Firebase Cloud Function Set Timeout 540s 但以 60s 结束

Question

我有我的云功能

import * as functions from 'firebase-functions';
const runtimeOpts = {
    timeoutSeconds: 540,
    memory: "1GB" as "1GB"

}
...
export const helloWorldAllowCORS = functions.runWith(runtimeOpts).https.onRequest(async (request, response) => {

    response.set('Access-Control-Allow-Origin', '*');
    response.set('Access-Control-Allow-Credentials', 'true'); // vital

    response.set('Keep-Alive', 'timeout=5, max=1000');

    if (request.method === 'OPTIONS') {
        // Send response to OPTIONS requests
        response.set('Access-Control-Allow-Methods', 'GET');
        response.set('Access-Control-Allow-Headers', 'Content-Type');
        response.set('Access-Control-Max-Age', '3600');
        response.status(204).send('');
    } else {
        let run = async (ms: any) => {
            await new Promise(resolve => setTimeout(resolve, ms));
        }
        await run(request.body.data.wait);

        response.send({
            data: {
                status: true
                , message: 'message v2 '
            }
        })
    }
});

并从 angular/fire 插件触发

 const callable = this.afFnc.httpsCallable("helloWorldAllowCORS");
    
    console.log(new Date());
 
    // wait for 3 min
    this.data = await callable({ wait: 180 * 1000 });

    this.data.subscribe(
      res => {
        console.log(new Date());
        console.log(res);
      },
      err => {
        console.log(new Date());
        console.error(err);
      }

chrome 控制台在 1 分钟内显示超时错误

calling onTestCloudFunc()
2020-06-26T03:42:08.387Z
2020-06-26T03:43:18.401Z
Error: deadline-exceeded
    );

这几天我一直在纠结这个问题。官方的 firebase 文档并没有说明如何处理 CORS。一旦与 angular/fire 集成，httpCallable 函数就会失败。在我通过添加标题解决了 CORS 问题之后。话又说回来，新的 CORS 绕过逻辑打破了应该运行该进程 9 分钟的超时。

我也测试过，如果我增加超时，firebase 官方https://firebase.google.com/docs/functions 可以运行超过 1 分钟。但是代码只能通过手动复制粘贴到chrome浏览器中运行。

我注意到，当 firebase + angular/fire + cloud function + bypass CORS 时，定义的 Timeout 540s 将失败。谁有完全集成的代码参考？

百万升值~~T_T...

更新： 我创建了一个新的 onCall 函数 角度

console.log('Start Time: ', new Date());
// wait for 3 min
    const callable = this.afFnc.httpsCallable("onCWaitASec");
    this.data = await callable({ wait: 3 * 60 * 1000 });
this.data.subscribe(
  res => {
    console.log(new Date());
    console.log(res);
  },
  err => {
    console.log(new Date());
    console.error(err);
  }
);

Firebase Cloud Func，onCall 方法：

export const onCWaitASec = functions.runWith(runtimeOpts).https.onCall(async (data, context) => {
    
        let run = async (ms: any) => {
            await new Promise(resolve => setTimeout(resolve, ms));
        }
        await run(data.wait);

 return {
     status: 'success',
     message: `this is onCWaitASec() return msg waited ${data.wait} `
 }
})

Firebase 控制台还将超时显示为 540 秒。而chrome控制台的两个时间戳可以证明它在1分钟内超时

自 7 月 1 日起更新 谢天谢地，我从 Firebase 支持团队的 Mau 那里得到了帮助，他设法缩小了问题的范围是 AngularFire 包而不是 Firebase SDK 本身。这里是最新的工作代码（使用官方 Firebase JS SDK）

app.module.ts

import * as firebase from "firebase/app"; // official JS SDK
import { environment } from "../environments/environment";
if (!firebase.apps.length) {
   firebase.initializeApp(environment.firebaseConfig);
}

app.component.ts

import * as firebase from "firebase/app";
import "firebase/functions";
...
  async callCloudFnOfficial() {
    console.log("callCloudFnOfficial() Start Trigger At: ", new Date());
var callable = firebase.functions().httpsCallable("onCWaitASec", {timeout: 540000});
    callable({ wait: 500 * 1000 })
      .then(function(res) {
        console.log("success at ", new Date());
        console.log(res);
      })
      .catch(function(error) {
        console.log("Error at ", new Date());
        console.error(error);
      });
  }

Chrome 控制台日志

因为它终于能够执行 500 秒并成功返回。与角度/火力相比，总是在 1 分钟内返回

import { AngularFireFunctions } from "@angular/fire/functions";
...
  async callCloudFn() {
    console.log("Start Trigger At: ", new Date());
    const callable = this.fns.httpsCallable("onCWaitASec");
    // delay return for X seconds
    let cloudFncResp: Observable<any> = await callable({ wait: 500 * 1000 });
    cloudFncResp.subscribe(
      res => {
        console.log("success at ", new Date());
        console.log(res);
      },
      error => {
        console.log("Error at ", new Date());
        console.error(error);
      }
    );
  }

还会报告 AngularFire 中的错误，因为它不允许我们在客户端应用程序中设置超时。这是reported in firebase GitHub before。这里是我提到的the resolution。

Answer 1

您已经使用 onRequest 声明了一个 HTTP 函数：

export const helloWorldAllowCORS = functions.runWith(runtimeOpts).https
    .onRequest(async (request, response) => {

但您试图将其称为“可调用”函数，这是一种不同类型的函数：

const callable = this.afFnc.httpsCallable("helloWorldAllowCORS");

如果一定要通过仔细阅读链接文档来注意HTTP function 和callable function 之间的区别。如果要使用 HTTP 函数，则不应使用用于可调用函数的客户端库来调用它。如果要使用可调用函数，则应使用 onCall，如文档中所示。
