C＃：Firefox webdriver：如何將文件下載到特定文件夾

Question

美好的一天。

我嘗試設置firefox webdriver的選項以下載到特定的foler。我把我的代碼放在下面。它在最後一行引發TypeInitializationException。

如何設置文件下載的默認文件夾，並設置它應該沒有警報窗口？

var firefoxOptions = new FirefoxOptions(); 
firefoxOptions.AddAdditionalCapability("browser.download.folderList", 2);   firefoxOptions.AddAdditionalCapability("browser.download.manager.showWhenStarting", false); 
firefoxOptions.AddAdditionalCapability("browser.download.dir", Constants.DownloadFilesLocation); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/jpeg"); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/png"); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/gif"); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/bmp"); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/tiff"); 
Driver = new FirefoxDriver(firefoxOptions); 

Answer 1

我認爲你應該將能力值定義爲字符串。此外，browser.helperApps.neverAsk.saveToDisk應該定義爲一個逗號分隔的列表：

var firefoxOptions = new FirefoxOptions(); 

firefoxOptions.AddAdditionalCapability("browser.download.folderList", "2"); 
firefoxOptions.AddAdditionalCapability("browser.download.manager.showWhenStarting", "false"); 
firefoxOptions.AddAdditionalCapability("browser.download.dir", Constants.DownloadFilesLocation); 
firefoxOptions.AddAdditionalCapability("browser.helperApps.neverAsk.saveToDisk", "image/jpeg, image/png, image/gif, image/bmp, image/tiff"); 

Driver = new FirefoxDriver(firefoxOptions); 

此外，檢查Constants.DownloadFilesLocation是一個下載目錄路徑字符串。
