Firebase Cloud函数如何处理HTTP发布方法? [英] How Firebase Cloud functions handle HTTP post method?

问题描述

我已经创建了Firebase Cloud Functions应用程序， 我用https.onRequest创建了函数. 并使用req.body获取数据，但是那里没有数据.

I have created Firebase Cloud Functions app, I created function with https.onRequest. and get data with req.body but there is not data there.

Firebase Cloud Functions可以处理HTTP POST方法吗?

Can Firebase Cloud Functions can handle HTTP POST method?

这是我的示例代码:-

var functions = require('firebase-functions');

exports.testPost = functions.https.onRequest((req, res) => {
    console.log(req.body);
});

我由邮递员使用POST方法进行了测试，但未在Firebase日志中显示结果.

I tested by postman with POST method but didn't show result in Firebase log.

推荐答案

在Firebase上构建的功能还可以使用Express.js路由器来处理GET/POST/PUT/DELETE等... Google完全支持，并且推荐的实现这些类型功能的方式.

Functions built on Firebase can also use Express.js routers for handling GET/POST/PUT/DELETE, etc... is fully supported by Google, and is the recommended way to implement these types of functions.

这是一个基于Node.js构建的工作示例

Here's a working example built on Node.js

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

// Automatically allow cross-origin requests
app.use(cors({ origin: true }));

app.get('/hello', (req, res) => {
  res.end("Received GET request!");  
});

app.post('/hello', (req, res) => {
  res.end("Received POST request!");  
});

// Expose Express API as a single Cloud Function:
exports.widgets = functions.https.onRequest(app);

然后，运行firebase deploy，这将编译您的代码并创建新的窗口小部件"功能.注意:您可以将小部件重命名为所需的任何名称.最终，它将生成用于调用该函数的URL.

Then, run firebase deploy, and that should compile your code and create the new "widgets" function. Note: You can rename widgets to anything you want. Ultimately, it will generate a URL for calling the function.
