请使用chrome功能查找以下代码。实际上,浏览器没有将文件下载到指定的路径。
private static DesiredCapabilities getChromeCapabilities() throws Exception {
String chromePath = BrowserUtil.class.getResource("/Browserdrivers/chromedriver.exe").getPath();
System.setProperty("webdriver.chrome.driver", chromePath);
String downloadFilepath = "C:\\TestDownloads";
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--test-type");
options.addArguments("start-maximized", "disable-popup-blocking");
DesiredCapabilities chromeCapabilities = DesiredCapabilities.chrome();
setProxy(chromeCapabilities);
chromeCapabilities.setPlatform(Platform.WINDOWS);
chromeCapabilities.setCapability("name", MDC.get("testname"));
chromeCapabilities.setCapability(ChromeOptions.CAPABILITY, options);
return chromeCapabilities;
}

对于Chromedriver尝试:
String downloadFilepath = "/path/to/download";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
cap.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(cap);
注意: - 在Windows中,您需要使用\\作为路径,而如果您使用的是linux或mac,则使用//
希望这会有所帮助。 :)

ans帮助我在Windows(https://bugs.chromium.org/p/chromedriver/issues/detail?id=783)上解决此问题。
Map<String, Object> prefs = new HashMap<String, Object>();
prefs.put("download.default_directory", System.getProperty("user.dir")+ File.separator + "externalFiles" + File.separator + "downloadFiles");
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", prefs);
ChromeDriver driver = new ChromeDriver(options);

对于Chrome驱动程序,以下代码对我有用
String downloadFilepath = "/path/to/download";
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", downloadFilepath);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
WebDriver driver = new ChromeDriver(options);

Chrome浏览器:v84
ChromeDriver:v83
JDK:OpenJDK 11(LTS)
将Paths类用于与平台无关的文件分隔符。
@Test
public void doFileDownload() throws Throwable {
// Since Java 7: Relative path from project root dir
// Put in target dir to avoid committing downloaded files
var downloadDir = Paths.get("target").toAbsolutePath().toString();
var prefs = new HashMap<String, Object>();
prefs.put("download.default_directory", downloadDir); // Bypass default download directory in Chrome
prefs.put("safebrowsing.enabled", "false"); // Bypass warning message, keep file anyway (for .exe, .jar, etc.)
var opts = new ChromeOptions();
opts.setHeadless(true);
opts.setExperimentalOption("prefs", prefs);
var driver = new ChromeDriver(opts); // ChromeDriver binary is added to PATH env var
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);
driver.manage().window().maximize();
driver.get("https://the-internet.herokuapp.com/download");
var downloadLink = driver.findElement(By.cssSelector("a[href*='some-file.txt']"));
var downloadHref = downloadLink.getAttribute("href").replace(":", "");
var downloadFileName = Paths.get(downloadHref).getFileName().toString();
downloadLink.click();
// Wait download to finish for 60s
var downloadFilePath = Paths.get(downloadDir, downloadFileName);
new WebDriverWait(driver, 60).until(d -> downloadFilePath.toFile().exists());
// Since Java 11: Read content of downloaded file
var content = Files.readString(downloadFilePath);
// Do tests with string content...
log.info("Content={}", content);
driver.quit();
}
输出:
在任何运行之前执行mvn clean
还可以避免必须覆盖现有文件。

对于查看此页面的Python用户-这是我在Python Selenium中设置下载目录的方式(这只是Shubham接受的答案的Python版本):
def newChromeBrowser(headless=True, downloadPath=None):
""" Helper function that creates a new Selenium browser """
options = webdriver.ChromeOptions()
if headless:
options.add_argument('headless')
if downloadPath is not None:
prefs = {}
os.makedirs(downloadPath)
prefs["profile.default_content_settings.popups"]=0
prefs["download.default_directory"]=downloadPath
options.add_experimental_option("prefs", prefs)
browser = webdriver.Chrome(chrome_options=options, executable_path=CHROMEDRIVER_PATH)
return browser

为了让它更干净简单,我开发了一个library,可让您生成一个ChromeOptions对象,其中包含您的下载文件夹。例如,要定义&#34; / tmp / downloads&#34;,请使用:
private SeleniumDownloadKPI seleniumDownloadKPI;
@BeforeEach
void setUpTest() {
// New instance of SeleniumDownloadKPI with given download folder.
seleniumDownloadKPI =
new SeleniumDownloadKPI("/tmp/downloads");
ChromeOptions chromeOptions =
seleniumDownloadKPI.generateDownloadFolderCapability();
driver = new ChromeDriver(chromeOptions);
library还包含允许接收下载KPI并执行断言的方法。
