改变Facebook Unity SDK中的CurrentAccessToken [英] Changing CurrentAccessToken in Facebook Unity SDK

问题描述

我正在使用iOS上运行的Unity Facebook SDK发布到Facebook页面。据我所知，为了做到这一点，我需要使用 manage_pages 和 publish_pages 的页面访问令牌。我知道我可以从 / me / accounts？fields = access_token 得到它，但是如何告诉 AccessToken.CurrentAccessToken 使用我的页面访问令牌？

I'm trying to post to a Facebook page AS the page using the Unity Facebook SDK running on iOS. As I understand, to do that, I need the pages access token with manage_pages and publish_pages. I know that I can get it from /me/accounts?fields=access_token, but how do I tell AccessToken.CurrentAccessToken to use my pages access token instead?

现在我正在使用以下内容：

Right now i'm using the following:

var wwwForm = new WWWForm();
//wwwForm.AddField ("access_token", "A-T I NEED");
wwwForm.AddBinaryData("image", screenshot, "InteractiveConsole.png");
wwwForm.AddField("message", "herp derp.  I did a thing!  Did I do this right?");
FB.API("/PAGE-ID/photos", HttpMethod.POST, HandleResult, wwwForm);

我尝试手动放置访问令牌，但没有工作（所以我评论了）

I tried putting the access token manually, but that didn't work (so I commented it out).

有了这个，因为它是一个错误，告诉我，我需要 publish_actions ，这是不正确，因为我不想以用户身份发布。如果我也得到 publish_actions 邮政上线，而是以用户的身份发布到该页面。 （用户也是管理员）

With this as it is I'm getting an error, telling me that I need publish_actions, wich is not correct since I'm not trying to post as the user. If I also get publish_actions the Post goes online, but is posted to the page as the user speaking. (User is also Admin)

任何想法？谢谢！

推荐答案

所以，我向Facebook提交了一个错误报告，事实证明：...在这个时候这个功能是不支持。这意味着现在可以使用您通过 FB.API 在 FB.API 。他们不会在文档中告诉你。

So, I filed a bug report to facebook and as it turns out: "… at this time this functionality is not supported." Wich simply means there is now way to use the Page Access Token you acquired via the FB.API within the FB.API. And they are not going to tell you abot it in the documentation.

作为一种解决方法，我只需使用一个 UnityWebRequest 像这样：

As a workaround I simply use a UnityWebRequest like this:

IEnumerator UploadToPage(byte[] screenshot) {

    var wwwForm = new WWWForm();
    wwwForm.AddField("message", "herp derp.  I did a thing!  Did I do this right?");
    wwwForm.AddBinaryData("image", screenshot, "Test.png");

    string url = "https" + "://graph.facebook.com/"+ PageID + "/photos";
    url += "?access_token=" + PageAccessToken;

    using (UnityWebRequest www = UnityWebRequest.Post(url, wwwForm))

    {
        yield return www.Send();

        if (www.isError)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log("Form upload complete!");
        }
    }

    Debug.Log(url);
}
