As with unetstack shell we can delete a route but how to delete a route in the groovy code without using the Agent
Refer to the documentation for Routing service in the Unet handbook for how to do this. Essentially you need to send a EditRouteReq created using the deleteRoute() constructor method, and send it to the agent providing the ROUTING service.
For example, if you want to delete all routes to node 10, this will look something like:
def router = agentForService(Services.ROUTING)
def req = EditRouteReq.deleteRoute()
req.to = 10
def rsp = router << req
// rsp will have performative AGREE if the request was successful

Apache camel components page have fields under option and query parameters but no clear path position for parameters , from samples I was able to make out they go along options .
I would like to know the difference between options and query parameters.
When an application with Apache Camel starts, it registers the routes in the Camel Context, and once the context is started, components present in from () and to () cannot be modified, for example:
String param = "a = xxxx & y = bbb";
...
to ("http4: //api.xxx.yy?" + stop)
...
It will only be evaluated at startup, so even if the value of the string in the param variable changes, the route will always use a=xxxx&y=bbb as the default since it has already been initialized in the context of Camel (you can see Camel recording the routes in the logs during application startup).
The options can undergo changes not only in construction, depending on the design of the component in question, but can also be exposed for configuration via starters using application.yml or application.properties or via java as in the example below:
application.properties
camel.component.http.http-configuration=br.com.pack.impl.MyHttpConfiguration
In java
HttpConfiguration config = new HttpConfiguration();
config.setProxyAuthMethod("Digest");
config.setProxyAuthUsername("myUser");
config.setProxyAuthPassword("myPassword");
HttpComponent http = context.getComponent("http", HttpComponent.class);
http.setHttpConfiguration(config);
from("direct:start")
.to("http4://www.google.com/search");
I hope it helped to clarify a little more
Options are used to configure Component and Query Parameters are used while creating endpoints.
I am trying to implement signalR in angularJS,
I want to pass relative url to hub connection, but it's making current url (on which my angular application is hosted)
My API base url : http://localhost:81/NrsService/api/TestSignal
My angular application running at
http://localhost:81
Here is my signalR setup :
$.connection.hub.url = "/NrsService/api/TestSignal";
//Getting the connection object
connection = $.hubConnection();
Like it is sending request at http://localhost:81/signalr/negotiate? but I want it to be http://localhost:81/NrsService/api/TestSignal/negotiate?
You have to edit the generated JavaScript code where the client proxy is defined. As of SignalR 2.4.0 there is a createHubProxies function defined where you should find this line of code:
signalR.hub = $.hubConnection("/signalr", { useDefaultPath: false });
Change it to the following to prevent the "/signalr" ending in your requests:
signalR.hub = $.hubConnection("", { useDefaultPath: false });
After that, you can simply change the url which should be called the way you provided in your question, e.g.:
$.connection.hub.url = "/NrsService/api/TestSignal";
If you also want to change this Url dynamically, you can use the document.location properties. In my case, I did something like this:
var subPath = document.location.pathname.substr(0, document.location.pathname.lastIndexOf("/"));
$.connection.hub.url = subPath; // subpath equals to "/NrsService/api"
Hope this helps.
I'm currently using Solr 4.3.1. i have configured dih for my solr. i would like to do a full import through command prompt. I know the url will be something like this http://localhost:8983/solr/corename/dataimport?command=full-import&clean=true&commit=true is there any method i can do this without using curl ?
Thanks
Edit
string Text = "http://localhost:8983/solr/Latest_TextBox/dataimport?command=full-import&clean=true&commit=true";
var wc = new WebClient();
var Import = wc.DownloadString(Text);
Currently using the above code
Call it like a normal REST url that's it !! I am using it in my application for importing and indexing data from my Local drive and it just works fine ! :) . Use HttpURLConnection to make a request and capture response to see whether it was successful or not . You don't need any specific API to do that . This is a sample code to make a GET request correctly in C# .Try data import handler url with this, it may work !
