【问题描述】：

我的 index.js 如下所示

import * as functions from 'firebase-functions';
import * as rp from "request-promise-native";
import * as btoa from "btoa";
import * as admin from 'firebase-admin';
import * as SendGrid from '@sendgrid/mail';
admin.initializeApp(functions.config().firebase)

export const dialog_handler = functions.https.onRequest(async (request, response) => {
    console.log("in dialog_handler request payload is:" + request.body.payload)
    const reqParams = JSON.parse(request.body.payload)

    const callbackId = reqParams.callback_id
    console.log(":::::::::::::::Callback Id:" + callbackId)
    const submission = reqParams.submission
    console.log(submission )
    let payload = {}

    if(callbackId === 'send_feedback'){
        await admin.database().ref("feedback").push(submission);
        payload = { "attachments": [
            {
                "fallback": "Feedback submitted",
                "title": "Feedback submitted. We will get back to you as soon as possible."
            }]
       }

    }
}

上面的实际代码无关紧要。主要是在有效载荷下方，这对我来说是一种可重用的代码。我怎样才能将它从 index.ts 中移出并仅引用它并保持我的 index.tx 小。

 payload = { "attachments": [
                {
                    "fallback": "Feedback submitted",
                    "title": "Feedback submitted. We will get back to you as soon as possible."
                }]
           }

【解决方案1】：

这实际上与 Cloud Functions 没有任何关系，而是与 TypeScript 模块语法和解析有关。

您可以有一个相邻的文件payload.ts，如下所示：

export const payload = { "attachments": [{
                "fallback": "Feedback submitted",
                "title": "Feedback submitted. We will get back to you as soon as possible."
            }]
       }

然后你可以从另一个文件中获取它的值：

import { payload } from "./payload"

您可能想阅读module resolution in TypeScript。
