[英]Python request fails from google cloud platform (app engine & cloud shell)
I have a very simple python http request which works on my local machine, but does not work in google app engine or from the google cloud shell. 我有一个非常简单的python http请求,该请求可在我的本地计算机上运行,但不适用于google app引擎或google cloud shell。 There must be config that is messing with the request, but I can't seem to find the problem. 必须有配置弄乱了请求,但我似乎找不到问题。
I am using python 3.7 我正在使用python 3.7
The code that causes the exception is the following (I have replaced the actual URL by example.com) 导致异常的代码如下(我已经用example.com替换了实际的URL)
(The service I need to call is listening on port 6123) (我需要呼叫的服务正在侦听端口6123)
import requests
myrequest = requests.get("http://example.com:6123/something?param=123")
The full error message I get is the following: 我收到的完整错误消息如下:
