問題描述

測試一個非常簡單的爬蟲，把一個非常簡約風格的網頁的文本內容保存到本地的電腦上。最后出現錯誤：

UnicodeEncodeErrorTraceback (most recent call last)<ipython-input-35-ead5570b2e15> in <module>() 7 filename=str(i)+’.txt’ 8 with open(filename,’w’)as f:----> 9 f.write(content) 10 print(’當前小說第{}章已經下載完成’.format(i)) 11 f.close()UnicodeEncodeError: ’gbk’ codec can’t encode character ’xa0’ in position 7: illegal multibyte sequence

代碼如下：

In [1]: import requestsIn [2]: from bs4 import BeautifulSoupIn [3]: re=requests.get(’http://www.qu.la/book/168/’)In [4]: html=re.textIn [5]: soup=BeautifulSoup(html,’html.parser’)In [6]: list=soup.find(id='list')In [9]: link_list=list.find_all(’a’)In [14]: mylist=[] ...: for link in link_list: ...: mylist.append(’http://www.qu.la’+link.get(’href’)) ...: ...:#遍歷每個鏈接，下載文本內容到 本地文本文件i=0 ...: for url in mylist1: ...: re1=requests.get(url) ...: html2=re1.text ...: soup=BeautifulSoup(html2,'html.parser') ...: content=soup.find(id='content').text.replace(’chaptererror();’, ’’) ...: filename=str(i)+’.txt’ ...: with open(filename,’w’)as f: ...: f.write(content) ...: print(’當前小說第{}章已經下載完成’.format(i)) ...: f.close() ...: i=i+1

問題解答

f.write(content.encode(’utf-8’))

或者

import codecswith codecs.open(filename, ’w’, ’utf-8’) as f: f.write(content)
