微软自动化神器【Playwright】（四）之 浏览器操作

写在前面

我的国庆七天

该做点什么

Playwright之浏览器操作

基础参数

1、创建浏览器对象

//默认为无头浏览器方式启动
browser = playwright.chromium().launch();
//参数设定方式启动
browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(true).setSlowMo(5000));

2、创建浏览器上下文

context = browser.newContext();

3、创建Page对象

page = context.newPage();

浏览操作

1、浏览器最大化

 Playwright playwright = Playwright.create();
        //看到某博主写的python版的加--start-maximized这个参数，本人尝试后发现无效(Mac系统)
        //Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions()
        //        .setArgs(Collections.singletonList("--start-maximized"))
        //        .setHeadless(false));
        Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));
        browser.newContext(new Browser.NewContextOptions()
                .setIgnoreHTTPSErrors(true)
                .setJavaScriptEnabled(true)
                .setViewportSize(2880, 1800));
        Page page = browser.newPage();
        page.navigate("https://www.cnblogs.com/longronglang");
        System.out.println(page.title());
        browser.close();
        playwright.close();

2、多个浏览器启动

import com.microsoft.playwright.*;
import org.testng.annotations.Test;

/**
 * @author rongrong
 * @version 1.0
 * @description 浏览器窗口操作
 * @date 2022/10/7 2:21 PM
 */
public class TestBrowser {


    /**
     * 创建浏览器上下文
     *
     * @param browser
     * @return
     */
    public BrowserContext createContext(Browser browser) {
        BrowserContext context = browser.newContext(new Browser.NewContextOptions()
                .setIgnoreHTTPSErrors(true)
                .setJavaScriptEnabled(true)
                //此处可以理解为设定指定窗口启动
                .setViewportSize(1980, 1080));
        return context;
    }


    /**
     * 创建浏览器
     *
     * @param name
     * @param playwright
     * @return
     */
    public Browser createBrowser(String name, Playwright playwright) {
        try {
            switch (name) {
                case "firefox":
                    return playwright.firefox().launch(new BrowserType.LaunchOptions().setHeadless(false).setTimeout(120 * 1000));
                case "chromium":
                    return playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false).setTimeout(120 * 1000));
                case "webkit":
                    return playwright.webkit().launch();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }


    @Test
    public void testBrowser() {
        //火狐浏览器
        startBrowser("firefox");
        //谷歌浏览器
        startBrowser("chromium");
        //这个浏览器不好使
        //startBrowser("webkit");
    }

    /**
     * 根据浏览器类型，启动浏览器
     *
     * @param browserName
     */
    private void startBrowser(String browserName) {
        //创建Playwright
        Playwright playwright = Playwright.create();
        //创建Browser（使用谷歌浏览器）
        Browser browser = createBrowser(browserName, playwright);
        //创建浏览器上下文
        BrowserContext browserContext = createContext(browser);
        Page page = browserContext.newPage();
        page.navigate("https://www.cnblogs.com/longronglang");
        System.out.println("page.title :" + page.title());
        System.out.println(browserName + " 浏览器启动了！");
        browser.close();
        browserContext.close();
        playwright.close();
    }
}

3、前进/后退/刷新操作

        Playwright playwright = Playwright.create();
        Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));
        browser.newContext(new Browser.NewContextOptions()
                .setIgnoreHTTPSErrors(true)
                .setJavaScriptEnabled(true)
                .setViewportSize(2880, 1800));
        Page page = browser.newPage();
        page.navigate("https://www.cnblogs.com/longronglang");
        //输出：久曲健 - 博客园
        System.out.println("page title:"+page.title());
        //这里是运行时打断点使用，方便调试（适用于喜欢用录制回放生成脚本的同学）
        //page.pause();
        pause(3);
        //打开百度页面
        page.navigate("https://www.baidu.com/");
        //输出：百度一下，你就知道
        System.out.println("page title:"+page.title());
        //后退操作
        page.goBack();
        pause(3);
        //输出：久曲健 - 博客园
        System.out.println("page title:"+page.title());
        //前进操作
        page.goForward();
        pause(3);
        System.out.println("page title:"+page.title());
        //刷新操作
        page.reload();
        pause(3);
        //输出当前url
        System.out.println("page url:"+page.url());
        browser.close();
        playwright.close();
