Serverless::Function中Api事件的RequestParameters - 它是如何工作的？

Question

【以下的问题经过翻译处理】 我正在尝试使用SAM模板中的JSON编写添加一些查询字符串参数到一个Lambda函数。所有的示例都是使用YAML编写的？有人能指出我哪里出错了吗？

这是定义的片段：

```
    "AreaGet": {
      "Type": "AWS::Serverless::Function",
      "Properties": {
        "Handler": "SpeciesRecordLambda::SpeciesRecordLambda.Functions::AreaGet",
        "Runtime": "dotnet6",
        "CodeUri": "",
        "MemorySize": 256,
        "Timeout": 30,
        "Role": null,
        "Policies": [
          "AWSLambdaBasicExecutionRole"
        ],
        "Events": {
          "AreaGet": {
            "Type": "Api",
            "Properties": {
              "Path": "/",
              "Method": "GET",
              "RequestParameters": [
                "method.request.querystring.latlonl": {
                  "Required": "true"
                },
                "method.request.querystring.latlonr": {
                  "Required": "true"
                }
              ]
            }
          }
        }
      }
    },

```

这是我得到的错误消息：

Resource with id [AreaGet] is invalid. Event with id [AreaGet] is invalid. Invalid value for 'RequestParameters' property. Keys must be in the format 'method.request.[querystring|path|header].{value}', e.g 'method.request.header.Authorization'.

【以下的回答经过翻译处理】 如果你像下面这样用 `{}` 包含数组的元素，它能正常工作吗？

```
"Events": {
    "AreaGet": {
        "Type": "Api",
        "Properties": {
            "Path": "/",
            "Method": "GET",
            "RequestParameters": [
                {
                    "method.request.querystring.latlonl": {
                        "Required": "true"
                    }
                },
                {
                    "method.request.querystring.latlonr": {
                        "Required": "true"
                    }
                }
            ]
        }
    }
}

```
