actually comes from the same thing. As long as it is not the first data to be loaded, there will be a color reminder, such as Ajax data

.

data.php 

<?php
$arr = [
        'errNo' => 0,
        'errstr' => 'success',
        'data' => [

                'list' => [],
        ]
];
header('Content-Type:application/json;');
echo json_encode($arr);

Front 

<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>
axios.get('/data.php')
  .then(function (response) {
    console.log(response.data);
  });
</script>

result

need to confirm what the content-type in response header is
