我遇到Callable Functions的问题。这是我的Firebase函数：
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const request = require('request-promise');
admin.initializeApp(functions.config().firebase);
exports.phoneAuthRequest = functions.https.onCall((data, context) => {
// Message text passed from the client.
const text = data.text;
// Authentication / user information is automatically added to the request.
const uid = context.auth.uid;
const phone = context.auth.token.phone_number;
const url = "https://api.authy.com/protected/json/phones/verification/start?api_key=<key here>&via=sms&country_code=1&phone_number=" + phone;
const httpReq = {
uri: url,
method: 'POST',
json: true,
resolveWithFullResponse: true
};
return new Promise((resolve, reject) => {
request(httpReq).then((response) => {
// Twillio request returned with success
console.log("response: " + JSON.stringify(response));
return resolve(response);
}).catch(function(error) {
console.log("error: " + JSON.stringify(error));
return reject(error);
});
});
});
这是我的客户示例：
<html>
<head>
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-app.js"></script>
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-auth.js"></script>
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-database.js"></script>
<script src="https://www.gstatic.com/firebasejs/5.4.2/firebase-functions.js"></script>
<script>
var config = { <firebase configuration in here> };
firebase.initializeApp(config);
function myTest() {
var display = document.getElementById('display');
display.innerHTML = "Started";
var auth = firebase.auth();
auth.signInWithEmailAndPassword(<username>,<password>).then(function(authResult) {
display.innerHTML = "Signed in";
var phoneAuthRequest = firebase.functions().httpsCallable('phoneAuthRequest');
phoneAuthRequest({'text': 'Test'}).then(function(result) {
display.innerHTML = JSON.stringify(result);
}).catch(function(error) {
display.innerHTML = JSON.stringify(error);
});
}).catch(function(error) {
display.innerHTML = "Login failure. Your email or password could not be validated. " + JSON.stringify(error);
});
}
</script>
</head>
<body>
<input type="submit" value="Test It" data-wait="Loading..." id="loginBtn" class="login-window-login-btn w-button" onclick="myTest();">
<div id="display"></div>
</body>
</html>
对此代码组合进行的测试显示，Firebase函数'phoneAuthRequest'被调用，这继而向Twillio发出了请求，并且Twillio的响应被正确返回，但控制台日志显示了此错误：
Unhandled error RangeError: Maximum call stack size exceeded

当然，返回给客户端的响应是：
{"code":"internal"}
当我阅读类似的帖子时，建议是序列化诺言，我不确定我是否完全理解该怎么做，或者包装异步调用（在这种情况下为请求）一个新的承诺中，这正是我在这里所做的，但仍然没有用。
如果您要回答这个问题，可以通过显示代码示例来具体说明建议的解决方案吗？
预先感谢...

尝试消除客户端并通过curl调用Firebase函数。

好吧，我通过将我的头撞到墙上来解决了这个问题。这是代码：
exports.phoneAuthRequest = functions.https.onCall((data, context) => {
// Example of using context to obtain the user information about the calling user
const uid = context.auth.uid;
// Example of obtaining a paramter that was passed by the calling function
const phone = data.phone;
const e164 = "+1" + phone;
httpReq = ...
// Example of a return if you have not yet made a call to an asynchonous function.
return ({'status': 'success'});
// Here is an example of a nested set of asynchonous calls and how to return from them.
return admin.auth().updateUser(uid, {'phoneNumber': e164}).then(function(userRecord) {
// the Phone Number was updated
return request(httpReq).then((response) => {
var updates = {};
updates['/users/' + uid + "/centralVerified"] = false;
return database.ref().update(updates).then(function(rslt) {
return Promise.resolve({'status': 'success');
}).catch(function(error) {
return Promise.reject({'status': 'failed'});
});
}).catch(function(error) {
return Promise.reject({'status': 'failed'});
});
}).catch(function(error) {
return Promise.reject({'status': 'failed'});
});
});
以上注意，从可调用函数返回有两种不同的方法。如果没有进行异步调用，则可以简单地返回值，但是，如果调用了异步函数，则必须返回一个promise。如果要在调用例程中查找“拒绝”或“解决”，则假定返回值是“解决”。
我希望这对其他人有帮助...祝你好运！
