无法使用 Java 部署管理器 SDK 更新 GCP 部署

Question

我正在尝试使用 Deployment Manager SDK for Java 编写一个应用程序来管理 GCP 部署。我能够成功列出部署，但无法更新部署，因为 SDK 会引发如下所示的异常。

com.google.api.client.googleapis.json.GoogleJsonResponseException: 404 Not Found
{
  "code" : 404,
  "errors" : [ {
    "domain" : "global",
    "message" : "The object 'projects/--redacted-project--/global/deployments' is not found.",
    "reason" : "notFound"
  } ],
  "message" : "The object 'projects/--redacted-project--/global/deployments' is not found."
}

        at com.google.api.client.googleapis.services.AbstractGoogleClientRequest.execute(AbstractGoogleClientRequest.java:469)

我的电话号码是：

val content = new Deployment().setTarget(target)

val updateResult = client.deployments().update(project, name, content)
          .setCreatePolicy("CREATE_OR_ACQUIRE")
          .setDeletePolicy("DELETE")
          .setPreview(false)
          .execute()

当我为 SDK 打开调试时，我看到以下交换：

所以它看起来像一个无效的 URL 或对象。

但是，如果我使用 gcloud CLI 工具对 --log-http 执行相同的操作，我会发现它访问的是完全相同的端点，但没有得到 404：

==== request start ====
uri: https://www.googleapis.com/deploymentmanager/v2/projects/--redacted-project--/global/deployments/--redacted-deployment--?alt=json&preview=False&createPolicy=CREATE_OR_ACQUIRE&deletePolicy=DELETE
method: PUT

不知道从这里去哪里。

Answer 1

进一步挖掘后，我注意到 PUT 请求中正文 JSON 中的字段不同。 gcloud CLI 发送 fingerprint、name 和 target，而 Java SDK 只发送 target。

隐藏在documentation for the request body 中，它说您需要为update 设置fingerprint 和一些其他方法。

我修改了我的代码以首先获取部署并在请求中包含fingerprint，它开始工作。

val content = new Deployment().setName(name).setFingerprint(fingerprint).setTarget(target)

val updateResult = client.deployments().update(project, name, content)
  .setCreatePolicy("CREATE_OR_ACQUIRE")
  .setDeletePolicy("DELETE")
  .setPreview(false)
  .execute()

在我看来 404 是错误的错误。 Google 应该返回 400，因为客户端未在请求中包含必填字段。

此外，SDK 会进行大量的前置条件检查以捕获无效请求，但不包括此一项。我已经通过 Google 向 opened an issue 提出建议。
