php - AWS-CloudWatch : InvalidSequenceTokenException

Question

我有一个 php worker，我将事件记录到 AWS 可以观看。不幸的是，我在尝试提交时遇到了以下错误。

InvalidSequenceTokenException Error executing "PutLogEvents" on "https://logs.eu-west-1.amazonaws.com"; AWS HTTP error: Client error: POST https://logs.eu-west-1.amazonaws.com resulted in a 400 Bad
Request response: {"__type":"InvalidSequenceTokenException","expectedSequenceToken":"999999999999990356407851919528174 (truncated...) InvalidSequenceTokenException (client): The given sequenceToken is invalid. The next expected sequenceToken is: 495599999999988500356407851919528174642 - {"__type":"InvalidSequenceTokenException","expectedSequenceToken":"495573099999999900356407851919528174642","message":"The given sequenceToken is invalid. The next expected sequenceToken is: 495579999999900356407851919528174642"}

这是我的代码

 $date = new DateTime();
 $instance= = new CloudWatchLogsClient([
                'region' => 'eu-west-1',
                'version' => 'latest',
                'credentials' => [
                    'key' => 'XXX',
                    'secret' => 'XXXX'
                ]
            ]);
        $instance->putLogEvents([
                'logGroupName' => "WorkerLog",
                'logStreamName' => "log",
                'logEvents' => [
                    [
                        'timestamp' => $date->getTimestamp(),
                        'message' => "test log"
                    ]
                ]
            ]);

http://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_PutLogEvents.html

您必须在请求中包含一个序列标记。如果您没有，则必须使用 describeLogStreams ( http://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_DescribeLogStreams.html ) 来获取流序列。

当您调用 putLogEvents 时，您将在响应中获得 nextToken。您还必须为其他人推送到流并使 nextToken 无效的情况做好准备。 (在这种情况下，您需要再次描述流以获取更新的 token )。
