我们从Python开源项目中，提取了以下4个代码示例，用于说明如何使用cookielib.request_host()。
def test_request_host(self): from urllib2 import Request from cookielib import request_host # this request is illegal (RFC2616, 14.2.3) req = Request("http://1.1.1.1/", headers={"Host": "www.acme.com:80"}) # libwww-perl wants this response, but that seems wrong (RFC 2616, # section 5.2, point 1., and RFC 2965 section 1, paragraph 3) #self.assertEqual(request_host(req), "www.acme.com") self.assertEqual(request_host(req), "1.1.1.1") req = Request("http://www.acme.com/", headers={"Host": "irrelevant.com"}) self.assertEqual(request_host(req), "www.acme.com") # not actually sure this one is valid Request object, so maybe should # remove test for no host in url in request_host function? req = Request("/resource.html", headers={"Host": "www.acme.com"}) self.assertEqual(request_host(req), "www.acme.com") # port shouldn't be in request-host req = Request("http://www.acme.com:2345/resource.html", headers={"Host": "www.acme.com:5432"}) self.assertEqual(request_host(req), "www.acme.com")
