Firebase函数模拟器useFunctionsEmulator()方法不起作用 [英] firebase functions emulator useFunctionsEmulator() method not working

问题描述

我目前正在努力在本地测试我的云功能. 我发现了几种方法，但是使用Firebase模拟器和useFunctionsEmulator()方法似乎很棒.在 https://firebase.google.com/docs/functions/local-emulator，但他们并未提及该方法，但我在此网址

I am currently working on the way to test my cloud functions locally. I found several ways but using firebase emulator and useFunctionsEmulator() method seemed great. At https://firebase.google.com/docs/functions/local-emulator, they didn't say about the method, but I found it on this url How to test `functions.https.onCall` firebase cloud functions locally?.

但是，当我运行firebase模拟器时:start和console.log(firebase.functions().useFunctionsEmulator(' http://localhost :5001 ')，它只是显示为未定义.

However, when I run firebase emulator:start and console.log(firebase.functions().useFunctionsEmulator('http://localhost:5001'), it just showed undefined.

我尝试了几个关于原点的输入，但是没有改变.互联网上关于此的信息很少，我认为这是因为它是Alpha，所以请对此提供帮助.

I tried several inputs on the origin but nothing changed. There's so little information on the internet about this, I think that's because this is alpha, so Please help me on this.

推荐答案

在客户端中初始化Firebase应用之后，我通过调用useFunctionsEmulator()方法使模拟器工作并处理本地请求.事先调用它会导致错误.

I got the emulators working and handling local requests by calling the useFunctionsEmulator() method just after initializing the firebase app in the client. Calling it prior caused errors.

firebase.initializeApp(config);
firebase.functions().useFunctionsEmulator("http://localhost:5001");
