如何在向用户时间线发布照片时创建Instagram类型的消息?

如果您在Instagram上分享照片,则会在时间线上的照片上方看到以下消息。

" FB用户在Instagram上拍照。"

我的测试目前只显示:

" FB用户3秒前通过AppName"

我的图片邮政编码是:

$args = Array(
    'url'           => 'http://www.mySiteName.com/imageName.png',
    'message'       => 'Made on SiteName http://www.mySiteName.com',
);
$post_id = $this->facebook->api("/me/photos", "post", $args);

我认为我需要设置OpenGraph动作和对象,我已经完成了,但我不确定我是否正确设置了它们或如何测试它们。

我创建了一个动作" Make"和一个对象"集合"并尝试了以下内容:

$post_id = $this->facebook->api("/me/Namespace:make", "post", $args);

但得到错误:

"您尝试发布的操作无效,因为它未指定任何参考对象。必须至少指定以下属性之一:集合。"

Collection Get Code给出:

 <head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# collection: http://ogp.me/ns/collection#">
  <meta property="fb:app_id" content="appId" /> 
  <meta property="og:type"   content="collection" /> 
  <meta property="og:url"    content="Put your own URL to the object here" /> 
  <meta property="og:title"  content="Sample Collection" /> 
  <meta property="og:image"  content="https://s-static.ak.fbcdn.net/images/devsite/attachment_blank.png" /> 

行动获取代码:

curl 'https://graph.facebook.com/me/nameSpace:make?access_token=TOKEN'

我已经设法让它工作,并在下面张贴了生成的帖子,参考URL和Codeigniter代码的图像。

Make是我的OpenGraph Action和Collection是我的OpenGraph对象。

在App控制台中添加OG操作的位置右侧会出现一个“获取代码”的链接。这将显示您需要包含的信息。

在您的情况下,您的args中应该有一个collection参数,其中包含包含照片OG标记的网页的网址。

您可以通过单击在应用控制台中创建的collection对象旁边的“获取代码”链接找到此标记。

通过将元标记添加到可访问网页的头部来打开图形。您需要将colleation元数据添加到某个页面,然后添加到您正在进行的请求中的collection参数中,添加页面的网址。
