects:@"a01call", @"a01wall_message_id",
@"a01comment", nil]];

When [self.textView text] is filled in with French word with accent
the server receive with wrong encoding : “Test @ vérification
caractères spéciaux”

I do not manipulate the textview text before posting so encoding is also UTF8.

When i check the POST header, the content-type is not having the encoding type. I tried to add it with the following method but it’s not added :

- (void)setValue:(NSString *)value forHTTPHeaderField:(NSString *)header

Any special method or property i haven’t seen in the documentation ?

I’m using the RestKit 0.9.3

Do this:

[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"api" delegate:self block:^(RKObjectLoader *loader) {
    [loader setAdditionalHTTPHeaders:[NSDictionary dictionaryWithObjectsAndKeys:@"application/x-www-form-urlencoded;charset=UTF-8", @"Content-Type", nil]];
}];

Don’t forget to add other headers if you need any.

One additional thing that I noticed while going through RestKit code, RKObjectManager line 222:

loader.method = RKRequestMethodGET;

So don’t be surprised you the method is GET, not POST. If you really need POST (which I think you don’t), then change the method in the block.
