1.本地安裝phantomjs，並且將bin加入環境變數path中

2.新建java專案，selenium和phantomjs的maven如下，driver有很多種，比如chromedriver等等，phtomjs作為無頭瀏覽器做動態爬蟲專案挺爽的

<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.下面是測試，這裡要設定userAgent，否則有的網頁無法識別你是何種瀏覽器，我這裡直接用的是49版本谷歌，也可以寫你自己的

PhantomJSDriver driver = null;
try {
    //設定必要引數
DesiredCapabilities dcaps = new 
 
DesiredCapabilities();
//ssl證書支援
dcaps.setCapability("acceptSslCerts", true);
//截圖支援
dcaps.setCapability("takesScreenshot", true);
//設定頭
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搜尋支援
 
dcaps.setCapability("cssSelectorsEnabled", true);
//js支援
dcaps.setJavascriptEnabled(true);
//驅動支援
dcaps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY, "C:\\Users\\fdd\\Desktop\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
//建立無介面瀏覽器物件
driver = new PhantomJSDriver(dcaps);
driver.get("https://h5.m.taobao.com/?sprefer=sypc00");
    int size = 100;
    for (int i = 0; i <= size; i++) {
        ((JavascriptExecutor) driver).executeScript("window.scrollBy(0, 100);");//觸發下拉重新整理
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();//關閉瀏覽器
driver.quit();//注意呼叫 不quit會有多個driver程序
}

效果如下
