创建和管理池

本页面介绍了如何创建和管理 Live Stream API 池。池是在每个区域中为每个 Google Cloud 项目分配的一个处理单元，在指定区域中的所有渠道之间共享。池用于保护 VPC Service Controls 边界内的输入端点。如需了解详情，请参阅使用 VPC Service Controls 来保护流水线。

设置您的 Google Cloud 项目和身份验证

如果您尚未创建 Google Cloud 项目和凭据，请参阅准备工作。

创建池

当您首次在某个位置创建输入端点时，系统会自动为该位置创建默认池。

获取池详细信息

如需获取池的详细信息，请使用 projects.locations.pools.get 方法。

REST

在使用任何请求数据之前，请先进行以下替换：

PROJECT_NUMBER：您的 Google Cloud 项目编号；这可以在 IAM 设置页面的项目编号字段中找到
LOCATION：使用您已在其中创建输入的其中一个受支持区域

如需发送您的请求，请展开以下选项之一：

curl（Linux、macOS 或 Cloud Shell）

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI，或者使用了 Cloud Shell，这会使您自动登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/pools/default"

PowerShell (Windows)

注意：以下命令假定您已使用您的用户账号通过运行 gcloud init 或 gcloud auth login 登录 gcloud CLI。您可以运行 gcloud auth list 来检查当前活跃的账号。

执行以下命令：

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method GET `
    -Headers $headers `
    -Uri "https://livestream.googleapis.com/v1/projects/PROJECT_NUMBER/locations/LOCATION/pools/default" | Select-Object -Expand Content

您应该收到类似以下内容的 JSON 响应：
