To listen to desired host nad port pass the --host <host> and --port <port> flags accordingly.

If you want to listen on all host and HTTP request (with port 80)

uvicorn main.app:app --host 0.0.0.0 --port 80

Usage Example

import requests

reqUrl = "http://<host>:<port>/email/send"

headersList = {
 "Content-Type": "application/json" 
}

payload = json.dumps({
    "email":"[email protected]",
    "body": "Hello from emailer-py"
})

response = requests.request("POST", reqUrl, data=payload,  headers=headersList)

print(response.text)
  • You can use a for loop if you have multiple emails as a list.
