AWS 上的 Websocket 连接总是会导致太多请求，即使只有一个请求

Question

所以我有这个 terraform，它似乎部署了一个到 AWS 的 websocket api 连接，但是...部署后，当我连接时，我总是收到“429 请求太多”错误。使用 terraform 0.13.4。我已经在控制台中手动打开了请求，但每次我wscat -c {MYENDPOINT}都会收到 429。无法在网上找到任何内容或手册中与此相关的任何内容。这是地形。想知道是否有人可以看到我的路线或集成中是否遗漏了某些内容？这是我不断从日志中得到的响应： (VH_SDESljoEF7tg=) Gateway response body: { "message": "Too Many Requests", "connectionId": "VH_SDd21joECIeg=", "requestId": "VH_SDESljoEF7tg=" }

Answer 1

我无法解释限制的原因，但我将此块添加到我的aws_apigatewayv2_stage资源中，触发了新的部署，现在我可以使用以下方式进行连接wscat：

  default_route_settings {
    throttling_rate_limit = 100
    throttling_burst_limit = 50
  }
