我的客户希望在每次axios调用时都传递一个自签名证书。我如何才能做到这一点？

const https = require('https');
const axios = require('axios');
const fs = require('fs');

// 读取自签名证书
const cert = fs.readFileSync('path/to/certificate.pem');
const key = fs.readFileSync('path/to/private-key.pem');

// 创建https代理
const agent = new https.Agent({
  cert: cert,
  key: key
});

// 发送axios请求时添加https代理
axios.get('https://example.com', { httpsAgent: agent })
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });
