I have a local web service using Jersey and the path looks something like
http://localhost:5000/search?...
Then I installed the Hystrix dashboard to my Tomcat following this tutorial https://github.com/Netflix/Hystrix/wiki/Dashboard
What URL do I use in the highlighted text box? I have tried localhost:5000/hystrix.stream, but it didn't work (my local service was running).
It turned out that I didn't register the servlet.
I use dropwizard so just added the following code and it worked.
environment.getApplicationContext().addServlet("com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet", "/hystrix.stream");

I am trying to build an action messaging extension with a task module implementation which uses a URL attribute to load the page. Attached is the screenshot of the task module code which was generated by Yeoman Teams generator.
The popup comes up blank. So it means it's not loading the HTML file path, but if I open Chrome and try to load the URL, it works fine.
Also instead of using URL if I use an adaptive card it works fine. Only the URL part doesn't load on the popup. Attached is another screenshot of the popup inside teams:
What could be wrong with the code?
The other answer is correct in that your url needs to be reflected 100% correctly in your manifest. However, there are a few things that you need to be clear on:
It's not per se the address of the BOT that's important, but rather the address of the web page itself that needs to be listed in your safe domains list in your manifest. In your case, they're hosted in the same endpoint, but they might not be in your final solution, depending on how you end up hosting this.
While you're developing locally, rather use App Studio. That way, you don't need to fiddle with the zip file every time - you can just change it in App Studio and immediately redeploy with the updated URL
Every time when you compile and run the project, a new hostname is generated since ngrok free license is used in the yo teams scaffolding, which makes the app to reference to the old URL.
You need to uninstall the app from the Teams app store under your organization and upload the new app from the package folder .zip (Only after gulp ngrok-serve)
If it still does not work, check the below
Unzip the package file and verify the manifest whether it's pointing to the right hostname of the action html page
Go to http://localhost:4040 to inspect the ngrok tunnel traffic that should give more info on the routed requests.
Ok, i found this link https://code.google.com/p/gwt-platform/wiki/CrawlerSupport#Using_gwtp-crawler-service that explain how you can make your GWTP app crawlable.
I got some GWTP experience, but i know nothing about AppEngine.
Google said its "crawlservice.appspot.com" can parse any Ajax page. Now I have a page "http://mydomain.com#!article" that has an artice that was pulled from Database. Say that page has the text "this is my article". Now I open this link:
crawlservice.appspot.com/?key=123456&url=http://mydomain.com#!article, then i can see all javascript but I couldn't find the text "this is my article".
Why?
Now let check with a real life example
open this link https://groups.google.com/forum/#!topic/google-web-toolkit/Syi04ArKl4k & you will see the text "If i open that url in IE"
Now you open http://crawlservice.appspot.com/?key=123456&url=https://groups.google.com/forum/#!topic/google-web-toolkit/Syi04ArKl4k you can see all javascript but there is no text "If i open that url in IE",
Why is it?
SO if i use http://crawlservice.appspot.com/?key=123456&url=mydomain#!article then Can google crawler be able to see the text in mydomain#!article?
also why the key=123456, it means everyone can use this service? do we have our own key? does google limit the number of calls to their service?
Could you explain all these things?
Extra Info:
Christopher suggested me to use this example
https://github.com/ArcBees/GWTP-Samples/tree/master/gwtp-samples/gwtp-sample-crawler-service
However, I ran into other problem. My app is a pure GWTP, it doesn't have appengine-web.xml in WEB-INF. I have no idea what is appengine or GAE mean or what is Maven.
DO i need to register AppEngine?
My Appp may have a lot of traffic. Also I am using Godaddy VPS. I don't want to register App Engine since I have to pay for Google for extra traffic.
Everything in my GWTP App is ok right now except Crawler Function.
So if I don't use Google App Engine, then how can i build Crawler Function for GWTP?
