C＃AWS API Gatway Post Params

Question

API Gatway Post vars（イベント['body'] ['param']）がC＃Lambda Funcionに渡される方法を理解していますか？

私が持っている：

public string FunctionHandler(Stream request, ILambdaContext context) 
{ StreamReader reader = new StreamReader(request); 
return reader.ReadToEnd(); 
} 

しかし、郵便配達（ポストキー値： "こんにちは：世界"）を使用して、それが返されます。

'\"body-json\" : \"LS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLTcwMTQxNDY5ODUyNjQwNzI2NDM3ODU2OQ0KQ29udGVudC1EaXNwb3NpdGlvbjogZm9ybS1kYXRhOyBuYW1lPSJUaGlzS2V5CiINCg0KV2hhdA0KLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLS0tLTcwMTQxNDY5ODUyNjQwNzI2NDM3ODU2OS0tDQo=' 

（それが表すようになっているものも考えて）

私が行う場合：

public string FunctionHandler(APIGatewayProxyRequest request, ILambdaContext context) 
{ return "request body is:" + request?.Body; } 

I「要請本体：」

空のボディですか？

投稿値はどこですか？

これは、フォーム・データを使用しており、ボディマッピングがある：いいえ、まだ体のために私にGiberishを与える
