【问题描述】：

这是我从 API Gateway 自动生成的 javascript SDK 返回的错误。

我查看了我的 cloudwatch 日志，调用成功了。我将 API 网关绑定到 AWS lambda 作为无服务器功能设置。

我从未见过这些类型的错误，但今天我遇到了其中的 5 个。随后的调用都奏效了。

编辑：这可能与 CORS 设置有关吗？每隔一段时间，API 网关似乎就会打嗝并且没有发回适当的 CORS。可能是当功能很冷的时候？我不确定...

编辑 2：我刚刚验证过——我的所有 OPTIONS 端点（用于 CORS）都不需要 auth 或 api 密钥。所以我认为不是这样。

编辑 4：编辑 3 错误，我打错了端点。使用 curl 访问我的 API OPTIONS 端点可以正常工作。

编辑 5：查看 cloudwatch 中的 API 网关日志，它们看起来是这样的……此时完全迷失了。

编辑 7： 以下是我编写的每个函数的开头...

module.exports.unsubscribeFromDailyEmails = function(event, context, cb) 
  logRequest(event, context);
//more logic

function logRequest(event, context) 
  console.log('event: ' + JSON.stringify(event));
  console.log('context: ' + JSON.stringify(context));

我想强调一下，在我所说的情况下，永远不会达到 logRequest 功能——没有写入云手表的日志。是的，logRequest 是我在每个函数中做的第一件事。

编辑 8：我在过去一周左右没有看到这种情况发生......所以它可能是在 AWS 方面并且它已修复？如果我发现其他情况，我会更新。

编辑 9：我现在已经看到在其他一些端点上发生了这种情况，因为异常被抛出并且没有被处理。但是，这与 10000 集成延迟错误的情况不同。

【问题讨论】：

您使用自定义授权人吗？

确实很奇怪。你的 Lambda 之外有什么代码？

你能确认你的 lambda 回调总是被调用来结束执行吗？例如您的实现中是否存在可能导致没有 cb() 的随机元素？

@NicholasSizer 是的，我可以确认该调用始终调用 cb，但可能存在未处理的异常。但是，由于我没有看到 logRequest 日志，我怀疑这甚至可能是问题......除非你明白我不明白的东西？

是的，未处理的异常会冒出并最终登录 Cloudwatch。我的想法是，如果不调用 cb，则 lambda 执行将继续，直到超时；听起来这不是原因

【参考方案1】：

我认为你在正确的轨道上，请与 cors 一起阅读它，它将为你很好地布置它。 Click here

【讨论】：

我只是查看了 API 网关（用于 CORS）中的所有“选项”端点，它们都不需要身份验证。它看起来确实与那个帖子非常相似，但是我没有为选项设置任何身份验证。

嗯，当我点击我的 OPTIONS 端点时，我确实得到了一个丢失的身份验证令牌......

我怀疑没有身份验证可能是您的问题

【参考方案2】：

希望您指的是自定义状态代码而不是 http 状态代码。如果连接成功，API 网关将只返回一个非零状态码。要隔离问题，您可以删除此设置中的任何自定义授权人。大多数情况下，来自自定义授权者的拒绝状态将是 403 禁止状态，但这里似乎有所不同。还要删除可能根据日志设置的任何基于配额的使用情况。在我看来，绝对数量 10000 是 API 网关中的配置。

【讨论】：

即是通过自动生成的api网关javascript SDK返回的确切响应对象。我可以进一步深入研究它，我想看看发生了什么......它看起来像自动生成的 sdk 在引擎盖下使用 axios......问题是我无法成功复制问题......它只是随机发生而且我' m 每天处理数千个请求。最近，我在过去一周没有看到它发生......这让我认为这是 AWS 的问题。
