Flex 4 - Technique to allow HTTPService testing locally and on development server - testing

Right now I have my URLs hard-coded for HTTPService to work with my local machine's web server so that I don't need to copy files to htdocs after compiling. What's a good technique to easily transition HTTPService URLs from working on my testing setup to working with a normal web server setup?

Write a service to get the current environment your application is in, similar to how one tests if you're running in AIR or Flex.
In your HTTPService:
url="EnvironmentService.getURL1();"
In EnvironmentService:
public static function getUrl1():URL
{
return (LOCAL_ENVIRONMENT)? LOCAL_URL1 : LIVE_URL1;
}
If this doesn't work for you, post some more code and we'll work on a solution

How can I replace the server in Web Component Tester

I have a project set up based around the Polymer Starter Kit, which includes Web-Component-Tester
This project includes php server code which I would also like to test by writing tests to run in the browser which will utilise the PHP server code through Ajax Calls.
This implies replacing the server that Web Component Tester is using ONLY when testing server side code. I hope to make a separate gulp task for this.
Unfortunately, I don't understand the relationship between WCT, Selenium and what ever server is run currently. I can see that WCT command starts Selenium, but I can't find out what the web server is and how that is started. I suspect it is WCT, because there is configuration of the mapping of directories to urls, but other than that I haven't a clue, despite trying to read the code.
Can someone explain how I go about making it run its own server when testing the client, but relying on an already set up web server (nginx) when running the server. I can set nginx to run from local host, or an other domain if that is a way to choose a different configuration.
EDIT: I have now found that runner/webserver.js starts an express server, and that urls get mapped so the base directory for the test runner and the bower_components directory both get mapped to the /components url.
What is currently confusing me is in what circumstances this gets run. It appears that loading plugins somehow does it, but my understanding from reading the code for this is tenuous.
The answer is that web component tester itself has a comment in the runner/config.js file.
In wct-conf.js, you can use registerHooks key into the Object that gets returned to add a function that does
registerHooks: function(wct) {
wct.hook('prepare:webserver', function(app, done) {
var proxy = require('express-http-proxy');
app.use('/api',
proxy('pas.dev', {
forwardPath: function(req, res) {
return require('url').parse(req.url).path;
}
})
);
done();
});
This register hook function allows you to provide a route (/api in my case) which this proxies to a server which can run the php scripts.

Grails generating proper links when deployed behind proxy

Consider the following setup for a deployed Grails application.
the Grails application is deployed on a Tomcat server (tomcat7)
in front of Tomcat an Apache webserver is deployed
Apache does SSL offloading, and acts as a proxy for Tomcat
So far a quite standard setup, which I have used succesfully many times. My issue is now with the links generated by the Grails application, especially those for the redirects (the standard controller redirects, which occur all the time e.g. after succesfully posting a form).
One configuration is different from all the other applications so far: in this Grails application no serverURL is configured. The application is a multi-tenant application, where each tenant is given it's own subdomain. (So if the application in general is running under https://www.example.com, a tenant can use https://tenant.example.com.) Subdomains are set automagically, that is without any configuration at DNS or Apache level. Grails can do so perfectly, by leaving out the serverURL property in Config.groovy: it then resolves all url's by inspecting the client host.
However: when generating redirect-url's, Grails is not aware the website is running under https. All redirect url's start with http... I guess this is no surprise, because nowhere in the application it is configured we are using https: there is no serverURL config, and technically the application is running on the standard http port of Tomcat, because of the SSL offloading and proxying by Apache.
So, bottom line: what can I do to make Grails generate proper redirects?
I have tried to extend the DefaultLinkGenerator and override the makeServerURL() method. Like this:
class MyLinkGenerator extends DefaultLinkGenerator {
MyLinkGenerator(String serverBaseURL, String contextPath) {
super(serverBaseURL, contextPath)
}
MyLinkGenerator(String serverBaseURL) {
super(serverBaseURL)
}
def grailsApplication
/**
* #return serverURL adapted to deployed scheme
*/
String makeServerURL() {
// get configured protocol
def scheme = grailsApplication.config.grails.twt.baseProtocol ?: 'https://'
println "Application running under protocol $scheme"
// get url from super
String surl = super.makeServerURL()
println "> super.makeServerURL(): $surl"
if (surl) {
// if super url not matching scheme, change scheme
if (scheme=='https://' && surl?.startsWith('http://')) {
surl = scheme + surl?.substring(7)
println "> re-written: $surl"
}
}
return surl
}
}
(Maybe not the most beautiful code, but I hope it explains what I'd like to do. And I left out the bit about configuring this class in resources.groovy.)
When running this code strange things happen:
In the log you see the code being executed, and a changed url (http > https) being produced, but...
The redirect sent to the browser is the unchanged url (http)
And even worse: all the resources in the generated views are crippled: they now all start with // (so what should be a relative "/css/myapp.css" is now "//css/myapp.css")
Any help or insight would be appreciated!
Grails version is 2.1.1 by the way (running a bit behind on upgrades...).
It seems you're always talking https to the outside world, so your cleanest option is to solve the problem where it originates, at your Apache webserver. Add to httpd.conf Header edit Location ^http://(.*)$ https://$1, and you're done.
If you have limitations that force you to solve this in your application you could do the rewrite of the Location header field in a Grails after interceptor. Details of that solution are in this post.
Some years have past since this question was written, but problems remain the same or at least similar ;-)
Just in case anyone hits the same/similar issue (that Grails redirect-URLs are http instead of https) ... We had this issue with a Grails 3.3.9 application running on OpenShift. The application was running in HTTP mode (on Port 8080) and the OpenShift Loadbalancer was doing the SSL-Termination.
We solved it by putting
server:
use-forward-headers: true
into our application.yml. After that Grails works perfect and all the redirects created were correct with https://.
Hint: We have do not use grails.serverURL in our configuration

