为什么 Firebase 不是运行我的函数文件夹（对于节点应用程序）？

Question

我正在尝试在 firebase 上托管节点应用程序

问题是当我运行一个非常基本的时间戳函数时它总是超时。

这是 firebase.json 文件：

{
  "database": {
    "rules": "database.rules.json"
  },
  "hosting": {
    "public": "public",
    "rewrites": [{
      "source": "/timestamp",
      "function": "app"
    }],
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ]
  }
}

这是函数文件夹中的 package.json 文件：

{
  "name": "functions",
  "description": "Cloud Functions for Firebase",
  "scripts": {
    "serve": "firebase emulators:start --only functions",
    "shell": "firebase functions:shell",
    "start": "npm run shell",
    "deploy": "firebase deploy --only functions",
    "logs": "firebase functions:log"
  },
  "engines": {
    "node": "10"
  },
  "main": "index.js",
  "dependencies": {
    "dotenv": "^8.2.0",
    "express": "^4.17.1",
    "firebase-admin": "^8.10.0",
    "firebase-functions": "^3.6.1",
    "jquery": "^3.5.1",
    "node": "^14.8.0",
    "nodemailer": "^6.4.11",
    "nodemailer-mailgun-transport": "^2.0.0",
    "nodemon": "^2.0.4"
  },
  "devDependencies": {
    "firebase-functions-test": "^0.2.0"
  },
  "private": true
}

这里是函数文件夹中的index.js：

const functions = require('firebase-functions');
const express = require('express');

const app = express();
app.get('/timestamp', (request, response)=>{
    response.send(`${Date.now()}`);
});

// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
exports.helloWorld = functions.https.onRequest(app);

这是我在本地运行 firebase 时的终端日志：

Answer 1

我想不通，但是，你的问题很完美，我可以很容易地在我这边复制它。试了几次，我找到了，但这是一个很小的错误，但是这样的错误是最难发现的。

firebase.json 中 hosting 中提供的代码函数与从 index.js 中导出的函数不同。所以有2个解决方案：

在 firebase.json 托管中应该有 "function": "helloWorld"

或

在index.js中应该有：exports.app = functions.https.onRequest(app);

我这边都很好用！

Answer 2

就我而言，我转到了 firebase.json 文件，我最初将其作为：

{
    "database": {
        "rules": "database.rules.json"
    }
}

我改成了：

{
  "hosting": {
    "public": "public",
    "rewrites": [{
      "source": "**",
      "function": "app"
    }]
  }
}
