Google API节点库-缺少Cloudiot [英] Google apis node library - cloudiot missing

问题描述

我一直在寻找一种使用Google Cloud功能管理Cloud IOT核心设备的方法. 经过数天的测试，我不知道如何将设备添加到注册表中.

I was looking for a way to manage cloud iot core devices with google cloud functions. After days of testing I can't figure out how I can add a device to a registry.

我尝试使用npm在我的PC上安装googleapis模块，但是在github上的apis目录中找不到cloudiot核心(已安装的软件包的版本是22.2.0，但是在github上的版本是22.3.0 ).

I have tried to install googleapis module on my pc with npm but I can't find cloudiot core in the apis directory while there is on github (the version of the installed package is 22.2.0 but on github is 22.3.0).

有什么想法吗?如何安装最新版本?

Any ideas ? How can I install the latest version ?

更新

目前看来，当您未从发现文档中显式加载API时，NodeJS客户端库就出现了IoT问题.

It appears that currently, when you don't explicitly load the API from the discovery document, the NodeJS client library is having issues with IoT.

要暂时解决此问题，请执行以下操作初始化您的API客户端:

To work around this for now, do the following to initialize your API client:

const serviceAccountJson = `/home/class/iot_creds.json`;
const API_VERSION = 'v1';
const DISCOVERY_API = 'https://cloudiot.googleapis.com/$discovery/rest';
function getClient (serviceAccountJson, cb) {
  const serviceAccount = JSON.parse(fs.readFileSync(serviceAccountJson));
  const jwtAccess = new google.auth.JWT();
  jwtAccess.fromJSON(serviceAccount);
  // Note that if you require additional scopes, they should be specified as a
  // string, separated by spaces.
  jwtAccess.scopes = 'https://www.googleapis.com/auth/cloud-platform';
  // Set the default authentication to the above JWT access.
  google.options({ auth: jwtAccess });
  const discoveryUrl = `${DISCOVERY_API}?version=${API_VERSION}`;
  google.discoverAPI(discoveryUrl, {}, (err, client) => {
    if (err) {
      console.log('Error during API discovery', err);
      return undefined;
    }
    cb(client);
  });
}

原始

NodeJS管理示例当前使用的是Google API客户端(例如 package.json 中的"googleapis": "20.1.0")库，而不是单独的库.

The NodeJS management sample currently uses the Google API client (e.g. "googleapis": "20.1.0" in package.json) library and not a separate library.

如果还没有，请尝试按照示例自述文件中的说明在本地运行该示例:

If you haven't already, try running the sample locally as described in the sample readme:

git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples
cd nodejs-docs-samples/iot/manager
npm install
node manager.js

如果该示例不在本地运行，请告知我们节点版本(node --version)和已安装的模块版本( package.lock 或npm ls的输出).

If the sample doesn't work locally, please let us know the node version (node --version) and installed modules versions (output of package.lock or npm ls).

如果示例在本地运行(运行npm install之后)，则问题在于如何从Cloud函数后端执行示例.

If the sample works locally for you (after running npm install) then the issue is with how the sample is being executed from the Cloud functions backend.
