How do I access the time provided by internet time services like time.nist.gov from within my Flex mobile application?
Is there a way to do this via URLRequest or HTTPService?
Alright, here is the call to the Yahoo WebServices with a simple HTTPService;
<s:HTTPService id="serverTime" url="http://developer.yahooapis.com/TimeService/V1/getTime?appid=myID" result="resultHandler(event)" resultFormat="e4x"/>
In my resultHandler, the trace on Timestamp already fails (returns no value);
private function resultHandler(event:ResultEvent):void {
// this works (outputs the xml as shown on Yahoo
trace(event.result);
var xmlResult:XML = event.result as XML;
var timestamp:String = xmlResult.Timestamp;
trace("stamp" + timestamp);
}
time.nist.gov (or any other time server) use NTP protocol for communication, not HTTP, so you can't use URLRequest or HTTPService.
I don't know of any NTP client implementation in ActionScript. You may need to do your own.
Depending on your needs, you may use a webservice that provides "pretty accurate" time, like Yahoo WebServices. This goes over HTTP, so you can use URLRequest or HTTPService in Flex.

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).
I come here because I am searching (like the title mentionned) to do a query from geotools (through geoserver) to get feature from a solr index.
To be more precise :
I saw on geoserver user manual that i can do query on solr like this in http :
http://localhost:8080/geoserver/wfs?service=WFS&version=1.1.0&request=GetFeature
&typeName=mySolrLayer
&format="xxx"
&viewparams=q:"mySolrQuery"
The important part on this URL is the viewparams that I want to use directly from geotools.
I have already test this case (this is a part of my code):
url = new URL(
"http://localhost:8080/geoserver/wfs?request=GetCapabilities&VERSION=1.1.0";
);
Map<String, String> param = new HashMap();
params.put(WFSDataStoreFactory.URL.key, url);
param.put("viewparams","q:myquery");
Hints hints = new Hints();
hints.put(Hints.VIRTUAL_TABLE_PARAMETERS, viewParams);
query.setHints(hints);
...
featureSource.getFeatures(query);
But here, it seems to doesn't work, the url send to geoserver is a normal "GET FEATURE" request without the viewparams parameter.
I tried this with geotools-12.2 ; geotools-13.2 and geotools-15-SNAPSHOT but I didn't succeed to pass the query, geoserver send me all the feature in my database and doesn't take "viewparams" as a param.
I need to do it like this because actually the query come from another program and I would easily communicate this query to another part of the project...
If someone can help me ?
There doesn't currently seem to be a way to do this in the GeoTool's WFSDatastore implementations as the GetFeature request is constructed from the URL provided by the getCapabilities document. This is as the standard requires but it may be worth making a feature enhancement request to allow clients to override this string (as QGIS does for example) which would let you specify the additional parameter in your base URL which would then be passed to the server as you need.
Unfortunately the WFS module lives in Unsupported land at present so unless you have resources to work on this issue yourself and can provide a PR to implement it there is not a great chance of it being implemented.
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.
In my GAE app (Python) I have implemented multitenancy and multi-site support based on the host part of the request object.
For example, www.foo.com/index.html and www.bar.com/index.html are both handled by the same app (e.g. myapp.appspot.com). The app reads the host-value and then decides which namespace and site-configuration to use. This works great as long as the app receives the request directly from the user-agent.
However, I would like to use the Channel API, but there is an issue because requests to /_ah/channel/connected/ and /_ah/channel/disconnected/ are not originating from the original user-agent. Instead, the request has Host: myapp.appspot.com and the parameter to=myapp.appspot.com. (The from parameter is the token I expect. Also www.foo.com/_ah/channel/jsapi is redirected to a talkgadget server which is not documented but seems to be as expected.)
I assume, the problem is caused by the code in channel.js which doesn't call my app using the original host, e.g. www.foo.com/_ah/channel/connected. Instead it uses a talkgadget.google.com host which (as far as I can tell) will then call my app, but using myapp.appspot.com, ignoring the original host and so I cannot use the request's host value for my purpose.
