如何仅基于 (post_id , comment_id) 获取 Reddit 评论？

Question

我有一个包含 (post_ids,comment_ids) 的文件。如何仅基于这两列提取 Reddit cmets？我没有任何其他信息，例如 SubReddit_name、url 等。

Answer 1

您可以仅使用评论 ID 提取评论数据。您可以使用 Reddit API 获取完整的评论 JSON 对象。这是example 的操作方法。我建议在它之上实施一个速率限制器，这样你就不会被列入黑名单（或者使用像 this 这样的内置速率限制的工具。

将评论 ID 传递给 Reddit API 时，请确保在它们前面加上 t1_ 前缀。因此，如果评论 id 是 hcve9uq，您将传递 t1_hcve9uq。

给定评论 ID 的 Reddit API 结果示例：

GET https://www.reddit.com/api/info.json?id=t1_hcve9uq
