如何使用node-http-proxy进行HTTP到HTTPS路由

Question

这是我使用的模块版本:

$ npm list -g | grep proxy
├─┬ http-proxy@0.10.0

一个webservice调用到我的机器，我的任务是将请求代理到一个不同的url和主机，并根据请求正文的内容添加一个额外的查询参数:

var http      = require('http'),
    httpProxy = require('http-proxy')
    form2json = require('form2json');
httpProxy.createServer(function (req, res, proxy) {
  // my custom logic
  var fullBody = '';
  req.on('data', function(chunk) {
      // append the current chunk of data to the fullBody variable
      fullBody += chunk.toString();
  });
  req.on('end', function() {
      var jsonBody = form2json.decode(fullBody);
      var payload = JSON.parse(jsonBody.payload);
      req.url = '/my_couch_db/_design/ddoc_name/_update/my_handler?id="' + payload.id + '"';
      // standard proxy stuff
      proxy.proxyRequest(req, res, {
        changeOrigin: true,
        host: 'my.cloudant.com',
        port: 443,
        https: true
      });
  });
}).listen(8080);

但是我总是遇到这样的错误:An error has occurred: {"code":"ECONNRESET"}

有人知道这里需要修复什么吗?

Answer 1

这个对我很有用:

var httpProxy = require('http-proxy');
var options = {
  changeOrigin: true,
  target: {
      https: true
  }
}
httpProxy.createServer(443, 'www.google.com', options).listen(8001);

Answer 2

将所有来自3000端口的请求转发到https://google.com:

const https = require('https')
const httpProxy = require('http-proxy')
httpProxy.createProxyServer({
  target: 'https://google.com',
  agent: https.globalAgent,
  headers: {
    host: 'google.com'
  }
}).listen(3000)

受https://github.com/nodejitsu/node-http-proxy/blob/master/examples/http/proxy-http-to-https.js启发的例子。

Answer 3

经过一些尝试和错误，这对我有效:

var fs = require('fs')
var httpProxy = require('http-proxy');
var https = require('https');
var KEY  = 'newfile.key.pem';
var CERT = 'newfile.crt.pem';
httpProxy.createServer({
  changeOrigin: true,
  target: 'https://example.com',
  agent: new https.Agent({
    port: 443,
    key: fs.readFileSync(KEY),
    cert: fs.readFileSync(CERT)
  })
}).listen(8080);

Answer 4

对于http-proxy@1.18.1，我关闭secure，并且它有效。

const apiProxy = httpProxy.createProxyServer({ hostRewrite: true });
apiProxy.web(req, res, {
   target: "https://example.com",
   secure: false,
   changeOrigin: true,
});
