Question

我试图发布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，它可以正常使用我们从他们的Docs获得的示例代码。

我甚至设法＆＃34;预先填写＆＃34;一条消息并用截图发布。但是预先填写邮件是针对Facebook Platform Policy exanples的，因此我正在寻找一种方法来使用相同的方法，让用户在我不打破时填写邮件Facebook平台政策。

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);
     }

这是InputField和Button组件发挥作用的地方。获取InputField的用户消息，并在单击按钮时发送。您可以在截取屏幕截图之前隐藏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();
}

Facebook SDK FB.API发布用户消息的屏幕截图
