I'm trying to access a website, fill out their form, and download the file, but I'm having some difficulties.
This is my code so far:
#library's require(rvest) #website url <- ("http://www.anbima.com.br/est_termo/Curva_Zero.asp") pgsession <- html_session(url) pgform <-html_form(pgsession)[] param <- set_values(pgform, "escolha" = "2", "Dt_Ref" = Sys.Date() ) submit <- submit_form(pgsession, form = param, "Consultar")
But it returns an error when submitting the submit:
Erro: Could not find possible submission target.
Can someone help me?
As discussed with the friend above, the result was much easier than imagined:
download.file("http://www.anbima.com.br/est_termo/CZ-down.asp", destfile = "")
