+ The `AFHTTPClientParameterEncoding` value corresponding to how parameters are encoded into a request body for request methods other than `GET`, `HEAD` or `DELETE`. This is `AFFormURLParameterEncoding` by default.
 
  @warning Some nested parameter structures, such as a keyed array of hashes containing inconsistent keys (i.e. `@{@"": @[@{@"a" : @(1)}, @{@"b" : @(2)}]}`), cannot be unambiguously represented in query strings. It is strongly recommended that an unambiguous encoding, such as `AFJSONParameterEncoding`, is used when posting complicated or nondeterministic parameter structures.
