Nodejs Passport Oauth2代理

Question

我建立了自己的护照策略。现在我的应用程序的一个实例运行在公司防火墙后面。因此，我需要首先将所有传出请求传递给代理服务器（http），然后连接到外部世界（https）。我使用其他模块运行，例如request，它提供了传递代理配置的选项。

`app - （http） - ＆gt;代理 - （https via vpn tunnel） - ＆gt; www``

问题

1）如何强制我护照策略的传出请求通过代理？

2）如果不可能，只需添加护照选项：如何获得使用代理的所有传出请求？

我注意到策略中有一个代理选项： https://github.com/jaredhanson/passport-oauth2/blob/master/lib/strategy.js#l110

我试图扩展我的策略并传递此选项，但它没有成功。

e.g

Strategy = (options, verify) ->
  options = options or {}
  options.authorizationURL = options.authorizationURL or 'https://mywebsite.com/oauth2/authorize'
  options.tokenURL = options.tokenURL or 'https://mywebsite.com/extern/oauth2/auth_form.aspx' 
  options.scopeSeparator = options.scopeSeparator or ','
  options.proxy = options.proxy or process.env['HTTP_PROXY']

Answer 1

我可以最终解决所有传出请求的问题：

代码

inspect = require('eyespect').inspector({maxLength: null})
chalk = require('chalk')

url = require('url')
http = require('http')
https = require('https')

setupHttpProxy = ()->
  proxyHttp = url.parse(process.env['HTTP_PROXY'])
  # console.log chalk.bgRed "proxyHttp"
  # inspect proxyHttp
  http.globalAgent.options.host = proxyHttp.hostname
  http.globalAgent.options.port = proxyHttp.port
  # console.log chalk.bgRed "proxyAgent"
  # inspect http.globalAgent
  return

setupHttpsProxy = ()->
  proxyHttps = url.parse(process.env['HTTPS_PROXY'])
  # console.log chalk.bgRed "proxyHttps"
  # inspect proxyHttps
  https.globalAgent.options.host = proxyHttps.hostname
  https.globalAgent.options.port = proxyHttps.port
  # console.log chalk.bgRed "proxyAgent"
  # inspect https.globalAgent
  return

module.exports = ()->
  setupHttpProxy() if process.env['HTTP_PROXY']?
  setupHttpsProxy() if process.env['HTTPS_PROXY']?
  return

我扩展了全局代理，该代理用作所有传出连接的默认设置。
