python爬虫错误 之 write() argument must be str, not bytes

当遇到标题的错误时候，请把以写的方式读入文件即

    with open('./baidu.txt','w') as fp:
        fp.write(response.read())

改成”w”改成”wb+“，意思是将原来的以写方式打开文件，改为以二进制模式打开文件

 # urllib模块:请求返回网页
 # 主要函数：urlopen():打开http,https,ftp协议的url
 # geturl():返回url的信息
 # getcode():返回response的状态代码
 # info():返回response的基本信息
import urllib.request
import time
import platform
def clear():
     print('翻页')
     time.sleep(3)
     os = platform.system()
     if(os == 'Windows'):
         os.system('cls')
     else:
         os.system('clear')
def linkbaidu():
    url = 'http://www.baidu.com'
    try:
        response = urllib.request.urlopen(url,timeout=3)
    except urllib.request.URLError:
        print('网络地址错误')
    with open('./baidu.txt','wb+') as fp:
        fp.write(response.read())
    print("获取url信息, responce.geturl() \n: %s" %response.geturl())
    print("获取返回代码:,response.getcode() \n %s" %response.getcode())
    print("获取返回信息,response.info() \n %s" %response.info())
