i use
afhttprequestserializer *serializer = [afhttprequestserializer serializer]; and sends out call server when having array in format:
payments[] payments[][email]=0& payments[][category]=& payments[][email]=1& payments[][category]=& i need indexes server like.
payments[] payments[0][email]=0& payments[0][category]=& payments[1][email]=1& payments[1][category]=& how can achieve that?
thanks.
afhttprequestserializer has method setquerystringserializationwithblock allows provide own block serializing parameters.
unfortunately, the internal af* functions serialization private, can copy them , make small modification in these lines add indexes.
to set own serialization block:
[serializer setquerystringserializationwithblock:^nsstring *(nsurlrequest *request, id parameters, nserror *__autoreleasing *error) { return zafquerystringfromparameterswithencoding(parameters, serializer.stringencoding); }]; including code, afnetworking functions have been copied , prefixed z zaf:
