Question

我想从httr包

获取带有r GET函数的hashtag的url

httr::GET("https://en.wikipedia.org/wiki/Kona_Lanes#Peak_years")

但是只返回hashtag之前的url。

另一个例子如下。 “第一”和“第二”页面的结果是

 library(httr)
 url1 = "example.com"
 url2 = "example.com#foo=bar"
 res1 <-  htmlTreeParse(GET(paste("https://www.",url1,sep="") ),useInternalNodes = TRUE)
 res2 <-  htmlTreeParse(GET(paste("https://www.",url2,sep="")),useInternalNodes = TRUE)

Answer 1

use %23 where # is present in URL

HTTR :: GET（ “https://en.wikipedia.org/wiki/Kona_Lanes%23Peak_years”）

Answer 2

什么不起作用和/或你期望与片段标识符有什么不同呢？没有它？

library(httr)
library(purrr)

res1 <- httr::GET("https://en.wikipedia.org/wiki/Kona_Lanes#Peak_years")
res2 <- httr::GET("https://en.wikipedia.org/wiki/Kona_Lanes%23Peak_years")
res3 <- httr::GET("https://en.wikipedia.org/wiki/Kona_Lanes")

txt1 <- content(res1, as="text")
txt2 <- content(res2, as="text")
txt3 <- content(res3, as="text")

identical(txt1, txt2)
## [1] TRUE

identical(txt2, txt3)
## [1] TRUE

identical(txt1, txt3)
## [1] TRUE
