代码如下:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
这里提供一种简单的办法解决:使用chardet判断网页的真实编码,同时从url请求返回的info判断标示编码。如果两种编码不同,则使用bs模块扩展为GB18030编码;如果相同则直接写入文件(这里设置系统默认编码为utf-8)。
import urllib2 import sys import bs4 import chardet reload(sys) sys.setdefaultencoding('utf-8') def download(url): htmlfile = open('test.html','w') try: result = urllib2.urlopen(url) content = result.read() info = result.info() result.close() except Exception,e: print 'download error!!!' print e else: if content != None: charset1 = (chardet.detect(content))['encoding'] #real encoding type charset2 = info.getparam('charset') #declared encoding type print charset1,' ', charset2 # case1: charset is not None. if charset1 != None and charset2 != None and charset1.lower() != charset2.lower(): newcont = bs4.BeautifulSoup(content, from_encoding='GB18030') #coding: GB18030 for cont in newcont: htmlfile.write('%s\n'%cont) # case2: either charset is None, or charset is the same. else: #print sys.getdefaultencoding() htmlfile.write(content) #default coding: utf-8 htmlfile.close() if __name__ == "__main__": url = 'http://www.gxlcms.com' download(url)
得到的test.html文件打开如下,可以看到使用的是UTF-8无BOM编码格式存储的,也就是我们设置的默认编码:
