先运行如下代码：
import requests
r=requests.get("https://www.amazon.cn/gp/product/B01M8L5Z3Y")
r.status_code
运行结果为：
200
这部分结果和老师的就有所不同了，老师那边返回的是503，查看结果之后发现是代理user-agent了问题，所以对user-agent进行了设置，这里两种均尝试下
方法1：
#未修改user-agent
import requests
url="https://www.amazon.cn/gp/product/B01M8L5Z3Y"
try:
r=requests.get(url)
r.raise_for_status()
r.encoding=r.apparent_encoding
print(r.text[2000:3000])
except:
print("爬取失败")
运行结果为：

方法2：
#修改user-agent
import requests
url="https://www.amazon.cn/gp/product/B01M8L5Z3Y"
try:
kv={'user-agent':'Mozilla/5.0'}
r=requests.get(url,headers=kv)
r.raise_for_status()
r.encoding=r.apparent_encoding
print(r.text[2000:3000])
except:
print("爬取失败")
运行结果为：

这部分和之前结果竟然不一样，也是挺神奇的，后续再探索原因。
