Firebase 托管 + 云功能

Question

难以部署我的功能以及托管。

问题是，我已经让它们在单独的分支上独立工作，但是..当尝试集成托管和我的云功能时，我的云功能似乎没有部署。我的终端没有收到任何错误，当我在 Firebase 控制台中单击“功能”时，它是默认屏幕，好像没有部署任何功能。

这是我用于托管 + 功能部署的 firebase.json。 托管在这里有效，但功能未部署

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      },
      {
        "source": "/api/v1/**",
        "function": "webApi"
      }
    ]
  },
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ],
    "source": "functions"
  }
}

这是我的 firebase.json，只有功能，没有托管

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "/api/v1/**",
        "function": "webApi"
      }
    ]
  },
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ],
    "source": "functions"
  }
}

这是我的函数/index.js

const functions = require('firebase-functions')
const admin = require('firebase-admin')
const serviceAccount = require('./serviceAccount.json')

const express = require('express')
const bodyParser = require('body-parser')

const _ = require('lodash')
const { getObjectValues } = require('./helper-functions.js')
const json2csv = require('json2csv').parse

admin.initializeApp({
  ...,
})
const db = admin.firestore()

const app = express()
const main = express()

main.use('/api/v1', app)
main.use(bodyParser.json())
exports.webApi = functions.https.onRequest(main)

app.get('/test', (request, response) => {
  response.send('API TEST')
})

app.get('/surveys', (request, response) => {
  const surveyCollection = db.collection('/surveys')
  return (
    surveyCollection
      .get()
      // eslint-disable-next-line promise/always-return
      .then(querySnapshot => {
        let surveyList = []
        querySnapshot.forEach(doc => {
          const survey = doc.data()
          surveyList.push(survey)
        })
        response.send(surveyList)
      })
  )
})

app.get('/surveys/:survey', (request, response) => {
  const surveyId = request.params.survey
  const userAnswers = db.collection(`/surveys/${surveyId}/submissions`)
  return (
    userAnswers
      .get()
      // eslint-disable-next-line promise/always-return
      .then(querySnapshot => {
        let surveySubmissions = []
        querySnapshot.forEach(doc => {
          const userSubmission = doc.data()
          surveySubmissions.push({
            ..._.mapValues(userSubmission.answers, getObjectValues), // format answers
            ...userSubmission.anonUser,
          })
        })
        response.setHeader('Content-disposition', 'attachment; filename=cna.json')
        response.set('Content-Type', 'application/json')
        response.status(200).send(surveySubmissions)
      })
      .catch(error => {
        console.log(error)
      })
  )
})

托管+功能分支，我输入'firebase deploy'

terminal output:

    i  deploying functions, hosting
Running command: npm --prefix "$RESOURCE_DIR" run lint

> functions@ lint \surveyplus-cna\functions
> eslint .

仅云端功能分支 firebase deploy输出

Answer 1

您的 Cloud Functions 已正确部署，因为我可以直接调用 /api/v1/test 路由就好了（在撰写本文时）。

但是，在您的 firebase.json 文件中，您的重写顺序不正确，如 docs 中突出显示的那样：

重要提示：在rewrites 属性内，Hosting 响应将遵守由 first source glob 指定的规则，该规则捕获请求的路径。

{
  "hosting": {
    "public": "build",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "/api/v1/**",
        "function": "webApi"
      },
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  },
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint"
    ],
    "source": "functions"
  }
}

因此，不是发送/api/v1/test 调用由您的云函数处理，而是错误地发送到您的 React 应用程序。交换订单应该可以解决这个问题。

另外注意，如果您打算将所有调用格式化并解析为 JSON，则应重新排序 main.use 调用。我也会使用 express Router 而不是完整的 express() 实例。

const main = express(); // full express instance
const app = express.Router(); // "child" express instance

main.use(bodyParser.json()) // parse body as json, then hand over to app
main.use('/api/v1', app)
