使用requests库中的get()函数访问如下一个网站20次(这里采用必应网为例子),打印返回状态,text内容,计算text()属性和content属性所返回网页内容的长度。

import requests
from bs4 import BeautifulSoup
def getHTMLText(r):
    x = r.status_code
    if x == 200 :
        print("访问成功")
    if x == 404:
        print("访问失败")
    return ‘‘
r = requests.get("https://cn.bing.com/",timeout = 100)
for i in range(1,21):          
    print("第{}次".format(i))
    getHTMLText(r)
url="https://cn.bing.com/"
r=requests.get(url)
print(r.status_code)
r.encoding=UTF-8
print(r.text)

print("text属性长度{}".format(len(r.text)))
print("content属性长度{}".format(len(r.content)))
