requests.exceptions.ConnectionError: HTTPSConnectionPool(host='appts.xxx.com%20', port=443):

开了5个线程 使用requests.post访问一台服务器

错误提示：

Exception in thread Thread-2:

iled to establish a new connection: [Errno 11001] getaddrinfo failed'))

错误原因：

1.有可能请求过多过快

2.访问的url地址错误（我是此种情况）

解决办法：

加上异常处理，遇到不可访问的url，打印出来。不影响继续访问后续的url

        try:
            response = requests.get(url, verify=False, timeout=5)
        except requests.exceptions.ConnectionError:
            print("Site not rechable", url)
            

 执行脚本后输入结果如下：

[2020-08-13 14:17:24,552][ERROR] https://appapi.xxx.com  is not rechable

由此得知是url拼接错导致发送post请求时不能抵达url

修正url后，可以正常访问了
