使用NodeJS在firebase托管中分离路由

Question

我想使用Node.js在firebase宿主中分离/创建路由。我创建了两个JS文件：apiservice.JS和service.JS，它们包含firebase云函数。

apiservice.js文件包含与API请求相关的路由。services.js文件包含与正常使用请求相关的路由。当我运行此代码时，将出现以下错误：

无法获取/firebaseproject id/us-central1/app/api/

代码如下：

apiservice.js:

const functions = require('firebase-functions');
const express = require("express");
const app = express();
app.get("/api/login", (req, res) => {
//code
});
app.get("/api/signup", (req, res) => {
//code
});
exports.apiservice = functions.https.onRequest(app);

service.js:

const functions = require('firebase-functions');
const express = require("express");
const app = express();
app.get("/signup", (req, res) => {
//code
});
app.get("/login", (req, res) => {
//code
});
exports.service = functions.https.onRequest(app);

firebase.json:

{
"hosting": {
"public": "public",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [{
"source": "/api",
"function": "apiservice"
},
{
"source": "/",
"function": "service"
}]
},
"functions": {
"predeploy": [
"npm --prefix "$RESOURCE_DIR" run lint"
]
}
}

任何帮助都将不胜感激。非常感谢。

Answer 1

我找到了一个解决方案。我没有在index.js文件中导入apiservice和service。因此，路由不起作用。所以，我稍微修改了一下代码，并在index.js文件中添加了几行。我从这里得到了参考：如何在Express中的多个文件中包含路由处理程序？

因此，更新后的工作代码是：

apiservice.js:

const functions = require('firebase-functions');
const express = require("express");
let apirouter = express.Router();
apirouter.get("/api/signup", (req, res) => {
//Code
});
module.exports = apirouter;

service.js:

const functions = require('firebase-functions');
const express = require("express");
let router = express.Router();
apirouter.get("/signup", (req, res) => {
//Code
});
module.exports = router;

index.js:

const functions = require('firebase-functions');
const express = require("express");
const apisrcrouter = require("./apiservice");
const srcrouter = require("./service");
let app = express();
app.get("/api/**", apisrcrouter);
app.get("/**", srcrouter);
module.exports = {
'apisrcrouter': functions.https.onRequest(apisrcrouter),
'srcrouter': functions.https.onRequest(srcrouter)
};

firebase.json:

{
"hosting": {
...
"rewrites": [
{
"source": "/api/**",
"function": "apisrcrouter"
},
{
"source": "/**",
"function": "srcrouter"
}]
...
}
