{“ message”：“缺少身份验证令牌”}卷曲和无服务器Lambda函数的端点

Question

我已经从此存储库https://github.com/serverless/examples/tree/master/aws-python-simple-http-endpoint中克隆并部署了示例无服务器Lambda函数，该函数具有一个可以简单打印当前时间的端点：

import json
import datetime


def endpoint(event, context):
    current_time = datetime.datetime.now().time()
    body = {
        "message": "Hello, the current time is " + str(current_time)
    }

    response = {
        "statusCode": 200,
        "body": json.dumps(body)
    }

    return response

我已经部署了它：

> serverless deploy list functions
Serverless: Listing functions and their last 5 versions:
Serverless: -------------
Serverless: currentTime: $LATEST, 1

并能够使用serverless invoke来调用它：

> serverless invoke --function currentTime --log
{
    "body": "{\"message\": \"Hello, the current time is 22:51:06.872660\"}",
    "statusCode": 200
}
--------------------------------------------------------------------
START RequestId: d4629611-e16b-4afa-80ef-5ac1a7331679 Version: $LATEST
END RequestId: d4629611-e16b-4afa-80ef-5ac1a7331679

在AWS控制台中，我在“ API网关”服务下查找了Lambda函数的端点，

，并尝试curl。但是，我因缺少授权令牌而收到错误消息：

curl https://x6gnvhuuzh.execute-api.us-east-1.amazonaws.com/dev
{"message":"Missing Authentication Token"}⏎  

根据该示例的README.md，我应该看到与serverless invoke相同的输出。知道端点为何返回Missing Authentication Token消息了吗？

Answer 1

显然，我忘了像Github示例中那样，在URL后面附加/ping。如https://docs.aws.amazon.com/apigateway/latest/developerguide/amazon-api-gateway-using-stage-variables.html所述，

所以我用/ping输入了URL，并得到了预期的结果：
