使用Selenium Webdriver下载excel时如何处理firefox中的下载弹出窗口

Question

I am trying to download an Excel file from Firefox and Webdriver, but i can't handle the download pop-up.

When click on button i need the file to download automatically, without showing pop-up.

Here is my code:

FirefoxProfile firefoxProfile = new FirefoxProfile();
firefoxProfile.setPreference("browser.download.folderList", 2);
firefoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
firefoxProfile.setPreference("browser.download.dir", Constant.Downloaded_Path);
firefoxProfile.setPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv/xls/xlsx");
firefoxProfile.setPreference("browser.helperApps.neverAsk.openFile",
    "text/csv,application/x-msexcel,application/excel,application/x-excel,application/vnd.ms-excel,image/png,image/jpeg,text/html,text/plain,application/msword,application/xml");
firefoxProfile.setPreference("browser.helperApps.alwaysAsk.force", false);
firefoxProfile.setPreference("browser.download.manager.alertOnEXEOpen", false);
firefoxProfile.setPreference("browser.download.manager.focusWhenStarting", false);
firefoxProfile.setPreference("browser.download.manager.useWindow", false);
firefoxProfile.setPreference("browser.download.manager.showAlertOnComplete", false);
firefoxProfile.setPreference("browser.download.manager.closeWhenDone", false);
return firefoxProfile;

But, the above code is not working. Can any one help?

Answer 1

First you need to get the mime type corresponding to the file:

• Open Developer Tools and then the Network tab
• Go back to the page and click on the file to download
• Go back to the network panel and select the first request
• Copy the mime type on the right of Content-Type from the response header:

• Set the preference "browser.helperApps.neverAsk.saveToDisk" with your mime type
• Make sure the download folder "browser.download.dir" exists

Here is a working example with Firefox:

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", "C:\\Windows\\temp");
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.ms-excel");
profile.setPreference("pdfjs.disabled", true);  // disable the built-in PDF viewer

WebDriver driver = new FirefoxDriver(profile);
driver.get("http://www.exinfm.com/free_spreadsheets.html");
driver.findElement(By.linkText("Capital Budgeting Analysis")).click();

            FirefoxProfile profile = new FirefoxProfile();
            // profile.SetPreference("browser.helperApps.neverAsk.saveToDisk", " text/plain, application/octet-stream doc xls pdf txt");
            profile.SetPreference("browser.download.manager.alertOnEXEOpen", false);
            profile.SetPreference("browser.helperApps.neverAsk.saveToDisk", "application/csv, text/csv, text/plain,application/octet-stream doc xls pdf txt");
            profile.SetPreference("browser.download.manager.focusWhenStarting", false);
            profile.SetPreference("browser.download.useDownloadDir", true);
            profile.SetPreference("browser.helperApps.alwaysAsk.force", false);
            profile.SetPreference("browser.download.manager.closeWhenDone", true);
            profile.SetPreference("browser.download.manager.showAlertOnComplete", false);
            profile.SetPreference("browser.download.manager.useWindow", false);
            profile.SetPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);
            profile.SetPreference("pdfjs.disabled", true);
            _driverInstance = new FirefoxDriver(profile); 

These settings worked for me. Hope it might help you.

you need to provide mimetypes for the application you want to download. For python, if you want to enable it for all applications then use the following code

import mimetypes
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", ','.join(list(it for it in mimetypes.types_map.values())))
