Facebook 遊戲開發更新文件 API參考v6.2

更新日誌 1.連線玩家得分條目 引入新Leaderboard.getConnectedPlayerEntriesAsync()API，從排行榜獲取當前玩家連線玩家的得分條目。

FBInstant Instant Games SDK的頂級名稱空間。

播放機 包含與當前播放器相關的功能和屬性。

getID（） 播放器的唯一識別符號。Facebook使用者的玩家ID將保持不變，並且範圍限定為特定遊戲。這意味著不同的遊戲將為同一使用者提供不同的玩家ID。在FBInstant.initializeAsync（）解決之前，不應呼叫此函式。 例子 //應該在FBInstant.initializeAsync（）//結算後呼叫此函式。var playerID = FBInstant 。球員。getID （）; 返回字串？播放器的唯一識別符號。

getSignedPlayerInfoAsync（） 獲取播放器的唯一識別符號以及簽名，該簽名驗證識別符號確實來自Facebook而不會被篡改。在FBInstant.initializeAsync（）解決之前，不應呼叫此函式。 引數 requestPayload 字串？開發人員指定的有效負載，包含在已簽名的響應中。 例子 //應該在FBInstant.initializeAsync（）//結算後呼叫此函式。FBInstant 。球員。getSignedPlayerInfoAsync （'my_metadata' ）。然後（函式（結果）{ // ID和簽名的驗證應該發生在伺服器端。SendToMyServer （ 結果。getPlayerID （），//相同的值FBInstant.player.getID（） 結果。getSignature （），“GAIN_COINS ' ，100 ）; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise < SignedPlayerInfo >使用#signedplayerinfo物件解析的 promise。

canSubscribeBotAsync（） 返回一個承諾，該承諾通過玩家是否可以訂閱遊戲機器人來解決。 例子 //應該在FBInstant.player.subscribeBotAsync（）FBInstant 之前呼叫此函式。球員。canSubscribeBotAsync （）。然後（ can_subscribe => 控制檯。日誌（can_subscribe ））; //'真' 返回Promise < boolean >玩家是否可以訂閱遊戲機器人。開發人員只能在檢查canSubscribeBotAsync（）後呼叫subscribeBotAsync（），並且播放器只能在特定遊戲中看到一次此機器人訂閱對話方塊。

subscribeBotAsync（） 請求玩家訂閱與遊戲相關聯的機器人。如果訂閱失敗，API將拒絕 - 否則，玩家將訂閱遊戲機器人。 例子 FBInstant 。球員。subscribeBotAsync （）。然後（//玩家訂閱機器人）。catch （function （e ）{ //處理訂閱失敗}）;

丟擲INVALID_PARAM 丟擲PENDING_REQUEST 引發CLIENT_REQUIRES_UPDATE 返回Promise一個承諾，如果玩家成功訂閱遊戲機器人，則解析，或者如果請求失敗或玩家選擇不訂閱則拒絕。

getName（） 播放器的本地化顯示名稱。在FBInstant.startGameAsync（）解析之前，不應呼叫此函式。 例子 //應該在FBInstant.startGameAsync（）//結算後呼叫此函式。var playerName = FBInstant 。球員。getName （）; 返回字串？播放器的本地化顯示名稱。

getPhoto（） 玩家公開個人資料照片的網址。照片將始終為正方形，尺寸至少為200x200。在遊戲中渲染時，不應假設精確尺寸不變。建議在渲染之前始終將影象縮放到所需的大小。在FBInstant.startGameAsync（）結算之前，該值始終為null。 警告：由於CORS，在遊戲畫布中使用這些照片會導致它被汙染，這將阻止提取畫布資料。要防止這種情況，請將您使用的影象的跨原點屬性設定為“匿名”。 例子 var playerImage = new Image （）; playerImage 。crossOrigin = 'anonymous' ; //應該在FBInstant.startGameAsync（）//結算後呼叫此函式。 playerImage 。src = FBInstant 。球員。getPhoto （）;
返回字串？網址為玩家的公開個人資料照片。

