在大量访问网页时，有可能出现这种报错：
代码语言：javascript复制14-09-2019 12:1138 root: ERROR: HTTPSConnectionPool(host='www.mzitu.com', port=443): Max retries exceeded with url: /187465/31 (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f0bed634f98>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution',))
