快速路由器删除和 Firebase 云函数给出类型错误：无法读取未定义的属性'apply'

Question

我有一个Firebase Cloud函数，Firebase.json配置为：

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

我的灵感来自：本教程和这个旅游

路由器.js

const express = require('express');
const router = express.Router();
const cors = require('cors')
const firebaseHandler = require('../db/firebaseHandler')
router.use(cors())
router.delete('/:id', async (req, res, next) => {
try {
const id = req.params.id;
if (!id) throw new Error('id is blank');
await firebaseHandler.delete('worklogs', id);
res.json({
id
});
} catch(e) {
next(e);
}
});
module.exports = router;

火碱处理程序.js

const firebase = require('firebase');
const conf = require('../../../conf.json')
const config = {
apiKey: conf.firebaseConfig.apiKey,
authDomain: conf.firebaseConfig.authDomain,
databaseURL: conf.firebaseConfig.databaseURL,
projectId: conf.firebaseConfig.projectId,
schemaPath: conf.schemaPath
};
firebaseApp = firebase.initializeApp(config);
const db = firebaseApp.firestore();
exports.delete = async (type, id) => {
await database.collection(type).doc(id).delete(); 
}

在 url 中运行此内容时出现错误：http://localhost:5000/mycloudfunctionhere/api/documentidhere/

以下是错误的堆栈跟踪：

projectpathnode_modulesexpresslibrouterindex.js:635
return fn.apply(this, arguments);
TypeError: Cannot read property 'apply' of undefined
at Immediate.<anonymous> (projectpathnode_modulesexpresslibrouterindex.js:635:15)
at runCallback (timers.js:706:11)
at tryOnImmediate (timers.js:676:5)
at processImmediate (timers.js:658:5)

没有什么具体的，我已经尝试了多个示例，但我不断收到此错误。

提前感谢！

答案在于您不知道您无法在浏览器 url 中发出删除请求。一旦我做了一个 curl -x DELETE http://localhost:5000/mycloudfunctionhere/api/documentidhere/，它就起作用

了谢谢大家的回答！
