图形图像的故事上传 [英] Graph Story Image Upload

问题描述

我工作的一个Android应用程序，它可以让你发布一个故事，我希望用户上传照片。

I'm working on an Android app which lets you post a story and I want the user to upload a photo.

该应用程序具有publish_actions权限，它已user_generated，FB：explicitly_shared。

The app has the "publish_actions" permission and it has "user_generated", "fb:explicitly_shared".

我的code是以下

ByteArrayOutputStream stream = new ByteArrayOutputStream();
    if(bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream)) {
        Log.i(TAG,"Bitmap compressed into stream successfully.");
    }

    postParams.putByteArray("image", stream.toByteArray());

    postParams.putString("user_generated", "true");
    postParams.putString(OBJECT,URL);
    postParams.putString("fb:explicitly_shared", "true");

Log.i(TAG,"Executing facebook graph story request...");

    Request request = new Request(session, "me/<appnamespace>:<action>", postParams, HttpMethod.POST, callback);
    RequestAsyncTask task = new RequestAsyncTask(request);
    task.execute();

当我检查测试帐户时间轴的故事被张贴，但没有图像。我想这个问题是在这条线：

When I check the test account timeline the story is posted, but there is no image. I suppose the problem is on this line:

postParams.putByteArray("image", stream.toByteArray());

我认为这个问题是无论哪种方式，关键是不是形象，或者不是你是怎么做到的。

I think the problem is either way the key is not "image" or that's not how you do it.

什么是做到这一点的正确方法？

What's the right way to do this?

推荐答案

从我的评论在您的其他问题：

From my comment in your other question:

您不能上传图片到你的我/：端点。你需要它的第一篇文章给我/ staging_resources。怎么看这个，对使用对象的API（特别是第3步图像上载）。

You can't upload an image to your me/: endpoint. You need to POST it to me/staging_resources first. See this how-to on using the Object API (specifically step 3 for image uploading).

的https://developers.facebook.com/docs/howtos/androidsdk/3.0/share-using-object-api/

要将图像添加到您的Open Graph的动作，做这样的事情：

To add the image to your open graph action, do something like:

JSONObject obj = new JSONObject();
obj.put("url", <your staging uri here>);
obj.put("user_generated", true);
myAction.setImage(Arrays.asList(obj));
