API 网关日志记录 - 代理 Lambda - 请求路径

Question

我正在尝试将我的 API Gateway 日志推送到 Elasticsearch。除了一个恼人的缺陷外，我有这个工作。我似乎无法获得原始资源路径，因为我正在使用代理 lambda 函数。我将我的 API 日志记录格式设置如下；

{
    "requestId": "$context.requestId",
    "ip": "$context.identity.sourceIp",
    "caller": "$context.identity.caller",
    "user": "$context.identity.user",
    "requestTime": "$context.requestTime",
    "httpMethod": "$context.httpMethod",
    "resourcePath": "$context.resourcePath",
    "status": "$context.status",
    "protocol": "$context.protocol",
    "responseLength": "$context.responseLength"
}

这给了我以下内容；

{
    "requestId": "xxxxxxxxxxxxxx",
    "ip": "xxx.xxx.xxx.xxx",
    "caller": "-",
    "user": "-",
    "requestTime": "16/Apr/2019:11:03:49 +0000",
    "httpMethod": "GET",
    "resourcePath": "/{proxy+}",
    "status": "304",
    "protocol": "HTTP/1.1",
    "responseLength": "0"
}

如何获取实际资源路径而不是/{proxy+}？文档似乎没有说清楚；

Answer 1

原来我应该使用它作为我的 API 日志配置；

{
    "requestId": "$context.requestId",
    "ip": "$context.identity.sourceIp",
    "caller": "$context.identity.caller",
    "user": "$context.identity.user",
    "requestTime": "$context.requestTime",
    "httpMethod": "$context.httpMethod",
    "resourcePath": "$context.path",
    "status": "$context.status",
    "protocol": "$context.protocol",
    "responseLength": "$context.responseLength"
}
