Google Cloud REST API 身份验证示例

Question

我需要从 Google Cloud Function 发出此请求：

POST https://compute.googleapis.com/compute/v1/projects/project-id/zones/zone/instanceGroupManagers/instance-group-name/resize?size=new-size

根据这些文档：https://cloud.google.com/compute/docs/instance-groups/creating-groups-of-managed-instances#api_2

我了解如何分配 JSON 服务帐户密钥并使用 googleapi 库来完成。但在这种情况下，我需要该功能做的就是这个单一的请求。所以，我想简单地用fetch() 来做。授权书怎么写？

const url = `https://compute.googleapis.com/compute/v1/projects/${projectId}/zones/${zone}/instanceGroupManagers/${instanceGroupName}/resize?size=${size}`

const response = await fetch(url, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  }
});
const responseJson = response.json();

您可以使用google auth library 获取正确的凭据并调用 API

const {GoogleAuth} = require('google-auth-library');

async function main() {
  const auth = new GoogleAuth({
    scopes: 'https://www.googleapis.com/auth/cloud-platform'
  });
  const client = await auth.getClient();

  const url = `https://compute.googleapis.com/compute/v1/projects/${projectId}/zones/${zone}/instanceGroupManagers/${instanceGroupName}/resize?size=${size}`

  const res = await client.request({ url: url,
  method: 'POST',
  headers: {
    'Content-Type': 'application/json'
  }
});
  console.log(res.data);
}

main().catch(console.error);