I tried to use HTMLUnit for my app, but HTMLUnit doesn't work for GWTP (See details in here Why HTMLUnit always shows the HostPage no matter what url I type in (Crawlable GWT APP)? )
I believe you are not allowed to crawl Google Groups. Probably they are actively trying to prevent this, so you do not see the expected content.
There's a couple points I wish to elaborate on:
The Google Code documentation is no longer maintained. You should look on Github instead: https://github.com/ArcBees/GWTP/wiki/Crawler-Support
You shouldn't use http://crawlservice.appspot.com. This isn't a Google service, it's out of date and we may decide to delete it down the road. This only serves as a public example. You should create your own application on App Engine (https://appengine.google.com/)
There is a sample here (https://github.com/ArcBees/GWTP-Samples/tree/master/gwtp-samples/gwtp-sample-crawler-service) using GWTP's Crawler Service. You can basically copy-paste it. Just make sure you update the <application> tag in appengine-web.xml to the name of your application and use your own service key in CrawlerModule.
Finally, if your client uses GWTP and you followed the documentation, it will work. If you want to try it manually, you must encode the Query Parameters.
For example http://crawlservice.appspot.com/?key=123456&url=http://www.arcbees.com#!service will not work because the hash (everything including and after #) is not sent to the server.
On the other hand http://crawlservice.appspot.com/?key=123456&url=http%3A%2F%2Fwww.arcbees.com%2F%23!service will work.
I'm trying to download data from my Google App Engine app, using the official instructions
Remote API is set up & I call:
appcfg.py download_data --application=appname --url=http://app.address.com/_ah/remote_api --filename=alldata.csv
The connection is established, I'm being asked for my e-mail & password, and then a long trace appears ending up with this:
google.appengine.api.datastore_errors.BadRequestError: app s~appname cannot access app appname's data
Any ideas?
If using the high-replication datastore, change the value passed to --application from appname to s~appname.
Found the problem - as an URL I was giving my own app's domain name instead of the 1.appname.appspot.com.
I ran into this same issue, but when attempting to use the remote API from a custom script as opposed to appcfg.py's bulk downloader.
This issue may have been addressed in more recent GAE SDK releases, but for various reasons I'm still using the older 1.7 release. I found the answer in this bug report: https://code.google.com/p/googleappengine/issues/detail?id=4374
Basically, when calling ConfigureRemoteApi, don't specify the APP_ID argument (just pass None) and specify your app ID via the host argument, e.g. 'myapp-hrd.appspot.com'. ConfigureRemoteApi will figure out your app ID correctly and won't add the 's~' that causes this problem.
I'm trying to make http requests from my Google App Engine webapp, and discovered I have to use URLConnection since it's the only whitelisted class. The corresponding Clojure library is clojure.contrib.http.agent, and my code is as follows:
(defroutes example
(GET "/" [] (http/string (http/http-agent "http://www.example.com")))
(route/not-found "Page not found"))
This works fine in my development environment- the browser displays the text for example.com. But when I test it out with Google's development app server:
phrygian:example wei$ dev_appserver.sh war
2010-09-28 14:53:36.120 java[43845:903] [Java CocoaComponent compatibility mode]: Enabled
...
INFO: The server is running at http://localhost:8080/
It just hangs when I load the page. No error, or anything. Any idea what might be going on?
http-agent creates threads so that might be why it does not work.
From the API documentation:
Creates (and immediately returns) an Agent representing an HTTP
request running in a new thread.
You could try http-connection, which is a wrapper around HttpURLConnection, so this should work.
Another alternative is to try clj-http. The API seems to be a bit more high-level, but it uses Apache HttpComponents which might be blacklisted.
I am guessing http.async.client is a definite no-go due to its strong asynchronous approach.
You might want to try appengine.urlfetch/fetch from appengine-clj (http://github.com/r0man/appengine-clj, also in clojars)
I have a silverlight business aplication that gets data from silverlight enabled webservice.
When I run the application in dev environment, it works fine.
when i deploy the application and the Asp.net web development server is working, then to the application works fine.
