c# - 在 Facebook c# sdk 中转换从调试 token 提交的 expires_at

Question

你好，我通过 debug_token 得到了一个 JsonObject，我需要知道什么是 expires_at/issued_at(什么是 dataType) 以及如何将其转换为 C# 的 DateTime。

只是我需要知道 Facebook 的 expires_at 是什么意思。是它死亡的时间(秒/分钟)还是正确的时间格式(DateTime)
我正在使用 Facebook C# SDK

我得到的JSON数组是:

{
    "data": {
        "app_id": *********,
        "is_valid": true,
        "application": "MyApp1",
        "user_id": *********,
        "issued_at": 1367606488,
        "expires_at": 1372790488,
        "scopes": [
            "create_note",
            "manage_notifications",
            "photo_upload",
            "publish_actions",
            "publish_stream",
            "read_stream",
            "share_item",
            "status_update",
            "user_about_me",
            "user_photos",
            "video_upload"
        ]
    }
}

Answer 1

这是 token 到期的时间，在 Unix Time 中格式，如上所示:

Unix time (also known as POSIX time or Epoch time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds. It is used widely in Unix-like and many other operating systems and file formats. Because it does not handle leap seconds, it is neither a linear representation of time nor a true representation of UTC. Unix time may be checked on most Unix systems by typing date +%s on the command line.
