Uploading files in Java, Selenium using ChromeDriver mode and bezgons

As it is still not clear to me how to download files using --headless mode in ChromeDriver - selenium [Java], please add here an example of how to do it, I am trying to do it like this (file upload works correctly without option " Headless" ):

ChromeOptions lChromeOptions = new ChromeOptions();
HashMap<String, Object> lChromePrefs = new HashMap<String, Object>();
lChromePrefs.put("profile.default_content_settings.popups", 0);
lChromePrefs.put("download.default_directory", _PATH_TO_DOWNLOAD_DIR);
lChromePrefs.put("browser.set_download_behavior", "{ behavior: 'allow' , downloadPath: '"+_PATH_TO_DOWNLOAD_DIR+"'}");

lChromeOptions.addArguments("--headless");
lChromeOptions.addArguments("--disable-gpu");
lChromeOptions.setExperimentalOption("prefs", lChromePrefs);
WebDriver lWebDriver = new ChromeDriver(lChromeOptions);

From what I know downloading files in headless mode should be possible with Chrome v60 + by installing Browser.setDownloadBehaviour(true, _DIRECTORY)

, but I can't seem to find information on whether ChromeDriver supports it or is just using the wrong chrome preferences as arguments

ChromeDriver version: 2.34 Selenium + WebDriver version: 3.8.1

In Java, use like this:



System.setProperty("webdriver.chrome.driver", "/usr/local/bin/chromedriver");
         ChromeOptions options = new ChromeOptions();
                options.addArguments("--test-type");
                options.addArguments("--headless");
                options.addArguments("--disable-extensions"); //to disable browser extension popup

                ChromeDriverService driverService = ChromeDriverService.createDefaultService();
                ChromeDriver driver = new ChromeDriver(driverService, options);

                Map<String, Object> commandParams = new HashMap<>();
                commandParams.put("cmd", "Page.setDownloadBehavior");
                Map<String, String> params = new HashMap<>();
                params.put("behavior", "allow");
                params.put("downloadPath", "//home//vaibhav//Desktop");
                commandParams.put("params", params);
                ObjectMapper objectMapper = new ObjectMapper();
                HttpClient httpClient = HttpClientBuilder.create().build();
                String command = objectMapper.writeValueAsString(commandParams);
                String u = driverService.getUrl().toString() + "/session/" + driver.getSessionId() + "/chromium/send_command";
                HttpPost request = new HttpPost(u);
                request.addHeader("content-type", "application/json");
                request.setEntity(new StringEntity(command));
                httpClient.execute(request);
        driver.get("http://www.seleniumhq.org/download/");
        driver.findElement(By.linkText("32 bit Windows IE")).click();

Hi I tried to implement the solution mentioned by @Vaibhav Sharma above but it didn't work for me. Even when I tried to do the exact same thing he did, that is, download selenium, still headless, it didn't work.

The code I tried to download with selenium is the same as above and post it. Please let me know if I have done anything wrong.

package start;

import java.util.HashMap;
import java.util.Map;

import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;
import org.openqa.selenium.By;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeDriverService;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.*;
import com.fasterxml.jackson.databind.ObjectMapper;

public class Test_Download {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    try {
    System.setProperty("webdriver.chrome.driver","C:\\developmenttools\\START\\webdrivers\\chromedriver.exe");

    ChromeOptions options = new ChromeOptions();
    options.addArguments("--test-type");
    options.addArguments("--headless");
    options.addArguments("--disable-extensions"); //to disable browser extension popup

    ChromeDriverService driverService = ChromeDriverService.createDefaultService();
    ChromeDriver driver = new ChromeDriver(driverService, options);

    Map<String, Object> commandParams = new HashMap<>();
    commandParams.put("cmd", "Page.setDownloadBehavior");
    Map<String, String> params = new HashMap<>();
    params.put("behavior", "allow");
    params.put("downloadPath", "//Downloads");
    commandParams.put("params", params);
    ObjectMapper objectMapper = new ObjectMapper();
    HttpClient httpClient = HttpClientBuilder.create().build();
    String command = objectMapper.writeValueAsString(commandParams);
    String u = driverService.getUrl().toString() + "/session/" + ((RemoteWebDriver)driver).getSessionId() + "/chromium/send_command";

    System.out.println("command= "+command);

    HttpPost request = new HttpPost(u);
    request.addHeader("content-type", "application/json");
    request.setEntity(new StringEntity(command));
    httpClient.execute(request);

    Thread.sleep(5000);

    driver.get("http://www.seleniumhq.org/download/");
    driver.findElement(By.linkText("32 bit Windows IE")).click();
    }catch(Exception exception){

    }


    }

    }

I want to download pdf in headless mode prefs.put("plugins.always_open_pdf_externally", true);

, it works fine using prefs.put("plugins.always_open_pdf_externally", true);

but not in headless mode.
