python3中構造http的Request需要用到urllib.request.?有時會用到cookie。 比如在訪問網站首頁得到cookie，通過下面代碼添加cookie： ? ?#install cookie **??? cj = cookiejar.CookieJar(); ??? opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor(cj)); ??? urllib.request.install_opener(opener)** ??? #build request for accessed url ??? homeReq = urllib.request.Request( ???????? url = csdnAccessModuleUrl ???????? ) ??? homeReq.add_header('Accept', 'text/html, application/xhtml+xml, */*'); ??? homeReq.add_header('Accept-Language', 'en-US') ??? homeReq.add_header('Accept-Encoding', 'gzip, deflate') ??? homeReq.add_header('Connection', 'Keep-Alive'); ??? homeReq.add_header('Referer', 'http://passport.csdn.net/account/login?from='+urllib.parse.quote(moduleUrl))#http%3a%2f%2fwrite.blog.csdn.net%2f') ??? homeReq.add_header('User-Agent', 'Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)'); ??? #open access url ??? resp = urllib.request.urlopen(homeReq) 在上述代碼運行后， 我們可以獲取到cookie，?然后在后續登陸中用到此cookie。
