javascript - 谷歌云抛出错误 : Could not load the default credentials in Nodejs

Question

我已将此服务帐户 key (my-key.json)文件存储在我的下载文件夹(ubuntu)中
然后我在我的控制台中运行这个命令export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json"根据
google cloud .现在我正在运行此代码，但它会引发错误。

const language = require('@google-cloud/language');

const quickstart = async function () {
  // Instantiates a client
  const client = new language.LanguageServiceClient();
 
  // The text to analyze
  const text = 'Hello, world!';
 
  const document = {
    content: text,
    type: 'PLAIN_TEXT',
  };
 
  // Detects the sentiment of the text
  const [result] = await client.analyzeSentiment({document: document});
  const sentiment = result.documentSentiment;
 
  console.log(`Text: ${text}`);
  console.log(`Sentiment score: ${sentiment.score}`);
  console.log(`Sentiment magnitude: ${sentiment.magnitude}`);
}


quickstart();

Answer 1

如果您使用 node <file-name>.js要初始化您的代码，您应该将命令更新为

GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json" node <file-name>.js

这将使 GOOGLE_APPLICATION_CREDENTIALS 在您的 Node 环境中可用。
但是，作为一个长期解决方案，我建议创建一个 .env文件和存储 GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/my-key.json" 在那个文件中。
然后使用 dotenv包在您的 js 开头以下列方式归档:

require('dotenv').config();
