我已经构建了一个快速应用程序,文件夹结构如下。

as follows

然后我在一个虚拟文件夹上创建了 firebase init 托管并复制了 firebase.json 和 .firebase 文件

我创建了 index.js 文件

    const functions = require('firebase-functions')
const app = require('./app');
exports.widgets = functions.https.onRequest(app);

firebase.json
{
"hosting": {
"public": "public",
"rewrite":[{
"source": "**",
"function": "widgets"
}],
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
]
}
}

还将firebase生成的index.html复制到公共(public)文件夹

在部署我得到 index.html

如果我删除 index.html 并作为 localhost 运行,我将低于输出

如何在 firebase deploy 上执行 express 应用程序(如 localhost 所示)而不是 index.html。

我关注 link .

当我运行 火力基地服务 ,我收到此错误
AssertionError [ERR_ASSERTION]: missing path at Module.require (module.js:583:3) at require (internal/module.js:11:18) at InitializeFirebaseAdminStubs (C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:231:18) at C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:451:9 at Generator.next () at C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:7:71 at new Promise () at __awaiter (C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:3:12) at main (C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:421:12) at Object. (C:\Users\alaksandarjesus\AppData\Roaming\npm\node_modules\firebase-tools\lib\emulator\functionsEmulatorRuntime.js:511:5)

当我尝试运行 火力基地部署
E:\ogst-server-firebase\functions>firebase deploy

=== Deploying to 'ogst-server-95fcc'...

i deploying functions, hosting
i functions: ensuring necessary APIs are enabled...
+ functions: all necessary APIs are enabled

Error: An unexpected error has occurred.

原因是缺少公用文件夹,并且我手动创建了(预计将使用 firebase init 函数创建)。
E:\ogst-server-firebase\functions>firebase deploy

=== Deploying to 'ogst-server-95fcc'...

i deploying functions, hosting
i functions: ensuring necessary APIs are enabled...
+ functions: all necessary APIs are enabled
i functions: preparing functions directory for uploading...
i hosting[ogst-server-95fcc]: beginning deploy...
i hosting[ogst-server-95fcc]: found 0 files in public
+ hosting[ogst-server-95fcc]: file upload complete

+ hosting[ogst-server-95fcc]: version finalized
i hosting[ogst-server-95fcc]: releasing new version...
+ hosting[ogst-server-95fcc]: release complete

+ Deploy complete!

Please note that it can take up to 30 seconds for your updated functions to propagate.
Project Console: https://console.firebase.google.com/project/ogst-server-95fcc/overview
Hosting URL: https://ogst-server-95fcc.firebaseapp.com

现在我的部署成功了。但我得到 404

回答
在 index.js 文件中(按照上面的链接),我没有改变
module.exports = functions.https.onRequest(app); //wrong

to

exports.app = functions.https.onRequest(app); //correct

感谢大家的支持

最佳答案

Firebase 托管更喜欢提供静态内容,而不是发送到 Cloud Functions 的重写。换句话说,如果请求可以由任何静态内容提供服务,则该内容将始终优先于对 Cloud Functions 的重写。

如果您希望 Cloud Functions 为您的网站根页面提供服务,这意味着您的公共(public)文件夹中不应该有 index.html,因为 Firebase Hosting 会首先找到它。