getDataAsync（） 從當前播放器的指定雲端儲存中檢索資料。 引數 keys Array < string >用於檢索資料的唯一鍵陣列。 例子 FBInstant 。球員 。getDataAsync （[ 'achievement' ，'currentLife' ]）。然後（功能（資料）{ 控制檯。日誌（'資料載入' ）; VAR 成就= 資料[ '成就' ]; VAR currentLife = 資料[ 'currentLife' ]; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise < Object >一個promise，它使用一個物件解析，該物件包含輸入陣列中指定的每個鍵的當前鍵值對（如果存在）。

setDataAsync（） 將資料設定為當前播放器的指定雲端儲存。該遊戲可以為每個獨特的玩家儲存多達1MB的資料。 引數 data Object包含應保留到雲端儲存的一組鍵值對的物件。該物件必須只包含可序列化的值 - 任何不可序列化的值都將導致整個修改被拒絕。 例子 FBInstant 。球員 。setDataAsync （{ achievement ：[ 'medal1' ，'medal2' ，'medal3' ]， currentLife ：300 ，}）。然後（函式（）{ 控制檯。登入（'資料被設定' ）; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲PENDING_REQUEST 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise在設定輸入值時解析的promise。注意：承諾解析並不一定意味著輸入已被持久化。相反，它意味著資料有效並已安排儲存。它還保證所有已設定的值現在都可以在player.getDataAsync中使用。

flushDataAsync（） 立即將對播放器資料的任何更改重新整理到指定的雲端儲存。此功能很昂貴，主要應用於需要立即持久並且遊戲已知的永續性的關鍵更改。非關鍵性更改應依賴於平臺將其保留在後臺。注意：當此函式的結果處於掛起狀態時，將拒絕對player.setDataAsync的呼叫。 例子 FBInstant 。球員 。setDataAsync （{ achievement ：[ 'medal1' ，'medal2' ，'medal3' ]， currentLife ：300 ，}）。然後（FBInstant 。球員。flushDataAsync ）。然後（函式（）{ 控制檯。登入（'資料儲存到FB！' ）; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲PENDING_REQUEST 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise在成功持久儲存更改時解析的promise，如果儲存失敗則拒絕。

getStatsAsync（） 從當前播放器的指定雲端儲存中檢索統計資訊。 引數 keys 陣列 < string >？用於檢索統計資訊的可選陣列唯一鍵。如果在沒有它的情況下呼叫該函式，它將獲取所有統計資訊。 例子 FBInstant 。球員 。getStatsAsync （[ 'level' ，'zombiesSlain' ]）。然後（函式（統計）{ 控制檯。日誌（'統計被載入' ）; 無功電平= 資料[ '等級' ]; VAR zombiesSlain = 資料[ 'zombiesSlain' ]; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise < Object >一個promise，它使用一個物件解析，該物件包含輸入陣列中指定的每個鍵的當前鍵值對（如果存在）。

setStatsAsync（） 將統計資訊設定為當前播放器的指定雲端儲存。 引數 stats Object包含一組鍵值對的物件，這些鍵值對應作為統計資訊儲存到雲端儲存中，可以通過多種方式顯示或使用，以有益於玩家參與。物件必須只包含數值 - 任何非數值都將導致整個修改被拒絕。 例子 FBInstant 。球員 。setStatsAsync （{ level ：5 ， zombiesSlain ：27 ，}）。然後（函式（）{ 控制檯。登入（'資料被設定' ）; }）;

丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲PENDING_REQUEST 丟擲CLIENT_UNSUPPORTED_OPERATION Returns Promise A promise that resolves when the input values are set. NOTE: The promise resolving does not necessarily mean that the input has already been persisted. Rather, it means that the data was validated and has been scheduled to be saved. It also guarantees that all values that were set are now available in player.getStatsAsync.