As a workaround, I can figure out a way of including the host information into the channel token, so when my connected and disconnected handlers receive the token, they can use the token instead.
However, I would like to know if there is a better approach, where I could still get the original host name (e.g. www.foo.com) requests to /_ah/channel/connected/ and /_ah/channel/disconnected/. Any ideas?
This is what I have tried so far (with-out any success):
Adding the custom domain host name to the JS src attribute:
<script type="text/javascript" src="//www.foo.com/_ah/channel/jsapi"></script>
I also tried to manually override the base-url of the channel socket, suggested here: https://stackoverflow.com/questions/16558776/google-app-engine-channel-api-same-origin-policy
<script type="text/javascript">
onOpened = function() {
// TODO
};
onMessage = function() {
// TODO
};
onError = function() {
// TODO
};
onClose = function() {
// TODO
};
goog.appengine.Socket.BASE_URL = "https://www.foo.com/_ah/channel/";
channel = new goog.appengine.Channel('{{channelToken}}');
socket = channel.open();
socket.onopen = onOpened;
socket.onmessage = onMessage;
socket.onerror = onError;
socket.onclose = onClose;
</script>
I couldn't find any official documentation for channel.js and I don't want to implement something that is going to break easily with the next update by Google.
Short of a proxy, I don't see a better way than including the information in-band. The problem is that the library/infrastructure (can't be certain without looking deeper) is stripping the HTTP-layer information (the Host header), and indeed you don't have any control of the HTTP layer to pass custom headers, etc. So, you either need to have the info at a lower layer (TCP doesn't even provide a means to do this, and since the entrypoint of your code is through the browser running channel.js, rather than a system-level process running on the bare network interface, this is out of the picture decisively), or at a higher layer, ie. within the channel.
Most of the solutions I've come across for Sharepoint doc library uploads use the HTTP "PUT" method, but I'm having trouble finding a way to do this in Silverlight because it has restrictions on the HTTP Methods. I visited this http://msdn.microsoft.com/en-us/library/dd920295(VS.95).aspx to see how to allow PUT in my code, but I can't find how that helps you use an HTTP "PUT".
I am using client web-services, so that limits some of the Sharepoint functions available.
That leaves me with these questions:
Can I do an http PUT in Silverlight?
If I can't or there is another better way to upload a file, what is it?
Thanks
Figured it out!! works like a charm
public void UploadFile(String fileName, byte[] file)
{
// format the destination URL
string[] destinationUrls = {"http://qa.sp.dca/sites/silverlight/Answers/"+fileName};
// fill out the metadata
// remark: don't set the Name field, because this is the name of the document
SharepointCopy.FieldInformation titleInformation = new SharepointCopy.FieldInformation
{DisplayName =fileName,
InternalName =fileName,
Type = SharepointCopy.FieldType.Text,
Value =fileName};
// to specify the content type
SharepointCopy.FieldInformation ctInformation = new SharepointCopy.FieldInformation
{DisplayName ="XML Answer Doc",
InternalName ="ContentType",
Type = SharepointCopy.
FieldType.Text,
Value ="xml"};
SharepointCopy.FieldInformation[] metadata = { titleInformation };
// initialize the web service
SharepointCopy.CopySoapClient copyws = new SharepointCopy.CopySoapClient();
// execute the CopyIntoItems method
copyws.CopyIntoItemsCompleted += copyws_CopyIntoItemsCompleted;
copyws.CopyIntoItemsAsync("http://null", destinationUrls, metadata, file);
}
Many Thanks to Karine Bosch for the solution here: http://social.msdn.microsoft.com/Forums/en/sharepointdevelopment/thread/f135aaa2-3345-483f-ade4-e4fd597d50d4
What type of SharePoint deployment and what version of silverlight? If say it is an intranet deployment you could use UNC paths to access your document library in sharepoint and the savefiledialog/openfiledialog available in Silverlight 3.

Silverlight has restrictions on what it can do with local files, though I've read that silverlight 4 has some changes.
