Facebook SDK FB.API 发布截图和用户消息

Question

我正在尝试发布屏幕截图并将其上传到用户的 Facebook 帐户。我正在使用 unity (c#) 并使用 facebook SDK，它与我从他们的文档中获得的示例代码一起工作正常。

我什至设法“预先填写”了一条消息并将其与屏幕截图一起发布。但是预填消息是违反Facebook Platform Policyexanples的，所以我正在寻找一种方法来使用相同的方法，让用户在不违反Facebook平台政策的情况下填写消息。

这是我使用的工作代码：

     private IEnumerator TakeScreenshot()
     {
         yield return new WaitForEndOfFrame();

         var width = Screen.width;
         var height = Screen.height;
         var tex = new Texture2D(width, height, TextureFormat.RGB24, false);
         // Read screen contents into the texture
         tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
         tex.Apply();
         byte[] screenshot = tex.EncodeToPNG();

         var wwwForm = new WWWForm();
         wwwForm.AddBinaryData("image", screenshot, "InteractiveConsole.png");
         wwwForm.AddField("message","some message"); // violating Facebook Platform Policy
         FB.API("me/photos", Facebook.HttpMethod.POST, Callback, wwwForm);
     }

Answer 1

这就是InputField 和Button 组件发挥作用的地方。使用InputField 获取用户消息并在单击按钮时发送。您可以在截屏前隐藏InputField 和发送Button。

public InputField userInput;
public Button postButton;


public void OnEnable()
{
    postButton.onClick.AddListener(postToFB);
}

void postToFB()
{
    Debug.Log("Posting To FB");
    StartCoroutine(TakeScreenshot(userInput.text));
}

private IEnumerator TakeScreenshot(string textToPost)
{
    //Hide User Input
    userInput.gameObject.SetActive(false);

    //Hide Send Button
    postButton.gameObject.SetActive(false);

    yield return new WaitForEndOfFrame();

    var width = Screen.width;
    var height = Screen.height;
    var tex = new Texture2D(width, height, TextureFormat.RGB24, false);
    // Read screen contents into the texture
    tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
    tex.Apply();
    byte[] screenshot = tex.EncodeToPNG();

    var wwwForm = new WWWForm();
    wwwForm.AddBinaryData("image", screenshot, "InteractiveConsole.png");
    wwwForm.AddField("message", textToPost);
    FB.API("me/photos", Facebook.HttpMethod.POST, Callback, wwwForm);
}

public void OnDisable()
{
    postButton.onClick.RemoveAllListeners();
}
