为什么FBInstant.chooseAsync方法不向朋友发送游戏请求？

Question

我正在尝试使用FBinstant.chooseAsync方法向我的facebook firend发送游戏请求。但没有请求发送给我的朋友，我在调用此方法后没有收到回调数据。

这是我的游戏代码 -

 FBInstant.initializeAsync() .then(function() { 


    console.log("FBInstant.initializeAsync complete"); 


    console.log("FBInstant.startGameAsync complete"); 
    FBInstant.startGameAsync().then(function() { 

        console.log("FBInstant.startGameAsync complete"); 
        console.log("FBInstant.startGameAsync context : " + FBInstant.context.getID()); 

        FBInstant.context.chooseAsync() .then(function (e) { 

            console.log("FBInstant.context.chooseAsync complete"); 
            console.log(e); 
        }); 
    }); 

});

Answer 1

首先，FBInstant.context.chooseAsync()打开一个上下文选择对话框（参见API Reference v6.2）。第二，为什么你两次使用FBInstant.startGameAsync（）？试试这段代码：

FBInstant.initializeAsync() .then(function() {

    // Start loading game assets here 
    console.log("FBInstant.initializeAsync complete"); 

    // Finished loading. Start the game 
    FBInstant.startGameAsync().then(function() { 

        console.log("FBInstant.startGameAsync complete"); 
        console.log("FBInstant.startGameAsync context : " + FBInstant.context.getID()); 

        FBInstant.context.chooseAsync() .then(function () { 
            console.log("FBInstant.context.chooseAsync complete");
        }); 

    }); 
});

看来你必须在chooseAsync的resolve函数中调用updateAsync，你可以尝试像flow这样的东西：

FBInstant.context.chooseAsync() .then(function () { 
    window.FBInstant.updateAsync(
    {
      action: "CUSTOM",
      cta: "Join The Fight",
      template: "join_fight",
      image: base64Picture, //this should be source data of your share picture in 
                            //base64! you can parse your picture to base64 use  
                            //'https://www.base64-image.de'
      text: "X just invaded Y's village!",
      data: {
        myReplayData: "..."
      },
      strategy: "IMMEDIATE",
      notification: "NO_PUSH"
    }).then(function() {
      window.FBInstant.quit();
    }).catch(function(err){
        console.error(err);
    });

});