incrementStatsAsync( ) Increment stats saved in the designated cloud storage of the current player. Parameters increments Object An object containing a set of key-value pairs indicating how much to increment each stat in cloud storage. The object must contain only numerical values - any non-numerical values will cause the entire modification to be rejected. Examples FBInstant.player .incrementStatsAsync({ level: 1, zombiesSlain: 17, rank: -1, }) .then(function(stats)) { console.log('increments have been made! New values'); var level = data['level']; var zombiesSlain = data['zombiesSlain']; }); 丟擲INVALID_PARAM 引發NETWORK_FAILURE 丟擲PENDING_REQUEST 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise < Object >一個promise，它使用一個物件解析，該物件包含輸入字典中指定的每個鍵的更新鍵值對。注意：承諾解決並不一定意味著更改已經保留。相反，它意味著增量有效並已安排執行。它還保證所有遞增的值現在都可以在player.getStatsAsync中使用。

getConnectedPlayersAsync（） 獲取一組ConnectedPlayer物件，其中包含有關連線到當前玩家的活動玩家（在過去90天內玩過該遊戲的人）的資訊。 例子 var connectedPlayers = FBInstant 。球員。getConnectedPlayersAsync （）。然後（功能（播放器）{ 控制檯。日誌（球員。地圖（功能（播放器）{ 返回{ ID ：玩家。的getID （）， 名稱：玩家。的getName （）} }））; }）;

// [{id：'123456789'，名稱：'Paul Atreides'}，{id：'987654321'，名稱：'Duncan Idaho'}] 引發NETWORK_FAILURE 丟擲CLIENT_UNSUPPORTED_OPERATION 返回Promise < Array < ConnectedPlayer >>使用已連線的播放器物件列表解析的promise。注意：在FBInstant.startGameAsync（）解析之前，不應呼叫此函式。

上下文 包含與當前遊戲上下文相關的功能和屬性。

getID（） 當前遊戲上下文的唯一識別符號。這表示正在播放遊戲的特定上下文（例如，特定的信使對話或Facebook帖子）。如果在獨奏上下文中播放遊戲，則識別符號將為null。在FBInstant.startGameAsync解決之前，不應呼叫此函式。 例子 //應該在FBInstant.startGameAsync（）//結算後呼叫此函式。var contextID = FBInstant 。背景。getID （）; 返回字串？當前遊戲上下文的唯一識別符號。

getType（） The type of the current game context. POST - A facebook post. THREAD - A messenger thread. GROUP - A facebook group. SOLO - Default context, where the player is the only participant. This function should not be called until FBInstant.startGameAsync has resolved. Examples // This function should be called after FBInstant.startGameAsync()// resolves.var contextType = FBInstant.context.getType(); Returns ("POST" | "THREAD" | "GROUP" | "SOLO") Type of the current game context.

isSizeBetween( ) This function determines whether the number of participants in the current game context is between a given minimum and maximum, inclusive. If one of the bounds is null only the other bound will be checked against. It will always return the original result for the first call made in a context in a given game play session. Subsequent calls, regardless of arguments, will return the answer to the original query until a context change occurs and the query result is reset. This function should not be called until FBInstant.startGameAsync has resolved. Parameters minSize number? The minimum bound of the context size query. minSize number? The maximum bound of the context size query. maxSize number? Examples console.log(FBInstant.context.isSizeBetween(3, 5)); (Context size = 4)// {answer: true, minSize: 3, maxSize: 5} console.log(FBInstant.context.isSizeBetween(5, 7)); (Context size = 4)// {answer: false, minSize: 5, maxSize: 7} console.log(FBInstant.context.isSizeBetween(2, 10)); (Context size = 3)// {answer: true, minSize: 2, maxSize: 10} console.log(FBInstant.context.isSizeBetween(4, 8)); (Still in same context)// {answer: true, minSize: 2, maxSize: 10} console.log(FBInstant.context.isSizeBetween(3, null)); (Context size = 4)// {answer: true, minSize: 3, maxSize: null} console.log(FBInstant.context.isSizeBetween(null, 3)); (Context size = 4)// {answer: false, minSize: null, maxSize: 3} 控制檯。日誌（FBInstant 。上下文。isSizeBetween （“測試” ，5 ））; （上下文大小= 4 ）// null
控制檯。日誌（FBInstant 。上下文。isSizeBetween （0 ，100 ））; （Context size = null ）// null

Changelog 1.Connected Player Score Entries Introduces the new Leaderboard.getConnectedPlayerEntriesAsync() API, which fetches the score entries of the current player's connected players from the leaderboard.

