How to run server in localhost:

from the directory where the CentBotAWS is cloned open the pipenv shell

pipenv shell

pipenv install

Test backnned using api platform

To test the endpoint use api platforms like hopscotch, insomnia, postman or CURL.

Using one of those api platform sent the json as body of the post request to localhost server. Most of the time it would be hosted at http://127.0.0.1:8000/ and the route is /chat/centbot.

TLDR: Sent the POST request request to

http://127.0.0.1:8000/chat/centbot

with body having

{
   "question"      : "Hello",
   "sourceLanguage": "en",
   "targetLanguage": "fr",
   "audioNeeded"   : true
}

and a response as following should be received

{
   "answer"        : "Bonjour ! Je suis CentBot, comment puis-je vous aider ?",
   "sourceLanguage": "en",
   "targetLanguage": "fr",
   "audioFileName" : "Celine_fr-FR_1711787452.mp3"
}

this suggests the translation worked and audio file is generated in the specified audio path. If you don't want audio then set audioNeeded as false.

NB

sourceLanguage should always be en

targetLanguage should be in the following list

{
"supportedTargetLanguageList": [
       "en",
       "es",
       "fr",
       "de",
       "it",
       "pt",
       "nl",
       "ru",
       "ja",
       "ko",
       "zh",
       "ar",
       "hi",
       "tr"
    ]
}

text cannot be empty
