The best way to inspect HTTP response headers with Selenium

SeleniumAutomation TestingTesting Tools

We can inspect HTTP response headers with Selenium webdriver. To verify the HTTP header, we should get the response from a source. Some of the HTTP response codes are listed below −

  • 5XX − Represents server concerns.

  • 4XX − Represents issues in resource detection.

  • 3XX − Represents response redirection.

  • 2XX − Represents correct ocde.

The HttpURLConnection class is used to obtain the HTTP response code. To have a link to an URL, the method openConnection is used. Then, we have to use the setRequestMethod method and pass HEAD as parameter to it.

The connect method is applied on the object of the HttpURLConnection class. Finally, the method getResponseCode is used to obtain the response code.

Syntax

HttpURLConnection cn=
(HttpURLConnection)new URL("https://www.tutorialspoint.com/index.htm").
.openConnection();
cn.setRequestMethod("HEAD");
cn.connect();
int rs = cn.getResponseCode();

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
public class HttpCodeResponse{
   public static void main(String[] args) throws
   MalformedURLException, IOException {
      System.setProperty("webdriver.chrome.driver",
      "C:\\Users\\ghs6kor\\Desktop\\Java\\chromedriver.exe");
      WebDriver driver = new ChromeDriver();
      driver.get("https://www.tutorialspoint.com/questions/index.php");
      // wait of 8 seconds
      driver.manage().timeouts().implicitlyWait(8, TimeUnit.SECONDS);
      // establish connection with URL
      HttpURLConnection cn=
      (HttpURLConnection)new URL("https://www.tutorialspoint.com/questions/index.php")
      .openConnection();
      // set the HEAD request
      c.setRequestMethod("HEAD");
      // connection initiated
      cn.connect();
      int res = cn.getResponseCode();
      System.out.println("Http response code: " + res);
      driver.close();
   }
}

Output
