Better error handling:
Suppose you are developing a web application that makes API requests from the client browser. Most likely, your browser will not allow you to because you will be breaking the pesky 'Same-origin policy'. To over come this, your express.js web server must send out http request and deliever the response back to the web client. Thus, this is known as proxying the http request(your api call out) from your
browser client -> to the express.js web server -> to the new host. This module will allow you to do this. In addition, you can use as many proxies/routes as you would like.
Http verbs Supported: patch, post, put, del, and head.
Requirements(dependencies installed automatically):
process.env['NODE_TLS_REJECT_UNAUTHORIZED'] = '0';into your express.js's
app.jsor similar express config file to turn off ssl cert checking.
Assumeing you already have a express.js or some kind of generator project already established:
npm install express-multi-proxy-router
app.js), place the middle ware as such in the last 2 lines where you a list of app.use().
4.At the top of that same express.js configuration file(typically called
app.js), place these 2 lines:
var bodyParser = require("body-parser");var proxyUrl = require("express-multi-proxy-router");
Usage and Configuration:
Let's say in your client browser code you call out to /api/v1/goto-identity-api and /api/v2/get-list-of-servers. Both of these api's go to compeletley seperate hosts. You will modify your
proxies_config.ini file located at
node_modules/express-multi-proxy-router/proxies_config.ini with the following config:
[proxies]#Add your hosts here in the format of#host = urlhttps://identity.api.foobar.com/v2.0/tokens = /api/v1/goto-identity-apihttp://hosting.company.servers/api/servers = /api/v2/get-list-of-servers
notice that that
http is specified. Be sure you specify this when setting yours.
After this is set, when the client browser sends out a http request to
/api/v1/goto-identity-api, express.js will see that the url is
/api/v1/goto-identity-api. It will then send out it's own request to
https://identity.api.foobar.com/v2.0/tokens and return the response back to the client browser.
There is no limit to how many proxies you can add, add as many as you like.
