API网关-消息“选择集成响应”使用cloudformation创建堆栈时

问题描述

这是我期望在创建堆栈后在API Gateway中看到的内容。

但这是实际发生的情况。
在方法响应中，它显示消息“选择积分响应”，但是 我确实在方法响应中添加了模型，并且应该显示“ HTTP状态：代理”
发生了什么事？

              ]
            }
          }
        }
      }
    }
  }

解决方法

只需将其添加到Integration内：

"IntegrationResponses": [{ 
 "ResponseParameters":{
                "method.response.header.Access-Control-Allow-Origin": "'*'"
              },"StatusCode" : "200"
}]

下面的方块

"MethodResponses":[
            {
              "ResponseModels" : {"application/json" : "Empty"},"ResponseParameters":{
                "method.response.header.Access-Control-Allow-Origin": "'*'"
              },"StatusCode" : "200"
            },{
              "StatusCode": "500"
            }
          ],

设置为方法响应级别。您正在查看的lambda表示集成响应级别。为此，您必须设置IntegrationResponses。
