我正在尝试逐页下载来自 FACEBOOK 公开帖子的公开评论和回复。
我的代码一直工作到 18 年 2 月 5 日,现在它显示以下“回复”错误。
Error in data.frame(from_id = json$from$id, from_name = json$from$name, :
arguments imply differing number of rows: 0, 1
Called from: data.frame(from_id = json$from$id, from_name = json$from$name,
message = ifelse(!is.null(json$message), json$message, NA),
created_time = json$created_time, likes_count = json$like_count,
comments_count = json$comment_count, id = json$id, stringsAsFactors = F)
请参考下面我正在使用的代码。
data_fun=function(II,JJ,page,my_oauth){
test <- list()
test.reply<- list()
for (i in II:length(page$id)){
test[[i]] <- getPost(post=page$id[i], token = my_oauth,n= 100000, comments = TRUE, likes = FALSE)
if (nrow(test[[i]][["comments"]]) > 0) {
write.csv(test[[i]], file = paste0(page$from_name[2],"_comments_", i, ".csv"), row.names = F)
for (j in JJ:length(test[[i]]$comments$id)){
test.reply[[j]] <-getCommentReplies(comment_id=test[[i]]$comments$id[j],token=my_oauth,n = 100000, replies = TRUE,likes = FALSE)
if (nrow(test.reply[[j]][["replies"]]) > 0) {
write.csv(test.reply[[j]], file = paste0(page$from_name[2],"_replies_",i,"_and_", j, ".csv"), row.names = F)
}}}
}
Sys.sleep(10)}
感谢您的支持提前。
