I'm new to angularjs. I'm working on a angularjs project which was started by other ppl. In the code, some functions are defined as the format $http('url', parameters). The urls are something like 'abc/def/hijk'. I want to modify the functions but I cannot find the location of the urls. where can I find the source files given the links? thanks.
Is this more of an environment/domain question?
$http is just an angular core service for make http requests.
When you say
I want to modify the functions but I cannot find the location of the urls. where can I find the source files given the links?
That is a very open ended question. If for example my angular site is hosted at http://mysite.local and the links looks like $http.get('/someUrl', config), then I would visit http://mysite.local/someUrl to see what is there. If it is in fact connecting to the same domain then ping it.
ping mysite.local
Whatever IP address you get back you may be able to resolve the hostname
ping -a 192.168.0.80
If this was a windows machine you could rdc and check the iis instance, otherwise ssh and check whats hosting on port 80?
Essentially what I'm getting at is... we don't no where your predecessor may have stored source or what your environment is setup like but with some investigation you may be able to shed some light.

I run Google Ads on my Google-App-Engine-hosted website (www.bigriddles.com), and they tell me I need to have an "ads.txt" file served from the root domain (i.e. http://bigriddles.com/ads.txt, as opposed to http://www.bigriddles.com/ads.txt).
My DNS is hosted on Gandi, and I created their "ALIAS" record (which I think just does CNAME flattening or something similar) to alias "bigriddles.com" to "ghs.googlehosted.com." I chose "ghs.googlehosted.com" because that's what I CNAMEd "www.bigriddles.com" to (many years back), and that CNAME has been working fine.
However, now when I visit "bigriddles.com", I get an "HTTP 301 Moved" to "www.bigriddles.com", and as far as I can tell, this response isn't coming from any code I wrote (I've looked through my code and don't see anything that would redirect this). Furthermore, there is a "Server: ghs" header in the response from "bigriddles.com", whereas if I visit "www.bigriddles.com", which works fine, the response includes the header "Server: Google Frontend". I'm not sure if there is some hint of my problem in the difference between those two Server headers.
Anyway, I'm not sure exactly what's going wrong. It could be a DNS issue. I say this because "dig www.bigriddles.com" comes back with the IP 172.217.14.115, whereas "dig bigriddles.com" comes back with "172.217.168.211", so maybe one of these really is a "ghs" server and the other is a "Google Frontend" server (I'm not sure the difference) and this "ALIAS" DNS solution just isn't going to work.
More likely though I feel like maybe there is just some settings problem with my App itself where it's not set up to allow the apex domain "bigriddles.com", and if I change that setting it will start working?
I have gone through the steps on https://cloud.google.com/appengine/docs/standard/python/mapping-custom-domains. When I view the "Custom Domains" for my project, I see "www.bigriddles.com" and "m.bigriddles.com", but I don't see the naked domain "bigriddles.com". However, when I try to add it on that page, it tells me that "bigriddles.com" is already mapped to a project, so I'm not sure what to make of that.
Any help would be appreciated, thank you!
This seems like an issue with your domain provider.
You can use this tool that might help you contact the domain provider with detailed info.
If they insist it's not an issue on their side (I strongly believe it is), then you should contact Google Cloud Platform Support so a deeper inspection can be made on your project.
If you're also using G Suites for your domain, the criminal is G Suites' Domain -> Redirect. If it is, it's a pity that Google does not let us turn off the so-called feature.
Since G Suites use as the same entry point as App Engine, you have no chance to solve this other than moving your site outside Google services or stop using G Suite.
I am calling a third party web service from app engine. This particular service is picky. I ran into an issue where calls would work fine for a while, then stop working, then start working again. I realized that if I manually stopped all instances in the admin console, that the calls would work again.
I setup a proxy to route the calls through that so I could see the headers and all detail. I think I have tracked the issue down to the following. After an instance has been up for a while (the app usually just needs 1 to 3 instances right now) app engine will start using the IP address of the destination as the value for the host header instead of the hostname. Well the service doesn't like that. Whether it should care is another matter.
So my question is, why does app engine use the ip address for the host header eventually instead of the hostname? And, of course, is there anything I can do about it? I know that I cannot set the host header, but maybe there is something else that can be done.
Thanks for any insight.
First, thank you for finding this behavior. We have had intermittent issues with urlfetch for a long time, and will try to detect if this is the issue.
One thing you could try is to target a specific instance/module:
http://instance.version.module.app-id.appspot.com
and cycle through the instances. If you just target the module, it will kill the instance after some inactivity. So, perhaps that would not trigger the GAE DNS shortcut.
Another trick would be to add a fake, random, query string after your url: ?foo=D7hfka67h. Perhaps that would prevent GAE from recognizing the repeat url, and trying to shortcut the DNS.
Using the windows host file located in
windows/system32/drivers/etc/host
Is it possible to respond a request from an application like when it is offline(not connected to the Internet)? Could you please give an example of this is done.
The hosts file only lists aliases for ip-addresses. For example:
192.168.0.1 foo bar foo.com bar.com
If that line is in the hosts file, then you can use the host-names foo, bar, foo.com and bar.com to reach the computer with ip-address 192.168.0.1.
If the computer, or the service you want to reach on that address, is not online, you can't reach it no matter what you have in your hosts file.
If you are willing to map your local development environment to a domain name, you can edit the domain name in hosts file and map it to 127.0.0.1, which is the loopback address.
That way, any requests done to that particular domain will fallback to your local machine.
You can also assign different LAN/WAN IP addresses.
When your development phase is done, you can remove the entry.