FBInstant Top level namespace for the Instant Games SDK.

player Contains functions and properties related to the current player.

getID( ) A unique identifier for the player. A Facebook user's player ID will remain constant, and is scoped to a specific game. This means that different games will have different player IDs for the same user. This function should not be called until FBInstant.initializeAsync() has resolved. Examples // This function should be called after FBInstant.initializeAsync()// resolves.var playerID = FBInstant.player.getID(); Returns string? A unique identifier for the player.

getSignedPlayerInfoAsync( ) Fetch the player's unique identifier along with a signature that verifies that the identifier indeed comes from Facebook without being tampered with. This function should not be called until FBInstant.initializeAsync() has resolved. Parameters requestPayload string? A developer-specified payload to include in the signed response. Examples // This function should be called after FBInstant.initializeAsync()// resolves.FBInstant.player.getSignedPlayerInfoAsync('my_metadata') .then(function (result) { // The verification of the ID and signature should happen on server side. SendToMyServer( result.getPlayerID(), // same value as FBInstant.player.getID() result.getSignature(), 'GAIN_COINS', 100); }); Throws INVALID_PARAM Throws NETWORK_FAILURE Throws CLIENT_UNSUPPORTED_OPERATION Returns Promise A promise that resolves with a #signedplayerinfo object.

canSubscribeBotAsync( ) Returns a promise that resolves with whether the player can subscribe to the game bot or not. Examples // This function should be called before FBInstant.player.subscribeBotAsync()FBInstant.player.canSubscribeBotAsync().then( can_subscribe => console.log(can_subscribe));// 'true' Returns Promise Whether a player can subscribe to the game bot or not. Developer can only call subscribeBotAsync() after checking canSubscribeBotAsync(), and the player will only be able to see this bot subscription dialog once for a specific game.

subscribeBotAsync( ) Request that the player subscribe the bot associated to the game. The API will reject if the subscription fails - else, the player will subscribe the game bot. Examples FBInstant.player.subscribeBotAsync().then( // Player is subscribed to the bot).catch(function (e) { // Handle subscription failure}); Throws INVALID_PARAM Throws PENDING_REQUEST Throws CLIENT_REQUIRES_UPDATE Returns Promise A promise that resolves if player successfully subscribed to the game bot, or rejects if request failed or player chose to not subscribe.

getName( ) The player's localized display name. This function should not be called until FBInstant.startGameAsync() has resolved. Examples // This function should be called after FBInstant.startGameAsync()// resolves.var playerName = FBInstant.player.getName(); Returns string? The player's localized display name.

getPhoto( ) A url to the player's public profile photo. The photo will always be a square, and with dimensions of at least 200x200. When rendering it in the game, the exact dimensions should never be assumed to be constant. It's recommended to always scale the image to a desired size before rendering. The value will always be null until FBInstant.startGameAsync() resolves. WARNING: Due to CORS, using these photos in the game canvas can cause it to be tainted, which will prevent the canvas data from being extracted. To prevent this, set the cross-origin attribute of the images you use to 'anonymous'. Examples var playerImage = new Image(); playerImage.crossOrigin = 'anonymous';// This function should be called after FBInstant.startGameAsync()// resolves. playerImage.src = FBInstant.player.getPhoto(); Returns string? Url to the player's public profile photo.

getDataAsync( ) Retrieve data from the designated cloud storage of the current player. Parameters keys Array An array of unique keys to retrieve data for. Examples FBInstant.player .getDataAsync(['achievements', 'currentLife']) .then(function(data) { console.log('data is loaded'); var achievements = data['achievements']; var currentLife = data['currentLife']; }); Throws INVALID_PARAM Throws NETWORK_FAILURE Throws CLIENT_UNSUPPORTED_OPERATION Returns Promise A promise that resolves with an object which contains the current key-value pairs for each key specified in the input array, if they exist.

setDataAsync( ) Set data to be saved to the designated cloud storage of the current player. The game can store up to 1MB of data for each unique player. Parameters data Object An object containing a set of key-value pairs that should be persisted to cloud storage. The object must contain only serializable values - any non-serializable values will cause the entire modification to be rejected. Examples FBInstant.player .setDataAsync({ achievements: ['medal1', 'medal2', 'medal3'], currentLife: 300, }) .then(function() { console.log('data is set'); }); Throws INVALID_PARAM Throws NETWORK_FAILURE Throws PENDING_REQUEST Throws CLIENT_UNSUPPORTED_OPERATION Returns Promise A promise that resolves when the input values are set. NOTE: The promise resolving does not necessarily mean that the input has already been persisted. Rather, it means that the data was valid and has been scheduled to be saved. It also guarantees that all values that were set are now available in player.getDataAsync.

