我正在使用 BeautifulSoup 使用 Python 2.7 抓取网站。这是我的代码:
# -*- coding: utf-8 -*-
from BeautifulSoup import BeautifulSoup
import urllib
import json
url = 'http://www.website.com'
file_pointer = urllib.urlopen(url)
html_object = BeautifulSoup(file_pointer)
type_select = html_object('select',{'id':'which'})
for option in type_select:
value = option('option')
for type_value in value:
type = type_value.contents[0]
param_1 = type_value['value']
print 'Type:', type
url2 = 'http://www/website.com/' + param_1
file_pointer2 = urllib.urlopen(url2)
html_object2 = BeautifulSoup(file_pointer2)
result = json.loads(str(html_object2))
for json1 in result['DATA']:
category = json1[0].title()
param_2 = json1[0]
print ' Category:', category
url3 = 'http://www/website.com/' + param_2 + '&which=' + param_1
file_pointer3 = urllib.urlopen(url3)
html_object3 = BeautifulSoup(file_pointer3)
result2 = json.loads(str(html_object3))
for json2 in result2['DATA']:
sub_category = json2[0]
param_3 = sub_category.replace(' ','+').replace('&','%26')
print ' sub_category:', sub_category
for i in param_3:
if i == 'â':
print i
...
我需要替换'â'
第四个 URL 请求的字符以继续我的抓取,但无论我尝试替换什么(u'\u2019'
、â
等),我都会得到一个UnicodeEncodeError
.
我尝试转换param_3
为字符串(因为它是 BeautifulSoup Navigable String 数据类型)并替换,但我得到了同样的错误,除了我的str(param_3)
行。我终于尝试了这个for循环比较并得到警告:
UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
if i == 'â':
我在这里不知所措。如何翻译此字符并将其替换为 中的其他字符param_3
?
