如何通过带有身份验证的Google Apps脚本调用云功能?

我正在尝试使用"Hello World"云功能代码示例进行测试，但是当我调用它时，即使我已经将Invoker角色添加到请求者用户电子邮件中，也会出现401 HTTP错误.要运行此功能，我还需要对请求执行其他操作吗?

I'm trying to do a test with the "Hello World" Cloud Function code sample, but when I call it I get 401 HTTP error even I've already added the Invoker role to the requester user email. Is there anything else that I need to do on the request to run this function?

我正在Google脚本中尝试执行以下GET操作:

I'm trying to do the GET like this in Google Scripts:

function test(){
   var url = 'https:******************/HelloWorld';
   var response = UrlFetchApp.fetch(url);
   Logger.log(response.getContentText())
}

Python"Hello World"云函数代码示例为:

And the Python "Hello World" Cloud Function code sample is:

def hello_world(request):
"""Responds to any HTTP request.
Args:
    request (flask.Request): HTTP request object.
Returns:
    The response text or any set of values that can be turned into a
    Response object using
    `make_response <http://flask.pocoo.org/docs/1.0/api/#flask.Flask.make_response>`.
"""
request_json = request.get_json()
if request.args and 'message' in request.args:
    return request.args.get('message')
elif request_json and 'message' in request_json:
    return request_json['message']
else:
    return f'Hello World!'
