javascript - Firebase 功能使用“Firebase Serve”按预期工作，但在部署时抛出 ERROR 400

问题描述

我正在尝试使用 firebase 作为代理将数据从 API 提取到反应应用程序，以避免 CORS 限制。我可以在使用 Firebase Serve 时使用以下代码访问数据，但在部署时会抛出 400？感谢任何指导。

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

const app = express();
admin.initializeApp();


// @Route: /orders
// @Desc: Get Orders from cartrover API using Firebase as a proxy to enable CORS

app.get('/orders', (req, res) => {
    const user = req.body.username;
    const pass = req.body.password;
    
    cors(req, res, () => {
        axios
            .get('https://api.cartrover.com/v1/merchant/orders/list/shipped', {
                auth: {
                    username: user,
                    password: pass,
                },
            })

            .then((resp) => {
                res.send(resp.data);
            });
    });
});

exports.api = functions.https.onRequest(app);

当使用“Firebase Serve”在 localhost 上进行测试时，我得到一个 JSON 对象作为 API 的响应，正如预期的那样。当我部署 firebase 功能并发出相同的请求时，我收到以下错误：
