requests.exceptions.InvalidSchema: No connection adapters were found for 'localhost:8080/'


Problem Code:

resp = requests.post("localhost:8080", auth=("user","pass"), headers={"key":"value"}) 


Solution:

resp = requests.post("http://localhost:8080", auth=("user","pass"), headers={"key":"value"})
