[rgaricano]

I tried to connect with local or online libretranslate but allways is empty.
When i do directly on webbroser it work:

curl -X 'POST'
'http://127.0.0.1:5000/translate'
-H 'accept: application/json'
-H 'Content-Type: application/x-www-form-urlencoded'
-d 'q=hola&source=es&target=en&format=text&alternatives=3'

Request URL: http://127.0.0.1:5000/translate

Server response: Code 200
{
"alternatives": [
"hi",
"hello",
"hey"
],
"translatedText": "hello"
}

Response headers

access-control-allow-credentials: true access-control-allow-headers: Authorization,Content-Type access-control-allow-methods: GET,POST access-control-allow-origin: * access-control-expose-headers: Authorization access-control-max-age: 1728000 content-length: 63 content-type: application/json date: Mon,15 Jul 2024 10:07:11 GMT server: waitress

I solved it changing http request, removing headers parameter it work, for some reason that function is not working properly:
String v = HttpConnectionUtils.post(serverUrl, params);

Well, I hope work on it for activate API-KEY and alternatives translates.
