通过Selenium下载文件的旧方法似乎不再起作用。
我的代码是:
fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.dir", os.getcwd())
fp.set_preference("browser.download.folderList", 2)
fp.set_preference("browser.download.manager.showWhenStarting", False)
fp.set_preference("browser.helperApps.neverAsk.saveToDisk",
"application/pdf")
self.driver = webdriver.Firefox(firefox_profile=fp)
self.longMessage = True
但是,仍会显示文件对话框。我已经完成了相当多的切换字段,但经过一些挖掘后,我发现Selenium生成的默认Firefox配置文件的prefs.js
文件与prefs.js
之间没有差异。我在下载对话框中手动选中“从现在开始自动执行此类文件”的文件。
mimeTypes.rdf
文件确实发生了变化,具体而言,添加了以下行:
<RDF:Description RDF:about="urn:mimetype:handler:application/pdf"
NC:alwaysAsk="false"
NC:saveToDisk="true"
NC:handleInternal="false">
<NC:externalApplication RDF:resource="urn:mimetype:externalApplication:application/pdf"/>
但是,我不知道在创建新的Firefox配置文件时设置自定义mimeTypes.rdf文件的方法。有没有人有任何想法?
为了抢先任何人建议我只是下载URL,为用户生成文件,我需要专门验证.pdf文件是否已下载到驱动器。

我是R用户,所以只需使用RSelenium在R中发布我的解决方案。如果你无法在python中转换它,请告诉我,我会暗示同样的。
known_formats <- c("application/vnd.ms-excel","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
firefox_profile.me <- makeFirefoxProfile(list(marionette = TRUE,
# this is for certificate issues [may be ignored]
webdriver_accept_untrusted_certs = TRUE,
webdriver_assume_untrusted_issuer = TRUE,
# download related settings
browser.download.folderList = 2L,
browser.download.manager.showWhenStarting = FALSE,
# put your path here but remember to give path like C:\\DirOfYourChoice and not C:\\DirOfYourChoice\\ [last \\ is not going to work]
browser.download.dir = normalizePath("TestDL"),
browser.helperApps.alwaysAsk.force = FALSE,
browser.helperApps.neverAsk.openFile = paste0(known_formats, collapse = ","),
browser.helperApps.neverAsk.saveToDisk = paste0(known_formats, collapse = ","),
browser.download.manager.showWhenStarting = FALSE,
# this is for marionette and related security
"browser.tabs.remote.force-enable" = TRUE,
pdfjs.disabled = TRUE))
remDr <- remoteDriver(remoteServerAddr = "localhost",
port = 4444,
browserName = "firefox",
extraCapabilities = firefox_profile.me)
remDr$open()
remDr$navigate("https://www.google.com/search?q=sample+xlsx")
remDr$findElement(using = "css selector", value = ".g:nth-child(1) a")$clickElement()
remDr$navigate("https://www.google.com/search?q=test+xls")
remDr$findElement(using = "css selector", value = ".g:nth-child(1) a")$clickElement()
和我一起工作 我正在使用
Firefox 50.1.0 [while I'm writing this post]
Selenium [3.0.1]
R [3.3.2 (2016-10-31)]
希望你能将它移植到python。只是尝试在firefox makeFirefoxProfile

您可以通过链接创建从互联网下载文件的其他方法。
来自我的c#代码示例:
public Bitmap Image
{
get
{
string webPath = Element.GetAttribute("src");
if (webPath != string.Empty)
{
try
{
System.Net.WebRequest request =
System.Net.WebRequest.Create(webPath);
System.Net.WebResponse response = request.GetResponse();
System.IO.Stream responseStream = response.GetResponseStream();
Bitmap bitmapImg = new Bitmap(responseStream);
return bitmapImg;
}
catch (System.Net.WebException)
{
}
}
return new Bitmap(1,1);
}
}
所以如你所见,在这段代码中我从image元素获取src属性并从浏览器下载它以获得绝对正确的位图图像(之后我可以将其保存到HDD)。 通过相同的方式,您可以从links =)
