Can't post dictionary with array with AFNetworking - ios

Question

Apparently, the server can't understand my dictionary with array.
I wrote this
NSURL *url = [NSURL URLWithString:#"http://"];
self.manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:url];
self.manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
[self.manager setResponseSerializer:responseSerializer];
self.manager.responseSerializer.acceptableContentTypes = [self.manager.responseSerializer.acceptableContentTypes setByAddingObject:#"text/html"];
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:
[SOUser sharedManager].id, #"id",
#"vk", #"socialId",
[SOUser sharedManager].firstName, #"firstName",
[SOUser sharedManager].lastName, #"lastName",
[SOUser sharedManager].sex, #"gender",
[SOUser sharedManager].friends, #"friends", nil];
[self.manager POST:#"api/user/"
parameters:parameters
success:^(AFHTTPRequestOperation *operation, id responseObject) {
//NSLog(#"Response: %#", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
NSLog(#"OPERATION = %#", operation);
NSLog(#"%#", operation.responseString);
NSLog(#"JSON: %#", responseObject);
NSLog(#"Token = %#", [responseObject objectForKey:#"token"]);
[SOUser sharedManager].legendaryToken = [responseObject objectForKey:#"token"];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
NSLog(#"message: %#", [operation.responseObject objectForKey:#"message"]);
NSLog(#"operation: %#", [operation.responseObject objectForKey:#"errors"]);
NSDictionary *ac = [operation.responseObject objectForKey:#"errors"];
NSLog(#"%#", [ac objectForKey:#"email"]);
NSString *fg = [ac objectForKey:#"email"];
NSLog(#"%#", fg);
}];
Where [SOUser sharedManager].friends is NSMutableArray:
for (int i = 0; i < 25; i++) {
[self.friends addObject:[NSString stringWithFormat:#"%i", i]];
}
And on server i receive all my data but instead of my array with my numbers server print string "array"? What it can be?
My JSON :
JSON: {
email = "<null>";
"fb_friends" = "<null>";
"fb_id" = "<null>";
firstName = Sergey;
gender = 2;
id = 17;
lastName = Oleynich;
phone = "<null>";
token = 6990b71a61411d9d038dad1e2a54dd9f;
"vk_friends" = (
0,
1,
2,
3,
4,
5,
6,
7,
8,
9,
10,
11,
12,
13,
14,
15,
16,
17,
18,
19,
20,
21,
22,
23,
24
);
"vk_id" = 3;
server
JSON : Id:17
vk_id:3
fb_id:NULL
firstName:Sergey
lastName:Oleynich
gender:2
email:NULL
vk_friends:Array

Answer 1

I would suggest that your request might be fine, but that the problem may simply be the manner in which you are displaying the "server" values at the end of your question. For example, if your server was written in PHP and you echo the variable that holds the array of vk_friends, it would simply display "Array".
If you want to display the array in PHP, you'd do something like:
foreach ($vk_friends as $vk_friend) {
echo $vk_friend . "\r\n";
}
Frankly, if your server was responding to the app, you'd probably use json_encode, anyway, and this point is moot. But this might be why you are currently seeing "Array" in your output.
