【中文标题】在 index.html 上添加清单 Json【英文标题】:Adding Manifest Json on index.html 【发布时间】:2021-05-04 06:31:05 【问题描述】:

我正在尝试在 Angular 上实现 firebase 通知。但是,当我在 src/ 添加 manifest.json 并在 index.html 中将其引用为 <link rel="manifest" href="./manifest.json"> 但是浏览器给了我两个错误 404 not found 和 清单:行:1,列:1,语法错误 当我用 dom 检查它并通过一个新选项卡打开它时,它被重定向到我的索引而不加载资源我尝试了一些解决方案,但它们似乎都不起作用。当我在索引上评论该行时,错误似乎才消失。 我目前正在使用角度版本 7.1.0

【问题讨论】:

【参考方案1】:

您好像错过了将其添加到angular.json 文件中。

确保您的 angular.json 结构包含 manifest.json 文件。


  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "newProjectRoot": "projects",
  "projects": 
    "project-name": 
      "root": "",
      "sourceRoot": "src",
      "projectType": "application",
      "architect": 
        "build": 
          "builder": "@angular-devkit/build-angular:browser",
          "options": 
            ...
            "assets": [
              "src/assets",
              "src/favicon.ico",
              "manifest.json"  // <-- Must be included
            ],
          ...

【讨论】:

我已经在 angular.json 上添加了它,它位于 src/manifest.json 目录中,但它似乎不起作用。由于错误不会消失 你能分享你的angular.jsonmanifest.json文件吗? 请看我上面分享的内容【参考方案2】:

    将 src/manifest.json 添加到 angular.json 中的 assets 数组中 "assets": ["src/assets", "src/favicon.ico", "src/manifest.json"],

    重启你的服务器
