尝试通过 Google Cloud Workflows 复制同一存储桶中的数据会触发未找到异常

Question

我有一个非常简单的 Google Cloud 工作流程，即复制文件在同一个存储桶中：

main:
  steps:
    - list:
        call: googleapis.storage.v1.objects.list
        args:
          bucket: "**************"
          prefix: "xxx/extra_cost_commute.txt"
        result: listResult
    - log-files:
        call: sys.log
        args:
          data: ${listResult}
          severity: "INFO"
    - copy:
        call: googleapis.storage.v1.objects.copy
        args:
          sourceBucket: "**************"
          sourceObject: "xxx/extra_cost_commute.txt"
          destinationBucket: "**************"
          destinationObject: "yyy/new_extra_cost_commute.txt"
        result: copyResult
    - log-copy:
        call: sys.log
        args:
          data: ${copyResult}
          severity: "INFO"

list

步骤正确返回对象

xxx/extra_cost_commute.txt

，但

copy

步骤触发404未找到异常。

HTTP server responded with error code 404
in step "copy", routine "main", line: 15
{
  "body": "Not Found",
  "code": 404,
  "headers": {
    "Alt-Svc": "h3=\":443\"; ma=2592000,h3-29=\":443\"; ma=2592000",
    "Cache-Control": "no-cache, no-store, max-age=0, must-revalidate",
    "Content-Length": "9",
    "Content-Type": "text/html; charset=UTF-8",
    "Date": "Mon, 13 May 2024 19:42:39 GMT",
    "Expires": "Mon, 01 Jan 1990 00:00:00 GMT",
    "Pragma": "no-cache",
    "Server": "UploadServer",
    "Vary": "Origin, X-Origin",
    "X-Guploader-Uploadid": ""
  },
  "message": "HTTP server responded with error code 404",
  "tags": [
    "HttpError"
  ]
}

为什么？我究竟做错了什么？我迷路了。

注意：我测试了通过批处理连接器在

gcr.io/google.com/cloudsdktool/google-cloud-cli:alpine

中使用 gcloud 进行复制，并且工作正常。

由于您的 sourceObject 和 DestinationObject 包含

/

，您应该对路径进行 encode 。在工作流程中，您可以使用功能

text.url\_encode

。我尝试了您的工作流程，如果您将复制步骤更改为：

，它应该可以工作

copy:
    call: googleapis.storage.v1.objects.copy
    args:
      sourceBucket: "bucket-name"
      sourceObject: ${text.url_encode("xxx/extra_cost_commute.txt")}
      destinationBucket: "bucket-name"
      destinationObject: ${text.url_encode("yyy/new_extra_cost_commute.txt")}
    result: copyResult
