问题


When using driver.get on a certain website (driver.get("http://steamcommunity.com/market/search?appid=730")), I get this error:

It works fine with other urls, and it also worked with this one until I enabled javascript by putting true in WebDriver driver = new HtmlUnitDriver(true);. I needed to do this because my program wasn't working properly without javascript, and it seems like this steam community market page requires javascript in order to access it, even by just typing in the url. What am I doing wrong?

Using a user agent will solve the ScriptException. Use DesiredCapabilties to do so. See below code:

DesiredCapabilities capabilities = DesiredCapabilities.htmlUnit();
capabilities.setBrowserName("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20160101 Firefox/66.0");

HtmlUnitDriver driver = new HtmlUnitDriver(capabilities);
driver.setJavascriptEnabled(true);

driver.get("http://steamcommunity.com/market/search?appid=730");
System.out.println(driver.getPageSource());

This works fine.

Although, an alternate solution would be to use PhantomJSDriver which I found to be much better at locating elements.

Download PhantomJS.exe file and set the exe's file path as PHANTOMJS_EXECUTABLE_PATH_PROPERTY

public class CopyOfTest1 
{
PhantomJSDriver driver;
WebDriverWait wait;
DesiredCapabilities capabilities;

CopyOfTest1()
{
    //set binary path of phantomJS driver
    capabilities = new DesiredCapabilities();       
    capabilities.setJavascriptEnabled(true);
    capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "drivers/phantomjs.exe");
    capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_PAGE_SETTINGS_PREFIX,"Y");
    capabilities.setCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:16.0) Gecko/20121026 Firefox/16.0");

    //intialize driver and set capabilties
    driver = new PhantomJSDriver(capabilities);
    //intitlaize webdriverwait class
    wait = new WebDriverWait(driver, 30);
}

void start()
{
    driver.get("http://steamcommunity.com/market/search?appid=730");
    System.out.println(driver.getPageSource());
    driver.quit();
}

public static void main(String[] args) throws Exception
{
    new CopyOfTest1().start();
}
}

You are missing double quotation " in url. Try the following

driver.get("http://steamcommunity.com/market/search?appid=730")
