使用 statuses/user_timeline API 从推文中获取图像和外部 URL

Question

我希望提取推文中出现的外部 URL 的价值。加上该 URL 生成的 Thumbnail。

示例推文：

http://prntscr.com/ogdqey

https://twitter.com/JarirBookstore/status/1151506848387870720

来自 Twitter statuses/user_timeline API 的输出 -

{
    "created_at": "Wed Jul 17 15:00:01 +0000 2019",
    "id": 1151506848387870720,

                "text": "صيف_هواوي",
                "indices": [
                    5,
                    15
                ]
            }
        ],
        "symbols": [],
        "user_mentions": [],
        "urls": []
    },
    "source": "<a href=\"https:\/\/ads-api.twitter.com\" rel=\"nofollow\">Twitter Ads Composer<\/a>",

URL 实体是一个空白数组。如果链接不存在于推文本身，API 不会在 URL 实体中返回它。我试过有无tweet_mode=extended

令人惊讶的是，Twitter 确实为少数此类推文返回 URL。下面是一个例子。

API 响应：

为什么响应是随机的？它确实返回比尔盖茨推文的 URL，但不返回我之前问题中提到的那个。

如何让 Twitter 显示外部 URL 和缩略图？

我的最终 API 调用 -

https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=jarirbookstore&count=100&exclude_replies=true&trim_user=true&include_rts=false&tweet_mode=extended

Answer 1

你提供的两个示例中的第一个是由 Twitter 广告平台发布的，因此附加的卡片不是推文的一部分。无法通过 API 获得。在第二种情况下，URL 是 Tweet 文本的一部分，因此它也是 URL 实体对象的一部分。
