Connect to an URI in postgres

Question

I\'m guessing this is a pretty basic question, but I can\'t figure out why:

import psycopg2
psycopg2.connect(\"postgresql://postgres:postgres@localhost/postgres\         


        

Answer 1

I would use the urlparse module to parse the url and then use the result in the connection method. This way it's possible to overcome the psycop2 problem.

import urlparse # for python 3+ use: from urllib.parse import urlparse
result = urlparse.urlparse("postgresql://postgres:postgres@localhost/postgres")
# also in python 3+ use: urlparse("YourUrl") not urlparse.urlparse("YourUrl") 
username = result.username
password = result.password
database = result.path[1:]
hostname = result.hostname
port = result.port
connection = psycopg2.connect(
    database = database,
    user = username,
    password = password,
    host = hostname,
    port = port
)
