Socket IO . How to change url path - url

How to change url path of socket.io.js
my socket.io.js is located at
https://192.168.236.100/socket.io/socket.io.js
what if i want to change it like:
https://192.168.236.100/socket.conference/socket.io.js
thank you

It is not as simple as changing the this._path value or passing in the path option to the constructor because if you change that, it also affects how a socket.io client must connect to the server too, not only how the socket.io.js file is served.
The simplest way I could find to make the socket.io.js file appear to be coming from a different path and not change anything else is to just create a new route for it like this:
app.get("/socket.conference/socket.io.js", function(req, res) {
res.sendFile(path.join(__dirname, "node_modules/socket.io-client/socket.io.js"));
});
This assumes that socket.io is installed locally in the directory that your app file is running from. If it is installed somewhere differently, then you need to find where the /socket.io-client/socket.io.js path/file is and use the right path to that.
This works with this client <script> tag:
<script src="/socket.conference/socket.io.js"></script>

OpenLayers: Loading a TileJSON from a local file

I'm trying to implement a local copy of a TileJSON in an iOS app through Cordova. The issue I'm having is that OpenLayers doesn't seem to recognise the JSON file as valid and thus doesn't show any tiles. I have tried local and remote versions of the same TileJSON and looked at the Console Logs, the local one has a status of "error" (but no explanation as to what that error might be...).
I think the issue is down to the fact that the JSON file is being loaded using a file: URL, rather than http:. I have put the JSON file on a remote server and this not only loads fine but actually loads the tiles from the local path.
Can OpenLayers be tricked into accepting the local file as a valid JSON file? Can Cordova be forced to load local files via HTTP? I think either of these options would fix the issue.
Thanks
EDIT: Here's the code I'm using to load the TileJSON:
var mapLayer = new ol.layer.Tile({
source: new ol.source.TileJSON({
url: getPhoneGapPath() + 'tiles.json',
crossOrigin: 'anonymous'
})
});
this.map.addLayer(mapLayer);
function getPhoneGapPath() {
var path = window.location.pathname;
path = path.substr( path, path.length - 10 );
return path;
}
The getPhoneGapPath() function is used to get the path to the webroot of the Cordova app.
This is probably related to a bug in OpenLayers, https://github.com/openlayers/ol3/issues/5647. The fix will be in the next release.
Also make sure that you configure Cordova to allow access to file:// urls when the application is served from a file:// url. The equivalent option in Chrome is --allow-file-access-from-files.

Filename not assigned to csv export in HighCharts on Mac

I am using the EXPORT-CSV plugin for Highcharts to export data to csv. (Thank you to the developers of this plugin!) When testing in Safari on a Mac, however, the exported csv file does not take the filename as expected from
exporting: {
filename: "FancyFileName"
}
and instead just uses the default Highcharts name "chart". All the built-in export types do use the desired filename from Safari, and the csv also gets the desired filename from all the other standard browsers I have tested.
Here is a fiddle.
How can Safari be convinced to use the filename I give it? Thanks for your help.
The hard coded filename is coming from the php script written on the server. You can find that script on php script for download of file with hardcoded file name
You can use that same code on your local machine server. To do that
create a php file on your local server.
copy the above code in it.
change url www.highcharts.com/studies/csv-export/csv.php in export.csv library to your local server url.
change the name whatever you wish to using $_POST['variablename']
Variable name should be pass when making post call from export.csv library and use in php file using $_POST
Highcharts.post(url, {
data: content,
name: name,
type: MIME,
extension: extension
});
This is the code used in export.csv library for making post call. I have added extra parameter name to be used in my php script for dynamic filename.

Use local json file with Cordova/ionic/Angular. Works in browser, but not on device?

