I am trying to find out how to upload a file using R/RSelenium. Informations:
I tried the top comment from this SO question:
How to upload file using Selenium WebDriver in Java
Example:
url <- "https://www.freepdfconvert.com/pdf-word"
path <- "C:/path_to_folder/filename.pdf"
remDr$navigate(url)
upload_btn <- remDr$findElement(using = "id", "clientUpload")
upload_btn$sendKeysToElement(path)
But I get the following error message:
Selenium message:java.lang.String cannot be cast to java.util.List
Error: Summary: UnknownError
Detail: An unknown server-side error occurred while processing the command.
class: java.lang.ClassCastException
Further Details: run errorDetails method
The folder used is mapped to the virtual machine. Autoit is out of the question since it only works on Windows.
Also tried upload_btn$sendKeysToElement(list(path))
which does not return an error, but it is not working either.
Any help is appreciated.
Edit :
I think this is supposed to be working but I am seeing an error when viewing a screenshot:
default
virtual machine as a shared folder and named it win_share
default
with sudo mkdir vm_share
win_share
to the folder vm_share
with sudo mount -t vboxsf win_share vm_share
. After this step I can successfully access my working folder on the virtual machine (checked by ssh
into default
). /home/docker/vm_share
After all of these executing this script it doesn't work. (took John's example)
library(RSelenium)
remDr <- remoteDriver(remoteServerAddr = "192.168.99.100"
, port = 4445L
, browserName = "chrome"
)
remDr$open()
remDr$navigate("https://gallery.shinyapps.io/uploadfile")
webElem <- remDr$findElement("id", "file1")
# create a dummy csv
x <- data.frame(a = 1:4, b = 5:8, c = letters[1:4])
write.csv(x, file = "testcsv.csv", row.names = FALSE)
# post the file to the app
path <- "/home/docker/vm_share/testcsv.csv"
webElem$sendKeysToElement(list(path))
remDr$close()
remDr$closeServer()
Screenshot :
The sendKeysToElement
method expects a list. The path needs to be passed as a list:
library(RSelenium)
appURL <- "https://www.freepdfconvert.com/pdf-word"
# create sample pdf
tfile <- tempfile("sample", fileext = ".pdf")
pdf(tfile,width=7,height=5)
x=rnorm(100)
y=rnorm(100,5,1)
plot(x,lty=2,lwd=2,col="red")
lines(y,lty=3,col="green")
dev.off()
rD <- rsDriver()
remDr <- rD$client
remDr$navigate(appURL)
upload_btn <- remDr$findElement(using = "id", "clientUpload")
upload_btn$sendKeysToElement(list(tfile))
......
# cleanup when finished
rm(rD)
gc()
