AFNetworking - Translating cURL Put request

Question

This is the PUT request that is succeeding with cURL:

curl -X PUT \
-H 'Accept: application/vnd.layer+json; version=1.1' \
-H 'Authorization: Bearer XXXXXXXXXXX' \
-H 'Content-Type: application/json' \
-d '{"external_unread_count": 13}' \
https://api.layer.com/apps/XXXXX-XXXXX-XXXXX-XXXXX-XXXXXXX/users/XXXXXXX/badge

Here is the API documentation I am trying to mimick:

I am trying to send the same request using AFNetworking:

NSDictionary *params = @{@"external_unread_count": @13};
NURL *baseURL = [NSURL URLWithString: @"https://api.layer.com/apps/XXXXX-XXXX-XXXX-XXXX-XXXXXXXX/users/XXXXXXX""];
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:baseUrl] sessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager.requestSerializer setValue:@"application/vnd.layer+json; version=1.1" forHTTPHeaderField:@"Accept"];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[manager.requestSerializer setValue:@"Bearer XXXXXXXXXXX" forHTTPHeaderField:@"Authorization"];
[manager PUT:@"/badge"
         parameters:params
         success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                      NSLog(@"put successful!");
                }
         failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                      NSLog(@"put error: %@", error);
}];

But I consistently receive this error:

Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: unacceptable (406)" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x125883100> { URL: https://api.layer.com/badge } { status code: 406, headers {

    "Content-Length" = 227;

After reading online, everything said that I wasn't handling the correct response types, so I added this in:

[manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/json", @"text/plain", @"text/html", nil]];

But it still failed with the same error. Any help would be greatly appreciated thank you!

Answer 1

Removing the "/" from the route fixed it. So:

[manager PUT:@"badge"
         parameters:params
         success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                      NSLog(@"put successful!");
                }
         failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                      NSLog(@"put error: %@", error);
}];

works!

In the future I should've looked at the error log closer, it gave a hint as to my malformed url with the line: NSErrorFailingURLKey=https://api.layer.com/badge

That line says it is a failing URL and the URL printed isn't the full URL so I should've known that I messed up the URL format.
