Your RestController.java is fine (only missing '}' ). There is actualy no ajax call from your index.html.
It can look somethink like that:
<!DOCTYPE html>
<html>
<head>
<script>
function callAPI() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
console.log(this.responseText)
}
};
xhttp.open("GET", "/api/hello", true);
xhttp.send();
}
</script>
</head>
<body>
<button onClick="callAPI()">Click me</button>
</body>
</html>
Depending on your particular environment you still might need to update the API URL in javascript or enabling CORS. Check these links

I'm using JS-Cookie for setting a Cookie via the front-end.
Why can't I access it in my Laravel 5.8 application with:
dd(request()->cookies)? The Cookie is visible with the name, but the value is null. But when I do try to get the Value of the Cookie via the "normal" way, I do get the value: dd($_COOKIE['the-cookie-value-i-want']);.
How can I access the value of the Cookie via the "Laravel-way"? Which is more secure.
I know this is an old question, but you can disable encryption for specific cookies instead of disabling it for everything (which would break secure sessions).
Edit the \App\Http\Middleware\EncryptCookies class to include the following:
/**
* The names of the cookies that should not be encrypted.
*
* #var array
*/
protected $except = [
'my_frontend_cookie_name'
];
You can now access the cookie value via request()->cookie() or the Cookie::get() facade.
Only cookie created by laravel can handle by laravel.
Now here is the way you can achieve this
Go to : app > Http > Kernal.php : under $middlewareGroups array comment this
'web' => [
//\App\Http\Middleware\EncryptCookies::class,
And then try
Here is the demo
<!doctype html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Laravel</title>
</head>
<body>
{{ Cookie::get('cookie1') }}
{{ request()->cookie('cookie1') }}
<script type="text/javascript">
document.cookie = 'cookie1=test; path=/'
</script>
</body>
</html>
Lets say I have a website "example.com". I call the following line
// Pass html content of the site.com to a string
string htmlCode = client.DownloadString("http://example.com");
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(WebUtility.HtmlDecode(htmlCode));
For some websites I have the exact html I want. But some sites return a html consist of forms, or with an empty body and some kind of scripts.
Example for script one:
<!DOCTYPE html>
<html><head>
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Expires" content="-1">
<meta http-equiv="CacheControl" content="no-cache">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="shortcut icon" href="data:;base64,iVBORw0KGgo=">

How can I deal with this "ecnryption" system and get the final html I want that is on "example.com", that you see when you check the source on the browser?
Do you have a F5 Server in front of your webserver? Because I have a similar situation, where that Javascript gets injected in my code (which leads to problems).
This was due to page loading with an AJAX call. It could be solved by using PhantomJS web driver.
I try to parse HTML using HtmlAgilityPack using simple doc.load method by passing the URL, but it comes with the following result how can I resolve this issue?
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

exdate.setDate(exdate.getDate()+expiredays);

expires=" + exdate.toGMTString()) + ";path=/"; }
function getHostUri()

This Message says it all, the side needs javascript to be loaded, and HtmlAgilityPack is no JavascriptEngine!
The Load Method of the HtmlDocument can not interpret and execute Javascript-Code it´s just a simple "Download"-Function for static HTML-Sites.
What you could try to do is, with Firebug (or something else) check which HttpRequest are made to get the content, and this Requests you have to recreate in C# to get the HTML you want!

this is my situation. I'm writing an webinterface in codeigniter to send commands to a virtual server. these commands are passed through the browser in an url.
example : http://server.com/TgtSendIRCommand?id=UM-02&code=KEY_UP
this server then takes action and the web interface refreshes the screenshot.
i just want to have a bunch of links in html that send this command to the browser.
But if i click the links, the user has to stay on the same page. So the command is sended but there is no other interaction.
i am using codeigniter.
Any suggestions ?
Make a view and copy this in your view:
<html>
<head>
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js" type="text/javascript"></script>
</head>
<body>
Click here!
<script type="text/javascript">
$(document).ready(function(){
$("#myBtn").click(function(){
$.get("http://server.com/TgtSendIRCommand?id=UM-02&code=KEY_UP ");
});
});
</script>
</body>
</html>
Not tested but something as above should do the trick for you.
<?php
session_start();
$_SESSION['http://localhost/profile.php'] = $_SERVER['REQUEST_URI'];
$sess=$_SESSION["email"];
$servername = "localhost";
$username = "root";
$password = "";
$dbname ="reg";
if(!isset ($sess))
{
header("Location:login.php");
exit;
}