But when I stop the development server, the application can't access a service.
My questions are:
When I deploy a silverlight business application, doesn't the service get deployed and get started.
The endpoint address in my ServiceReferences.Clientconfig file is endpoint address="http://localhost:9702/MyWebservice.scv. Do I need to change this?
The enpoint address in the web.config is blank.
Appreciate your help
Because the WCF client code is declared as a "partial" class, what I've been doing to this point is creating another c# partial class file to host a GetClient() method on it. You'll notice that the code is taking into account the port that the service is on... in a few of the environments that I've posted or will be posting to, as well as the development environment, the application is not always on port 80.
Namespace Project.Service
{
public partial class ServiceClient
{
public static ServiceClient GetClient()
{
return new ServiceClient("CustomBinding_Service",
new System.ServiceModel.EndpointAddress(new Uri(string.Format("{0}://{1}:{2}/Services/Service.svc",
Application.Current.Host.Source.Scheme, Application.Current.Host.Source.Host, Application.Current.Host.Source.Port), UriKind.Absolute)));
}
}
}
Hope this helps someone!
Yes you are going to want to change your endpoint address. I recommend doing it in the silverlight code when creating the connection to the WCF service. The service itself lives on the web server, whereas the silverlight application lives on the clients computer. If the web server stops, the web service stops but the silverlight app can keep running.
edit:
To do this in code, as long as the path is always in the same domain as the app you can use do like so:
BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None) //Use whatever security you need here
{
MaxReceivedMessageSize = int.MaxValue,
MaxBufferSize = int.MaxValue
};
Client client = new Client(binding, new EndpointAddress(new Uri(Application.Current.Host.Source, "../MyService.svc")));
Thanks so much for your help. I tried your approach to create the client code but that didn't work. And that's because the problem seems to be somewhere else.
So I installed fiddler to see the traffic.
Fiddler showed that the service was being accessed but the http response code was 302 showing that there was some redirection involved.
The address of my application is like this http:///Silverlightapp/(S(oirppxrwzhlf2a2vbia1ui45))/Default.aspx#/Home and it is hosted on IIS 6.
So I had to employ a workaround by installing the service on machine with IIS7 (and there was no session id involved like in the above url).I still kept the silverlight application hosted on IIS 6.
Anyway, in summary, to anyone who reads the thread, I did the following to troubleshoot and solve issue(temporarily)
Changed the end point address in the ServiceReferences.ClientConfig file. When you add the service using discover option in VS, the endpoint address is of the localhost and this must be changed.
Registered the service model using ServiceModelReg -i command. (this solved my problem that my applicaiton was only working from development server and not IIS)
-Put the CrossDomain and ClientAccessPolicy files in c:]inetpub\wwwroot folders.
-Used fiddler to look at http response codes. I had to do no configuration in fiddler.
Changed the binarymessageEncoding to textMessageEncoding iin the web.config file of the silverlight web project that also hosted the ecf service. I did this becasue adding a silverlight enabled wcf service creates a custom binding configuration in the web.config file by default uses binary encoding. I needed text encoding to see errors in fidder. But this didn't help much becasue I only saw the name of the operation in the Inspector>xml tab in fiddler. This was the same even after my issues was resolved by workaround.
Thanks for the help
Don't do it in code. Otherwise you won't be able to change it later without recompiling the application (when the address will need to change, perhaps years down the road when you've lost the source code :)
Change the address in ServiceReferences.ClientConfig to where the service is actually hosted... e.g. http://example.com/myVdir/MyWebservice.svc
If later on you need to change the address without recompiling:
- Open the .xap file (it's just a zip file with a different extension)
- Find the .ClientConfig file and change the address
- Put it back together as a .zip file and rename to .xap
Also, I can't remember anymore whether the .ClientConfig supports relative addresses (e.g. just "MyWebService.svc"), but if it does it may be a good solution as well.
