import requests
url="https://www.amazon.cn/gp/product/B01M8L5Z3Y"
try:
    r=requests.get(url)
    print(r.status_code)
    print(r.request.headers) # 亚马逊识别了此次访问是由'User-Agent': 'python-requests/2.23.0'发起的，故拒绝了访问
    kv={'User-Agent': 'Mozilla/5.0'} # Mozilla/5.0是浏览器身份标识字段 修改User-Agent
    r = requests.get(url,headers=kv)
    print(r.status_code)
    r.raise_for_status() # 如果非200 则触发异常
    r.encoding=r.apparent_encoding
    print(r.text[0:1000])
except:
    print("爬取失败")

结果：
