JSON decoder error for REST API call to Microsoft Translator

Question

Hello Techies,

I am having a problem with the "response" from request API for Microsoft Translator resource Group. I am getting a JSON decoder error and I can not figure out what is the error and why is it so?

I shall write the code here and also enclose an image showing the outcome.

    'api-version': '3.0',  
    'to': ['en']  
}  
  
BASE_URL = os.getenv('END_POINT')

    """

Hello,

It seems like you have some JSON issue like you try to parse something which Python think is byte stream not a simple string. In order to parse this, you need to convert it into a string first.

Below is my sample code working for me.

import requests, uuid, json  
  
# Add your subscription key and endpoint  
subscription_key = "9d71*****************5ea"  
endpoint = "https://api.cognitive.microsofttranslator.com"  
  
# Add your location, also known as region. The default is global.  
# This is required if using a Cognitive Services resource.  
location = "westus2"  
  
path = '/translate'  
constructed_url = endpoint + path  
  
params = {  
    'api-version': '3.0',  
    'to': ['en']  
}  
constructed_url = endpoint + path  
  
headers = {  
    'Ocp-Apim-Subscription-Key': subscription_key,  
    'Ocp-Apim-Subscription-Region': location,  
    'Content-type': 'application/json',  
    'X-ClientTraceId': str(uuid.uuid4())  
}  
  
# You can pass more than one object in body.  
body = [{  
     'text': 'Mien name ist wichtiger als dein name.'  
}]  
  
request = requests.post(constructed_url, params=params, headers=headers, json=body)  
response = request.json()  
  
print(json.dumps(response, sort_keys=True, ensure_ascii=False, indent=4, separators=(',', ': ')))  

Thanks.
