我想使用标准的 http.Client 从 node.js 进行传出 HTTP 调用.但是我无法直接从我的网络访问远程服务器，需要通过代理.

Tim Macfarlane's answer was close with regards to using a HTTP proxy.

使用 HTTP 代理(用于非安全请求)非常简单.您连接到代理并正常发出请求，只是路径部分包含完整的 url 并且主机标头设置为您要连接的主机.
蒂姆非常接近他的答案，但他错过了正确设置主机标头.

Using a HTTP proxy (for non secure requests) is very simple. You connect to the proxy and make the request normally except that the path part includes the full url and the host header is set to the host you want to connect to.
Tim was very close with his answer but he missed setting the host header properly.

var http = require("http");

var options = {
  host: "proxy",
  port: 8080,
  path: "http://www.google.com",
  headers: {
    Host: "www.google.com"
  }
};
http.get(options, function(res) {
  console.log(res);
  res.pipe(process.stdout);
});

为了记录，他的回答确实适用于 http://nodejs.org/ 但那是因为他们的服务器没有不在乎主机头不正确.

For the record his answer does work with http://nodejs.org/ but that's because their server doesn't care the host header is incorrect.
