Google 云函数没有被触发

Question

我试图在到达我的托管网站的路径时触发 google 云功能。

所以，我在我的 firebase.json

中添加了这个

"rewrites": [
  {
    "source": "**",
    "destination": "/index.html",
    "function": "app"
  }

这是我的函数 "app"：

[...]
server.get('*', (req:any,res:any) => {
 const isBot = detectBot(req.headers['user-agent']);

 if(isBot) {
     const botUrl = generateUrl(req);

     nf(`${renderUrl}/${botUrl}`)
     .then((r: { text: () => any; }) => r.text())
     .then((body: { toString: () => any; }) => {
         res.set('Cache-Control', 'public, max-age=300, s-maxage=600');
         res.set('Vary','User-Agent');
         res.send(body.toString())
     });
 } else {
    nf(`https://${appUrl}`)
    .then((r: { text: () => any; }) => r.text())
    .then((body: { toString: () => any; }) => {
        res.send(body.toString());
    });
 }


});


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

"app" 功能和网站已部署，但当我到达 url "app" 函数不会被触发。

提前致谢。

您的 "rewrites" 部分设置不正确。您指定目标（“/index.html”）和函数参数。这是一个重写示例，它将把对 /function-url 的请求定向到您的 app 函数，并将其他请求（未定义或“/foo”和“/foo/**”）定向到您的 index.html:

"rewrites": [ {
    // Serves index.html for requests to files or directories that do not exist
    "source": "**",
    "destination": "/index.html"
  }, {
    // Serves index.html for requests to both "/foo" and "/foo/**"
    // Using "/foo/**" only matches paths like "/foo/xyz", but not "/foo"
    "source": "/foo{,/**}",
    "destination": "/index.html"
  }, {
    // calls your app function for requests to "/function-url"
    "source": "/function-url",
    "function": "app"
  } ]
