Python请求:似乎无法使用从cookie中获取的csrftoken升级标头

我在向我的HTTP请求正确插入{“X-CSRFTOKEN”:client.cookies ['ccsrftoken']}时遇到了一些问题。

我的想法是使用X-CSRFTOKEN在我的防火墙上进行身份验证。

这是我的代码:

#!/usr/bin/env python
import requests

url = 'http://10.0.2.45/'
name = 'admin'
password = 'xyz'

#all cookies received will be stored in the session object
client = requests.session() 

print 'client headers initially: ', client.headers, '\n'


#First connection used for authentication.
login = client.post(url + '/logincheck', data="username=" + name + "&secretkey=" + password, verify = False)

#csrftoken to be inserted in the headers for next put,post,delete requests. 
This will be stored in csrftoken variable. 
print 'client cookies after login: ', client.cookies, '\n \n'
print 'csrftoken value extracted from the cookie: ', 
client.cookies['ccsrftoken'], '\n \n'

#we update the session headers with X-CSRFTOKEN 
client.headers.update({"X-CSRFTOKEN": client.cookies['ccsrftoken']})

#Simple post command (empty, just to test authentication)
api_cmdb = 'api/v2/cmdb/'
c = client.post(url + api_cmdb + 'firewall/address?vdom=root', verify = False)

在我的防火墙上,这将导致这三个错误:

[httpsd 160 - 1502297425错误] is_valid_csrf_token [3015] - CSRF令牌不匹配

[httpsd 160 - 1502297425错误] api_cmdb_execute_handler [1422] - 找不到有效的CSRF令牌

[httpsd 160 - 1502297425错误] api_return_http_result [528] - 提出API错误403

使用Wireshark并与CURL命令进行比较(工作正常),我可以看到插入“X-CSRFTOKEN”的值是双引号。例如client.headers.update({“X-CSRFTOKEN”:client.cookies ['ccsrftoken']})的输出:

CaseInsensitiveDict({'X-CSRFTOKEN': '"6C369B52B8211679DF2AC9676945CC"', 'Accept-Encoding': 'gzip, deflate, compress', 'Accept': '*/*', 'User-Agent': 'python-requests/2.2.1 CPython/2.7.6 Linux/3.4.0+'})

而这个值应该只插入而没有第二组“引用”。

知道如何纠正这个问题吗?

非常感谢

  

这是来自新sess的client.cookies的输出:

我找到了解决方案。

它只需要一个字符串切片。

如果a = client.cookies ['ccsrftoken'] 然后csrftoken = a [1:-1]

测试后这很好用。
