Question

每当将文档添加到Cloud Firestore数据库时，我就使用Cloud Functions for Firebase触发API调用。我基本上只是在抓取新创建的文档的photoReference值，并尝试获取google place photo api的URL值（而不是照片本身）并将其存储在新字段imageUrl中。

我隔离了该问题，当我在本地触发云功能时，它可以工作，但是当我部署它时，它会向我返回读取错误（见下文）。

exports.googlePlaceImageApiTest2 = functions.https.onRequest(async (req, res) => {
  // target i want to receive: "https://lh3.googleusercontent.com/p/AF1QipPIseBGCsj9tkRu3LLmjLwWMR7ARrVekgZp8rQ8";
  // helper method
  const handleErrors = response => {
    if (!response.ok) {
      throw Error(response.statusText);
    }
    return response;
  };
  // START API CALL
  console.log("starting API call");
  const apiKey = "xxxxxx";
  const photoReference = "CmRaAAAAEEo1d6LnuIvTCKlxy_NbyJ48Mg0dIzoRhGQ_J7NgbVGyxecEWMFJqdOjSQxpTATBebjflJyvSJab787G54kyVsnBF1b73IMLJSROH50KMpzMGZC1hzHNxzszlm3D6Ow5EhCivI6d91eRP3--M7qYbg8hGhQzVqmiTXHqKN7IqzYnQedaILWJpQ";
  const url = `https://maps.googleapis.com/maps/api/place/photo?key=${apiKey}&photoreference=${photoReference}&maxwidth=400`;

  let fetch = require("node-fetch");
  fetch(url)
  .then(handleErrors)
  .then(response => {
    const target = response.url;
    console.log(">>>>>FINAL URL: ", target);
    res.status(200).send(target).end();
    return 0;
  }).catch(error => {
    console.log(">>>>>ERROR!!!");
    console.log(error);
    res.status(500).send("error").end();
    return 0;
  });
});

这就是我在Firebase控制台中检查日志时得到的内容

尝试调用Google Places（照片）API时，GoogleCloudFunction抛出FetchError错误
