套接字在使用 axios.get 时挂断，但在使用 https.get 时不挂断 [英] Socket hang up when using axios.get, but not when using https.get

问题描述

据我所知，我正在使用两种不同的方法做同样的事情:

To the best of my knowledge, I am doing the same thing using 2 different approaches:

const https = require("https");
const axios = require("axios");

let httpsAgent = new https.Agent({rejectUnauthorized: false});

axios.get(`https://${hostname}:${port}${path}`, {httpsAgent})
    .then((data) => { console.log("axios success: " + data.substr(0, 100)); })
    .catch((error) => { console.log("axios error: " + error); });

let data = "";
https.get({ hostname, path, port, agent: httpsAgent },
    (response) => {
        response.on("data", (chunk) => { data += chunk; });
        response.on("end", () => { console.log("https success: " + data.substr(0, 100)); });
    })
    .on("error", (error) => { console.log("https error: " + error); });

当我运行这段代码时，我得到了两种不同的结果:

When I run this code, i get 2 different outcomes:

PS C:Usersme> .
ode
ode.exe .generate-test-data.js
axios error: Error: socket hang up
https success: [{"cool":"data"...

这里发生了什么?我有一种感觉，它与异步性有关，但不太确定如何...有人可以提示我这两种行为如何/为什么不同吗?

What is going on here? I have a feeling it has to do with asynchronicity, but not quite sure how... Can somebody give me a hint as to how/why these 2 behaviors are different?

推荐答案

ARGH!

在 axios 源代码中挖掘后，我发现了这一点:

After digging around in the axios source, I found this:

if (!proxy) {
  var proxyEnv = protocol.slice(0, -1) + '_proxy';
  var proxyUrl = process.env[proxyEnv] || process.env[proxyEnv.toUpperCase()];
  if (proxyUrl) {
    var parsedProxyUrl = url.parse(proxyUrl);
    proxy = {
      host: parsedProxyUrl.hostname,
      port: parsedProxyUrl.port
    };

    if (parsedProxyUrl.auth) {
      var proxyUrlAuth = parsedProxyUrl.auth.split(':');
      proxy.auth = {
        username: proxyUrlAuth[0],
        password: proxyUrlAuth[1]
      };
    }
  }
}

但对于 no_proxy 什么也没有.似乎有一个对此的功能请求...与此同时，我将有到:

But nothing for no_proxy. Seems there is a feature request for this... In the meantime, i will just have to:

    delete process.env['http_proxy'];
    delete process.env['HTTP_PROXY'];
    delete process.env['https_proxy'];
    delete process.env['HTTPS_PROXY'];
