我已尝试过各种可用的方法从Chrome下载PDF报告，而无需打开新的PDF查看器标签 . 我想直接在本地驱动器上下载PDF . 我正在使用Coypu来开发我的自动化框架我正在使用的代码如下：
BrowserSession _session;
ChromeOptions options = new ChromeOptions();
String downloadFilepath = @"C:\Users\3682143\Downloads";
Dictionary<String,Object> chromeOptionsMap = new Dictionary<String, Object>();
chromeOptionsMap.Add("plugins.plugins_disabled", new String[] {"Chrome PDF Viewer"});
chromeOptionsMap.Add("download.default_directory", downloadFilepath);
chromeOptionsMap.Add("plugins.always_open_pdf_externally", true);
chromeOptionsMap.Add("download.prompt_for_download", false);
chromeOptionsMap.Add("pdfjs.disabled", true);
options. AddUserProfilePreference("prefs", chromeOptionsMap);
DesiredCapabilities desiredCap = DesiredCapabilities.Chrome();
desiredCap.SetCapability(CapabilityType.AcceptSslCertificates, true);
desiredCap.SetCapability(ChromeOptions.Capability, options);
_session = new BrowserSession(sessionConfig, new CustomExplorerProfileSeleniumWebDriver(desiredCap));
