R中有沒有HTTP庫？

Question

我需要使用R進行HTTP POST命令。有沒有任何R http庫可以做到這一點？

Answer 1

是，RCurl

library(RCurl) 
# example from the vignette: 
x = postForm('http://www.wormbase.org/db/searches/advanced/dumper', 
    species="briggsae", 
    list="", 
    flank3="0", 
    flank5="0", 
    feature="Gene Models", 
    dump = "Plain TEXT", 
    orientation = "Relative to feature", 
    relative = "Chromsome", 
    DNA ="flanking sequences only", 
    .cgifields =c("feature", "orientation", "DNA", "dump", "relative")) 

如果你想在發佈實體和頭細粒度的控制，你可以直接使用curlPerform。
