requests 获取中国统计信息网，内容中文乱码

问题代码

#!usr/bin/python3
# -*- coding: utf-8 -*-
def getData():
   url ="http://www.tjcn.org/tjgb/23sc/35900.html"
   headers = {
            ...
    }
    r = requests.get(url, headers=headers)  
    etree = html.etree
    r.encoding = 'utf-8'
    filename = './data/**.txt'
    with open(filename, 'w', encoding='utf-8') as f:  
    f.write(r.text)

错误结果

修正代码

#!usr/bin/python3
# -*- coding: utf-8 -*-
def getData():
   url ="http://www.tjcn.org/tjgb/23sc/35900.html"
   headers = {
            ...
    }
    r = requests.get(url, headers=headers)  
    etree = html.etree
    r.encoding = 'gb2312'
    filename = './data/**.txt'
    with open(filename, 'w', encoding='utf-8') as f:  
    f.write(r.text)

输出正确 主要是编码方式不同造成的
