express模版

express服务端

//用node开启服务
const express = require('express')
const app = express()
//const sum = require("./sum")  # 方法单独封装成文件
var bodyParser = require("body-parser")
app.use(bodyParser())
//执行的方法
function sum (a,b){
    return a+b
}
app.post('/get_data',function (req, res) {
    let result = req.body
    console.log('data:',result)
    let a = parseInt(result.a)
    let b = parseInt(result.b)
    console.log('a:',a)
    console.log('b:',b)
    result = sum(a,b)
    console.log('result:',result)
    res.send(result.toString())   //返回数据
})
app.listen(3000,() => {
    console.log('开启服务，端口3000')
})

express客户端

import requests
url = "http://127.0.0.1:3000/get_data"
data = {
    "a": 1,
    "b": 2
}
req = requests.post(url,data)
print(req.text)

express模版

const express = require('express');
const bodyParser = require('body-parser');
const app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.post('/geturl', function (req, res) {
    let { url } = req.body;
    let new_url = getUrl(url);
    console.log('result:\n',new_url);
    res.send(new_url);
});
app.post('/getsign', function (req, res) {
    let { url } = req.body;
    let sign = getSign(url);
    console.log('result:\n',sign);
    res.send(sign);
});
const server = app.listen(3000, function () {
    console.log(
        "node服务启动，监听地址为: http://127.0.0.1:3000"
    )
});
