Javascript React应用程序、http代理中间件和axios代理到后端服务器（生产和开发）

我想要的是在生产和开发两方面都做代理工作。 每当我试图发出

POST

请求时，我都会收到

您需要启用JavaScript才能运行此应用程序

代理服务器似乎不起作用

后端url示例

https://backend-example.com/api/create

样本请求功能

export const create = async () => {
  try {
    const res = await api.post(`/api/create`)
    console.log(res)
    return res.data
  } catch (e) {
    console.error(e.message)
  }
}

api.ts

import axios from 'axios'

const api = axios.create({
  headers: {
    'Content-Type': 'application/json',
  },
})
api.interceptors.request.use(
  (config) => {
    const token = localStorage.getItem('token')
    if (token) {
      config.headers['Authorization'] = `Bearer ${token}`
    }
    return config
  },
  (error) => Promise.reject(error)
)
export default api

import { createProxyMiddleware } from 'http-proxy-middleware'
const BACKEND_URL = process.env.REACT_APP_BACKEND_ENDPOINT as string // https://backend-example.com

export default function (app: {
  use: (arg0: string, arg1: import('http-proxy-middleware').RequestHandler) => void
}) {
  app.use(
    '/api',
    createProxyMiddleware({
      target: BACKEND_URL,
      pathRewrite: { '^/api': '/' },
      changeOrigin: true,
    })
  )
}

proxy.ts

import axios from 'axios'

const api = axios.create({
  headers: {
    'Content-Type': 'application/json',
  },
})
api.interceptors.request.use(
  (config) => {
    const token = localStorage.getItem('token')
    if (token) {
      config.headers['Authorization'] = `Bearer ${token}`
    }
    return config
  },
  (error) => Promise.reject(error)
)
export default api

import { createProxyMiddleware } from 'http-proxy-middleware'
const BACKEND_URL = process.env.REACT_APP_BACKEND_ENDPOINT as string // https://backend-example.com

export default function (app: {
  use: (arg0: string, arg1: import('http-proxy-middleware').RequestHandler) => void
}) {
  app.use(
    '/api',
    createProxyMiddleware({
      target: BACKEND_URL,
      pathRewrite: { '^/api': '/' },
      changeOrigin: true,
    })
  )
}

我甚至为此尝试了

axios

const api = axios.create({
  headers: {
    'Content-Type': 'application/json',
  },
  proxy: {
     host:'https://backend-example.com',
     port: 80,
  }
})

谢谢：）
