檢查一下html_parser中_get_new_urls方法的return new_urls語(yǔ)句的縮進(jìn)。應(yīng)放在for循環(huán)外

print u'第三種方法'
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)
response3 = urllib2.urlopen(url)
print response3.getcode()
print len(response3.read())
print cj
print response3.read()
cj = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)
response3 = urllib2.urlopen(url)
print response3.getcode()
print len(response3.read())
print cj
print response3.read()

我的代碼,改正了一些錯(cuò)誤,可以運(yùn)行。
# coding:utf-8
import urllib2
import cookielib
url = "http://www.baidu.com"
print u'第一種方法'
response1 = urllib2.urlopen(url)
print response1.getcode()
print len(response1.read())
# coding:utf-8
import urllib2
import cookielib
url = "http://www.baidu.com"
print u'第一種方法'
response1 = urllib2.urlopen(url)
print response1.getcode()
print len(response1.read())

復(fù)制筆記的代碼時(shí)注意縮進(jìn),,,我在_get_new_urls函數(shù)里把return new_urls寫(xiě)進(jìn)for循環(huán)里了,結(jié)果循環(huán)一次就返回了鏈接,所以整個(gè)程序爬了一個(gè)鏈接就停了。

html_outputer代碼里,在寫(xiě)入<html>和<body>之間,再寫(xiě)入<head><meta charset="utf-8"></head>像下面這樣:????????fout=open('output.html','w')? ? ? ? fout.write("<html>")? ? ? ? fout.write("<body>")? ? ? ? fout.write("<head>")? ? ? ?...
還在講python2.x,無(wú)語(yǔ)!
就像和現(xiàn)代人講活字印刷一樣好笑!
