API网关响应状态为0，集成延迟10000ms

Question

下面是我从API网关自动生成的javascript SDK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，呼叫成功。我将API网关绑定到AWS lambda，作为一个无服务器的函数设置。

我从未见过这种类型的错误，但今天我得到了5个。随后的通话都正常。

编辑：这可能与CORS设置有关吗？API网关似乎每隔一段时间就会出现问题，并且不会发回相应的COR。可能是在功能冷的时候，也许？我不确定。。。

编辑2：我刚刚验证了-我所有的OPTIONSendpoint（用于CORS）都不需要auth或api密钥。所以我不认为是这样。

编辑4：编辑3是错误的，我击中了错误的endpoint。使用curl点击我的API选项endpoint可以正常工作。

编辑5：查看cloudwatch中的API网关日志，下面是它们的样子。。。在这一点上完全迷失了方向。

编辑6：它还显示了10000毫秒的集成延迟。。。。

编辑7：我写的每个函数的开头都是这样的。。。

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函数永远无法实现——没有写入cloud watch的日志。是的，logRequest是我在每个函数中做的第一件事。

编辑8：我在过去的一周左右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，我会更新的。

编辑9：我现在已经看到，由于抛出异常而未处理，这种情况会发生在其他一些endpoint上。然而，这与10000集成延迟错误并不相同。

Answer 1

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程序。大多数情况下，来自定制授权人的拒绝状态将是403禁止状态，但这里似乎有所不同。同时删除根据日志设置的任何基于配额的使用。在我看来，10000的绝对数字似乎是API网关中的一种配置。
