将PHP soap客户端转换为Python

Question

我尝试使用SOAP API，但文档和示例都是用PHP编写的。这是PHP示例：

<?php

$client = new SoapClient('http://beta.payamsms.com/wsdl?t='.time(), array(
    'location' => 'http://beta.payamsms.com/soap',
    'uri'      => 'http://beta.payamsms.com/soap',
    'use'      => SOAP_LITERAL,
    'style'    => SOAP_DOCUMENT,
    'trace'    => 1
));

//Get customer's balance
$response = $client->getBalance(array(
    'userName'=>'bWvVCxNSeovqJviz7mzZqQ', 
    'password' => '123654789', 
    'facilityId' => 1
));
echo 'Your balance is: ' . $response->getBalanceReturn->balance . PHP_EOL;
echo PHP_EOL;

这是我的python代码：

import time
from suds.client import Client
from suds.xsd.doctor import Import, ImportDoctor


service = "http://beta.payamsms.com/wsdl?t="+int(time.time()).__str__()
doctor = Import("http://beta.payamsms.com/soap")
client = Client(service, doctor=ImportDoctor(doctor))
client_service = client.service.getBalance(userName='bWvVCxNSeovqJviz7mzZqQ', password='123654789', facilityId=1)

但我一直得到例外：（405，＆＃39; Not Allowed＆＃39;）错误。

那么，我接下来应该做什么？
