Question

我正在尝试通过运动学数据流传输rds，但这给了我这个错误：

botocore.exceptions.ClientError：发生错误（ValidationException）调用PutRecord操作时：1 检测到验证错误：值 'arn：aws：kinesis：us-west-2：xxxxxxxxxx：stream / rds-temp-leads-stream'在 'streamName'无法满足约束：成员必须满足常规表示模式：[a-zA-Z0-9 _.-] +

该如何解决？


import json
import boto3
from datetime import datetime

from pymysqlreplication import BinLogStreamReader
from pymysqlreplication.row_event import (
  DeleteRowsEvent,
  UpdateRowsEvent,
  WriteRowsEvent,
)

class DateTimeEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, datetime):
            return o.isoformat()

        return json.JSONEncoder.default(self, o)

def main():
  mysql = {
      "host": "",
      "port":,
      "user": "",
      "passwd": "",
      "db": ""}
  kinesis = boto3.client("kinesis", region_name = 'us-west-2')

  stream = BinLogStreamReader(
    connection_settings = mysql,
    server_id=100,
    blocking = True,
    log_file='mysql-bin.000003',
    resume_stream=True,
    only_events=[DeleteRowsEvent, WriteRowsEvent, UpdateRowsEvent]) 
  for binlogevent in stream:
    for row in binlogevent.rows:
      print row
      event = {"schema": binlogevent.schema,
      "table": binlogevent.table,
      "type": type(binlogevent).__name__,
      "row": row
      }

      kinesis.put_record(StreamName="jhgjh", Data=json.dumps(event, cls=DateTimeEncoder), PartitionKey="default")
      #print json.dumps(event)

if __name__ == "__main__":
   main()

Answer 1

从流名称中删除“ arn：aws：kinesis：us-west-2：xxxxxxxxxx：stream / rds-temp-leads-stream”。只需将流的名称放在那里，例如“ rds-temp-leads-stream”

Answer 2

基于错误：

<块引用>

检测到 1 个验证错误：“streamName”处的值“arn:aws:kinesis:us-west-2:xxxxxxxxxx:stream/rds-temp-leads-stream”未能满足约束条件：成员必须满足正则表达式模式：[a-zA-Z0-9_.-]+

突出显示的值：arn:aws:kinesis:us-west-2:xxxxxxxxxx:stream/rds-temp-leads-stream 与正则表达式 [a- zA-Z0-9_.-]+ 导致验证错误。

这是因为您无需添加完整的 ARN，只需添加流的名称即可。即 rds-temp-leads-stream

我没有在代码中看到它，但可能这一行出现了错误：

kinesis.put_record(StreamName="jhgjh", Data=json.dumps(event, cls=DateTimeEncoder), PartitionKey="default")

其中“StreamName”应遵循与上述相同的模式。可以在下面找到参考： https://docs.aws.amazon.com/kinesis/latest/APIReference/API_PutRecord.html

就我而言，我还必须像这样删除地址中的子文件夹：

不正确

bucket='s3://image-video/image/'
photo='scene_academy.jpg'

client=boto3.client('rekognition')
response = client.detect_labels(Image={'S3Object':{'Bucket':bucket,'Name':photo}},
        MaxLabels=10)

正确

bucket='image-video'
photo='image/scene_academy.jpg'

client=boto3.client('rekognition')
response = client.detect_labels(Image={'S3Object':{'Bucket':bucket,'Name':photo}},
        MaxLabels=10)

运行时环境：AWS S3 存储桶

验证错误...成员必须满足正则表达式模式：arn：aws：iam ::
