推荐答案

我在您的代码中没有发现任何重大问题.但是，当您为 FirefoxProfile 类 setPreference 时，请记住添加此 Multipurpose Internet Mail Extensions="http://mimeapplication.net/" rel="nofollow noreferrer">网站.

I don't see any major issue in your code. But while you setPreference for the FirefoxProfile Class do remember to add all the relevant Multipurpose Internet Mail Extensions of CSV type files referred in this site.

这是您自己的代码块，其中添加了一些简单的调整:

Here is your own code block with some simple tweaks added to it:

String downloadFilepath = "C:\Utility\OP_Resources\MozillaFirefoxDownload";
System.setProperty("webdriver.gecko.driver", "C:\Utility\BrowserDrivers\geckodriver.exe");
FirefoxProfile Profile = new FirefoxProfile();
Profile.setPreference("browser.download.dir",downloadFilepath);
Profile.setPreference("browser.download.folderList",2);
//neverAsk - saveToDisk - CSV        
Profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/csv,application/excel,application/vnd.ms-excel,application/vnd.msexcel,text/anytext,text/comma-separated-values,text/csv,text/plain,text/x-csv,application/x-csv,text/x-comma-separated-values,text/tab-separated-values");
//neverAsk - saveToDisk - ANY       
Profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/xml,text/plain,text/xml,image/jpeg,application/octet-stream");
Profile.setPreference("browser.download.manager.showWhenStarting",false);
//neverAsk - openFile - CSV
Profile.setPreference("browser.helperApps.neverAsk.openFile","application/csv,application/excel,application/vnd.ms-excel,application/vnd.msexcel,text/anytext,text/comma-separated-values,text/csv,text/plain,text/x-csv,application/x-csv,text/x-comma-separated-values,text/tab-separated-values");
//neverAsk - openFile - ANY
Profile.setPreference("browser.helperApps.neverAsk.openFile","application/xml,text/plain,text/xml,image/jpeg,application/octet-stream");
Profile.setPreference("browser.helperApps.alwaysAsk.force", false);

我已在此 网站 和 Microsoft 验证了我的代码site 在我看来工作正常.

I have verified my code on this site and Microsoft site as well and seems to me works fine.
