Selenium firefox配置文件永远不会要求不工作

Question

I am trying to save a csv file without the popup box. I followed the following link to figure out my mime:

http://watirmelon.com/2011/09/07/determining-file-mime-types-to-autosave-using-firefox-watir-webdriver/

I even added all the NC_values from the mimeTypes.rdf file. But, it does not seem to be working.

profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.folderList', 2)
profile.set_preference('browser.download.manager.showWhenStarting', False)
profile.set_preference('browser.download.dir', os.getcwd())
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'irc,ircs,webcal,application/csv,application/download,application/pdf')

mimeTypes.rdf

Answer 1

magic Python module says it's text/plain :

>>> import magic
>>> mime = magic.Magic(mime=True)
>>> mime.from_file("report.csv")
'text/plain'

The final preference (also leaving application/csv and application/download and adding application/octet-stream and text/csv to be safe):

profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'text/plain,text/csv,application/csv,application/download,application/octet-stream')
