如何从Firebase Cloud Function执行Axios请求 [英] How to do Axios request from Firebase Cloud Function

问题描述

我已经尝试过在Firebase Cloud Function中执行以下操作来发出Axios请求，但是它没有用.

I've tried the following in Firebase Cloud Function to do an Axios request but it didn't work.

    const functions = require('firebase-functions');
    const axios = require('axios');
    const cors = require('cors')({ origin: true });

exports.checkIP = functions.https.onRequest((req, res) => {
    cors(req, res, () => {
        if( req.method !== "GET" ) {
            return res.status(401).json({
                message: "Not allowed"
            });
        }

        return axios.get('https://api.ipify.org?format=json')
        .then(data => {
            console.log(data)
            res.status(200).json({
                message: data.ip
            })
        })
        .catch(err => {
            res.status(500).json({
                error: err
            })
        })

    })
})

我也用Google搜索了很多有关如何将Axios与Cloud Functions一起使用的示例，但没有找到.上面的代码未返回任何内容.

I've also googled a lot for seeing some example of how to use Axios with Cloud Functions but found none. The above code is not returning anything.

任何人都可以帮忙吗?

附言::我已经在Firebase帐户中添加了结算明细，而不是使用免费的Spark计划，而是使用了Blaze计划.

P.S.: I've already added billing details in my Firebase account and not using the free Spark plan, rather using Blaze plan.

我终于可以使用request-promise节点程序包来执行此操作，但是仍然不知道如何使用axios来执行此操作.无论我怎么尝试，axios在Firebase云功能中均不起作用.这就是我所做的:

I've finally able to do this using the request-promise node package but still no idea about how to do it with axios. As no matter what I try, axios doesn't work in Firebase cloud functions. This is what I did:

npm i --save cors request request-promise

然后这是我运行的代码: https://gist.github.com/isaumya/0081a9318e4f7723e0123f4def744a0e

Then this is the code I run: https://gist.github.com/isaumya/0081a9318e4f7723e0123f4def744a0e

也许会帮助某人.如果有人知道如何使用Axios进行操作，请在下面回答.

Maybe it will help someone. If anyone knows how to do it with Axios please answer below.

推荐答案

我将data.ip更改为response.data.ip，并在两条res.status(...行之前添加了return，并且当我使用Axios时，已部署的云功能对我有用试试吧.

I changed data.ip to response.data.ip and added return before the two res.status(... lines and the deployed cloud function works for me using Axios when I try it.

我的代码是

const functions = require('firebase-functions');
const axios = require('axios');
const cors = require('cors')({ origin: true });

exports.checkIP = functions.https.onRequest((req, res) => {
  cors(req, res, () => {
    if (req.method !== "GET") {
      return res.status(401).json({
        message: "Not allowed"
      });
    }

    return axios.get('https://api.ipify.org?format=json')
      .then(response => {
        console.log(response.data);
        return res.status(200).json({
          message: response.data.ip
        })
      })
      .catch(err => {
        return res.status(500).json({
          error: err
        })
      })

  })
});

当我调用该函数时，我会得到如下回复 { 消息":"127.168.121.130" }

When I invoke the function I get back a reply like { "message": "127.168.121.130" }
