Firebase Cloud Function 在 Prod 中不起作用。出现错误

Question

转到 URL 时出现以下错误。Error: could not handle the request我似乎无法弄清楚为什么。我做错了什么？这是我的index.js文件。const functions = require('firebase-functions');var request = require('request');const admin = require('firebase-admin');admin.initializeApp();exports.addMessage = functions.https.onRequest(async (req, res) => {  const itemDescription = req.query.itemDescription;  const pageNumber = req.query.pageNumber;  const categoryId = req.query.categoryId;  const sortBy = req.query.sortBy;  const narrowSearch = req.query.narrowSearch;  cnst typeOfListing = req.query.typeOfListing;  const sellerExclusions = req.query.sellerExclusions;  const tagsExclusions = req.query.tagsExclusions;  const country = req.query.country;  const minPrice = req.query.minPrice;  const maxPrice = req.query.maxPrice;  const entriesPerPage = req.query.entriesPerPage;  const buyingFormat = req.query.buyingFormat;  let operationName = "";  let entriesPerPage2 = "";  let sortOrder = "";  let currentPage = "";  if (pageNumber !== null) {    currentPage = pageNumber;  } else {    currentPage = 1;  }  if (typeOfListing === 'active') {    operationName = "findItemsAdvanced";    entriesPerPage2 = 50;  } else {    operationName = "findCompletedItems";    if (buyingFormat === "Auction") {      entriesPerPage2 = 50;    } else {      entriesPerPage2 = 25;    }  }  let apicall = "https://URL?";  if (typeOfListing === "active") {    if (sortBy !== null) {       apicall += "&sortOrder=";       apicall += sortBy;       sortOrder = sortBy;    } else {      apicall += "&sortOrder=";      apicall += "BestMatch";      sortOrder = "BestMatch";    }  } else {    if (sortBy !== null) {       apicall += "&sortOrder=";       apicall += sortBy;       sortOrder = sortBy;    } else {      apicall += "&sortOrder=";      apicall += "EndTimeSoonest";      sortOrder = "EndTimeSoonest";    }  }  if (categoryId !== null) {    apicall += "&categoryId=";    apicall += categoryId;  }

Answer 1

在 Cloud Functions 中，您需要通过 Promises 管理异步方法调用。request本机支持回调接口但不返回承诺。

您应该使用另一个库，例如axios，如下所示：

exports.addMessage = functions.https.onRequest(async (req, res) => {

    try {

        // ...

        let apicall = "https://URL?";

        // ...

        apicall += "&itemFilter(0).name=SoldItemsOnly&itemFilter(0).value(0)=true";

        const response = await axios.get(apicall);

        // handle success

        // ...

        res.json({..});

    } catch (error) {

        res.status(500).send({ 'error': error });

    }

    

});

请注意，您可能需要使用“Blaze”定价计划。

事实上，免费的“Spark”计划“只允许向 Google 拥有的服务发出网络请求”。请参阅https://firebase.google.com/pricing/（将鼠标悬停在“云功能”标题后面的问号上）

另请注意，request已弃用。