Setting up XSockets on Windows Server 2003 R2, IIS6

I am looking for some guidance on setting up an MVC/XSockets project on our servers running Windows Server 2003, R2 with IIS6.
Our team is developing a webapp that uses XSockets 3.x to dynamically display data in real time. We are using our time entry system to show current time entries on a "dashboard." Employees enter their times via a separate app, and the dashboard app is supposed to show most recent activity updates.
The project is made using the MVC4 framework. This works great when testing from my development machine, separate from the server. The ws server instance is setup on ws://x.x.x.x:4502, where x.x.x.x is the server's IP. The XSockets components are integrated in the same project.
After pushing my local project onto the server and doing some setup, everything works okay except the XSockets functionality. The XSockets server cannot be accessed from outside the server. When I test from within the server, meaning opening up a browser and going to the webapp, it works fine as it does on my dev machine.
I have tried following the custom configuration setup outlined on xsockets.net, but I am a little confused as to how to define the ws server instance. Do I use the server's IP? The localhost IP (127.0.0.1)? I tried both, but it won't work. I tried adding this custom config settings:
public class XSocketsConfig : ConfigurationSetting
{
public XSocketsConfig() : base(new Uri("ws://dashboard.ourdomain.com:4502/"), new Uri("ws://x.x.x.x:4502")) { }
}
From javascript I access the XSocket through the "ws://dashboard.ourdomain.com:4502/" connection, but it didn't work when I tested it after deploying to the server. I also tried:
public class XSocketsConfig : ConfigurationSetting
{
public XSocketsConfig() : base(new Uri("ws://x.x.x.x:4502")) { }
}
or
public class XSocketsConfig : ConfigurationSetting
{
public XSocketsConfig() : base(new Uri("ws://127.0.0.1:4502")) { }
}
I did enable the server firewall to let traffic through port 4502. Again, everything works great on my local machine, so this leaves me to believe it is either a setting on the server, or a config setting for XSockets.
What is the proper way of achieving a client-server connection on IIS 6? Pointers and suggestions are greatly appreciated as my several-day search has yielded no effective results yet.
Okay so I have finally figured it out. It was after all a firewall issue. I had to configure the firewall to allow traffic on the public ip and port and to forward that traffic to the private ip and port. My XSockets configuration ended up looking like this:
//http://xsockets.net/docs/configuration#public--private-endpoint
public class XSocketsConfig : ConfigurationSetting
{
public XSocketsConfig() : base(new Uri("ws://x.x.x.x:4502/"), new Uri("ws://y.y.y.y:4502")) { }
}
Where x.x.x.x is the server's public IP address and y.y.y.y the private IP address on the LAN. On the client side (js) I then do:
var conn = new XSockets.WebSocket('ws://x.x.x.x:4502/Activity');
That took a serious amount of troubleshooting but I am glad I got it figured out.

