Question

我的任务是将使用python urllib的一小段python代码移植到R。这是完整的python代码：

import urllib.parse
import urllib.request

url = "https://www.uniprot.org/uploadlists/"

params = {
  "from": "ACC+ID",
  "to": "ENSEMBL_ID",
  "format": "tab",
  "query": "P40925 P40926 O43175 Q9UM73 P97793"
}

data = urllib.parse.urlencode(params)
data = data.encode("utf-8")
req = urllib.request.Request(url, data)
with urllib.request.urlopen(req) as f:
  response = f.read()
print(response.decode("utf-8"))

我不希望使用paste和paste0在R中手动构建url。我发现的是R urltools包。但这并不能像urllib.parse.urlencode那样对数据进行url编码。

用于重新实现python代码的R包是什么？还是应该使用reticulate？

谢谢

我认为httr应该完成工作：

url <- "https://www.uniprot.org/uploadlists/"

params = list(
  from = "ACC+ID",
  to = "ENSEMBL_ID",
  format = "tab",
  query = "P40925 P40926 O43175 Q9UM73 P97793"
)

r <- httr::POST(url, body = params, encode = "form")
cat(httr::content(r))
#> No encoding supplied: defaulting to UTF-8.
#> From To
#> P40925   ENSG00000014641
#> P40926   ENSG00000146701
#> O43175   ENSG00000092621
#> Q9UM73   ENSG00000171094
#> P97793   ENSMUSG00000055471

^{由reprex package（v0.3.0.9000）于2019-09-02创建}

哪个R包提供类似于python urllib的功能
