我正在使用PHP。我想要功能性“添加到主屏幕”。我读了一些博客，编写了一些代码，但仍然不起作用

我的文件结构如下：

我的index.html是：

<!DOCTYPE html>
<html>
<head>
    <title>Template One</title>
    <link rel="manifest" href="/manifest.json">
</head>
<body>
    <div class="mainContainer template1">
        hello
    </div>
 </body>

 <script>
 if ('serviceWorker' in navigator) {
 console.log("Will the service worker register?");
 navigator.serviceWorker.register('service-worker.js')
  .then(function(reg){
    console.log("Yes, it did.");
 }).catch(function(err) {
    console.log("No it didn't. This happened:", err)
});
}
</script>
</html>

service-worker.js为空。

当我在chrome上重新加载时。它不起作用

我走对了吗。请给出解决方案
