Question

我将Firebase功能host设置为在用户访问Firebase托管URL时运行，但是没有任何记录（该功能未被触发）

index.js：

exports.host = functions.https.onRequest((req, res) => {
  console.log(">>>> FUNCTION TRIGGERED!")
  res.send(">>>> GOT IT")
})

我在firebase.json中进行了设置：

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

这是我在本地运行时的仿真器功能日志（仿真器在localhost:4001上运行，而Web应用程序在localhost:5000上运行。当我访问localhost:5000时，没有任何日志记录，即使据说该函数已初始化。

这是设置功能的正确方法吗？这是我第一次与他们合作，所以我很难调试它。在某些情况下，我试图根据URL动态修改OpenGraph元标记，而我正在遵循本教程：https://medium.com/@jalalio/dynamic-og-tags-in-your-statically-firebase-hosted-polymer-app-476f18428b8b

Answer 1

您的主机重写看起来不正确。我建议您查看有关如何configure a rewrite to a function的文档。它不应该有“目标”，而应该只有“源”和“功能”。另外，如果您打算通过该函数提供URI“ /”，则公用文件夹中根本不应存在index.html，否则它将首先提供。

Firebase函数onRequest不触发