I would not recommend doing so, stick with the localhost and just make use of that to test virtualhosts setup or some sort of domain based configurations.
If there is anything else I can answer, please don't hesitate to post further comments on my answer.
If you mean to respond to HTTP requests then you need a Web Server configured to respond to any host (or that specific host name) on port 80. If you are not using it for anything else IIS can do this1 – configure it to return 404 (not found) or some other relatively neutral fail response.
1 If IIS is already being used then things get much harder, later versions of IIS are more flexible either with a combination of using HTTP.SYS to allow other applications to respond to certain URLs or using different Web Sites in IIS (until Windows 7, or maybe Vista, only available on Server editions of Windows).
I'm doing https web requests in silverlight using "WebRequest"/"WebResponse" framework classes.
Problem is: I do a request to an url like: https://12.34.56.78
I receive back a versign signed certificate which has as subject a domain name like: www.mydomain.com.
Hence this results in a remote certificate mismatch error.
First question: Can I somehow accept the invalid certificate, and get the WebBresponse content ? (even if it involves using other libraries, I'm open to it)
Additional details: (for those interested on why I need this scenario)
I'm trying to give a client access to a silverlight app deployed on a test server.
Client accesses the silverlight app at: www.mydomain.com/app
Then I do some rest requests to: https://xx.mydomain.com
Problem is I don't want to do requests on https://xx.mydomain.com, since that is on our productive server. For this reason I use https://12.34.56.78 instead of https://xx.mydomain.com.
Client has some firewalls/proxies and if I simply change his hosts file and map https://xx.mydomain.com to 12.34.56.78, web requests don't resolve to the mapped IP.
I say this because on his network webrequests fail if I try that, on my network I can use the hosts changing without problems.
UPDATE: Fixed the problem by deploying test releases to an alternative: https://yy.domain.com and allowing the user to configure for test purposes, the base url to which I do requests to be: https://yy.domain.com.
Using an certificate that contained the IP in the subject or an alternative subject would've probably worked too, but would have cost some money to be issued by a certified provider and would not be so good because IP's might change.
After doing more research looks like Microsoft won't add this feature too soon, unless there's a scenario for non-testing/debugging uses.

I'm working on building a Silverlight application whereas we want to be able to have a client hit a url like:
http://{client}.domain.com/
and login, where the {client} part is their business name. so for example, google's would be:
http://google.domain.com/
What I was wondering was if anyone has been able, in silverlight, to be able to use this subdomain model to make decisions on the call to the web server so that you can switch to a specific database to run a query? Unfortunately, it's something that is quite necessary for the project, as we are trying to make it easy for their employees to get their company specific information for our software.
Wouldn't it work to put the service on a specific subdomain itself, such as wcf.example.com, and then setup a cross domain policy file on the service to allow it to access it?
As long as this would work you could just load the silverlight in the proper subdomain and then pass that subdomain to your service and let it do its thing.
Some examples of this below:
Silverlight Cross Domain Services
Silverlight Cross Domain Policy Helpers
On the server side you can check the HTTP 1.1 Host header to see how the user came to your server and do the necessary customization based on that.
I think you cannot do this with Silverlight alone, I know you cannot do this without problems with Javascript, Ajax etc. . That is because a sub domain is - for security reasons - treated otherwise than a sub-page by the browsers.
What about the following idea: Insert a rewrite rule to your web server software. So if http://google.domain.com is called, the web server itself rewrites the URL to something like http://www.domain.com/google/ (or better: http://www.domain.com/customers/google/). Would that help?
Georgi:
That would help if it would be static, but alas, it's going to all be dynamic. My hope was to have 1x deployment for the application, and to use the http://google.domain.com/ idea to switch to the correct database for the user. I recall doing this once when we built an asp.net website, using the domain context to figure out what skin to use, etc.
Ates: Can you explain more about what you are saying... sounds like you are close to what I am trying to come up with. Have you seen such a tutorial for this?
The only other way I have come up with to make this work is to have a metabase that when the user logs in, it will switch them to the appropriate database as required... was just thinking as well that telling Client x to hit:
http://ClientX.domain.com/ would have been sweeter than saying to hit http://www.domain.com/ and login. It seemed as if they were to hit their name, and to show it personalized for them right from the login screen would have been much more appealing for the client base.
#Richard B: No, I can't think of any such tutorial that I've seen before. I'll try to be more verbose.
The server-side approach in more detail:
Direct *.example.com to the same IP in your DNS settings.
The backend app that handles login checks the Host HTTP header (e.g. the "HTTP_HOST" server variable in some platforms). That would contain the exact subdomain.example.com that the client used for reaching your server. Extract the subdomain part and continue...
There can also be a client-side-only approach. I don't know much about Silverlight but I'm assuming that you should be able to interface Silverlight with JavaScript. You could read document.location with JavaScript and pass it to your Silverlight applet, whereon further data fetching etc. logic would rely on the subdomain that was passed in by JavaScript.
#Ates:
That is what we did when we wrote the ASP.Net system... we pushed a slew of *.example.com hosts against the web server, and handled using the HTTP headers. The hold-up comes when dealing with WCF pushing the info between the client and the server... it can only exist in one domain...
So, for example, when you have {client}.example.com and {sandbox}.example.com, the WCF service can't be registered to both. It also cannot be registered to just *.example.com or example.com, so that's where the catch 22 is coming in at. everything else I have the prior knowledge of handling.
I recall a method by which an application can "spoof" another domain name in certain instances. I take it in this case, I would need to do such a configuration? Much to research yet I believe.
