Selenium 4でAjax通信のレスポンスを確認する例(Java)

2022/02/04に公開

Selenium 4からChromeDevTools経由でAjax通信内容をキャプチャすることが出来ます。

maven

org.seleniumhq.selenium:selenium-chrome-driver:4.1.1
org.seleniumhq.selenium:selenium-devtools-v96:4.1.1
org.seleniumhq.selenium:selenium-java:4.1.1
org.seleniumhq.selenium:selenium-support:4.1.1

ローカルのChromeDriverを利用する場合の例

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.devtools.DevTools;
import org.openqa.selenium.devtools.HasDevTools;
import org.openqa.selenium.devtools.v96.network.Network;
import org.openqa.selenium.remote.Augmenter;
import java.net.MalformedURLException;
import java.util.Optional;

public class TestMain {
    public static void main(String[] args) throws MalformedURLException {
        System.setProperty("webdriver.chrome.driver", "chromedriver.exe");
        WebDriver driver =  new ChromeDriver();
        driver = new Augmenter().augment(driver);
        DevTools devTools = ((HasDevTools) driver).getDevTools();
        devTools.createSession();
        devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty()));
        devTools.addListener(Network.responseReceived(),
                entry -> {
                    System.out.println("Request Id:"+entry.getRequestId() + "\t" + entry.getResponse().getUrl());
                    Network.GetResponseBodyResponse res = devTools.send(Network.getResponseBody(entry.getRequestId()));
                    System.out.println(res.getBody());
                });
        driver.get("https://github.com/");
        driver.quit();
    }
}

Selenium DockerなどGridサーバを経由する場合の例

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.devtools.DevTools;
import org.openqa.selenium.devtools.HasDevTools;
import org.openqa.selenium.devtools.v96.network.Network;
import org.openqa.selenium.remote.Augmenter;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.openqa.selenium.remote.RemoteWebDriver;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Optional;
public class Main {
    public static void main(String[] args) throws MalformedURLException {
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setBrowserName("chrome");
        WebDriver driver =  new RemoteWebDriver(new URL("http://192.168.24.42:4444/wd/hub"), caps);
        driver = new Augmenter().augment(driver);
        DevTools devTools = ((HasDevTools) driver).getDevTools();
        devTools.createSession();
        devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty()));
        devTools.addListener(Network.responseReceived(),
                entry -> {
                    System.out.println("Request Id:"+entry.getRequestId() + "\t" + entry.getResponse().getUrl());
                    Network.GetResponseBodyResponse res = devTools.send(Network.getResponseBody(entry.getRequestId()));
                    System.out.println(res.getBody());
                });
        driver.get("https://github.com/");
        driver.quit();
    }
}
