Question

登录到Google Console并打开云外壳时，我有一个（Bash）外壳，然后使用“三个点”菜单将文件上传到该实例：

如何使用本地命令行（例如，从笔记本电脑上运行的操作系统）执行此操作？我想我需要正在运行的实例的名称，如何找到它？

要获取当前Cloud Shell实例的名称，您可以调用Cloud Shell REST API。该端点将返回描述实例的JSON：

https://cloud.google.com/shell/docs/reference/rest/v1alpha1/users.environments/get

返回的JSON看起来像这样：

{
  "name": "users/john.smith@example.com/environments/default",
  "id": "default",
  "dockerImage": "gcr.io/cloudshell-images/cloudshell:latest",
  "state": "RUNNING",
  "sshUsername": "john_smith,
  "sshHost": "devshell-vm-5ee6f5d4-3c46-4fee-8865-dc0978b5af98.cloudshell.dev",
  "sshPort": 6000,
  "publicKeys": [
    {
      "name": "users/me/environments/default/publicKeys/8b4afb8d-5fd9-1234-85d9-9527393ea7ca",
      "format": "SSH_RSA",
      "key": "<removed>"
    },
    {
      "name": "users/me/environments/default/publicKeys/0a580367-fd88-56ae-dc4e-5295ee29784e",
      "format": "SSH_RSA",
      "key": "<removed>"
    }
  ]
}

我已经发布了用Go语言编写的完整程序，该程序可与Google Cloud Shell交互。这包括执行远程命令，上传文件，下载文件以及通过SSH连接启动Putty。

以下示例显示了如何调用Cloud Shell REST API以获取实例信息：

    "encoding/json"
    "fmt"
    "os"
    "time"
    "github.com/kirinlabs/HttpRequest"
)

“初始” GCP云外壳实例的名称是什么？
