如何从React app在ExpressJS中执行函数?

server-side server express reactjs javascript

Ralph David Abernathy · 技术社区 · 6 年前

我的电脑里有以下功能 server.js

const express = require('express');

const someFunction = () => {
  setInterval(() => {
    console.log('ok');
  }, 1000);
};

app.listen(3001, () => someFunction());

如何从React组件运行此函数?就像我在React中有一个按钮组件:

<Button onClick={() => express.someFunction(...)}

var express = require('express')
var app = express()

const someFunction = () => {
  setInterval(() => {
    console.log('ok');
  }, 1000);
};


// respond with "hello world" when a GET request is made to the homepage
app.get('/', function (req, res) {
  someFunction()
  res.send('hello world')
})

然后你可以用 fetch api (或 axios fetch(someUrlThatInvokesFunctionGoesHere)
