默认已经安装好chromeDrive
1. 导入引用
代码语言:javascript复制 <!-- https://mvnrepository.com/artifact/org.seleniumhq.selenium/selenium-java -->
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>28.0-jre</version>
</dependency>
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>
2. 这里需要创建几个类,后面会用到
代码语言:javascript复制public class ChromiumDriver extends RemoteWebDriver {
public ChromiumDriver(Capabilities capabilities) {
this(new ChromiumDriverCommandExecutor("goog", ChromeDriverService.createDefaultService()), capabilities, ChromeOptions.CAPABILITY);
}
protected ChromiumDriver(CommandExecutor commandExecutor, Capabilities capabilities, String capabilityKey) {
super(commandExecutor, capabilities);
}
/**
* Launches Chrome app specified by id.
*
* @param id Chrome app id.
*/
public void launchApp(String id) {
execute(ChromiumDriverCommand.LAUNCH_APP, ImmutableMap.of("id", id));
}
/**
* Execute a Chrome Devtools Protocol command and get returned result. The
* command and command args should follow
* <a href="https://chromedevtools.github.io/devtools-protocol/">chrome devtools
* protocol domains/commands</a>.
*/
public Map<String, Object> executeCdpCommand(String commandName, Map<String, Object> parameters) {
@SuppressWarnings("unchecked")
Map<String, Object> toReturn = (Map<String, Object>) getExecuteMethod().execute(ChromiumDriverCommand.EXECUTE_CDP_COMMAND,
ImmutableMap.of("cmd", commandName, "params", parameters));
return ImmutableMap.copyOf(toReturn);
}
@Override
public void quit() {
super.quit();
}
}
代码语言:javascript复制final class ChromiumDriverCommand {
private ChromiumDriverCommand() {}
static final String LAUNCH_APP = "launchApp";
static final String GET_NETWORK_CONDITIONS = "getNetworkConditions";
static final String SET_NETWORK_CONDITIONS = "setNetworkConditions";
static final String DELETE_NETWORK_CONDITIONS = "deleteNetworkConditions";
static final String EXECUTE_CDP_COMMAND = "executeCdpCommand";
// Cast Media Router APIs
static final String GET_CAST_SINKS = "getCastSinks";
static final String SET_CAST_SINK_TO_USE = "selectCastSink";
static final String START_CAST_TAB_MIRRORING = "startCastTabMirroring";
static final String GET_CAST_ISSUE_MESSAGE = "getCastIssueMessage";
static final String STOP_CASTING = "stopCasting";
static final String SET_PERMISSION = "setPermission";
}
代码语言:javascript复制public class ChromiumDriverCommandExecutor extends DriverCommandExecutor {
private static Map<String, CommandInfo> buildChromiumCommandMappings(String vendorKeyword) {
String sessionPrefix = "/session/:sessionId/";
String chromiumPrefix = sessionPrefix "chromium";
String vendorPrefix = sessionPrefix vendorKeyword;
HashMap<String, CommandInfo> mappings = new HashMap<>();
mappings.put(ChromiumDriverCommand.LAUNCH_APP,
new CommandInfo(chromiumPrefix "/launch_app", HttpMethod.POST));
String networkConditions = chromiumPrefix "/network_conditions";
mappings.put(ChromiumDriverCommand.GET_NETWORK_CONDITIONS,
new CommandInfo(networkConditions, HttpMethod.GET));
mappings.put(ChromiumDriverCommand.SET_NETWORK_CONDITIONS,
new CommandInfo(networkConditions, HttpMethod.POST));
mappings.put(ChromiumDriverCommand.DELETE_NETWORK_CONDITIONS,
new CommandInfo(networkConditions, HttpMethod.DELETE));
mappings.put( ChromiumDriverCommand.EXECUTE_CDP_COMMAND,
new CommandInfo(vendorPrefix "/cdp/execute", HttpMethod.POST));
// Cast / Media Router APIs
String cast = vendorPrefix "/cast";
mappings.put(ChromiumDriverCommand.GET_CAST_SINKS,
new CommandInfo(cast "/get_sinks", HttpMethod.GET));
mappings.put(ChromiumDriverCommand.SET_CAST_SINK_TO_USE,
new CommandInfo(cast "/set_sink_to_use", HttpMethod.POST));
mappings.put(ChromiumDriverCommand.START_CAST_TAB_MIRRORING,
new CommandInfo(cast "/start_tab_mirroring", HttpMethod.POST));
mappings.put(ChromiumDriverCommand.GET_CAST_ISSUE_MESSAGE,
new CommandInfo(cast "/get_issue_message", HttpMethod.GET));
mappings.put(ChromiumDriverCommand.STOP_CASTING,
new CommandInfo(cast "/stop_casting", HttpMethod.POST));
mappings.put(ChromiumDriverCommand.SET_PERMISSION,
new CommandInfo(sessionPrefix "/permissions", HttpMethod.POST));
return unmodifiableMap(mappings);
}
public ChromiumDriverCommandExecutor(String vendorPrefix, DriverService service) {
super(service, buildChromiumCommandMappings(vendorPrefix));
}
}
3. 开发工具类,获取ChromiumDriver
代码语言:javascript复制public static ChromiumDriver getChromiumDriver() {
// 设置谷歌浏览器驱动,我放在项目的路径下,这个驱动可以帮你打开本地的谷歌浏览器
String driverFilePath = "你的chromedriver路径";
if (!StringUtils.isEmpty(driverFilePath)){
System.setProperty("webdriver.chrome.driver", driverFilePath);
}
// 设置对谷歌浏览器的初始配置 开始
HashMap<String, Object> prefs = new HashMap<String, Object>();
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", prefs);
String[] a = { "enable-automation" };
options.setExperimentalOption("excludeSwitches", a);
options.addArguments("--headless");
options.addArguments("window-size=1920,1080");
String ua="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36";
options.addArguments(String.format("--user-agent=%s", ua));
options.addArguments("--no-sandbox");
options.addArguments("--disable-gpu");
options.addArguments("--disable-dev-shm-usage");
options.setBinary("/usr/bin/google-chrome");
DesiredCapabilities chromeCaps = DesiredCapabilities.chrome();
chromeCaps.setCapability(ChromeOptions.CAPABILITY, options);
//执行cdp命令,修改webdriver的值为undefined
ChromiumDriver driver = new ChromiumDriver(chromeCaps);
HashMap<String, Object> cdpCmd = new HashMap<String, Object>();
cdpCmd.put("source", "Object.defineProperty(navigator, 'webdriver', {get: () => undefined }); ");
driver.executeCdpCommand("Page.addScriptToEvaluateOnNewDocument", cdpCmd);
return driver;
}
4. 开发工具类,获取网页
代码语言:javascript复制 public static String convertHtml(String url) {
ChromiumDriver chromiumDriver = getChromiumDriver();
try {
chromiumDriver.get(url);
Thread.sleep(6000);
return chromiumDriver.getPageSource();
} catch (Exception e) {
e.printStackTrace();
return null;
} finally {
chromiumDriver.quit();
}
}
