如何使用托管轮播在Firebase托管和云功能之间进行连接 [英] How can I using hosting rewirtes to connect between firebase hosting and cloud functions

问题描述

用于更具体描述的新内容

我正在尝试使用express和firebase函数进行高级路由.

I'm trying to use express and firebase function for advanced routing.

但是当我尝试获取Firebase云功能时出现此错误

But I've got this error when I trying to get my firebase cloud function

/functions/index.js

/functions/index.js

const functions = require("firebase-functions")
const admin = require("firebase-admin")
const cors = require("cors")
const express = require("express")
const apiRoute = require("./api")

// admin.initializeApp(functions.config().firebase)

const app = express()
app.use(cors)

app.use("/api", apiRoute)

exports.api = functions.https.onRequest(apiRoute)

/functions/api.js

/functions/api.js

const router = require("express").Router()

router.get("/data", (req, res) => {
  res.send(`this is data`)
})

module.exports = router

有人可以给我一个解决这个问题的线索吗?

Could anyone give me a clue to solve this problem?

以前的内容

我正在尝试将我的node(带有express)项目转换为与Firebase兼容的项目.

I'm trying to convert my node(with express) project into Firebase compatible one.

我将我的API端点添加到 /functions/index.js

I add my API endpoint in /functions/index.js

const apiRoute = require("./routes/api")
exports.api = functions.https.onRequest(apiRoute)

在我的api.js中

router.get("/", (req, res) => {
  res.send("api is running on")
})

router.get("/sentences", (req, res) => {
  res.send("hi")
})

所以，我的期望是当我打电话给localhost:5000/api或localhost:5000/api/sentences时，我可以得到响应，但是那是行不通的.

So, my expectation was when I call localhost:5000/api or localhost:5000/api/sentences, I could get a response, but it doesn't work.

为此，我尝试使用.onCall提交我的云函数，而不是使用.onRequest.

For that, I tried .onCall to submit my cloud function rather than using .onRequest.

但我致电functions.httpsCallable("endpoint")时，仅接受POST请求.

But only POST request was accepted when I call functions.httpsCallable("endpoint").

因此，我尝试使用onRequest并在firebase.json中托管中进行重写

So, I tried to use onRequest and rewrites in hosting in firebase.json

"hosting": {
    "public": "public",
    "ignore": ["firebase.json", "**/.*", "**/node_modules/**"],
    "rewrites": [
      {
        "source": "/api/**",
        "function": "api"
      }
    ]
  },

但是，我只是遇到了这个错误:

But, I just got this error:

TypeError:无法在/Users/fredriccliver/Projects/Speech/functions/node_modules/express/lib/router/index.js:635:15下读取未定义的属性应用"

TypeError: Cannot read property 'apply' of undefined at /Users/fredriccliver/Projects/Speech/functions/node_modules/express/lib/router/index.js:635:15 at next

我应该如何从前端javascript调用函数?

How should I take the way to call my functions from frontend javascript?

推荐答案

检查了YouTube剪辑并尝试了更多内容后，我解决了问题.

I resolved after check a youtube clip and trying some more.

总结在我的中等职位上. https ://medium.com/@fredriccliver/how-to-use-an-express-router-within-the-cloud-function-developing-environment-cb64face4043

summarised on my medium post. https://medium.com/@fredriccliver/how-to-use-an-express-router-within-the-cloud-function-developing-environment-cb64face4043

functions/index.js

const functions = require("firebase-functions")
const express = require("express")
const app = express()

// my routings
const apiRoute = require("./api")

// add routes to the express app.
app.use("/api", apiRoute)

exports.api = functions.https.onRequest(app)

functions/api.js

const router = require("express").Router()

router.get("/api/user/data", (req, res) => {
  res.send(`this is /api/user/data`)
})

router.get("/api/data", (req, res) => {
  res.send(`this is /api/data`)
})

router.get("/api/api", (req, res) => {
  res.send(`here is /api/api`)
})

router.get("/api", (req, res) => {
  res.send(`here is /api`)
})

router.get("/data", (req, res) => {
  res.send(`here is /data`)
})

router.get("/", (req, res) => {
  res.send(`here is /`)
})

module.exports = router

/firebase.json

{
  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [{
      "source": "/api/**",
      "function": "api"
    }]
  }
}

所以，我可以接近所有端点

So, I could approach all endpoints
