如何使用RSelenium保存文件並從下載對話框中單擊確定？
[英]How to save file and click ok from download dialog box using RSelenium?
問題描述
我有以下 HTML：
<a href='file.php?jobid=705945&coeffi=0&model=0&filetype=model_bz2'>Download all Models for all Coefficients</a>
使用此代碼，我嘗試下載文件
library(RSelenium)
webpage <- "https://cluspro.bu.edu/models.php?job=705945"
browser <- remoteDriver(port = 5556)
browser$open()
browser$navigate(webpage)
clk <- browser$findElement(using = "link text", "Use the server without the benefits of your own account")
clk$clickElement()
dnl_models <- browser$findElement(using = "link text", "Download all Models for all Coefficients")
dnl_models$clickElement()
然后它把我帶到一個這樣的對話框：

將以下內容添加到您現有的設置中，其中一些您可能已經擁有，僅在此處顯示以進行說明，基本上抑制下載彈出窗口，並且從不要求保存該 mime 類型 (bz2)
require(RSelenium)
dirdownload <- paste0(getwd(), "/path_to/my_output_dir/") %>% stringr::str_replace_all("/", "\\\\\\\\") # this is an old bug that had issues with the linux / mac os path slashes, this was the workaround
fprof <- makeFirefoxProfile(list(browser.download.dir = dirdownload,
browser.download.folderList = 2,
browser.download.manager.showWhenStarting = FALSE,
browser.helperApps.neverAsk.saveToDisk = "application/x-bzip2"))
RSelenium::startServer()
remDr <- remoteDriver(extraCapabilities = fprof)

要在工作目錄中下載，您可以嘗試，
library(stringr)
fold = str_replace_all(getwd(), '/', '\\\\')
fprof <- makeFirefoxProfile(list(browser.download.dir = fold,
browser.download.folderList = 2,
browser.download.manager.showWhenStarting = FALSE,
browser.helperApps.neverAsk.saveToDisk = "application/x-bzip2"))
