为 VueJS 应用实现一个 manifest.json 文件来设置条件

Question

我已经在我的 Vue 应用程序中添加了一个 manifest.json 文件。这个文件位于一个名为 scripts 的文件夹中，然后在我的 main.js 上引用该文件夹。但是，它真的什么也没做。例如，我将其设置为将显示设置为独立，将方向固定为纵向，并在用户将其添加到浏览器中的书签时添加标题和书签图标。不幸的是，由于某种原因，它似乎根本不起作用。我哪里做错了？

manifest.json 如下所示

{
  "name": "Bake Bread App",
  "short_name": "Breadr",
  "theme_color": "blue",
  "background_color": "blue",
  "display": "standalone",
  "orientation": "portrait",
  "Scope": "/",
  "start_url": "/",
  "icons": [
    {
      "src": "/assets/bookmark-icons/icon-72x72.png",
      "sizes": "72x72",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-96x96.png",
      "sizes": "96x96",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-128x128.png",
      "sizes": "128x128",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-144x144.png",
      "sizes": "144x144",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-152x152.png",
      "sizes": "152x152",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-192x192.png",
      "sizes": "192x192",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-384x384.png",
      "sizes": "384x384",
      "type": "image/png"
    },
    {
      "src": "/assets/bookmark-icons/icon-512x512.png",
      "sizes": "512x512",
      "type": "image/png"
    }
  ],
  "splash_pages": null
}

然后，如果我们上升一个级别（从这个脚本文件夹之外）并进入main.js，我有

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
Vue.config.productionTip = false;
// FILTERS
Vue.filter('snippet', function(value) {
    return value.slice(0,100);
});
Vue.component('loading-screen', {
  template: '<div id="loading">Loading...</div>'
});
import json from './scripts/manifest.json'
export default{
    data(){
        return{
            myJson: json
        }
    }
}
new Vue({
  router,
  store,
  render: h => h(App),
}).$mount("#app");

此外，我按照 Google 开发者文档的说明.html在索引中添加了<link rel="manifest" href="js/manifest.json">。

它在 Vue 中不起作用的原因img src neds 在 Data object 中定义 require()

webpack 需要了解这些图像。

• 沙盒

• 您可以修改清单并对资源使用 getter 函数。

• 或者，可以在数据对象中use require("path to the resource (not the manifest string)")。

helloWorld.vue：

 <template>
    <div class="hello">
    <h1>{{ msg }}</h1>
    <ol v-for="x in myJson.icons" :v-bind="x" :key="x">
      <li>
      <div> name: {{x.name}}</div>
      <div> name: {{x.sizes}}</div>
      <div> name: {{x.type}}</div>
      <img :src="getSrc(x.src)" alt="wrong..">
      </li>
    </ol>
  </div>
</template>
<script>
import json from "../../manifest.json";
export default {
  name: "HelloWorld",
  data() {
    return {
      myJson: json,
      msg: "Manifest:"
    };
  },
  methods: {
    getSrc(src) {
      return require("../assets/" + src);
    }
  }
};
</script>

修改后的图标 json：

  "icons": [
    {
      "name": "logo",
      "src": "logo.png",
      "sizes": "99x99",
      "type": "image/png"
    },
    {
      "name": "logo2",
      "src": "logo.png",
      "sizes": "929x929",
      "type": "image/png"
    }
  ],