I'm attempting to use a JSON object living in a data.json file to be the dataset for a quick prototype I'm working on. This lives in a my_project/www/data/ directory. I have an Angular service that goes and grabs the data within this file using $http, does some stuff to it, and then it's used throughout my app.
I'm using Cordova and Ionic. When using ionic serve on my computer, everything looks perfect in the browser. However, when using ionic view (http://view.ionic.io/) and opening the app on my iPad, I see a:
{"data":null,"status":0,"config":{"method":"GET","transformRequest":[null],"transformResponse":[null],"url":"../data/items.json","headers":{"Accept":"application/json,test/plain,*/*}},"statusText":""}
for a response. I would think that if it were a relative URL issue, that it would also not work in the browser, but that is not the case.
Here's what I'm doing:
config.xml has this line:
<access origin="*" subdomains="true"/>
My service that preforms the simple request is doing:
return $http.get("../data/data.json").then(function (response) {
return response.data;
});
And finally, in my controller, I ask for the service to preform the request:
myService.goGetData().then(onComplete, onError);
In my browser, onComplete() is invoked and on the iPad, onError() is invoked.
Any guidance?
On your local developer machine you're actually running a webserver when you run ionic serve. So a path like ../../data.json will work because it is totally valid in the context of the webserver that has complete filesystem access.
If, however, you try to do the same thing on your device, you're probably going to run into an issue because the device has security policies in place that don't allow ajax to traverse up outside of the root. It is not a dynamic webserver so it can't load files up the tree. Instead you'd use something like the cordova file plugin to grab the file contents from the filesystem. If you prefer, you can use ngCordova to make interacting with the plugin a bit less painful.
I am 99% sure this is what is happening but you can test my theory by pointing your $http call to some dummy .json data hosted on a publicly available server to see if it works. Here is some dummy json data.
Just gonna leave this here because I had the same problem as the original question author. Simply removing any starting slashes from the json file path in the $http.get function solved this problem for me, now loading the json data works both in the browser emulator and on my android device. The root of the $http call url seems to always be the index.html folder no matter where your controller or service is located. So use a path relative from that folder and it should work. like $http.get("data/data.json")
So this is an example json file. save it as data.json
[
{
"Name" : "Sabba",
"City" : "London",
"Country" : "UK"
},
{
"Name" : "Tom",
"City" : "NY",
"Country" : "USA"
}
]
And this this is what a example controller looks like
var app = angular.module('myApp', ['ionic']);
app.controller('ExhibitionTabCtrl', ['$scope', '$http', function($scope,$http) {
$http.get("your/path/from/index/data.json")
.success(function (response)
{
$scope.names = response;
});
}]);
Then in your template make sure you are you are referencing your controller.
<ion-content class="padding" ng-controller="ExhibitionTabCtrl">
You should then be able to use the a expression to get the data
{{ names }}
Hope this helps :)
I was also looking for this and found this question, since there is no real answer to the problem I kept my search on the Internet and found this answer at the Ionic Forum from ozexpert:
var url = "";
if(ionic.Platform.isAndroid()){
url = "/android_asset/www/";
}
I've used it to load a 3D model and its textures.
update: ionic 2 beta (version date 10 Aug 2016)
You must add prefix to local url like this: prefix + 'your/local/resource'.
prefix by platform:
ios = '../www/'
android = '../www/'
browser = ''
we can create an urlResolver provider to do this job.
notice: only change url in *.ts code to access local resource, don's do this with remote url or in html code.
Have fun and good luck with beta version.
An Starter Ioner
It is possible to access local resources using $http.get.
If the json file is located in www/js/data.json. You can access using
js/data.json
Do not use ../js/data.json. Using that only works in the local browser. Use js/data.json will work on both local browser and iOS device for Cordova.

how to get a static file (.json) palced in myapp/apps/myapp/jsons/ through SC.Request.getUrl

My sprout core app name is myapp. My directory structure is myapp/apps/myapp/.
I have created a directory named jsons inside myapp/apps/myapp/, and placed a file called emp.json, I want to get this file through ajax using SC.Request.getUrl. I tried the following but didn't work. I want to know the url to reach out this file.
SC.Request.getUrl('/myapp/apps/myapp/resources/emp.json').notify(this, this.didFetchContacts)
.send();
SC.Request.getUrl('/myapp/resources/emp.json').notify(this, this.didFetchContacts)
.send();
Thanks
Ok, you will need to use static_url. So if emp.json is in your resources directory, you can call this:
SC.Request.getUrl(static_url('emp.json')).notify(this, this.didFetchContacts)
.send();
NOTE: This is not a javascript function. The compiler will replace this with the location of the file in the built app

system.io.directorynotfound -> But it works in Console

My files are referenced like so (it's all relative):
// WHERE YOU KEEP THE PAGE TITLE XML
public static string myPageTitleXML = "xml/pagetitles.xml";
and
using (StreamReader r = new StreamReader(myPageTitleXML))
{ //etc.. . .etc....etc..
}
I get system.io.directorynotfound, and "this problem needs to be shut down", when I double click the executable. But running it from the console works like a charm. What's wrong here?
I played around with attempting to set Environment.CurrentDirectory but couldn't get anything to work. Why should I have to do that anyway? It defeats the purpose of a relative path no?
responding.. .
"application" does not exist in the current context, i'll keep trying what people have mentioned, this is not a windows.form
testing
Path.GetDirectoryName(Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase), myPageTitleXML); gives error URI formats are not supported, as does Path.GetFullPath(). Server.MapPath results in an error as well, this is currently offline
Well assuming this directory is somewhere under the directory in which your code is executing, it sounds like you can use ..
Application.ExecutablePath()
or
Application.StartUpPath()
.. to get an idea as to what your application is seeing when it goes in search of an 'xml' directory with the 'pagetitles.xml' file in it.
If the directory returned by one of these methods does not point where you thought it did, you'll need to move the location of your application or the location of this folder so that it is within the same directory as the app.
Hope this gets you on the right path.
So, when you run it from double clicking the executable, is there a file named pagetitles.xml in a folder named xml, where xml is a folder in the same location as the executable?
It's certainly possible to use relative paths like this, but I wouldn't really recommend it. Instead, maybe use something like:
string fileToOpen = System.IO.Path.Combine(System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase), myPageTitleXML);
using (StreamReader r = new StreamReader(fileToOpen))
{
//etc.. . .etc....etc..
}
Is this ASP.NET code? If so then you probably need to do MapPath("xml/pagetitles.xml")
