硒问题

Question

I'm trying to scrape a website using Rselenium. However I'm getting an error:

Error: checkForServer is now defunct. Users in future can find the function in 
file.path(find.package("RSelenium"), "examples/serverUtils"). The
recommended way to run a selenium server is via Docker. Alternatively
see the RSelenium::rsDriver function.

My chrome is updted to version 58 and moxilla to version 45, rselenium used to work earlier but I'm not sure what happened please help guys.

Answer 1

The following script works for me with the new RSelenium...

rD <- rsDriver(port=4444L,browser="chrome")
remDr <- rD$client
remDr$navigate(url)

Answer 2

Just make sure you have docker account and you have it installed.

try this

library('RSelenium')
rD=rsDriver()
remDr =rD[["client"]]
remDr$navigate("https://www.vinmonopolet.no/vmp/Land/Chile/Gato-Negro-Cabernet-Sauvignon-2017/p/295301")
webElement = remDr$findElement('xpath', '//*[@id="product_2953010"]/span[2]')
webElement$clickElement()
