Answer 1

根据 Facebook 的说法，这是设计好的。来自 this Facebook developers bug report (需要登录 Facebook 才能查看):

Hi Facebook Developers,

This issue is going to be closed by design because our API does not support pre-filling the message for users as seen in our Policy Documentation here (https://developers.facebook.com/docs/guides/policy/application_integration_points/) under Platform Policy IV.2.

注意:上面提供的链接已损坏； Facebook 平台政策的当前链接在这里:https://developers.facebook.com/policy/#integration (强调):

IV. Application Integration Points

1. [...]
2. You must not pre-fill any of the fields associated with the following products, unless the user manually generated the content earlier in the workflow: Stream stories (user_message parameter for Facebook.streamPublish and FB.Connect.streamPublish, and message parameter for stream.publish), Photos (caption), Videos (description), Notes (title and content), Links (comment), and Jabber/XMPP.

因此 Facebook 应用程序只是强制执行此操作 — 如果您尝试分享带有预填文本的内容，Facebook 不知道它是由用户编写还是由应用程序填写，因此它不会做出任何假设，忽略该文本，并要求用户编写文本。
