我想实现我的使用计划如下：创建日志组在AWS上
的CloudWatch上文创建上面日志组Put日志事件日志流
日志流

所有这些都用go lang

package main

import (
    "time"
    "fmt"
    "github.com/jcxplorer/cwlogger"
    "github.com/aws/aws-sdk-go/service/cloudwatchlogs"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/aws"
)

func main() {
    sess := session.Must(session.NewSessionWithOptions(session.Options{
        SharedConfigState: session.SharedConfigEnable,
    }))

    svc := cloudwatchlogs.New(sess)
    logGroupName := "my-log-group";
    logStreamName := "my-log-stream";
    logGroupInput := cloudwatchlogs.CreateLogGroupInput{LogGroupName: &logGroupName}
    svc.CreateLogGroup(&logGroupInput);
    logStreamInput := cloudwatchlogs.CreateLogStreamInput{LogGroupName: &logGroupName, LogStreamName: &logStreamName}
    svc.CreateLogStream(&logStreamInput)

    logevents := make([]*cloudwatchlogs.InputLogEvent, 1)

    logevents = append(logevents, &cloudwatchlogs.InputLogEvent{
        Message:   aws.String("Simple log message"),
        Timestamp: aws.Int64(111),
    })

    p := cloudwatchlogs.PutLogEventsInput{LogEvents: logevents, LogGroupName: &logGroupName, LogStreamName: &logStreamName}
    resp, err := svc.PutLogEvents(&p)
    if err != nil {
        panic(err)
    }
    fmt.Print("Next Token: {}", resp.NextSequenceToken)
}

现在，当我运行上述代码时，它成功创建了日志组和日志流，
并且可以在AWS CloudWatch中进行验证。但是由于某些原因，PutLogEvents
失败并显示以下错误：

panic: SerializationException: 
    status code: 400, request id: 0685efcc-47e3-11e9-b528-81f33ec2f468

我不确定这里可能出什么问题。任何建议或指示将
非常有帮助。

提前致谢。
