Question

我正在使用R中的twitteR库，并想知道是否有可能获得与搜索或时间表相关联的时间戳。 E.G如果使用searchTwitter搜索#rstats，我想知道推文发布的时间......是否需要解析其他参数以获取该信息？

这是一些示例代码......

library(twitteR)
searchTwitter("#rstats",n=10)

给出以下结果

Answer 1

谷歌之后

：

 mytweet <- searchTwitter("#chocolate",n=10)
 str(mytweet[[1]])

Reference class 'status' [package "twitteR"] with 10 fields
 $ text        : chr "The #chocolate part of the #croquette. #dumplings #truffles http://t.co/Imwt3tTP"
 $ favorited   : logi FALSE
 $ replyToSN   : chr(0) 
 $ created     : POSIXct[1:1], format: "2013-01-27 16:26:03"
 $ truncated   : logi FALSE
 $ replyToSID  : chr(0) 
 $ id          : chr "295568362526896128"
 $ replyToUID  : chr(0) 
 $ statusSource: chr "&lt;a href=&quot;http://instagr.am&quot;&gt;Instagram&lt;/a&gt;"
 $ screenName  : chr "tahiatmahboob"
 and 33 methods, of which 22 are possibly relevant:
   getCreated, getFavorited, getId, getReplyToSID, getReplyToSN, getReplyToUID, getScreenName, getStatusSource, getText, getTruncated,
   initialize, setCreated, setFavorited, setId, setReplyToSID, setReplyToSN, setReplyToUID, setScreenName, setStatusSource, setText,
   setTruncated, toDataFrame

所以时间戳是：

mytweet[[1]]$created
[1] "2013-01-27 16:26:03 UTC"

在我阅读您的问题之前，从未使用twitteR。无聊时似乎很有趣。

Answer 2

解析结果的一个替代方案（如上面的答案）是使用参数从和直到。

例如，你可以这样做：

 res <- searchTwitter("#rstats",n=1000,since='2013-01-24',
                                       until='2013-01-28')

searchTwitter是twitter的JSON API的包装器。请查看here以获取有关参数和JSON结果示例的更多详细信息。
