无服务器Lambda函数的卷曲和终结点时的{"message":"Missing Authentication Token"}

Question

我已经从这个存储库https://github.com/serverless/examples/tree/master/aws-python-simple-http-endpoint克隆并部署了示例无服务器Lambda函数，它有一个简单地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

并且能够使用serverless invoke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 Gateway‘服务下查找了Lambda函数的端点。

并尝试curl它。但是，我得到了一个关于缺少授权令牌的错误：

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。知道端点返回Missing Authentication Token消息的原因吗？

Answer 1

显然，我忘记了像Github示例中那样将/ping附加到URL中。正如在https://docs.aws.amazon.com/apigateway/latest/developerguide/amazon-api-gateway-using-stage-variables.html上记录的那样，

所以我用/ping输入网址，得到了预期的结果：
