I have a loader function called getBlogData which is like this:
import { getFromCacheOrApi } from 'Base'
const getBlogData = async () => {
const { pathname } = { pathname: "" }
var url = '/blog/data?'
let matches = /\/blog(\/\d+)?\/?$/.exec(pathname)
if (matches != null) {
const pageNumber = matches[1]
if (pageNumber !== undefined) {
url += `&pageNumber=${pageNumber.replace('/', '')}`
}
}
else {
const secondSegments = ['category', 'tag', 'author', 'search']
if (pathname.split('/').length >= 2 && !secondSegments.includes(pathname.split('/')[2])) {
response.status = 404
return
}
for (let i = 0; i < secondSegments.length; i++) {
const segment = secondSegments[i]
if (pathname.startsWith(`/blog/${segment}`)) {
matches = new RegExp(`(?<=\\/blog\\/${segment}\\/)[^/]+\\/?(\\d+)?\\/?$`).exec(pathname)
if (matches == null) {
response.status = 404
return
}
else {
url += `&${segment}=${encodeURI(matches[0].split('/')[0])}`
const pageNumber = matches[1]
if (pageNumber !== undefined) {
url += `&pageNumber=${pageNumber}`
}
break
}
}
}
}
url = url.replace('?&', '?')
const data = await getFromCacheOrApi(url)
// console.log(params, response.status)
// if (pageNumber && isNaN(pageNumber)) {
// console.log(pageNumber, isNaN(pageNumber))
// response.status = 400
// return
// }
const { seoParameters } = data
return data
}
export default getBlogData
This function is only used in my page which is inside app directory in Next 13, which means that it's a server component, and I don't want to change it to a client component.
However, I need to access request data, in this particular case, the path of the URL.
How can I get that?

Above is the function which I've used in order to access the webcam of the system. It work fine when i use it on localhost but the problem arises when the same is put on the server and then accessed through intranet.
I'm unable to find the reason to fix it. Kindly help me with the same.
The first two images are the ones when i use my code on localhost. It works fine as i'm able to access the webcam.
Problem statement:
The last image is the one where I try to do the same through server. The webcam opens by the images is completely wiped out. Only a white screen appears and even if I capture the photo through webcam, the white image is only saved on server instead of a proper original image.
Because of security reasons you have to serve the Site over Https to access the camera.
I have used the azure media player with my project, it will play multiple adaptive bit rate streamed videos in an asp.net page, the best part is, it is working superb in html5 and flash but it will get stuck at spinner image in silverlight fallback.
Below is the code I have used.
I have also tried to get errors but it is not hitting the event listener code added for errors, but the play and pause events are working fine where flash and html5 is used, but silverlight fallback is not working at all.

Updated
Noticed I am getting following error for IE < 11.
Also I disabled the flash in firefox and removed the silverlight from techOrder, then it should hit the error event listener, it is not hitting.
This is also important for me to handle the analytics for error.
Play and Pause event listener are working fine.
Update 8/28/2015:
Fixed the JS error, it is because of multiple call to cdn of azure mentioned in link above, moved the code in master page and load it only once, browser like chrome handles duplicity of code easily but not IE.
After all the research I am lost why it is not working.
So added the following JS that will check for Silverlight and Flash and gracefully handle the error and update our analytics as well.
function getBrowserInformation() {
var ua = navigator.userAgent, tem, M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
if (/trident/i.test(M[1])) {
tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
return { name: 'IE ', version: (tem[1] || '') };
}
if (M[1] === 'Chrome') {
tem = ua.match(/\bOPR\/(\d+)/)
if (tem != null) { return { name: 'Opera', version: tem[1] }; }
}
M = M[2] ? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?'];
if ((tem = ua.match(/version\/(\d+)/i)) != null) { M.splice(1, 1, tem[1]); }
return {
name: M[0],
version: M[1]
};};
function checkForAzureErrors() {
function isSilverlightInstalled() {
var isSilverlightInstalled = false;
try {
//check on IE
try {
var slControl = new ActiveXObject('AgControl.AgControl');
isSilverlightInstalled = true;
}
catch (e) {
//either not installed or not IE. Check Firefox/Safari
if (navigator.plugins["Silverlight Plug-In"]) {
isSilverlightInstalled = true;
}
}
}
catch (e) {
console.log(e);
}
return isSilverlightInstalled;
}
function isFlashInstalled() {
try {
return Boolean(new ActiveXObject('ShockwaveFlash.ShockwaveFlash'));

}
}
function addErrorMessage() {

}
function checkBrowser() {
if ((getBrowserInformation().name === 'MSIE' || getBrowserInformation().name === 'IE')) {

}

if (isSilverlightInstalled()) {
if (!amp.players[key].isReady_) {
checkBrowser();
}
} else if (!isFlashInstalled()) {
checkBrowser();
}
}
}}
This function is called after 5 second of page load in document.ready function, giving it enough time to load and make the isReady_boolean true.
SetTimeout(function () { checkForAzureErrors(); }, 5000);
Still I am waiting for some angel to resolve this issue.
Updates: Partially Fixed
Need to add the xap refrences like older version, it will play silverlight but there is a catch, it will only work if you have one video per page.

As per comments from Amit Rajput
#Parshii Currently, as per the documentation, Azure Media Player doesn't support multi-instance playback. While it may work on some techs, it is not a tested scenario at this time. Please feel free to add it to the UserVoice forum (http://aka.ms/ampuservoice).
As per my testing it is working in html5 and flash but not Silverlight, for silverlight support we can try using iframes as per comments from rnrneverdies
Single Instance Media Player is working in all techs.

