now some files in the project have to be introduced into index.html, and most mobile phone tests are fine, but when Android 5.1 was tested, it was found that the files introduced in index.html did not work.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=0,minimum-scale=1, maximum-scale=1" />
<meta content="telephone=no" name="format-detection" />
<link rel="stylesheet" href="/static/css/shop.css">
<title>shop</title>
</head>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
<script src="./static/js/config.js"></script>//5.1
<script src="./static/js/jquery-3.2.1.min.js"></script>
<script src="./static/js/jshop.min.js"></script>
</body>
</html>
adding printing to the file will not print it out, and the page will report an error
config is full of configuration items, there is nothing complicated
var config= {};
config.api = "";
config.url = ";
//
config.login = "";
config.apia = "";
