异常"firebase.functions()接受...无自变量..."为Cloud Function指定区域时 [英] Exception "firebase.functions() takes ... no argument ..." when specifying a region for a Cloud Function
问题描述
我正在跟踪Firebase 文档，以便通过网络进行呼叫页面上的可调用函数"位于与us-central1不同的区域中.
I am following the Firebase documentation in order to call, from a web page, a Callable Function located in a different region than us-central1.
更准确地说，在网页中，我执行了var functions = firebase.functions('europe-west1');，但是收到以下错误，但调用没有结果:
More precisely, in the web page, I do var functions = firebase.functions('europe-west1'); but I get the following error and no result from the call:
uncaught exception: functions: Firebase: firebase.functions() takes either no argument or a Firebase App instance. (app/invalid-app-argument).
这是MCV代码:
云功能
const functions = require('firebase-functions');
exports.getName = functions
.region('europe-west1')
.https.onCall((data, context) => {
return { name: 'MyName' };
});

// Initialize Firebase
var config = {

authDomain: "xxxxxxxxxx",
databaseURL: "xxxxxxxxxx",
projectId: "xxxxxxxxxx",
storageBucket: "xxxxxxxxxx",
messagingSenderId: "xxxxxxxxxx",
};
firebase.initializeApp(config);
var functions = firebase.functions('europe-west1');
var getName = functions.httpsCallable('getName');
getName().then(function (result) {
console.log((result.data));
}).catch(function (error) {
// Getting the Error details.
var code = error.code;
var message = error.message;
var details = error.details;
});
</script>
</body>
</html>
如果我在us-central1区域中运行相同的代码(不带参数调用firebase.functions())，它将正常工作.
If I run the same code in the us-central1 region (calling firebase.functions() without argument) it works correctly.
云功能(us-central1版本)
Cloud Function (us-central1 version)
const functions = require('firebase-functions');
exports.getName = functions
.https.onCall((data, context) => {
return { name: 'MyName' };
});
网页(us-central1版本)
Web Page (us-central1 version)
<!DOCTYPE html>
<html lang="en">
.....
<body>
<script>
// Initialize Firebase
var config = {
.....
};
firebase.initializeApp(config);
var functions = firebase.functions();
...
</script>
</body>
</html>
请注意，我已经将我的开发环境更新为最新版本的firebase-functions，firebase-admin和firebase-tools.
Note that I've updated my dev environment to the latest versions of firebase-functions, firebase-admin and firebase-tools.
推荐答案
通过反复试验，我发现您必须这样做:
By trial and error I found that you have to do it like this:
var config = {
apiKey: "xxxxxxxxxx",
authDomain: "xxxxxxxxxx",
databaseURL: "xxxxxxxxxx",
projectId: "xxxxxxxxxx",
storageBucket: "xxxxxxxxxx",
messagingSenderId: "xxxxxxxxxx",
};
var fireApp = firebase.initializeApp(config);
var functions = fireApp.functions('europe-west1');
