I'm trying to test my iPad app which accesses a web service currently running on my machine. How can I make it so the app can make calls to the web service?
The easiest way would be to connect your iPad and your PC to the same wireless network.
Every computer in your network has an unique Network IP (Usually something like "192.168.0.100"). If you know how to to connect to localhost it usually suffices to change the localhost to the network IP of the computer you're trying to access,
If your machine is a mac, I had a similar question which was answered here. Enable web sharing on the mac and everything should be available to you.

When developing and testing WP7 apps you're pc is connected to either a real WP7 phone or to the WP7 Device Emulator. For a specific development-purpose I would like to connect directly to the development pc (let's call it the host pc) from the WP7 app without having to rely on an external toast-server. I'm using plain sockets, System.Net.Sockets.Socket.
There seem to be two options:
Obtain the host pc's LAN IP and connect to that
Connect to localhost
Option 1 usually works well, but not always: The host pc may not necessaily have an IP, in which case there's nothing to connect to. Also, in some scenarios all LAN traffic is directed through a company-wide proxy which will disrupt this mechanism.
That lead me to try out option 2. To my surprise it seems to work, but I need to be more sure than simply "it seems to work". I've googled all over but can't find any definitive answer, not even on Microsoft's site like e.g. http://msdn.microsoft.com/en-us/library/ff754351(v=VS.92).aspx. So this is my question:
What exactly is the defined behavior of connecting to localhost from a WP7 app?
Altrernatively, is there a fool-proof way of connecting back to the host-pc?
(Let me stress this again: For this particular purpose I can't use toasts, because the development pc may not even be online.)
Edit:
I work at EQATEC and the application in question is the EQATEC Profiler. Right now the profiler/app-communication is handled by injecting a socket/http-client into the deployed WP7 app that connects back to the profiler's LAN IP address. It works very well and is really fast, but in some very rare cases users are offline and therefore doesn't have an IP, or have some prohibitive lan proxy rules.
Therefore connecting to "localhost" would be excellent if that somehow magically would always work for everybody. It works for me and a couple of test-users, but does it work for all our many thousand profiler users all over the world? I'd like to be more sure.
"localhost" by definition is the machine running the code (well specifically the NIC doing the communication). For either the Phone or the Emulator, that would mean the phone or the emulator, not the PC they are attached to.
When you attach to a PC, you do have a network - it's an RNDIS connection in which both sides get an IP address which traditionally (pre-WP7) could be resolved with 'ppp-peer', though I've not tested that resolution on the Phone. I suspect it will be the same, since WMDC is still what's connecting and they'd have little reason to change that connection mechanism.
If the emulator is resolving localhost to the PC on which is resides, that's a definite bug and I would not count on it continuing to work as they add more robust socket support to the Phone platform.
System.Net.Sockets.Socket isn't really currently available for WP7 programming, but it might be available at some future point (maybe in Mango... maybe...)
AFAIK, the only way to reliably do what you want to do is to set up an http server on the development PC and to provide your app with an HTTP address of that server - or to route messages via some "Cloud proxy"
I'm surprised localhost works at all on the real device... I can only assume that they are asking the connected PC to resolve that DNS name - but even then I'm surprised 127.0.0.1 works.
The ip you're looking for is "192.168.55.100"
That's the ip address the phone uses to connect to the host pc.
If you'd like to connect to the phone, apparently its ip address will be "192.168.55.101"
For the emulator just use localhost or 127.0.0.1
This is from the old ActiveSync days, so I don't know how official it is or how likely it is to last, but for right now at least it worked on my phone.
I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator.
But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server.
Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?
You need to bind the server to your external ip address. See the docs:
--address=...
The host address to use for the server. You may need to set this to be able to access the development server from another computer on your network. An address of 0.0.0.0 allows both localhost access and hostname access. Default is localhost.
I'm trying to test my iPhone application on the device.
I have a mac computer which stores my development environment.
Right now I can only access PHP files using the http://localhost/PHPFileLocation
which does not work when I try to test my app on real device.
How do I configure apache2 to be accessible from outside?
Is it possible to configure it to a specific IP address?
I want to reach some php scripts located on my development machine running apache2 from my iPhone device.
Thanks
If your computer has a WiFi card then you should be able to attach the iPhone remotely to a ad-hoc Wifi network created on your dev machine.
I'm assuming your Mac is behind a router. You should be able to configure your router to port forward connections to your WAN facing IP address to port 80 (the HTTP port) on your Mac - see http://portforward.com/ for some help.
You may also need to turn the firewall off on your Mac.
Once this is set up correctly you can hit http://yourexternalIP/PHPFileLocation in your iPhone app and this will be directed by your router to the Apache2 server on your Mac. The external IP is normally found on your router's admin page somewhere.
I asked a very similar question not too long ago and got some great responses. I've made it pretty far but still can't quite get things to talk. What I have is a PC running IIS and a web service inside of that. I'm trying to get the iPhone simulator on my Mac to be able to see this web service. I can ping my PCs local IP address from the Mac just fine, it's clearly alive and on the network. However, no matter what URL I enter into Safari the web service will not appear.
Any suggestions?
Thank you very much in advance.
Is this a web service or web application?
One fair possibility is that your Windows firewall could be blocking access to port 80. If it is, open your Windows firewall settings and add an exception for port 80 (Control Panel -> Windows Firewall -> Exceptions).
You might try using telnet on your Mac to test connecting to the web service/application.
I want to create an iPhone app which makes calls to a web service. For testing, I want to first create the API calls on my mac (server running XAMPP) and if it works fine there I want to port it to the actual server.
If my iPhone and mac are on the same network, can I access the web service using the IP address of my mac?
Thanks.
Any time someone answers with "why not," ignore the post. This just takes up space and adds absolutely no value...their post imitating their life.
Anyway, I access my laptop localhost (WAMP stack) from my iPod Touch by entering the IP address of my laptop on my Touch location bar. There is some configuration that needs to happen for this to work. I found what I needed at:
http://www.frihost.com/forums/vt-88381.html
Good Luck!
I can not speak about actual development, however I access intranet pages from a Ipod Touch all the time by either typing http ://ip or http://local_dns_name
As long as the iphone / ipod is on the network correctly (e.g. through standard wifi and not 3g/whatever) you should be able to access any and all local resources.
What I do:
Connected to the same network, I go in to the wireless settings and create a manual proxy that points to my machine. I use Charles proxy for testing a lot/seeing traffic, works like a charm and it lets me use my macbook hosts file so I don't need to do any funky listening rules in apache - just the same vhost settings I use on my machine already.

Why not?
Have you tried it and have some problems?
