使用Javascript Graph API在Facebook上发布等角360°全景图

问题描述

我正在代表我的应用程序的用户发布360°的照片，但是我无法确定如何使其工作。

I am trying to post 360° photos on behalf of my app's users, but I can't figure out how to make it work.

我加载了Facebook Javascript Graph API，使用publish_actions范围记录用户，并使用以下代码使用等角投影来发布图片：

I loaded the Facebook Javascript Graph API, logged the user with "publish_actions" scope and used the following code to post a picture using equirectangular projection:

FB.api(
        "/me/photos",
        "POST",
        {
            "url": "MY_PUBLIC_URL",
            "allow_spherical_photo": true,
            "spherical_metadata": {
                "ProjectionType": "equirectangular",
                "CroppedAreaImageWidthPixels": 240,
                "CroppedAreaImageHeightPixels": 240,
                "FullPanoWidthPixels": 1962,
                "FullPanoHeightPixels": 981,
                "CroppedAreaLeftPixels": 981,
                "CroppedAreaTopPixels": 490
            }
    }, function (response) {
        console.log(response); // I get "{"id":"...", post_id:"..."} so no error
        if (response && !response.error) {
          /* handle the result */
        }
    }
);

在当前用户的时间轴上正确发布，但显示为正常图片，没有一个360度的全景照片。

It is posting correctly on the current user's timeline, but it is shown as a "normal" picture, not a 360° panorama.

有人实现了360°全景照片功能吗？

Did someone implement a 360° panorama posting feature that works?

我的照片应该具有正确的比例（2：1），并且是正确的360°照片。

My photo should have the correct ratio (2:1) and is a correct 360° photo.

提前谢谢您的帮助。

推荐答案

我终于找到了一个解决问题的解决方案：只需将allow_spherical_photo：true 并删除 spherical_metadata 。

I finally found a working solution for my issue: only put "allow_spherical_photo": true and remove spherical_metadata.

然后，360°图片需要有它们的元数据，以便Facebook处理显示它们（XMP元数据如下所述：）

Then, the 360° pictures need to have metadata on them, in order for the Facebook processing to display them properly (XMP metadata as explained here: https://developers.google.com/streetview/spherical-metadata)

谢谢。
