在Lambda函数中无法获取API网关`RequestId`
在Lambda函数中无法获取API网关`RequestId`
提问于 2018-06-30 00:28:07
我发送了一篇帖子，并从amazon API Gateway获得了如下响应：
{"MD5OfMessageBody": "bc709a65868c21309969a07cfeeac12f", "MD5OfMessageAttributes": "8a66ae91e9109cb75717520c287736eb", "MessageId": "b70a5453-5f30-4914-8006-b6cf7fa4ff93", "ResponseMetadata": {"RequestId": "1a38fbb5-859a-53f9-9551-a805d864768c", "HTTPStatusCode": 200, "HTTPHeaders": {"server": "Server", "date": "Fri, 29 Jun 2018 16:18:06 GMT", "content-type": "text/xml", "content-length": "459", "connection": "keep-alive", "x-amzn-requestid": "1a38fbb5-859a-53f9-9551-a805d864768c"}, "RetryAttempts": 0}}当我查看传入lambda：def lambda_handler(event, context):中的处理程序函数的事件对象时

您可以通过使用‘requestId’轻松获取接口网关的事件。
def lambda_handler(event, context):
request = event["requestContext"]
request_id = request["requestId"]Stack Overflow用户
