blocks|key|1721535|text|预计您只会看到一个函数，它的名称是从index.js导出的。所有URL必须通过这个函数锚定。看起来，您希望/stats/*和/items/*都将通过您的函数进行路由，但这不是它的工作方式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1721536|如果您想要不同的路径前缀，您要么需要不同的函数来处理它们，要么您需要为它们设置一个单一的公共前缀。例如，您可以导出一个名为"api“的函数，然后使用它处理所有不同类型的查询：|1721537|/api/stats/...
/api/items/...|code-block|syntax|javascript|1721538|您还可以考虑对每个不同版本的api使用不同的函数(Express应用程序)，让Firebase将不同版本的应用程序路由到不同的应用程序，而不是让一个应用程序在运行时检查版本。|1721539|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

It's expected that you'll see only one function with the name you've exported from your index.js. All URLs must be anchored through that one function. It looks like you're expecting that both /stats/* and /items/* will route through your function, but that's not the way it works.

If you want different path prefixes, you will either need different functions to handle them, or you will need to have a single common prefix for them all. For example, you could export a function called "api", then use it to handle all the different types of queries:

<pre><code>/api/stats/...
/api/items/...
</code></pre>

You may also want to consider using different functions (Express apps) for each different version of your api, and have Firebase Hosting route the different versions to the different app, instead of having a single app check the version at runtime.

Each path can point to a distinct function (or Express app). You configure this in your <code>firebase.json</code> file like below. You don't need a separate domain at all. The below <code>firebase.json</code> results in

<code>
https://example.com is handled by firebase hosting
https://example.com/v1 is handled by firebase function
https://example.com/v2 is handled by firebase function
https://example.com/v3 is handled by firebase function
</code>

<pre><code>{
 "firestore": {
 "rules": "firestore.rules",
 "indexes": "firestore.indexes.json"
 },
 "hosting": {
 "public": "public",
 "cleanUrls": true,
 "trailingSlash": false,
 "rewrites": [
 {
 "source": "/v1",
 "function": "v1"
 },
 {
 "source": "/v2",
 "function": "v2"
 },
 {
 "source": "/v3",
 "function": "v3"
 }
 ],
 "ignore": [
 "firebase.json",
 "**/.*",
 "**/node_modules/**"
 ]
 },
 "storage": {
 "rules": "storage.rules"
 },
 "functions": {
 "source": "functions"
 }
}
</code></pre>

blocks|key|673062|text|最后，我用这样的方式解决了这个问题：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|673063|const+express+=+require("express")

const+getUserFunctions+=+express();
getUserFunctions.get("/stats",+(request,+response)+=>+{
++...
++...

});

const+v1+=+functions.https.onRequest(getUserFunctions);

module.exports+=+{
++v1,
++v2
};|code-block|syntax|javascript|673064|端点应该是这样的：|673065|https://xxxx.cloudfunctions.net/v1/stats|673066|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Finally, I solved it in this way:

<pre><code>const express = require("express")

const getUserFunctions = express();
getUserFunctions.get("/stats", (request, response) =&gt; {
 ...
 ...

});

const v1 = functions.https.onRequest(getUserFunctions);

module.exports = {
 v1,
 v2
};
</code></pre>

So the endpoint would be like this:

<pre><code>https://xxxx.cloudfunctions.net/v1/stats
</code></pre>

I am working with Firebase Cloud Functions and I am trying to versioning my api. I am using express as all the tutorials <a href="https://itnext.io/building-a-serverless-restful-api-with-cloud-functions-firestore-and-express-f917a305d4e6" rel="nofollow noreferrer">suggest</a>. However, with this solution, we use Firebase Hosting instead of Cloud Functions.

Hosting: <a href="https://xxxx.firebaseapp.com" rel="nofollow noreferrer">https://xxxx.firebaseapp.com</a>

Cloud Functions: <a href="https://xxxx.cloudfunctions.net" rel="nofollow noreferrer">https://xxxx.cloudfunctions.net</a>

The solution which comes closest to what I am looking for is <a href="https://codeburst.io/express-js-on-cloud-functions-for-firebase-86ed26f9144c" rel="nofollow noreferrer">this</a>  .

  

<pre><code>const app1 = express();
app1.use(cors({ origin: true }));
app1.get("*", (request, response) =&gt; {
 if(request.url.includes("/v1/")){
 response.send("V1: "+request.path);
 }
 else{
 response.send("V2: "+request.path);
 }

});

const stats = functions.https.onRequest(app1);

module.exports = {
 stats
};
</code></pre>

However, you only can see only one function in Firebase Cloud Functions:  

<pre><code>https://xxxx.cloudfunctions.net/stats
</code></pre>

Also, you only can handle one kind of HTTP request (GET, POST, etc). 

What I am looking for is to have in Firebase Cloud Functions:  

<pre><code>https://xxxx.cloudfunctions.net/stats/v1/ (including GET, POST, PUT or in another case separate functions with “/:userId” “/save”, etc)
https://xxxx.cloudfunctions.net/stats/v2/ 
https://xxxx.cloudfunctions.net/item/v1/
</code></pre>

Is it possible to do it with Cloud Functions?
