「Unity/Firebase/CloudFunctions」の版間の差分

2019年8月7日 (水) 01:13時点における版

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';
  });
});

[Serializable]
class ResData
{
    public string status = "ok";
    public string notice = "";
    public List<ResUser> users;
}
[Serializable]
class ResUser
{
    public int point = 0;
    public string name = "";
}
void GetTopEntries()
{
    GetTopEntriesAsync().ContinueWith(task =>
    {
        if (task.IsFaulted)
        {
            // onError
        }
        else
        {
            // onComplete
            string json = task.Result.ToString();
            Debug.Log("json=" + json);
            ResData resData = JsonUtility.FromJson<ResData>(json);
            Debug.Log("status=" + resData.status);
            Debug.Log("notice=" + resData.notice);
            foreach (ResUser user in resData.users)
            {
                Debug.Log("user.name=" + user.name);
                Debug.Log("user.point=" + user.point);
            }
        }
    }, TaskScheduler.FromCurrentSynchronizationContext());
}
