javascript - Can not get data from AJAX request to the Coinhive API

819

I recently tried to get the data from a Json API and post that back to a table in html. I tried to do this from:https://api.coinhive.com/user/balance?name=username&secret=mysecret It does show me:{"success":true,"name":"*user*","total":49152,"withdrawn":0,"balance":* a value *}

But I want to let my users push a button which will load the balance value to a table in their own user portal.

I got the user portal setup with all the mysqlvalues, But i can't manage to get the jsonpart to work.

Can anyone please help me?

Thanks in common, Dennis.

edit:

I tried the following:

<html lang="en">
<head>
<title>JavaScript - read JSON from URL</title>
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
</head>

<body>
    <div class="mypanel"></div>

    <script>
    $.getJSON('https://api.coinhive.com/user/balance?name=username&secret=mysecret', function(data) {

        var text = `Balance: ${data.balance}<br>`


        $(".mypanel").html(text);
    });
    </script>

</body>
</html>

And I also tried:

function setup() {
    loadJSON("https://api.coinhive.com/user/balance?name=username&secret=mysecret", gotData);
}

function gotData(data) {
    alert(data);
}

And that isn't working. What am I doing wrong?

Solution:

figured it out!

The JSON request:

<?php
$url = 'the api url';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  "Content-Type: application/x-www-form-urlencoded"
));

$data = curl_exec($ch);
curl_close($ch);

$result = json_decode($data, true);

?>

The postback to the end user:

<span id="test" class="page_speed_1728654869"><?php
if (isset($data))
{
   echo $result['balance'];
}
else
{
   echo 'damn';
}
?></span>

I decided to go with php and kind of ditch the html getjson part.

Solution:

Client side requests to the Coinhive HTTP API are restricted by CORS rules:

From API documentation:

You should never call the Coinhive HTTP API from the client side.
