利用chardet检测网页编码

环境：Win7_x64 + python3.4.3

需要先下载chardet并进行安装，下载地址：https://pypi.python.org/packages/source/c/chardet/chardet-2.3.0.tar.gz

安装：进入解压后的目录，在命令窗口执行: Python setup.py install

写个测试的python脚本吧(DetectURLCoding.py)：

#coding:utf-8
'''''python 3.x'''  

import sys
import urllib.request
import chardet  

# 将data写入文件fname
def writeFile(fname, data):
    f = open(fname, "wb")
    if f:
        f.write(data)
        f.close()  

def blog_detect(blogurl):
    '''''检测编码方式'''
    try:
        fp = urllib.request.urlopen(blogurl)
    except Exception as e:
        print(e)
        print('download exception-[%s]' %blogurl)
        return 0
    blog = fp.read()    # python3.x read the html as html code bytearray
    fp.close()
    #writeFile("t.html", blog)  

    # get encoding string
    codedetect = chardet.detect(blog)['encoding']
    print('%s <- %s' %(blogurl, codedetect))
    return 1  

if __name__=='__main__':
    if len(sys.argv) == 1:
        print('''''usage:
            python DetectURLCoding.py http://xxx.com''')
    else:
        v = blog_detect(sys.argv[1])
        print(v)  # 何问起 hovertree.com

运行结果：

D:\profile\Desktop>PYTHON de.py http://hovertree.com/
http://hovertree.com/ <- utf-8
