本地运行项目成功 ，但在服务器运行程序就会报Failed to establish a new connection: [Errno -2] Name or service not known

equests.exceptions.ConnectionError: HTTPSConnectionPool(host='appapi.xxxx.com', port=443): Max retries exceeded with url: /appapi/exchange/19/v1/prolist (Caused by NewConnectionError('<urllib3.connection.VerifiedHTTPSConnection object at 0x7fca889818d0>: Failed to establish a new connection: [Errno -2] Name or service not known',))

排查request连接 错误 ，说明是和网络 相关的，

step1:先在服务器端ping 一下测试网址的host

(automationVenv) [root@67 automationTest]# ping appapi.xxx.com
PING appapi.5i5j.com.wswebpic.com (103.254.190.254) 56(84) bytes of data.

64 bytes from 103.254.190.254 (xxx.254.190.254): icmp_seq=4 ttl=55 time=3.07 ms

step2:在本地ping 一下测试网址的host

wangju@wangju-HP-348-G4:~$ ping appapi.xxx.com
PING appapi.xxx.com (47.95.31.237) 56(84) bytes of data.

观查到服务端和本地 同一host指向的ip不一样

解决 办法 就是在服务器端 配置被测网址的host与本地一样

nano /etc/hosts

增加内容如下：

47.95.31.237 appapi.xxx.com

再次运行脚本就可以正常执行了
