我正在尝试使用Python 2对页面执行HEAD请求.

我在尝试

import misc_urllib2
.....
opender = urllib2.build_opener([misc_urllib2.MyHTTPRedirectHandler(), misc_urllib2.HeadRequest()])

用misc_urllib2.py含

class HeadRequest(urllib2.Request):
    def get_method(self):
        return "HEAD"


class MyHTTPRedirectHandler(urllib2.HTTPRedirectHandler):
    def __init__ (self):
        self.redirects = []

    def http_error_301(self, req, fp, code, msg, headers):  
        result = urllib2.HTTPRedirectHandler.http_error_301(
                self, req, fp, code, msg, headers)
        result.redirect_code = code
        return result

    http_error_302 = http_error_303 = http_error_307 = http_error_301

但我得到了

TypeError: __init__() takes at least 2 arguments (1 given)

如果我这样做

opender = urllib2.build_opener(misc_urllib2.MyHTTPRedirectHandler())

然后它工作正常
