MultiProxyServer

In some case,a local server would be setup for developing,but sometime remote server APIs can't be called successfully due to

1. CROS header is not set

2. http/https mismatch

3. remote server may ask for cookies to be set.(which is CROS too)

what we do

A multi proxy server that can make several servers in each different domain act as a single server.

It forwards request for processing API calls to servers that don't send CORS headers or support HTTPS.

install

npm install multi-proxy-server

Notice

1. Dont support https yet
2. We suggest this is only be used in develop mode.Don't use as a production.

how to set

Edit config.js

exapmle:

// Listen port
exports.port = process.env.PORT || 3000;
// Log request message into console
exports.enable_logging = true;
// The lenght of time we'll wait for a proxy server to respond before timing out.
exports.proxy_request_timeout_ms = 10000; 
// Forwarding settings
//Check if the url to be forward is match the pattern "check",if so forward it to "url".
exports.forwards = [
    {
        check  : /^\/tif/,
        url    : "https://somedomain.com/tif"
    },
    {
        check  : /^\/dev/,
        url    : "http://127.0.0.1:8888/dev"
    },{
        check  : /^\/app/,
        url    : "http://127.0.0.1:8080/dest/app"
    }
];
// If none of the "forwards" is matched,this become the forwarding address.
// http , https
exports.else_forward_url = "http://127.0.0.1:8080/dest";

This config setting will listen to port 3000.

When request url http://127.0.0.1:3000/tif/api/getFoo was send.multi-proxy-server will forward it to https://somedomain.com/tif/api/getFoo,which is defined in config.js, and add CROS headers.

notice

The way we determin forwarding url.

1. The url_path of http://127.0.0.1:3000/tif/api/getFoo is "/tif/api/getFoo"
2. remove macthed pattern ^/tif in url_path
3. the rest part is "/api/getFoo"
4. append rest path to "forwards.url"
5. it become https://somedomain.com/tif/api/getFoo

thanks for

This proxy server is based on thingproxy,and many modification was made to fit and get new features.