Web Deploy API (deploy .zip package) Clarification

I'm using the web deploy API to deploy a web package (.zip file, created by MSDeploy.exe) to programmatically roll the package out to a server (we need to do some other things before we release the package which is why we're not doing it all in one go using MSDeploy.exe).
Here's the code I have. My question is really to clarify what is happening when this is executed. In the package parameters XML file I have the application name specified ("Default Web Site") but that's about it, there's no other params are specified in there. From testing the server it appears the package gets deployed successfully but my question is are any other settings on the server I'm deploying to getting changed without my knowledge, are any default settings published etc.? Things like security settings, directory browsing etc. that I might not be aware of? The code here seems to deploy the package but I'm anxious about using this on a production environment when I'm so unsure of how this API works. The MS documentation is not helpful (more like non-existant, actually).
DeploymentChangeSummary changes;
string packageToDeploy = "C:/MyPackageLocation.zip";
string packageParametersFile = "C:/MyPackageLocation.SetParameters.xml";
DeploymentBaseOptions destinationOptions = new DeploymentBaseOptions()
{
UserName = "MyUsername",
Password = "MyPassword",
ComputerName = "localhost"
};
using (DeploymentObject deploymentObject = DeploymentManager.CreateObject(DeploymentWellKnownProvider.Package,
packageToDeploy))
{
deploymentObject.SyncParameters.Load(packageParametersFile);
DeploymentSyncOptions syncOptions = new DeploymentSyncOptions();
syncOptions.WhatIf = false;
//Deploy the package to the server.
changes = deploymentObject.SyncTo(destinationOptions, syncOptions);
}
If anyone could clarify that this snippet should deploy a package to a web site application on a server, without changing any existing server settings (unless specified in the SetParameters.xml file) that would be really helpful. Any good resources on using the API or an explanation of how web deployment works behind the scenes would also be much appreciated!
The setparameters file just controls the value for the parameters defined in the package. A package might be doing much more than that. Web deploy has a concept of providers and any given package can have one or more providers.
If you want to make sure that the package is not changing server side settings the best approach you can take is to use the API but make the packages be deployed via Web Management Service. This will give you two benefits:
You can control what providers you allow through.
You can add users and give restricted permissions to them to deploy to their site or their folder etc.
The alternate approach is to:
In the package manually look at the archive.xml and look for the providers in the package. As long as you dont see any of the following providers that can cause server settings change such as apphostconfig or webserver or regkey (this is not a comprehensive list) you should be good. Runcommand is a provider that allows you to execute batch scripts or commands. While it is a good provider for admins themselves you need to consider whether you want to allow packages with such providers to run.
You can do the above mentioned inspection in code by calling getchildren on the deployment object you create out of the package and inspect the providers and the provider paths.

Kohana Auth Library Deployment

My Kohana app runs perfectly on my local machine.
When I deployed my app to a server (and adjust the config files appropriately), I can no longer log into the app.
I've traced through the app login routine on both my local version and the server version and they both agree with each other all the way through until you get to the auth.php controller logged_in() routine where suddenly, at line 140 - the is_object($this->user) test - the $user object no longer exists!?!?!?
The login() function call that calls the logged_in() function successfully passes the following test, which causes a redirect to the logged_in() function.
if(Auth::instance()->login($user, $post['password']))
Yes, the password and hash, etc all work perfectly.
Here is the offending code:
public function logged_in()
{
if ( ! is_object($this->user))
{
// No user is currently logged in
url::redirect('auth/login');
}
etc...
}
As the code is the same between my local installation and the server, I reckon it must be some server setting that is messing with me.
FYI: All the rest of the code works because I have a temporary backdoor available that allows me to use the application (view pages of tables, etc) without being logged in.
Any ideas?
I solved the problem (DUH!).
The answer was that the cookie.php config file had $config['domain'] = 'localhost'. Setting this to the actual domain that the app is installed in magically made my life happy again!
Thanks everyone for your help and interest.