flushDataAsync( ) Immediately flushes any changes to the player data to the designated cloud storage. This function is expensive, and should primarily be used for critical changes where persistence needs to be immediate and known by the game. Non-critical changes should rely on the platform to persist them in the background. NOTE: Calls to player.setDataAsync will be rejected while this function's result is pending. Examples FBInstant.player .setDataAsync({ achievements: ['medal1', 'medal2', 'medal3'], currentLife: 300, }) .then(FBInstant.player.flushDataAsync) .then(function() { console.log('Data persisted to FB!'); }); Throws INVALID_PARAM Throws NETWORK_FAILURE Throws PENDING_REQUEST Throws CLIENT_UNSUPPORTED_OPERATION Returns Promise A promise that resolves when changes have been persisted successfully, and rejects if the save fails.

getStatsAsync( ) Retrieve stats from the designated cloud storage of the current player. Parameters keys Array? An optional array of unique keys to retrieve stats for. If the function is called without it, it will fetch all stats.

ErrorCode Error codes that may be returned by the Instant Games API Properties ADS_FREQUENT_LOAD string Ads are being loaded too frequently. ADS_NO_FILL string We were not able to serve ads to the current user. This can happen if the user has opted out of interest-based ads on their device, or if we do not have ad inventory to show for that user. ADS_NOT_LOADED string Attempted to show an ad that has not been loaded successfully. ADS_TOO_MANY_INSTANCES string There are too many concurrent ad instances. Load and show existing ad instances before creating new ones. ANALYTICS_POST_EXCEPTION string The analytics API experienced a problem while attempting to post an event. CLIENT_REQUIRES_UPDATE string [Deprecated] - The client requires an update to access the feature that returned this result. If this result is returned on web, it means the feature is not supported by the web client yet. Deprecated in favor of CLIENT_UNSUPPORTED_OPERATION in v5.0 and above CLIENT_UNSUPPORTED_OPERATION string The client does not support the current operation. This may be due to lack of support on the client version or platform, or because the operation is not allowed for the game or player. INVALID_OPERATION string The requested operation is invalid or the current game state. This may include requests that violate limitations, such as exceeding storage thresholds, or are not available in a certain state, such as making a context-specific request in a solo context. INVALID_PARAM string The parameter(s) passed to the API are invalid. Could indicate an incorrect type, invalid number of arguments, or a semantic issue (for example, passing an unserializable object to a serializing function). LEADERBOARD_NOT_FOUND string No leaderboard with the requested name was found. Either the leaderboard does not exist yet, or the name did not match any registered leaderboard configuration for the game. LEADERBOARD_WRONG_CONTEXT string Attempted to write to a leaderboard that's associated with a context other than the one the game is currently being played in. NETWORK_FAILURE string The client experienced an issue with a network request. This is likely due to a transient issue, such as the player's internet connection dropping. PAYMENTS_NOT_INITIALIZED string The client has not completed setting up payments or is not accepting payments API calls. PENDING_REQUEST string Represents a rejection due an existing request that conflicts with this one. For example, we will reject any calls that would surface a Facebook UI when another request that depends on a Facebook UI is pending. RATE_LIMITED string Some APIs or operations are being called too often. This is likely due to the game calling a particular API an excessive amount of times in a very short period. Reducing the rate of requests should cause this error to go away. SAME_CONTEXT string The game attempted to perform a context switch into the current context. UNKNOWN string An unknown or unspecified issue occurred. This is the default error code returned when the client does not specify a code. USER_INPUT string The user made a choice that resulted in a rejection. For example, if the game calls up the Context Switch dialog and the player closes it, this error code will be included in the promise rejection. Examples FBInstant.startGameAsync().catch(function(e) { console.log(e);});// {code: 'CLIENT_UNSUPPORTED_OPERATION', message: '...'}
