如何获得urllib3和请求使用jython 2.7 beta 1？

Question

聪明人,

我想在我的jython程序中使用awesome requests模块.它在python中安装和运行得很好,但我无法在jython中安装它.我在mac和ubuntu上尝试了Jython 2.7a2和2.7b1,并获得了与urllib3相关的相同错误.

首先安装了如何使用jython setup.py install中提到的ez_setup.py ？

然后从jython bin目录中运行easy_install会导致异常:

NameError: name 'CERT_NONE' is not defined
gautam-mbp:bin gautam$ ./easy_install requests

看起来与urllib3相关的问题与jython不兼容.感谢获取请求(和urllib3)以处理jython的帮助.同样的错误也出现在ubuntu上.

谢谢Gautam

编辑:截至2015年5月,当前稳定版本的请求2.7.0不再受Jython中原始错误的影响--Aprillion

您所面临的错误已经在urllib3和请求的开发版本中修复了一段时间.

因为你将无法安装它,因为它将炸毁pip/easy_install,java.lang.RuntimeException: java.lang.RuntimeException: Class file too large!你必须直接从源代码树运行它.

在那里,您可以通过使用虚拟方法替换所有ssl_wrap_socket内容来修复导入错误,requests/packages/urllib3/util.py例如:

def ssl_wrap_socket(sock, keyfile=None, certfile=None, cert_reqs=None,
                    ca_certs=None, server_hostname=None,
                    ssl_version=None):
    raise Error('This is not meant to be called')

(如果SSL支持是涉及您的利益:它的那一刻被打破反正)

由于jython 缺少对idna的支持,你也必须删除它.转到第290行request/models.py并替换'idna'为'utf-8'.

因此,如果您不需要使用ssl或idna,那么这些步骤应该可行.