This may be not a complete answer, but could help you.

In previous versions of angularFire, it was possible to secure selected routes by using "authRequired" and "pathTo" with Angular's $routeProvider. These no longer appear to work with AngularFire 0.6.0. What is the equivalent parameter/technique in Angular 0.6.0?
Routing was moved out of angularFire for the same reasons it was moved out of the core of Angular--to be less opinionated in how routing is conducted and which lib you should use.
You can still include routing by grabbing the module from angularFire-seed, which is plug-and-play ready.
The steps are:
add ngRoute and routeSecurity to your app dependencies
declare the loginRedirectPath constant
add authRequired where appropriate
Example:
// add routeSecurity to your dependency libs
angular.module('myApp', [..., 'ngRoute', 'firebase', 'routeSecurity']);
// declare the loginRedirectPath variable
angular.module('myApp').constant('loginRedirectPath', '/login')
// put authRequired in your routes
$routeProvider.when('/account', {
authRequired: true, // must authenticate before viewing this page
templateUrl: 'partials/account.html',
controller: 'AccountCtrl'
});
// live long and prosper
Here's a hard copy of the module as of 0.6.0 for compliance with SO policy; refer directly to the source for a current version:
(function(angular) {
angular.module('routeSecurity', [])
.run(['$injector', '$location', '$rootScope', 'loginRedirectPath', function($injector, $location, $rootScope, loginRedirectPath) {
if( $injector.has('$route') ) {
new RouteSecurityManager($location, $rootScope, $injector.get('$route'), loginRedirectPath);
}
}]);
function RouteSecurityManager($location, $rootScope, $route, path) {
this._route = $route;
this._location = $location;
this._rootScope = $rootScope;
this._loginPath = path;
this._redirectTo = null;
this._authenticated = !!($rootScope.auth && $rootScope.auth.user);
this._init();
}
RouteSecurityManager.prototype = {
_init: function() {
var self = this;
this._checkCurrent();
// Set up a handler for all future route changes, so we can check
// if authentication is required.
self._rootScope.$on("$routeChangeStart", function(e, next) {
self._authRequiredRedirect(next, self._loginPath);
});
self._rootScope.$on('$firebaseSimpleLogin:login', angular.bind(this, this._login));
self._rootScope.$on('$firebaseSimpleLogin:logout', angular.bind(this, this._logout));
self._rootScope.$on('$firebaseSimpleLogin:error', angular.bind(this, this._error));
},
_checkCurrent: function() {
// Check if the current page requires authentication.
if (this._route.current) {
this._authRequiredRedirect(this._route.current, this._loginPath);
}
},
_login: function() {
this._authenticated = true;
if( this._redirectTo ) {
this._redirect(this._redirectTo);
this._redirectTo = null;
}
else if( this._location.path() === this._loginPath ) {
this._location.replace();
this._location.path('/');
}
},
_logout: function() {
this._authenticated = false;
this._checkCurrent();
},
_error: function() {
if( !this._rootScope.auth || !this._rootScope.auth.user ) {
this._authenticated = false;
}
this._checkCurrent();
},
_redirect: function(path) {
this._location.replace();
this._location.path(path);
},
// A function to check whether the current path requires authentication,
// and if so, whether a redirect to a login page is needed.
_authRequiredRedirect: function(route, path) {
if (route.authRequired && !this._authenticated){
if (route.pathTo === undefined) {
this._redirectTo = this._location.path();
} else {
this._redirectTo = route.pathTo === path ? "/" : route.pathTo;
}
this._redirect(path);
}
else if( this._authenticated && this._location.path() === this._loginPath ) {
this._redirect('/');
}
}
};
})(angular);
creating service
myApp.factory('serviceHttp', ['$http', function(http) {
http.get($scope.url).then(function(result){
serviceVariable = result;
}
return serviceVariable;
}
Controller
function appController($scope, serviceHttp){
$scope.varX = serviceHttp;
if(serviceHttp){
// decision X;
} else {
// decision Y;
}
}
view:
input(ng-if='varX') serviceHttp Exist
input(ng-if='!varX') serviceHttp noExist
The above code always shows varX not exist because app installs during http call of service. I want to use angular service to inject variables from server to make decision at time of booting the application.
Try to rewrite factory by this way that returns promise:
myApp.factory('serviceHttp', ['$http', function(http) {
var factory = {
query: function () {
var data = http.get($scope.url).then(function(result){
return result;
},
function (result) {
alert("Error: No data returned");
});
return data;
}
}
return factory;
}]);
From controller:
serviceHttp.query().then(function (result) {
$scope.varX = = result;
}
Here is Demo Fiddle
in demo we used other URL source
If i correct understand you, you should doing it like this:
var app = angular.module('YourModule', []);
app.factory("serviceHttp", function($http) {
var serviceHttp={};
serviceHttp.yourGetRequest = function(yourUrl) {
return $http.get(yourUrl);
};
return serviceHttp;
});
And for example, controller:
var Controller = function($scope,serviceHttp) {
$scope.varX='';
$scope.loading = true;
var returnArr = serviceHttp.yourGetRequest($scope.url).success(function(dataFromServer) {
$scope.loading = false;
$scope.varX = dataFromServer;
})
};
in view you can use ng-show, like this:
<div ng-show="loading" class="loading"><img src="../styles/ajax-loader-large.gif"></div>
When your application start loading, $scope.loading = true and this div shown, and when you get response from server $scope.loading became false and div doesn't show.
