Using the httpx module

The httpx external module is a Python extension that can consume both asynchronous and synchronous REST APIs and has HTTP/1.1 and HTTP/2 support. It is a fast and multi-purpose toolkit that is used to access API services running on WSGI-based platforms, as well as, on ASGI, like the FastAPI services. But first, we need to install it using pip:

pip install httpx

Then, we can use it directly without further configuration to make two microservices interact, for instance, our student module submitting assignments to the faculty module:

import httpx
@router.get('/assignments/list')
async def list_assignments():

    response = await client.get(
     "http://localhost:8000/ch04/faculty/assignments/list")
    return response.json()
@router.post('/assignment/submit')
def submit_assignment(assignment:AssignmentRequest...
