背景：寫了一個爬蟲程序使用的docker部署叛薯，部署后在docker中安裝PhantomJS 比較麻煩瑞佩，于是想到了再另一個docker容器中部署一個PhantomJS 旱爆，通過遠程調(diào)用的方式來使用它
1.啟動一個PhantomJS docker實例
[root@Ieat1 ~]# docker run -d --restart=always --name phantomjs -p 8910:8910 wernight/phantomjs phantomjs --webdriver=8910
2.通過程序遠程調(diào)用
通過Java 調(diào)用:
WebDriver driver = new RemoteWebDriver(
new URL("http://127.0.0.1:8910"),
DesiredCapabilities.phantomjs());
通過python調(diào)用响疚，先運行 pip install selenium安裝selenium
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
driver = webdriver.Remote(
command_executor='http://127.0.0.1:8910',
desired_capabilities=DesiredCapabilities.PHANTOMJS)
driver.get('http://example.com')
driver.find_element_by_css_selector('a[title="hello"]').click()
driver.quit()
3.完整的代碼段：
public class RemotePhantomjsTest {
public static void main(String[] args) throws InterruptedException {
DesiredCapabilities dc = new DesiredCapabilities();
dc.setCapability("phantomjs.page.settings.userAgent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36");
WebDriver webDriver = null;
try {
webDriver = new RemoteWebDriver(new URL("http://127.0.0.1:8910"), dc);
} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
webDriver.get("https://www.baidu.com/");
WebElement webElement = webDriver.findElement(By.xpath("/html"));
String content = webElement.getAttribute("outerHTML");
System.out.println(content);
} catch (Exception e) {
e.printStackTrace();
} finally {
webDriver.close();
}
}
}
監(jiān)控一下docker的日志,發(fā)現(xiàn)調(diào)用成功
[root@Ieat1 ~]# docker logs -f phantomjs
