使用SUDS的空cookiejar

Question

我在Linux Slackware 13.0上使用python 2.6.2运行SUDS 0.4.当我使用此代码调用SOAP方法时:

from suds.client import Client

client = Client(url='file:acctWeb.wsdl',
                location='http://10.242.69.4:8088/pfmaccess')

res = client.service.login(login='user',password='passwd')

我收到以下回复:

DEBUG:suds.transport.http:received:
CODE: 200
HEADERS: {'set-cookie': 'OSP_Ref=0000000573800052;Domain=10.242.69.4:8088;Path=/pfmaccess', 'content-length': '26541', 'content-type': 'text/xml; charset=utf-8', 'connection': 'close', 'server': 'Alcatel-Lucent OSP 2.4'}

但

>>> client.options.transport.cookiejar
<cookielib.CookieJar[]>

表明没有可用的cookie.可能是什么原因？我无法使用SOAP API,因为我需要传递响应cookie中发送的凭据.

请帮帮我.

好吧,我玩过它.

首先,一个小测试服务器(由soaplib提供):

import soaplib
from soaplib.core.service import rpc, DefinitionBase, soap
from soaplib.core.model.primitive import String, Integer
from soaplib.core.server import wsgi
from soaplib.core.model.clazz import Array
import sys, pprint

class HelloWorldService(DefinitionBase):
    @soap(String,Integer,_returns=Array(String))
    def say_hello(self,name,times):
        results = []
        for i in range(0,times):
            results.append('Hello, %s'%name)
        return results

class WsgiApp(wsgi.Application):

    def on_wsgi_return(self, env, headers, return_str):
        headers['Set-Cookie'] = 'spam=eggs;domain=127.0.0.1;path=/'
        print >>sys.stderr, headers

if __name__=='__main__':
    try:
        from wsgiref.simple_server import make_server
        soap_application = soaplib.core.Application([HelloWorldService], 'tns')
        wsgi_application = WsgiApp(soap_application)
        server = make_server('localhost', 7789, wsgi_application)
        server.serve_forever()
    except ImportError:
        print "Error: example server code requires Python >= 2.5"

稍加修改以设置cookie标头.

和suds-testclient:

from suds import client, transport

c = client.Client("http://127.0.0.1:7789/?wsdl")
print c.service.say_hello("spam", 1)
print c.options.transport.cookiejar

运行这会产生:

(stringArray){
   string[] = 
      "Hello, spam",
 }
<cookielib.CookieJar[<Cookie spam=eggs for .127.0.0.1/>]>

所以接缝工作.但如果您更改请求网址,http://localhost:7789/?wsdl您将获得:

(stringArray){
   string[] = 
      "Hello, spam",
 }
<cookielib.CookieJar[]>

cookielib在客户端打开一些日志记录......

import logging
import cookielib
logging.basicConfig()
logging.getLogger('cookielib').setLevel(logging.DEBUG)
cookielib.debug = True

......它揭示了原因:

DEBUG:cookielib:add_cookie_header
DEBUG:cookielib:extract_cookies: Date: Thu, 17 May 2012 15:56:01 GMT
Server: WSGIServer/0.1 Python/2.7.3
Set-Cookie: spam=eggs;domain=127.0.0.1;path=/
Content-Length: 822
Content-Type: text/xml

DEBUG:cookielib: - checking cookie spam=eggs
DEBUG:cookielib:   effective request-host localhost.local (even with added initial
                   dot) does not end with .127.0.0.1
(stringArray){
   string[] = 
      "Hello, spam",
 }
<cookielib.CookieJar[]>

简单的解释是:cookie域与请求的服务器域不匹配,并且cookielib在验证域时似乎不执行任何查找.

所以解决方案将是以下之一:

• 确保客户端和服务器
  在示例中使用相同的域(域名或IP),我必须将两者都设置localhost.local为使其工作(可能取决于hosts文件...)
• 从已发送的cookie中删除域,然后cookieib自动使用请求域
• 实现一个使用DNS查找的cookiejar

哦,最后但并非最不重要:它在OPs问题中不起作用的原因:
端口不是域的一部分,因此cookie Domain=10.242.69.4:8088将始终被拒绝.
