我正在使用Reddit API（Pushshift）：https://github.com/pushshift/api
通过文档，我明白了如何使用它来提取在特定时间段内留下的每一条包含"covid"一词的评论：

https://api.pushshift.io/reddit/search/comment?q=covid&after=3h&before=2h&size=1

输出如下所示：

• • 我的问题：**假设我识别出一个包含"covid"一词的帖子--现在，我想检索这个帖子的每一条评论（不管它是否包含"covid"一词）：这可能做到吗？

例如，基于这些结果的输出，我看到：

• 链接标识：t3_116l7ct
• 父代编号：41917615743
• • 我是否可以使用此信息编写API查询来检索此帖子的所有评论？**

我尝试了以下查询，但得到的结果为空：https://api.pushshift.io/reddit/comment/search/?link_id=t3_116cjib
谢谢!

• • 注1：**是否可以使用"两阶段方法"执行这项任务？例如，第一阶段-确定评论中留下"covid"一词的帖子。第二阶段-开始提取该帖子的所有评论（无论是否包含"covid"）
• • 注意2：**我有一个当前正在使用的R脚本

library(jsonlite)

part1 = "https://api.pushshift.io/reddit/search/comment/?q=trump&after="    
part2 = "h&before="
part3 = "h&size=500"

results = list()
for (i in 1:10)
{tryCatch({
    {
        url_i<-  paste0(part1, i+1,  part2, i,  part3)
        r_i <-  fromJSON(url_i)
      
        results[[i]] <- data.frame(r_i$data$body , r_i$data$id, r_i$data$parent_id, r_i$data$link_id)
        
        #myvec_i <- sapply(results, NROW)
        
        #print(c(i, sum(myvec_i))) 
        print(i)
        #ifelse(i %% 200 == 0, saveRDS(results, "results_index.RDS"), "" )
    }
}, error = function(e){})
}

final = do.call(rbind.data.frame, results)

我可以修改这个脚本来获得想要的结果吗？
