Nodejs request 模块和 https 模块请求同一个文件 uri 时， request 模块请求失败

[s609926202]

神奇的是，使用 https 模块时可以正常访问 uri 并保存在本地，但是使用 request 模块时请求都发不出去，百思不得其解，报错信息如下：

Error: tunneling socket could not be established, cause=getaddrinfo ENOTFOUND 7890
    at ClientRequest.onError (D:\www\BWK_Spider\node_modules\tunnel-agent\index.js:177:17)
    at Object.onceWrapper (node:events:642:26)
    at ClientRequest.emit (node:events:527:28)
    at Socket.socketErrorListener (node:_http_client:454:9)
    at Socket.emit (node:events:527:28)

    at processTicksAndRejections (node:internal/process/task_queues:83:21) {
  code: 'ECONNRESET'
}

request 模块代码：

const request = require("request");
const fs = require("fs");

request("https://xxx.xx.xx/20_C12100030.pdf")
  .pipe(fs.createWriteStream("C:\\Users\\444\\Desktop\\20_C12100030.pdf"))
  .on("close", function (err) {
    console.log("下载完成");
    console.log(err);
  })
  .on("error", function (err) {
    console.log(err);
  });

https 模块代码

const https = require("https");

const file = fs.createWriteStream(
  "C:\\Users\\444\\Desktop\\20_C12100030.pdf"
);
https
  .get("https://xxx.xx.xx/20_C12100030.pdf", (response) => {
    console.log("请求成功");
    response.pipe(file);

    // after download completed close filestream
    file.on("finish", () => {
      file.close();
      console.log("Download Completed");
    });
  })
  .on("error", (err) => {
    console.log("Error: ", err.message);
  });

有遇到这种情况的吗？网上搜索都说是 npm 代理导致的，但实际不是，否则使用 https 模块时也应该是请求发不出去才对。

7890 这个显然是你的梯子代理端口

[Pastsong]

request 读了你的 HTTP_PROXY/HTTPS_PROXY 环境变量

@okakuyang
我梯子可正常访问呐

https 模块又不会自动走代理
