Good morning,
In my work, a biometric reader system was implemented to control the exit and entry of personnel. Such a system has an API that gives access to your data. Every API is in Ajax with JQuery. I looked at W3Schools on link and learned how to do that. This is the API code:
$.ajax({
url: "/login.fcgi",
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({
login: 'admin',
password: 'admin'
}),
success: function(data) {
session = data.session;
}
});
So I did the following HTML:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script><script>$(document).ready(function(){$("button").click(function(){
$.ajax({
url: "http://10.3.48.199/login.fcgi",
type: 'POST',
contentType: 'application/json',
data: JSON.stringify({
login: 'admin',
password: 'admin'
}),
success: function(data) {
session = data.session;
}
});
});
});
</script>
</head>
<body>
<button>Teste</button>
</body>
</html>
However, when I click the button, it, on the console, gives me errors of CORS . I searched the internet and added the following line below the url line: "Access-Control-Allow-Origin: *," . This removed the CORS error. But, I can not access the server. No error appears. Also no message appears. I already tried to give alert to see if the session appeared, but also nothing. Can someone help me? Maybe it's code semantics error.
