我的read()这有问题，注释的那

rom urllib import request
import http.cookiejar
import urllib

url = "http://www.baidu.com"
print("spider")
response1=urllib.request.urlopen(url)
print(response1.getcode())
#print(len(response1.read()))

print("第二种方法")
request_=urllib.request.Request(url)
request_.add_header("user-agent","Mozilla/5.0")
response2=urllib.request.urlopen(request_)
print(response2.getcode())
#print(len(response2.read()))


print("第三种方法")
cj=http.cookiejar.CookieJar()
opener=request.build_opener(request.HTTPCookieProcessor(cj))
request.install_opener(opener)
response3=request.urlopen(url)
print(response3.getcode())
print(cj)
#print(response3.read())
