node.js - 如何将 api key 传递给 Google Cloud Vision NodeJS API

Question

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

我可以找到 NodeJS Cloud Vision API 的所有示例要么使用从环境变量获取的凭据，要么使用 JSON 凭据文件，但我想使用 api key 调用 API。我该怎么做？

Answer 1

我也有同样的问题需要解决。经过一番挖掘，我得到了一个在单枪射击中有效的解决方案。

确保安装了所需的 Node 模块:

npm install @google-cloud/vision



const vision = require('@google-cloud/vision');
const {GoogleAuth, grpc} = require('google-gax');

const apiKey = '**********';

function getApiKeyCredentials() {
  const sslCreds = grpc.credentials.createSsl();
  const googleAuth = new GoogleAuth();
  const authClient = googleAuth.fromAPIKey(apiKey);
  const credentials = grpc.credentials.combineChannelCredentials(
    sslCreds,
    grpc.credentials.createFromGoogleCredential(authClient)
  );
  return credentials;
}


async function main(fileName) {
  const sslCreds = getApiKeyCredentials();
  const client = new vision.ImageAnnotatorClient({sslCreds});
  const [result] = await client.faceDetection(fileName); 
  const faces = result.faceAnnotations;

  //your custom code 

}
