gaierror：[错误-2]产品名称或服务不知道

Question

def make_req(data, url, method='POST') 
    params = urllib.urlencode(data) 
    headers = {"Content-type": "application/x-www-form-urlencoded", 
       "Accept": "text/plain", 
       } 
    conn = httplib.HTTPSConnection(url) 
    conn.request(method, url, params, headers) 
    response = conn.getresponse() 
    response_data = response.read() 
    conn.close() 

但它抛出：in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): gaierror: [Errno -2] Name or service not known

的原因是什么？这个错误是什么？

Answer 1

您需要使用相对于服务器的URI调用request（）。如果url是www.google.com/images?q=test你必须这样做：

conn = httplib.HTTPSConnection('www.google.com') 
conn.request('GET', '/images?q=test')
