Python SOAP 客户端，授权

Question

我正在尝试对一个外部的API进行授权，这个API是基于SOAP和WSDL的。对于这项技术我没有太多经验，而且API的文档是用PHP写的。我在用Python进行授权时遇到了问题（我尝试过使用SUDS库）。以下是PHP的（可用的）代码：

class HRDConfig {
    public $uid = "__partner_uid__";
    public $pass = "__encoded_cspNr_and_pass__"; // ie. "csp123pass"

    const NS = "https://www.hrd.pl/partnerAPI/";
    const PARTNER = "https://www.hrd.pl/partnerAPI/Partner.php?wsdl";
    const DOMAIN = "https://www.hrd.pl/partnerAPI/Domain.php?wsdl";
    const CERTIFICATE = "https://www.hrd.pl/partnerAPI/Certificate.php?wsdl";
    const CLIENT = "https://www.hrd.pl/partnerAPI/Client.php?wsdl";
    const POLL = "https://www.hrd.pl/partnerAPI/Poll.php?wsdl";
    const INVOICE = "https://www.hrd.pl/partnerAPI/Invoice.php?wsdl";
}

ini_set("soap.wsdl_cache_enabled", "1"); //enable cache
$soap = new SoapClient(HRDConfig::DOMAIN, array("encoding"=>"UTF-8", "exceptions" => true));
$soap->__setSoapHeaders(array(new SoapHeader(HRDConfig::NS, "AuthHeader", new HRDConfig())));

我想把这段代码转到Python上，但一直没有成功。我该如何在SOAP请求中添加AuthHeader（可以使用任何库，比如SUDS或SOAPpy）？有没有什么想法可以帮助我进行授权？

这段内容可以帮助你入门使用 suds，虽然我无法确认它是否真的能工作，因为我没有那个服务的凭证。你只需要创建一个 HRDPartnerAPI 的实例，然后调用 add_authheader 来添加你的 AuthHeader，接着就可以用 .service.<方法名>(<参数...>) 的方式调用任何方法。

import suds.client
from suds.sax.element import Element
from suds.sax.attribute import Attribute

class HRDPartnerAPI(object):

    NS = "https://www.hrd.pl/partnerAPI/"
    PARTNER = "http://www.hrd.pl/partnerAPI/Partner.php?wsdl"
    DOMAIN = "https://www.hrd.pl/partnerAPI/Domain.php?wsdl"
    CERTIFICATE = "https://www.hrd.pl/partnerAPI/Certificate.php?wsdl"
    CLIENT = "https://www.hrd.pl/partnerAPI/Client.php?wsdl"
    POLL = "https://www.hrd.pl/partnerAPI/Poll.php?wsdl"
    INVOICE = "https://www.hrd.pl/partnerAPI/Invoice.php?wsdl"

    def __init__(self, wsdl):
        self.client = suds.client.Client(wsdl)
        self.service = self.client.service

    def add_authheader(self, username, password):
        auth   = Element('AuthHeader');
        login  = Element('uid').setText(username)
        secret = Element('pass').setText(password)
        auth.append(login);
        auth.append(secret);
        self.client.set_options(soapheaders=[auth])

    def list_methods(self):
        return [method for method in self.client.wsdl.services[0].ports[0].methods]

domain = HRDPartnerAPI(wsdl=HRDPartnerAPI.DOMAIN)
print domain.list_methods() # unauth
print domain.service.check("lala.com") # unauth
print domain.service.validateAuthInfo("hrd.pl","abcd") # unauth
print domain.add_authheader("__partner_uid__", "__encoded_cspNr_and_pass__") # add auth info
print domain.service.check("lala.com") # authenticated
print domain.client.last_sent() # DEBUG: show last sent msg, shows AuthHeader is present.
print domain.client.last_received() # DEBUG: show last recv. msg

输出：

[info, domainInSystem, check, changeDns, changePrivacy, createHost, transfer, register, trade, validateAuthInfo, renew, validateTradePw, transferDelete, listByClient, tradeStatus, privacyAddDomain, listAll, privacyRemoveDomain]
{"status":false,"errorCode":"1032","error":"Auth Error"}
{"status":false,"errorCode":"1032","error":"Auth Error"}
None
{"status":false,"errorCode":"1032","error":"Auth Error"}
