API 网关响应状态为 0，集成延迟 10000ms

Question

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

{
"data": "",
"status": 0,
"statusText": "",
"headers": {
},
"config": {
"method": "POST",
"headers": {
"Content-Type": "application/json",
"Accept": "application/json",
"x-amz-date": "20180127T231842Z",
"Authorization": "AWS4-HMAC-SHA256 Credential=.....",
"x-amz-security-token": "....."
},
"timeout": 0,
"transformRequest": [null],
"transformResponse": [null],
"url": "https://somevalues.execute-api.us-west-2.amazonaws.com/env/some/path",
"data": "{"startDay":0,"endDay":1}"
}
}

我查看了我的 cloudwatch 日志，调用成功。 我将 API 网关绑定到 AWS lambda 作为无服务器函数设置。

我从未见过这些类型的错误，但今天我收到了其中的 5 个。 随后的调用都有效。

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，并且不会发回相应的 CORS。 可能是当功能冷的时候？ 我不确定。。。

编辑 2：我刚刚验证了 - 我所有的 OPTIONS 端点(用于 CORS 的端点)都不需要身份验证或 api 密钥。 所以我不认为是这样。

编辑4：编辑 3 错误，我击中了错误的端点。 使用 curl 访问我的 API 选项端点工作正常。

编辑 5：查看 cloudwatch 中的 API 网关日志，它们是这样的...... 此时完全迷失了。

编辑6： 它还显示了 10000 毫秒的集成延迟。

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));
}

我想强调的是，在我所说的情况下，logRequest 函数永远不会达到 - 没有日志写入云观察。 是的，logRequest 是我在每个函数中做的第一件事。

编辑8：在过去的一周左右的时间里，我没有看到这种情况发生...... 所以也许它在AWS方面并且是固定的？ 如果我发现其他情况，我会更新。

编辑 9：由于抛出且未处理异常，我现在看到这种情况发生在其他一些端点上。 但是，这与 10000 集成延迟错误的情况不同。

Answer 1

我认为您走在正确的轨道上，有了cors，请阅读此内容，它将为您很好地布置。 点击这里

Answer 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 网关将仅返回非零状态代码。要隔离问题，您可以删除此设置中的任何自定义授权方。大多数情况下，自定义授权方的拒绝状态是 403 禁止状态，但这里似乎有所不同。此外，请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，10000 的绝对数字是 API 网关中的配置。
