I am designing a website using ember and express over node. Its running in a server, say: SERVER_1.
I have few webservices running in another server, say: SERVER_2.
That is:
website in SERVER_1 and webservices available in SERVER_2
SERVER_1 is behind a proxy server. And I am trying to access webservices from SERVER_1:
SERVER_1 =====[PROXY]===> SERVER_2
When I make AJAX webservice calls from SERVER_1, I receive:
NetworkError: 500 Internal Server Error
However, I am able to retrieve values successfully through browser. Only through AJAX code, I am retrieving Network 500 error.
Also for testing, I removed my proxy server setup:
SERVER_1 =====> SERVER_2
and I was able to access all those web services successfully both via AJAX code and browser.
If I have a proxy server in between them:
SERVER_1 =====[PROXY]===> SERVER_2
I am getting -- NetworkError: 500 Internal Server Error
I like to know the procedures to access third-party webservices from a website which is running behind a proxy server?
Additional Info:
Already to fix cross domain web-service access issue (website running in one server and webservices running in some other different servers with different ports), I am using http-proxy npm and my code is as follows:
var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');
var httpProxy = require('http-proxy');
var endpoint = {
host: 'IP_ADDRESS_WHERE_MY_WEBSERVICES_RUN',
port: 80,
prefix: '/api'
}
var proxy = new httpProxy.RoutingProxy();
var app = express();
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(express.cookieParser('xxxxx'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
app.use(function(req, res) {
if (req.url.indexOf(endpoint.prefix) === 0) {
proxy.proxyRequest(req, res, endpoint);
}
});
app.use(express.bodyParser());
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', routes.index);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
My AJAX call:
$.ajax({
type: 'GET',
async: false,
url: 'API_URL',
success: function (data) {
alert('success');
},
failure: function(error){
alert('error');
}
});
Already I using http-proxy to handle all url's request.
How can I configure my proxy server's IP address and port in the above code, so that I can access all these webservices successfully? Or is there some way to have my proxy configurations in AJAX call?
Can anyone please guide me?
Thank you
errorevents. Just listen to the error event andconsole.logit, so that we know what's happening. – Dactylography
