API 网关 - 消息“选择集成响应。” 使用 cloudformation 创建堆栈时

Question

这是我希望在创建堆栈后在 API 网关中看到的内容。

但这就是实际发生的事情。
在方法响应中，它显示消息“选择集成响应。”，但我确实在方法响应中添加了 model，并且应该显示“HTTP 状态：代理”
这是怎么回事？

只需将其添加到Integration ：

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

下面这个块

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

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

Answer 2

对于那些正在寻找快速解决方法以使其从控制台运行的人（像我一样）。

我在这里找到了答案： https://github.com/hashicorp/terraform-provider-aws/issues/11561

解决此问题的唯一方法是登录 AWS 控制台并执行以下操作：

Go到“集成请求”，然后取消选中“使用Lambda代理集成”，然后再次勾选。

执行上述步骤后，方法响应正确显示映射的 model。
