R：使用POST请求启动Rselenium吗？

Question

是否可以通过POST请求启动RSelenium？ 我发现了这个问题：Is there any way to start with a POST request using Selenium?

但是，它有些旧，并且不专门针对RSelenium。

library(RSelenium)
library(rvest)


url <- "https://www.ema.europa.eu/en/medicines"
pgsession<-html_session(url)
pgform<-html_form(pgsession)[[1]]
pgform


page<-rvest:::request_POST(pgsession,url,
                           body=list(
                             `op`="opioid"

                           ),
                           encode="form")
rD <- rsDriver()
rD(page) #Obviously, this does not work, but I wonder if RSelenium could be started somehow from/with a post request
