2019-05-13--重学Python28--异步加载get请求数据失败。

'''
1,网址：http://www.cwl.gov.cn/kjxx/ssq/kjgg/ 要爬取的网址。
2，异步调取的数据。"http://www.cwl.gov.cn/cwl_admin/kjxx/findDrawNotice?name=ssq&issueCount=30"
但是当我用request访问这个网址的时候，却没有响应的数据返回，这就很尴尬了！
如何？XHR中的response返回的数据
这个人遇到的问题，跟我遇到的一样！：https://bbs.csdn.net/topics/392498560
