Question

我开发了一个nodejs应用程序，可以将HTTP / HTTPS链接转换为种子。在localhost上运行正常。当我将其上传到Firebase托管时。它不起作用。它甚至可以在我使用的Firebase localhost上运行。我该如何解决。

firebase serve命令

，但是当我将其部署到Firebase服务器时，它会显示索引页面。但它不起作用。

下面是我的源代码。

主文件夹中的
firebase.json 文件

{
  "hosting": {
    "public": "./public/html",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      
      {
        "source": "/?thelink=",
        "destination": "app"
      },
      {
        "source": "/l?thelink=",
        "destination": "app"
      },
      {
        "source": "/",
        "destination": "app"
      }
    ]
  }
}

index.js 在功能文件夹上

const functions   = require('firebase-functions');

         res.send(buffer);
         console.log(fileName+'.torrent created');
         res.end();
         //-------------------------------------------

    }
    else{
      console.log('More than 500 MB');
      res.send("<h4> More than 500 MB or invalid URL </h4>");
    }

app.listen(port);

console.log('server up and running', port);

exports.app = functions.https.onRequest(app)

index.html 在文件夹public / html
