Question

我正在尝试实现google automl api https://cloud.google.com/automl-tables/docs/predict

api文档说我需要以以下格式发布数据

{
  "payload": {
    "row": {
     "values": [value1, value2,...]
         }
      }
}

但是当我以相同格式发布数据时，出现以下错误。

{
  "error": {
    "code": 400,
    "message": "Invalid JSON payload received. Unknown name \"row\" at 'payload': Cannot find field.",
    "status": "INVALID_ARGUMENT",
    "details": [
      {
    "@type": "type.googleapis.com/google.rpc.BadRequest",
    "fieldViolations": [
      {
        "field": "payload",
        "description": "Invalid JSON payload received. Unknown name \"row\" at 'payload': Cannot find field."
      }
    ]
      }
    ]
  }
}

这是我的卷曲要求

curl --location --request POST 'https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/TBLID:predict' \
--header 'Content-Type: application/json; charset=utf-8;' \
--header 'Accept-Charset: utf-8' \
--header 'Authorization: Bearer token here' \
--data-raw '{
 "payload": {
"row": {
  "values": [
    "",
    "4.900000",
    ""
  ]
}
 }
}'

我不确定导致此错误的原因。任何人都可以帮助解决这个问题

Answer 1

我有一个带有AutoML表的项目，这是发送的示例预测请求，该请求可以正常运行并返回结果而不会出错：

{
  "payload": {
    "row": {
      "values": [
        "2",
        "test text",
        "test text",
        "21",
        "0",
        "0",
        "test text",
        "10",
        "",
        "S"
      ]
    }
  }
}

如果不确定如何提交数据或遇到错误，请转到控制台中的项目和AutoML Tables模型，然后单击“测试和使用”。然后，按照getting an online prediction from console的指示进行操作。请注意“ JSON代码视图”，它将为您提供准确的输入并让您也测试您的JSON输入。

为了测试，我提交了以下curl请求（更改了一些识别字符）

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
https://automl.googleapis.com/v1beta1/projects/this-isnt-a-real-project-id/locations/us-central1/models/TBL123451234512345:predict

我发送请求的目录中的我的request.json文件是：

{
    "payload": {
      "row": {
        "values": [
          "yes",
          "-1",
          "primary",
          "jul",
          "51",
          "0",
          "yes",
          "no",
          "88",
          "cellular",
          "blue-collar",
          "unknown",
          "10",
          "620",
          "married"
        ]
      }
    }
  }

答复为：

{
  "payload": [
    {
      "tables": {
        "score": 0.9999906,
        "value": "no"
      }
    },
    {
      "tables": {
        "score": 9.42341e-06,
        "value": "yes"
      }
    }
  ]
}

我还在下面的邮递员中成功地重复了同样的请求：

curl --location --request POST 'https://automl.googleapis.com/v1beta1/projects/this-isnt-a-real-project-id/locations/us-central1/models/TBL123451234512345:predict' \
--header 'Accept-Charset: utf-8' \
--header 'Authorization: Bearer abcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcdabcd' \
--header 'Content-Type: application/json' \
--data-raw '{
    "payload": {
      "row": {
        "values": [
          "yes",
          "-1",
          "primary",
          "jul",
          "51",
          "0",
          "yes",
          "no",
          "88",
          "cellular",
          "blue-collar",
          "unknown",
          "10",
          "620",
          "married"
        ]
      }
    }
  }'

Answer 2

我复制了Quickstart，并成功执行了一些curl请求，您的问题似乎与json请求的格式有关；因此，我建议进行以下测试：

从json中删除换行符，然后再次发出请求：

curl --location --request POST 'https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/TBLID:predict' \
--header 'Content-Type: application/json; charset=utf-8;' \
--header 'Accept-Charset: utf-8' \
--header 'Authorization: Bearer token-here' \
--data-raw '{ "payload": { "row": { "values": [ "", "4.900000", "" ] } } }'

将json保存在文件中，然后再次发出请求：

curl --location --request POST 'https://automl.googleapis.com/v1/projects/project-id/locations/us-central1/models/TBLID:predict' \
--header 'Content-Type: application/json; charset=utf-8;' \
--header 'Accept-Charset: utf-8' \
--header 'Authorization: Bearer token-here' \
-d @request.json

如果执行这些操作后仍然遇到问题，建议您与GCP support联系，以便他们可以在您的项目中分析您的问题。
