multi-proxy-server v1.0.3

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.
