Facebook API / Android：Wall Post发布与图像附件不工作 [英] Facebook API / Android : Wall Post publish with image attachment not working

问题描述

我有以下代码。

它工作并发布消息部分，但附件部分不工作。
我怀疑这是将JSON作为一个字符串传递。

It works and posts the message-part but the attachment part does'nt work. I suspect it has to do with passing a JSON as a string.

Facebook返回{id：23522646737635675 。所以它不是一个错误。

Facebook returns "{"id":"23522646737635675"}. So its not an error.

        Bundle params = new Bundle();

        params.putString("message", message);

        JSONObject attachment = new JSONObject();

        attachment.put("href", URLEncoder.encode("http://a.espncdn.com/photo/2010/0523/pg2_a_cricket_576.jpg"));
        attachment.put("name", "Cricket Fantasy");
        attachment.put("caption", "New team");
        attachment.put("description","Description about Application");

        JSONObject media = new JSONObject();

        media.put("type", "image");
        media.put("src", URLEncoder.encode("http://a.espncdn.com/photo/2010/0523/pg2_a_cricket_576.jpg"));
        media.put("href", URLEncoder.encode("http://a.espncdn.com/photo/2010/0523/pg2_a_cricket_576.jpg"));
        attachment.put("media", media);

        params.putString("attachement", attachment.toString());

        String response = mFacebook.request("me/feed", params, "POST");

推荐答案

您不能将json编码数据发送到Facebook，这样不行。
每个参数都应该在POST正文中。

You can't send json encoded data to facebook, doesn't work that way. Each parameter should be on it's on in the POST body.

此外，附件方式是旧的，不再使用。
应该看起来像：

In addition, the "attachment" way is an old one and not used anymore. It should look something like:

Bundle params = new Bundle();

params.putString("message", message);
params.put("name", "Cricket Fantasy");
params.put("caption", "New team");
params.put("description","Description about Application");
params.put("url", URLEncoder.encode("http://a.espncdn.com/photo/2010/0523/pg2_a_cricket_576.jpg"));

String response = mFacebook.request("me/feed", params, "POST");

可以在这里找到使用网址上传图片的官方参考：通过URL将照片上传到Graph API 。
可以在用户对象中找到发布到Feed的参数 doc。

An official reference for uploading images using urls can be found here: Uploading Photos to the Graph API via a URL. The parameters for posting to a feed can be found in the User object doc.
