node.js - 使用 jest 和模拟器调用登录的 Firebase Auth 测试抛出错误：禁止标头 X-Client-Version

问题描述

我尝试使用 firebase js sdk localy 登录一个虚拟用户。我正在运行默认的 firebase 模拟器。调用该函数后，我得到以下异常：

    Error: Headers X-Client-Version forbidden
        at dispatchError (C:\Users\user\Documents\Projekte\Backend\functions\node_modules\jsdom\lib\jsdom\living\xhr\xhr-utils.js:62:19)

      at Request.onRequestResponse (node_modules/request/request.js:1059:10)

  console.log
    t {
      code: 'auth/network-request-failed',
      message: 'A network error (such as timeout, interrupted connection or unreachable host) has occurred.',
      a: null
    }

      at Object.<anonymous> (test/test.ts:275:12)

如果我尝试连接到我的在线项目，它工作正常，但我想用模拟器本地执行我的测试。

示例代码：


const app = firebase.initializeApp(firebaseConfig);

app.auth().useEmulator("http://localhost:9099");
app.firestore().settings({
    host: "localhost:8080",
    ssl: false,
});

test('Example test case', async () => {
        try {
            const cred: UserCredential = await app.auth().signInWithEmailAndPassword("foo@bar.de", "bla2377");
            expect(cred).toBeTruthy();
            expect(cred.user).toBeTruthy();
        } catch (e) {
            console.log(e);
            expect(true).toBeFalsy();
        }
    });

环境信息：

解决方案

jsdom 不支持 firebase 使用的通配符 access-control-allow-headers。这个答案修复了异常。
