相关疑难解决方法(0)

我在Ubuntu 12.10上使用OpenSSL 1.0.1c,python 2.7.3,请求 1.0.3和1.0.4(尝试过两者),并尝试使用以下代码连接到url变量中的网站.

def SendInitialRequest(xmlmessage, redirecturl):
    url = 'https://centineltest.cardinalcommerce.com/maps/txns.asp'

    payload = 'cmpi_msg=' + ET.tostring(xmlmessage)
    headers = {
        'Content-Type': 'application/x-www-form-urlencoded',
    }
    r = requests.post(url, data=payload, headers=headers, verify=None)
    print r.text

它会引发以下错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "clams/libs/centinel/thinclient.py", line 134, in SendInitialRequest
    r = requests.post(url, data=payload, headers=headers, verify=None)
