据我所知,我正在使用两种不同的方法做同样的事情:

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); });

当我运行此代码时,我得到 2 个不同的结果:
PS C:\Users\me> .\node\node.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......有人可以给我一个关于这两种行为如何/为什么不同的提示吗?

最佳答案

啊!

在 axios 源代码中挖掘后,我发现了这一点:

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]
      };
    }
  }
}

no_proxy 没有。似乎有一个 feature request for this ......与此同时,我只需要:
    delete process.env['http_proxy'];
    delete process.env['HTTP_PROXY'];
    delete process.env['https_proxy'];
    delete process.env['HTTPS_PROXY'];

关于javascript - 套接字在使用 axios.get 时挂断,但在使用 https.get 时不挂断,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/43433380/
