To obtain the token ID of iMaster NCE, you need to send an HTTP request...

The provided Python code uses the requests.post() function to make an HTTP POST request to retrieve a token from iMaster NCE. The body is structured using the json={} parameter, which serializes the dictionary into JSON format. The proper content-type and accept headers are included.

Let's analyze each option:

✅ Option A is correct: The print(r.json()) is a valid method to display JSON response from the server.

✅ Option B is correct: The token URL is constructed correctly: https://139.9.213.72:18002/controller/v2/tokens.

✅ Option C is correct: The request body is clearly in JSON format, specified by the json={...} argument.

❌ Option D is incorrect: The HTTP method used is POST, not GET. The statement is false, making it the correct answer to select.

Huawei Official Documentation Reference:

“To obtain a token, the client sends a POST request to /controller/v2/tokens, including credentials in the request body in JSON format.”
