Grab无法连接强制SSLv3的服务器

Question

我正在尝试使用 grab（版本 0.4.8）连接这个网址：'https://myvodafone.vodafone.in/myvodafoneselfcare/jsp/commons/login.jsp'。但是我遇到了以下错误。

ERROR:in_vodafone:17162:375: (<class 'grab.error.GrabNetworkError'>, GrabNetworkError(35, 'error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000)'), <traceback object at 0x10277cb00>)

    raise error.GrabNetworkError(ex[0], ex[1])
GrabNetworkError: [Errno 35] error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000)

我的脚本里有以下代码：

from grab import Grab
g = Grab()
g.setup(hammer_mode = True, hammer_timeouts = ((100, 200), (300, 400), (500, 600)))
g.go('https://myvodafone.vodafone.in/myvodafoneselfcare/jsp/commons/login.jsp')

我发现 urllib 有一个解决方案可以修复这个问题，具体可以查看这个链接：http://bugs.python.org/issue11220。我该如何将这个解决方案应用到 grab 工具上呢？

Answer 1

我找到了以下解决方案，效果很好。

from grab import Grab
import pycurl

g = Grab()
g.transport.curl.setopt(pycurl.SSLVERSION, 3)
g.setup(hammer_mode = True, hammer_timeouts = ((100, 200), (300, 400), (500, 600)))
g.go('https://myvodafone.vodafone.in/myvodafoneselfcare/jsp/commons/login.jsp')
