Question

在将角度应用部署到Firebase托管后，我无法从资产文件夹中加载图像。（build --prod）在本地主机上运行时，图像显示。其他所有东西都正确加载。这是我的包json cli：〜6.2.0-beta.2 firebase-tools：4.1.0

  }
}

在appComponent上尝试

<img src="../assets/image.jpg">
<img src="/assets/image.jpg">
<img src="assets/image.jpg">

没有这项工作。

firebase.json上的托管设置

"hosting": {
"public": "dist",
"ignore": [
  "firebase.json",
  "**/.*",
  "**/node_modules/**"
],
"rewrites": [
  {
    "source": "**",
    "destination": "/index.html"
  }
]

}

火力基地有招吗？重写？有人可以帮助我！

Answer 1

Firebase部署后，现在从角6.1.3中的资产加载图像！终于找到了解决方案，对我来说很好。问题是tsconfig.json更改：

"outDir": "./dist/out-tsc",

收件人：

"outDir": "./dist",

Answer 2

部署到Firebase托管后，即使静态资产在从localhost提供服务时也能正常工作，但静态资产也存在相同的问题。我必须换
<img src="/src/assets/img/pricing_comparison.PNG">至
<img src="/assets/img/pricing_comparison.PNG">。

（附言：我尝试根据接受的答案更改tsconfig.json文件，但这并没有更改或解决我的错误）

Answer 3

我也有同样的问题。这是我尝试过的解决方法

打开 tsconfig.json 更改：

"outDir": "./dist/out-tsc"，

收件人：

"outDir": "./dist"
打开 angular.json 。确保资产配置如下所示

       "assets": [
          "src/favicon.ico",
          "src/assets"
        ],

更改img标签<br> src="/src/assets/img/pricing_comparison.PNG"至<br> src="/assets/img/pricing_comparison.PNG"。

Answer 4

如果您在本地主机工作

只使用

这样的网址

#login {
    background-image: url('/assets/app-assets/img/gallery/login-bg.jpg');
    background-size: 100% 100%;
    background-repeat: no-repeat;
  }

在您的CSS或html组件中，这对我有用。只需将图像网址从/src/assets/your_image.png更改为/assets/your_image.png

这是我的棱角版本
