Por que estou obtendo o socket.gaierror com o httplib? [fechadas]

Question

O objetivo do meu programa é enviar uma solicitação de POST para a página de login, mas estou recebendo o seguinte erro.

#!/usr/bin/env python      
import httplib,urllib       
conn = httplib.HTTPConnection("localhost")   
conn.request("GET", "/xampp/mantisbt-1.2.2/login_page.php")  
r1 = conn.getresponse()  
print r1.status, r1.reason   
data1 = r1.read()  
params = urllib.urlencode({'Username': 'administrator', 'Password': 'password'})  
headers = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/html"}  
conn = httplib.HTTPConnection("localhost/xampp/mantisbt-1.2.2/login.php")    
conn.request("POST","localhost/xampp/mantisbt-1.2.2/login.php",params, headers)  
response = conn.getresponse()
print response.status, response.reason
data = response.read()
conn.close()

Linhas 10 e 11 do seu script:

conn = httplib.HTTPConnection("localhost/xampp/mantisbt-1.2.2/login.php")
conn.request("POST","localhost/xampp/mantisbt-1.2.2/login.php",params, headers)

Você está criando um objeto HTTPConnection com os argumentos errados: veja a documentação , a assinatura é:

class httplib.HTTPConnection(host[, port[, strict[, timeout[, source_address]]]])

HTTPConnection aceita o nome do host, HTTPConnection.request () assume o caminho. Portanto, você deve escrever:

conn = httplib.HTTPConnection("localhost")
conn.request("POST","localhost/xampp/mantisbt-1.2.2/login.php",params, headers)
