AWS SDK for PHP で出たエラー

Last updated at 2016-04-19Posted at 2016-04-19

vagrant上からaws sdk for PHPを使ってアクセスしていた時の事。いきなり以下のようなエラーログがでてきてlistObjectsがエラーとなる事象に

2016-04-19 14:46:58] Server.CRITICAL: Aws\S3\Exception\S3Exception: Error executing "ListObjects" on "https://s3-ap-northeast-1.amazonaws.com/hoge-assets?prefix=kakikubo&encoding-type=url"; AWS HTTP error: Client error response [url] https://s3-ap-northeast-
1.amazonaws.com/assets?prefix=kakikubo&encoding-type=url [status code] 403 [reason phrase] Forbidden RequestTimeTooSkewed (client): The difference between the request time and the current time is too large. - <?xml version="1.0" encoding="UTF-8"?> <Error><Code>RequestTimeTooSkewed</Code><Message>The difference between the request time and the current time is too large.</Message><RequestTime>20160419T054656Z</RequestTime><ServerTime>2016-04-19T06:02:40Z</ServerTime><MaxAllowedSkewMilliseconds>900000</MaxAllowedSkewMilliseconds><RequestId>11E8E8CEEE006EDB</RequestId>

"Forbidden RequestTimeTooSkewed"って一瞬なんのことかと思いましたが、どうやら時刻が問題みたいでした。AWS SDKを叩いたクライアント側の時刻と、エンドポイント側の時刻がずれすぎなのが問題のようなので、

$ sudo ntpdate ntp.nict.jp
19 Apr 15:03:23 ntpdate[4495]: step time server 133.243.238.243 offset 941.644282 sec

とすれば解消しました。

眠いのでメモ書きしたかったのでした
