代码实现 java + selenium 修改浏览器默认下载路径方法

System.setProperty("webdriver.chrome.driver", "driver/chromedriver-86.0.4240.exe");
ChromeOptions options = new ChromeOptions();
if(downloadPath!=null){
    //HashMap 中保存下载地址信息
    HashMap<String, Object> hashMap = new HashMap<>();
    hashMap.put("download.default_directory", "C:\\roy-temp");
    options.setExperimentalOption("prefs", hashMap);
            
}
DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
desiredCapabilities.setCapability(ChromeOptions.CAPABILITY, options);
WebDriver driver = new ChromeDriver(options);
