amazon-web-services - aws lambda : invoke with payload from cli

Question

我正在尝试使用 aws cli 调用我的 lambda:

$ aws lambda invoke \
    --function-name soc-update-dynamodb-java \
    --invocation-type Event \
    --payload file://invoke-payload.json \
   response.json

但是，我收到此消息:

An error occurred (InvalidRequestContentException) when calling the Invoke operation: Could not parse request body into json: Invalid UTF-8 middle byte 0x28 at [Source: (byte[])"E�(�����U�슉���ޞԨ��k.....

payload.json 内容是一个类似 s3 事件的 json:

{
"Records": [
  {
    "eventVersion": "2.0",
    "eventSource": "aws:s3",
    "awsRegion": "eu-central-1",
    "eventTime": "1970-01-01T00:00:00.000Z",
    "eventName": "ObjectCreated:Put",
    "userIdentity": {
      "principalId": "EXAMPLE"
    },
    "requestParameters": {
      "sourceIPAddress": "127.0.0.1"
    },
    "responseElements": {
      "x-amz-request-id": "EXAMPLE123456789",
      "x-amz-id-2": "EXAMPLE123/5678abcdefghijklambdaisawesome/mnopqrstuvwxyzABCDEFGH"
    },
    "s3": {
      "s3SchemaVersion": "1.0",
      "configurationId": "testConfigRule",
      "bucket": {
        "name": "soc-connect",
        "ownerIdentity": {
          "principalId": "EXAMPLE"
        },
        "arn": "arn:aws:s3:::example"
      },
      "object": {
        "key": "example.key",
        "size": 1024,
        "eTag": "0123456789abcdef0123456789abcdef",
        "sequencer": "0A1B2C3D4E5F678901"
      }
    }
  }
]
}

我可以使用此事件从 aws Web 控制台执行它，但是我在尝试使用 aws cli 调用它时遇到问题。

我从 invoke-payload.json 得到编码:

$ file -i invoke-payload.json 
invoke-payload.json: text/plain; charset=us-ascii

如您所见，编码是 us-ascii 。

我还尝试发送嵌入命令的有效载荷。正如您在图片上看到的，我收到了相同的消息:



有任何想法吗？

对有效负载参数使用 fileb://(“文件二进制”)语法，这样您就不必通过 base64 运行它
...
--payload fileb://invoke-payload.json
