I've noticed that GitHub launched a new "Clone in Mac" button a couple of months ago, which - when clicked - perform an external protocol request:
github-mac://openRepo/REPOURL
Assuming I want to implement a similar feature for my application, I wonder:
how do buttons degrade if the user browser doesn't support external protocols
how to register the protocol handler without requiring user action. In other words, how do you tell browser X to use application GitHub.app in case of protocol github-mac, without asking the user to tweak the browser settings?
I can see in the above URL an openRepo action, which inform the application about the action to perform. What are the common strategies/patterns to dispatch these requests for a Mac application, so that github-mac://first does something different from github-mac://second?
Browsers differ in the way they handle new protocols.
Check documentation here where they have documented various Operating Systems.
http://kb.mozillazine.org/Register_protocol
Its actually trivial to register a new protocol in Windows and hook it to a executable. I have done this for some apps:

We are controlling the sonos via a small IOT device. This device will be placed at the homes of our customers.
In our home automation system we need to know the playbackstate + volume of the players/groups.
At which polling rate can we ask these parameters ?
We cannot use a cloud server to handle the subscription events.
I tried to put a https webservice in the IOT device with a self signed certificate but this doesn't work.
After I have posted the subscription I get a request in my webservice but the cloud sonos server disconnects immediately.
Probably because of the certificate is self signed - Or can there be another reason ?
Is there another way to recieve status events ?
During discovery In the players Json object there is a key 'websocketUrl'.
The documentation says "The secure WebSocket URL for the device. See Connect for details".
But I cannot find more info about this.
Can this be used ?
At which polling rate can we ask these parameters?
Consider using subscriptions instead of polling. See this answer for more: https://stackoverflow.com/a/60893119/4902948

Is there another way to [receive] status events?
You must host a service that satisfies a set of requirements to receive events. See this answer for more: https://stackoverflow.com/a/57189717/4902948
Also see Details on API credentials and events in New features in versions 11.1, 11.2 (S1), & 12.0 (S2).
Can [the 'websocketUrl'] be used?
This is not publicly available for use.
It would be a lot easier to use the (undocumented but more useful) UPnP APIs. You could simply Subscribe to the UPnP RenderingControl endpoint, then you will get an event every time the volume changes. To find when the track changes, subscribe to AVTransport endpoint.
You can do this with a local server (this is how every Sonos app works after all) and no special cert requirements either.
UPnP events are described in the UPnP spec.
Your question doesn't provide details about the language you're using, but if the device is powerfull enough to run node, you have a good change with my sonos library.
You can just pull the required information from the device as often as you like. Or use the build-in event subscriptions. If you use the events, it will automatically setup an http listener and automatically subscribe to all the events you're listening for.
Events are instant (as in 50ms-100ms after the event took place on the device).
If you request information it is send directly to the device and the device will respond with the answer. Pulling multiple data points per second has never been a problem to me.
Warning as stated above, this uses the undocumented local UPNP api, but since their own app also uses it, I'm guessing that won't change soon.
I'm new to ServiceStack and want some validation on a pattern we're thinking about using.
We want to use ServiceStack with Xamarin and Message Queues. While I understand how REST works under the covers, I'm not sure how the Message Queues on ServiceStack work and if its appropriate for mobile devices.
Specifically we know that all mobile devices are essentially behind a NAT firewall setup by the Telco. Meaning Clients can talk to servers, but servers cant talk directly to clients, without the client talking first.
While the concept of a ServiceBus is designed specifically to handle this case, i'm not sure if its "mobile network friendly".
I would assume that the client side implementation, would need to work in one of two ways: polling, blocking get.
Polling would have the client side frequently runing a Http GET to ask the server if anything is available on a queue. A Blocking Get would, perform a Http GET but have the server return nothing until data is ready. Or is there another technique that i'm missing?
If it is a poll, is there any way to control the Poll frequencies in service stack. If its a blocking get how is this configured..
