Node.js 全局代理设置 [英] Node.js global proxy setting

问题描述

我在代理服务器后面的公司网络中工作.在我的代码中，我可以使用 这个线程.

I was working in a corporate network behind a proxy server. In my code I can set the proxy by using the approach mentioned in this thread.

但问题是大多数第3方模块没有代理设置，我无法修改他们的代码来添加代理.此外，我的代码可能用于直接连接环境，这意味着我无法在代码中硬编码我的代理设置.

But the problem is that most of the 3rd party modules do not have proxy setting and I cannot modify their code to add the proxy. Also, my code might be used in a direct connection environment which means I cannot hard-code my proxy setting in code.

我知道 NPM 有一个全局代理设置

I know NPM has a global setting for proxy which is

npm config set proxy http://proxy.company.com:8080
npm config set https-proxy http://proxy.company.com:8080

但我没有在 Node.js 中找到任何类似的配置.

But I didn't find any config similar in Node.js.

Node.js 是否支持全局代理设置，无需更改所有代码，轻松开关机?

Does Node.js support global proxy setting so that I don't need to change all codes and switch on and off easily?

推荐答案

不幸的是，似乎每次调用 http.request 时都必须设置代理信息.Node 不包含全局代理设置机制.

Unfortunately, it seems that proxy information must be set on each call to http.request. Node does not include a mechanism for global proxy settings.

global-tunnel-ng 模块然而，在 NPM 上似乎可以处理这个问题:

The global-tunnel-ng module on NPM appears to handle this, however:

var globalTunnel = require('global-tunnel-ng');

globalTunnel.initialize({
  host: '10.0.0.10',
  port: 8080,
  proxyAuth: 'userId:password', // optional authentication
  sockets: 50 // optional pool size for each http and https
});

在通过调用 initialize 建立全局设置后，http.request 和 request 库 将使用代理信息.

After the global settings are establish with a call to initialize, both http.request and the request library will use the proxy information.

模块也可以使用http_proxy环境变量:

The module can also use the http_proxy environment variable:

process.env.http_proxy = 'http://proxy.example.com:3129';
globalTunnel.initialize();
