java - 无法使用 Selenium ChromeDriver SerenityBDD 设置默认下载路径

Question

问题:

1. ChromeDriver 未将文件下载到“所需”路径

2. ChromeDriver 无法在“ headless ”模式下下载任何文件。

POM

        <java.version>1.8</java.version>
        <serenity.version>1.8.20</serenity.version>
        <serenity.jbehave.version>1.35.0</serenity.jbehave.version>
        <chromedriver-dep.version>77.0.3865.40</chromedriver-dep.version>

SerenityBDD Chrome 首选项 (serenity.properties):

chrome_preferences.profile.default_content_settings.popups=0 
chrome_preferences.download.default_directory=./files/ 
chrome_preferences.download.prompt_for_download=false 
chrome_preferences.download.directory_upgrade=true 
chrome_preferences.pdfjs.disabled=true

我尝试过的其他方法，手动设置 ChromeOptions。

@Step
public CouponSearchActions waitABitAndClickOnExport() {
    pageRefreshAndCheckCouponStatus();
    if (couponViewPage.getCouponStatusIsCreated().isVisible()) {
        setExperimentalChromeOption();
        couponViewPage.getExportCouponButton().clickAndWait();
    }
    return this;
}

private ChromeOptions setExperimentalChromeOption() {
    HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
    chromePrefs.put("profile.default_content_settings.popups", 0);
    chromePrefs.put("download.default_directory", System.getProperty("user.dir"));

    ChromeOptions options = new ChromeOptions();
    options.setExperimentalOption("prefs", chromePrefs);
    return new ChromeOptions();
}

Try to update your chrome and chromedriver.

第一季度 ChromeDriver 无法在“ headless ”模式下下载任何文件。

答:使用 chromedriver 服务

WebDriver driver;
ChromeDriverService driverService = ChromeDriverService.createDefaultService();
try {
    driver = new ChromeDriver(driverService, options);
}catch(Throwable t) {
    APP_LOGS.error(t.getMessage());
    t.printStackTrace();
}
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);


/**** DOWNLOAD HACK ON HEADLESS BROWSERS *****/
Map<String, Object> commandParams = new HashMap<>();
commandParams.put("cmd", "Page.setDownloadBehavior");
Map<String, String> params = new HashMap<>();
params.put("behavior", "allow");
params.put("downloadPath", downloadFilepath);
commandParams.put("params", params);
ObjectMapper objectMapper = new ObjectMapper();
HttpClient httpClient = HttpClientBuilder.create().build();
try {
    String command = objectMapper.writeValueAsString(commandParams);
    String u = driverService.getUrl().toString() + "/session/" + ((RemoteWebDriver)driver).getSessionId() + "/chromium/send_command";
    APP_LOGS.debug(u);
    HttpPost request = new HttpPost(u);
    request.addHeader("content-type", "application/json");
    request.setEntity(new StringEntity(command));
    httpClient.execute(request);
}catch (Exception e) {
    APP_LOGS.debug(e.getMessage());
}

注意:

将 Chrome/ChromeDriver 更新到最新版本。

此问题已在 ChromeDriver 77.0.3865.40 (2019-08-20) 中得到解决。 https://chromedriver.storage.googleapis.com/77.0.3865.40/notes.txt
