Issue with accents or Special characters in Json (Abap) - web-services

Question

I am consuming a HTTP service from abap.
The service returns me a json with the following data:
{
"statusCode": 200,
"message": "éxito",
"data": [
{
"_id": "584e9469df829275019c4a74",
"nombre": "COCHAMÓ",
"Útil": "Si",
"email": "supervisor#demo.com",
"Sms Número de teléfono": "981363931",
"Llamar al teléfono": "26944444",
"Radio de búsquedaPedido Público(Km) 1": 3,
"Radio de búsquedaPedido Público(Km) 2": 3,
"Radio de búsquedaPedido Público(Km) 3": 3,
"Tiempo de Descarga masa(min)": 10,
"Radio de búsquedaPedido Privado(Km)": 1,
"Cola de Pedidos(n)": 6,
"Tiempo de Esperapara Asignar pedidos(Sgds)": 45,
"Hora de finalización": "21:00"
}
]
}
The code:
Call method cl_http_client=>create_by_url
Exporting
url = lv_url
Importing
client = Data(lcl_client)
Exceptions
argument_not_found = 1
plugin_not_active = 2
internal_error = 3
Others = 4.
If sy-subrc Ne 0.
Raise urlexception.
Else.
Data(lcl_request) = lcl_client->request.
lcl_client->request->set_method( if_http_request=>co_request_method_post ).
lcl_request->set_form_field( name = Parametro1 value = lv_mail ).
lcl_request->set_form_field( name = Parametro2 value = lv_password ).
If idcomuna Is Not Initial.
lv_comunasap = idcomuna.
lcl_request->set_form_field( name = Parametro3 value = lv_comunasap ).
Endif.
If idcomunagc Is Not Initial.
lv_comunamongo = idcomunagc.
lcl_request->set_form_field( name = Parametro4 value = lv_comunamongo ).
Endif.
cl_http_utility=>set_request_uri( request = lcl_request
uri = lv_url ).
Call method lcl_client->send
Exceptions
http_communication_failure = 1
http_invalid_state = 2
http_processing_failed = 3
http_invalid_timeout = 4
Others = 5.
If sy-subrc Ne 0.
Raise sendexception.
Else.
Call method lcl_client->receive
Exceptions
http_communication_failure = 1
http_invalid_state = 2
http_processing_failed = 3
Others = 4.
If sy-subrc <> 0.
Else.
lcl_client->response->get_status( Importing code = Data(lv_code) reason = Data(lv_reason) ).
Data(lv_respuesta) = lcl_client->response->get_cdata( ).
Originally the json should come with accents(Spanish names).
The é, ú are one of the strange characters that it should be letter with accent.
How to get the json full data with accents in my ABAP program?

Answer 1

Whatever it's output on a display or in a variable, #Jagger is right, the response is returned in UTF-8. As you use GET_CDATA (get characters), I think that SAP takes the explicit charset given in the response header (Content-Type: text/json;charset=utf-8), and so it should be converted correctly. If it's not, then maybe the charset is missing in the header.
So, if it's not given, then do the conversion yourself, the same way as for any other UTF-8:
First of all, use GET_DATA (not GET_CDATA) to read it as a string of bytes, then convert it into a string of characters by using the method CONVERT_FROM (codepage = `utf-8`) of the class CL_ABAP_CODEPAGE.
