connect_to_splunk（）恰好接受2个参数（给定1个）

Question

Splunk_WAN_Methods

class Splunk_Methods(object):

结果有误

Could not connect to Splunk
connect_to_splunk() takes exactly 2 arguments (1 given)

Answer 1

def __init__(self, username, password, hostname, port):

这意味着在实例化Splunk_Methods（）时必须传递所有这些参数，例如

Splunk_Methods('user','pass','google.com',1337)
