如何在 firebase 托管和功能中配置重写和映射前缀动态路由路径？

Question

我启用了 firebase 页面和功能。我想要一个 api 路线，如下所示：

1. https://mmydomain.com/api/generatorPerson
2. https://mmydomain.com/api/generateLead
3. https://mmydomain.com/api/and_so_on

我确实遵循了 Firebase 团队 https://youtu.be/LOeioOKUKI8 (Dynamic Node apps) in which he mapped or hooked the path https://mmydomain.com/timestamp 的这个指南到 firebase 函数 'exports.app' 他有 /timestamp 快速路由路径.他的代码类似于下面的代码：

functions/index.json

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

const app = express();

app.get('/timestamp', (request, response) =>{
    response.send('${Date.now()}');
});

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

public/firebase.json

{
  "hosting": {
    "public": "public",
    "rewrites": [
      {
        "source": "/timestamp",
        "function": "app"
      }
    ]
  }
}

现在我的目标有点相同，但我想在路径前加上 'api' 前缀，这样我就可以拥有上面列出的 api 路径。我尝试首先使用下面的函数 setup/config 和 firebase 配置来处理 https://mmydomain.com/api/generatorPerson。它部署没有错误，但我收到 404 错误。

functions/index.json

const faker = require('faker');
const express = require('express');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();

const app = express();

app.get('/api/generatePerson', (request, response) =>{
    let randomName = faker.name.findName();
    let randomEmail = faker.internet.email();
    let randomPhoneNumber = faker.phone.phoneNumber();
    let randomBirthDay = faker.date.past();
    let randomAddress = faker.address.streetAddress();
    let randomJobTitle = faker.name.jobTitle();
    let randomJobDescription = faker.name.jobDescriptor();
    let randomCompany = faker.company.companyName();

    let person = {
        name: randomName,
        email: randomEmail,
        phoneNumber: randomPhoneNumber,
        birthday: randomBirthDay,
        address: randomAddress,
        work: {
            jobTitle: randomJobTitle,
            jobDescription: randomJobDescription,
            company: randomCompany
        }
    };

    response.send(person);
});

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

public/firebase.json

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

我使用模式 /api/** 因为我希望所有子路由都以 api 为前缀并将它们映射到 exports.app。我的代码有什么问题？还是我写错了前缀？

Answer 1

尝试

app.get('/generatePerson', (request, response) =>{

/api 已经映射到 Express 应用

Answer 2

我通过以下方式解决了问题：

1. 清理了 firebase.json 的任何评论工件。
2. 同时部署托管和函数。
3. 如果问题仍然存在，请等待几分钟或刷新 API 的 http 调用。之后就可以了。
