博览会项目中的Firebase Cloud功能

Question

所以我有一个云功能(这还没有在react native应用程序目录中):

const admin = require('firebase-admin');
const firebase_tools = require('firebase-tools');
const functions = require('firebase-functions');
admin.initializeApp();

exports.deleteUser = functions
.runWith({
timeoutSeconds: 540,
memory: '2GB'
})
.https.onCall((data, context) => {
const userId = context.auth.uid;
var promises = [];
// DELETE DATA
var paths = ['users/' + userId, 'messages/' + userId, 'chat/' + userId];
paths.forEach((path) => {
promises.push(
recursiveDelete(path).then(  () => {
return 'success';
}
).catch( (error) => {
console.log('Error deleting user data: ', error);
})
);
});
// DELETE FILES
const bucket = admin.storage().bucket();
var image_paths = ["avatar/" + userId, "avatar2/" + userId, "avatar3/" + userId];
image_paths.forEach((path) => {
promises.push(
bucket.file(path).delete().then(  () => {
return 'success';
}
).catch( (error) => {
console.log('Error deleting user data: ', error);
})
);
});
// DELETE USER
promises.push(
admin.auth().deleteUser(userId)
.then( () => {
console.log('Successfully deleted user');
return true;
})
.catch((error) => {
console.log('Error deleting user:', error);
})
);
return Promise.all(promises).then(() => {
return true;
}).catch(er => {
console.error('...', er);
});
});


function recursiveDelete(path, context) {
return firebase_tools.firestore
.delete(path, {
project: process.env.GCLOUD_PROJECT,
recursive: true,
yes: true,
token: functions.config().fb.token
})
.then(() => {
return {
path: path
}
}).catch( (error) => {
console.log('error: ', error);
return error;
});
}
// [END recursive_delete_function]

这是用于我的swift应用程序。我怎么能使用它为我的react native应用程序构建与Expo?

我已经安装了以下yarn add @react-native-firebase/functions

我有我的firebase.js文件设置在根目录:

import * as firebase from "firebase";
// Your web app's Firebase configuration
var firebaseConfig = {
apiKey: "test",
authDomain: "test",
databaseURL: "test",
projectId: "test",
storageBucket: "test",
messagingSenderId: "test",
appId: "test"
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);
export default firebase;

我有一个按钮:

<Text>Delete Account</Text>
<View>
<Button
title="Delete Account"
color="#F9578E"
accessibilityLabel="Delete Account"
/>
</View>

点击后将用户签出并运行上述云功能。

我不精通react-native和Expo，但从@react-native-firebase/functions文档来看，您似乎需要这样做:

import functions from '@react-native-firebase/functions';
function App() {

useEffect(() => {
functions()
.httpsCallable('deleteUser')()
.then(response => {
// ....
});
}, []);

// ...
}

你没有从你的应用程序传递任何数据到你的可调用的云函数，即你没有在你的云函数中使用data对象，这就是为什么你需要做functions().httpsCallable('deleteUser')()。如果需要传递一些数据，文档中给出了一个示例，传递一个对象:

functions().httpsCallable('listProducts')({
page: 1,
limit: 15,
})

(这完全符合Firebase JS SDK调用可调用云函数的方式，这就是为什么我回答了这个问题，即使缺乏react-native和Expo的知识…)
