进程已结束，退出代码为 1

通常的原因：

频繁的请求服务器，导致服务器发爬虫的怀疑，被网站认定为攻击行为，最终抛出 10054异常。

解决办法：

1、在请求之间加入随机等待时间。
2、每次请求之后执行response.close
3、随机使用不同的agent进行访问。
4、使用代理IP。

具体实现：

1、随即插入1-15秒的等待时间：
import dandom
pasue= random.random()*10
time.sleep(pasue)
2、关闭链接，requests.get后即关闭链接
rsp = requests.get(url,headers=headers)
rsp.close()
3、useragent随机
user_agent = [

调用的时候随即选择
'User-Agent':random.choice(user_agent)
4、免费的代理IP不好找，所以不使用。
