Python与Node.js之间实现通信的JSON数据接收发送

import json

# 定义 Python 对象
data = {
    'name': 'Alice',
    'age': 30,
    'city': 'New York'
}

# 转换为 JSON 字符串
json_string = json.dumps(data)
print(json_string)

import requests
# 定义要发送的数据
data = {
    'name': 'Bob',
    'age': 25,
    'city': 'San Francisco'
}
# 发送 POST 请求
response = requests.post('http://localhost:3000/data', json=data)
print(response.text)

const express = require('express');
const app = express();
app.use(express.json());
app.post('/data', (req, res) => {
    console.log(req.body);
    res.send('Received JSON data');
});
app.listen(3000, () => {
    console.log('Node.js server running on port 3000');
});

app.post('/data', (req, res) => {
    console.log(req.body);
    const responseData = {
        message: 'Data received successfully'
    };
    res.json(responseData);
});

response = requests.post('http://localhost:3000/data', json=data)
received_data = json.loads(response.text)
print(received_data['message'])

app.post('/data', (req, res) => {
    console.log(req.body);
    const responseData = {
        message: 'Data received successfully'
    };
    res.json(responseData);
});