What happens when the app goes to the background, do we need to cancel the connections manually. etc.etc.
We tool an old version of the ServiceStack client library and ported them to xamarin. We now see that the latest ServiceStack client side library is Xamarin compatible.
So, basically my question is: Had anyone used Message Queues from a Xamarin Mobile to ServiceStack with RedisMQ or other server side message queue.
i'm too beginner in squid. i want a way to remain anonymous over the net. i also want to be able to access the contents of the internet which are filtered. my Windows computer is beyond firewall (filtered). my server (CentOS 5) is not. for example, when i enter http://facebook.com in the browser url, it redirects to an intranet ip which tells me to avoid going to this site!
now i've installed squid on server and traffic is propagated through this server. but this redirection occurs. so still i can't open filtered sites.
what can i do? a friend of mine told that the only way is to use https. ie. the connection between browser (Firefox) and the server must use this protocol. is it right? and how can i do that?
what's your suggestion? i don't want necessarily to use squid. besides, https protocol gets banned or decreased in speed in my country sometimes. so i prefer the protocol remain http. i thought also about writing a code in client and server to transform, compress/decompress and packetize as hoax binary http packets to be sent as much speed and success as possible. but i'm not an expert in this context and now i prefer more straightforward ways.
i respect any help/info.
I assume you are located in Iran. I would suggest using TOR if you mainly access websites. The latest release works reasonably well in Iran. It also includes an option to obfuscate traffic so it is not easily detectable that you are using TOR.
See also this question: https://tor.stackexchange.com/questions/1639/using-tor-in-iran-for-the-first-time-user-guide
A easy way to get the TOR package is using the autoresponder: https://www.torproject.org/projects/gettor.html
In case the website is blocked, it works as follows:
Users can communicate with GetTor robot by sending messages via email.
Currently, the best known GetTor email address is gettor#torproject.org.
This should be the most current stable GetTor robot as
it is operated by Tor Project.
To ask for Tor Browser a user should send an email to GetTor robot
with one of the following options in the message body:
windows: If the user needs Tor Browser for Windows.
linux: If the user needs Tor Browser for Linux.
osx: If the user needs Tor Browser for Mac OSX.
I'm trying to develop an extension that detects every connection made by the browser to figure out the URLs being accessed. I know that this is possible via writing an HTTP/SOCKS proxy and configuring the browser to flow traffic via that. However, that's kind of overkill for the application that I'm trying to develop and it's best done as a Firefox Add-on if that's possible. Any clues/pointers would be highly appreciated.
Use nsIHttpActivityDistributor and there is many information about the http transaction and socket transport through observeActivity callback.
Read the official documentation https://developer.mozilla.org/en/Monitoring_HTTP_activity.
I'm trying to port a win32 application to Windows Mobile 6 / 6.1 / 6.5. It uses winhttp which doesn't appear to be available on the mobile platforms.
My initial thought was to replace it with WinInet - but I wondered if anyone had a better idea?
WinInet is actually a more appropriate HTTP client library for client nodes.
Here's some things I like about WinInet voer WinHttp:
If your client app needs to make lots of requests from the same server, WinInet will implicitly queue the requests up so as not to flood the server. (But is transparent to the client app). In other words, it respects RFC 2616 guidelines on simultaneous connections. This is great when your app is pulling down a lot of images (or files) from the same server simultanously.
Will the use the IE cache for fetching content. (Which I assume an equivalent cache exists on Mobile platforms).
Proxy server auto-detected from IE settings. Probably less of an issue with mobile since the IP network is a bit more open. But if you had to support proxy servers with WinHttp, you'd have to use other API calls to specify the server directly.
I've used Wininet and it works. But it's not ideal as its timeouts are broken. And developing a complete asynchronous design with it required a ton of code.
So instead, I'm trying libcurl.
So far though, I still haven't managed to get it compile properly and link. Porting stuff is such a pain sometimes. But I digress. ;)
