我正在尝试excel使用 selenium下载档案firefox。

def download_driver(location_for_download):
    profile = webdriver.FirefoxProfile()
    profile.set_preference("browser.download.folderList", 2)
    profile.set_preference("browser.download.manager.showWhenStarting", False)
    profile.set_preference("browser.download.dir", location_for_download)
    profile.set_preference("browser.helperApps.neverAsk.saveToDisk",
                           "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
    profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/csv")
    profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/plain")
    profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/comma-separated-values")
    profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/xls")
    driver = webdriver.Firefox(firefox_profile=profile)
    return driver

当我在脚本中使用这个函式时，会弹出保存档案的对话框。我在ubuntu。我认为这MIME-type是错误的，我已经添加了所有我能想到和搜索的内容。

有问题的档案显示为2007 excel spreadsheet.

找到正确的MIME type：

将以下内容添加到函式中使其作业：

profile.set_preference("browser.helperApps.neverAsk.saveToDisk",
                           "application/vnd.ms-excel application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")

把这个问题搁置一旁，以防其他人来找。

有点不同的解决方案，但作业得非常可靠。

profile = FirefoxProfile()