Console.WriteLine("Making API Call...");
using (var client = new HttpClient(new HttpClientHandler { AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate }))
{
client.BaseAddress = new Uri("https://api.stackexchange.com/2.2/");
HttpResponseMessage response = client.GetAsync("answers?order=desc&sort=activity&site=stackoverflow").Result;
response.EnsureSuccessStatusCode();
string result = response.Content.ReadAsStringAsync().Result;
Console.WriteLine("Result: " + result);
}
Console.ReadLine();
}
}
}
You'll have to call the URL in some way - Solr only operates through a REST API. There is no command line API (the command line tools available just talk to the API). So use your preferred way to talk to a HTTP endpoint, that being curl, wget, GET or what's available for your programming language of choice.
The bundled solrCli application does not have any existing command for triggering a full-import as far as I were able to see (which would just talk to the REST API by calling the URL you've already referenced).
Following is my App Engine Endpoint. I annotate it as ApiMethod.HttpMethod.GET because I want to be able to make a get call through the browser. The class itself has a few dozen methods understandably. Some of them using POST. But getItems is annotated with GET. When I try to call the url through a browser, I get a 405 error
Error: HTTP method GET is not supported by this URL
The code:
#Api(name = "myserver",
namespace = #ApiNamespace(ownerDomain = "thecompany.com", ownerName = "thecompany", packagePath = ""),
version = "1", description = "thecompany myserver", defaultVersion = AnnotationBoolean.TRUE
)
public class myserver {
#ApiMethod(name = "getItems", httpMethod = ApiMethod.HttpMethod.GET)
public CollectionResponse<Item> getItems(#Named("paramId") Long paramId) {
…
return CollectionResponse.<Item>builder().setItems(ItemList).build();
}
}
This is not for localhost, it’s for the real server. Perhaps I am forming the url incorrectly. I have tried a few urls such as
https://thecompanymyserver.appspot.com/_ah/spi/com.thecompany.myserver.endpoint.myserver.getItems/v1/paramId=542246400
https://thecompanymyserver.appspot.com/_ah/spi/myserver/NewsForVideo/v1/542246400
The proper path for this is /_ah/api/myserver/1/getItems. /_ah/spi refers to the backend path, which only takes POST requests of a different format.
Side note: API versions are typical "vX" instead of just "X".
You can use the api explorer to find out whether you're using the correct url. Go to
https://yourprojectid.appspot.com/_ah/api/explorer
this works on the devserver as well:
http://localhost:8080/_ah/api/explorer
Also if you're not planning to use the google javascript api client you should add path="..." to your #ApiMethods, so you are sure about what the path actually is.
I am having problems getting the logout link work in GAE (Python).
This is the page I am looking at.
In my template, I create a link
<p>Logout</p>
But when I click on it I get "broken link" message from Chrome. The url for the link looks like this:
http://localhost:8085/users.create_logout_url(
My questions:
Can anybody explain how this works in general?
What is the correct url for the dev server?
What is the correct url for the app server?
What is the ("/") in the logout url?
Thanks.
EDIT
This link works; but I don't know why:
<p>Logout</p>
What sort of templates are you using? It's clear from the output that you're not escaping your code correctly.
Seems to me that you want to do this instead:
self.response.out.write("This is the url: %s", users.create_logout_url("/"))
You could also pass it to your template, using GAEs implemented django templates.
from google.appengine.ext.webapp import template
...
...
(inside your request handler)
class Empty: pass
data = Empty()
data.logout = users.create_logout_url("/")
self.response.out.write(template.render(my_tmpl, {'data': data})
A useful approach is to add all sorts of info to a BaseRequestHandler and then use this as base class for all of your other request handler classes.
from google.appengine.ext import webapp
...
class BaseRequestHandler(webapp.RequestHandler):
def __init__(self):
webapp.RequestHandler.__init__(self) # extend the base class
class Empty: pass
data = Empty()
data.foo = "bar"
Then your new classes will have access to all the data you provided in the base class.
class OtherHandler(BaseRequestHandler):
def get(self):
self.response.out.write("This is foo: %s" % self.data.foo) # passes str "bar"
Hope it helps.

Hi following more or less what this article is showing for the user account stuff. In gwt I store server side the logout/login url and I pass them to the client
