Node http-proxy and express
提问by BRogers
I'm trying to do something like this:
我正在尝试做这样的事情：
// Setup prox to handle blog requests
httpProxy.createServer({
hostnameOnly: true,
router: {
'http://localhost': '8080',
'http://localhost/blog': '2368'
}
}).listen(8000);
Previously I was using this:
以前我是用这个：
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});
Basically, I want to still use express... but, when people go to http://localhost/blogget taken to the blog but still be served over port 8080(which will eventually be port 80)
基本上，我仍然想使用 express ......但是，当人们去访问http://localhost/blog博客但仍然被服务时port 8080（最终将是端口 80）
So I switched it to this and it worked better. The problem is that express takes over the routing (from what I can tell)
所以我把它换成了这个，效果更好。问题是快递接管了路由（据我所知）
var options = {
// pathnameOnly: true,
router: {
'localhost': 'localhost:8080',
'localhost/blog': 'localhost:2368'
}
}
// Setup prox to handle blog requests
var proxyServer = httpProxy.createServer(options);
proxyServer.listen(9000);
require('./app/server/router')(app);
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});

Using http-proxy 1.0 with express:
将 http-proxy 1.0 与 express 一起使用：
var httpProxy = require('http-proxy');
var apiProxy = httpProxy.createProxyServer();
app.get("/api/*", function(req, res){
apiProxy.web(req, res, { target: 'http://google.com:80' });
});

A very straightforward solution which works seamlessly, and with cookies/authentication as well, using express-http-proxy:
一个非常简单的解决方案，可以无缝工作，也可以使用 cookie/身份验证，使用express-http-proxy：
var proxy = require('express-http-proxy');
var blogProxy = proxy('localhost/blog:2368', {
forwardPath: function (req, res) {
return require('url').parse(req.url).path;
}
});
And then simply:
然后简单地：
app.use("/blog/*", blogProxy);
I know I'm late to join this party, but I hope this helps someone.

I got this working.
我得到了这个工作。
- Install Ghostand make sure it's working property (default port is 2368)
- Create your node web app using express (listen on port 80) - nothing special here
- Install node-http-proxy
npm install http-proxyin your web app Create wildcard route for /blog* that proxies requests to Ghost service
var httpProxy = require('http-proxy'); var proxy = new httpProxy.RoutingProxy(); app.get('/blog*', function (req, res, next) { proxy.proxyRequest(req, res ,{ host: 'moserlap.splitvr.com', port: 2368 }); });Update the Ghost config to use a sub directory (only supported in 0.4.0+)
config = { // ### Development **(default)** development: { // The url to use when providing links to the site, E.g. in RSS and email. url: 'http://127.0.0.1/blog', ...You should now be able to hit http://yoursite.com/blogand all routes work.
- 安装 Ghost并确保它的工作属性（默认端口为 2368）
- 使用 express（侦听端口 80）创建您的节点 Web 应用程序 - 这里没什么特别的
- 在您的 Web 应用程序中安装node-http-proxy
npm install http-proxy 为代理对 Ghost 服务的请求的 /blog* 创建通配符路由
var httpProxy = require('http-proxy'); var proxy = new httpProxy.RoutingProxy(); app.get('/blog*', function (req, res, next) { proxy.proxyRequest(req, res ,{ host: 'moserlap.splitvr.com', port: 2368 }); });更新 Ghost 配置以使用子目录（仅在 0.4.0+ 中支持）
config = { // ### Development **(default)** development: { // The url to use when providing links to the site, E.g. in RSS and email. url: 'http://127.0.0.1/blog', ...您现在应该可以访问http://yoursite.com/blog并且所有路由都可以正常工作。

I have used simple solution to proxified my GET/POST requests.
我使用了简单的解决方案来代理我的 GET/POST 请求。
var httpProxy = require('http-proxy');
var apiProxy = httpProxy.createProxyServer();
app.post("/api/*", function(req, res) {
apiProxy.web(req, res, { target: 'http://localhost:5000'})
});
app.get("/api/*", function(req, res) {
apiProxy.web(req, res, { target: 'http://localhost:5000'})
});
another easier way to handle all type of requests is:
处理所有类型请求的另一种更简单的方法是：
app.all("/api/*", function(req, res) {
apiProxy.web(req, res, { target: 'http://localhost:5000'})
});
NOTE: above functions must be before bodyparser.
注意：以上函数必须在bodyparser之前。
