如何对不同的API请求使用相同的属性

import axios from 'axios';

// 创建一个axios实例
const apiClient = axios.create({
  baseURL: 'https://api.example.com',
});

// 请求拦截器
apiClient.interceptors.request.use(config => {
  config.headers['Authorization'] = 'Bearer your_token';
  config.headers['X-Request-ID'] = generateRequestId();
  return config;
}, error => {
  return Promise.reject(error);
});

// 生成请求ID的函数
function generateRequestId() {
  return Math.random().toString(36).substr(2, 9);
}

// 使用apiClient发送请求
apiClient.get('/endpoint')
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

const express = require('express');
const app = express();

// 中间件：添加通用属性
app.use((req, res, next) => {
  req.headers['x-request-id'] = generateRequestId();
  next();
});

// 生成请求ID的函数
function generateRequestId() {
  return Math.random().toString(36).substr(2, 9);
}

// 路由处理
app.get('/endpoint', (req, res) => {
  res.json({ message: 'Hello World', requestId: req.headers['x-request-id'] });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

// config.js
module.exports = {
  commonHeaders: {
    'Authorization': 'Bearer your_token',
    'X-Request-ID': generateRequestId(),
  },
};

function generateRequestId() {
  return Math.random().toString(36).substr(2, 9);
}

// app.js
const express = require('express');
const config = require('./config');
const app = express();

app.use((req, res, next) => {
  Object.assign(req.headers, config.commonHeaders);
  next();
});

app.get('/endpoint', (req, res) => {
  res.json({ message: 'Hello World', requestId: req.headers['x-request-id'] });
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

apiClient.interceptors.request.use(config => {
  if (config.url !== '/special-endpoint') {
    config.headers['Authorization'] = 'Bearer your_token';
    config.headers['X-Request-ID'] = generateRequestId();
  }
  return config;
}, error => {
  return Promise.reject(error);
});
