Post Facebook 群组上的照片使用图表 api

Question

我正在为 Facebook 群组开发 android 应用程序。使用图表 API，我可以轻松地 post 文本状态，但是当我上传照片时，它 returns 错误提示

(#100) The picture is not properly formatted

如果我使用与 post 相同的代码到 my 墙，照片上传工作正常。

这是 API 限制还是有单独的方法可以将照片上传到群组？

以下是我的代码：

Request photoRequest = Request.newUploadStagingResourceWithImageRequest(session, bitmap, new Request.Callback() {
        @Override
        public void onCompleted(Response response) {
            if (mProgress != null && mProgress.isShowing())
                mProgress.dismiss();

            if (response.getError() == null) {
                Toast.makeText(NewPostActivity.this, "Successfully shared on the group", Toast.LENGTH_SHORT).show();
                finish();
            } else {
                Toast.makeText(NewPostActivity.this, "Facebook sharing error: " + response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
            }

        }
    });
    Bundle params = photoRequest.getParameters();
    if(message != null) {
        params.putString("message", message);
    }
    if(imageBytes != null) {
        params.putByteArray("picture", imageBytes);
    }
    photoRequest.setParameters(params);
    photoRequest.setHttpMethod(HttpMethod.POST);
    photoRequest.setGraphPath(Constants.URL_FEEDS);
    photoRequest.executeAsync();

编辑我正在使用 Graph API v2.3

Answer 1

似乎可以 post 一组照片。

You can make a POST request to photos edge from the following paths:

/{group_id}/photos

When posting to this edge, a Photo will be created.

Link Return类型

Struct {
    id: numeric string,
    post_id: token with structure: Post ID,
    }

Answer 2

对 /<group-id>/feed 的 POST 请求似乎不允许上传照片（否则对 /me/feed 有效）。我终于按照建议使用 /<group-id>/photos 边缘进行了此操作。以下是我的代码 - 希望它对某些人有所帮助：

Request photoRequest = Request.newUploadStagingResourceWithImageRequest(session, bitmap, new Request.Callback() {
        @Override
        public void onCompleted(Response response) {
            if (mProgress != null && mProgress.isShowing())
                mProgress.dismiss();

            if (response.getError() == null) {
                Toast.makeText(NewPostActivity.this, "Successfully shared on the group", Toast.LENGTH_SHORT).show();
                finish();
            } else {
                Toast.makeText(NewPostActivity.this, "Facebook sharing error: " + response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
            }

        }
    });

    Bundle params = photoRequest.getParameters();
    if(message != null) {
        params.putString("message", message);
        photoRequest.setGraphPath(Constants.URL_FEEDS);
    }
    if(imageBytes != null) {
        params.putByteArray("picture", imageBytes);
        photoRequest.setGraphPath(Constants.URL_PHOTOS);
    }
    photoRequest.setParameters(params);
    photoRequest.setHttpMethod(HttpMethod.POST);
    photoRequest.executeAsync();
