準備

Gcp/Firebase/CloudFunctions [ショートカット]

import

FirebaseFunctions.unitypackage をunityのAssets/ImportPackage/CustomPackageからImportする

初期化

using Firebase.Functions;
FirebaseFunctions functions = FirebaseFunctions.DefaultInstance;

東京リージョンの場合こちらを記述

using Firebase.Functions;
FirebaseFunctions functions = FirebaseFunctions.GetInstance("asia-northeast1");

サンプル

ScoreEntry score = new ScoreEntry();
AddEntry(score);
using System.Threading.Tasks;
   class ScoreEntry {
       public string Name = "taro";
       public int Age = 100;
   }
   async Task<object> AddEntryAsync(ScoreEntry score)
   {
       object data = new Dictionary<object, object>
       {
           { "name", score.Name },
           { "age", score.Age },
       };
       return await functions.GetHttpsCallable("addEntry").CallAsync(data)
           .ContinueWith(task =>
           {
               return task.Result.Data;
           });
   }
   void AddEntry(ScoreEntry score)
   {
       AddEntryAsync(score).ContinueWith(task =>
       {
           if (task.IsFaulted)
           {
               // onError
           }
           else
           {
               // onComplete
               Debug.Log("task.Result=" + task.Result); // OK
           }
       }, TaskScheduler.FromCurrentSynchronizationContext());
   }

firebaseのサーバー側変更

functions.https.onCall を使ってシリアル&認証トークンで接続するようにする

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
// 追加
exports.addEntry = functions
  .region('asia-northeast1')
  .https.onCall((data, context) =>
{
  const entry = {
    name : data.name,
    point : data.point
  };
  return admin.firestore().collection('entries')
    .add(entry)
    .then((snapshot) =>
  {
    return 'OK';
  });
});
// 更新
exports.replaceEntry = functions
  .region('asia-northeast1')
  .https.onCall((data, context) =>
{
  const entry = {
    name : data.name,
    point : data.point
  };
  return admin.firestore().collection('entries')
    .doc("ID1").set(entry)
    .then((snapshot) =>
  {
    return 'OK';
  });
});
//  トップcount件のEntryを取得
exports.getTopEntries = functions
  .region('asia-northeast1')
  .https.onCall((data, context) =>
{
  const count = data.count;
  return admin.firestore().collection('entries')
    .orderBy('point', 'desc')
    .limit(count)
    .get()
    .then((snapshot) =>
  {
    var obj = {
        status: 'ok',
        notice: '',
        users: snapshot.docs.map(x => x.data()),
    }
    var json=JSON.stringify(obj);
    return json;
  });
});
