1.本地安装phantomjs，并且将bin加入环境变量path中
2.新建java项目，selenium和phantomjs的maven如下，driver有很多种，比如chromedriver等等，phtomjs作为无头浏览器做动态爬虫项目挺爽的
<dependency> <groupId>org.seleniumhq.selenium</groupId> <artifactId>selenium-java</artifactId> <version>3.12.0</version></dependency><dependency> <groupId>com.codeborne</groupId> <artifactId>phantomjsdriver</artifactId> <version>1.2.1</version></dependency>
3.下面是测试，这里要设置userAgent，否则有的网页无法识别你是何种浏览器，我这里直接用的是49版本谷歌，也可以写你自己的
PhantomJSDriver driver = null;try {//设置必要参数 DesiredCapabilities dcaps = new DesiredCapabilities(); //ssl证书支持 dcaps.setCapability("acceptSslCerts", true); //截屏支持 dcaps.setCapability("takesScreenshot", true); //设置头 dcaps.setCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36"); //css搜索支持 dcaps.setCapability("cssSelectorsEnabled", true); //js支持 dcaps.setJavascriptEnabled(true); //驱动支持 dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "C:\\Users\\fdd\\Desktop\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe"); //创建无界面浏览器对象 driver = new PhantomJSDriver(dcaps); driver.get("https://h5./?sprefer=sypc00"); int size = 100; for (int i = 0; i <= size; i++) {((JavascriptExecutor) driver).executeScript("window.scrollBy(0, 100);");//触发下拉刷新 Thread.sleep(50); System.out.println(i); }File scrFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("C:\\Users\\fdd\\Desktop\\phantomjs-2.1.1-windows\\bin\\baidu_selenium.png"));} finally {driver.close();//关闭浏览器 driver.quit();//注意调用 不quit会有多个driver进程}
效果如下
