我正在尝试使用从Crawler4J到爬虫的FormAuthInfo身份验证到特定的LinkedIn页面。只有在我正确登录时才能呈现此页面。
这是我的控制器，带有访问 URL：
public class Controller {
public static void main(String[] args) throws Exception {
String crawlStorageFolder = "/data/";
int numberOfCrawlers = 1;
CrawlConfig config = new CrawlConfig();
config.setCrawlStorageFolder(crawlStorageFolder);
PageFetcher pageFetcher = new PageFetcher(config);
RobotstxtConfig robotstxtConfig = new RobotstxtConfig();
RobotstxtServer robotstxtServer = new RobotstxtServer(robotstxtConfig, pageFetcher);
CrawlController controller = new CrawlController(config, pageFetcher, robotstxtServer);
String formUsername = "session_key";
String formPassword = "session_password";
String session_user = "email@email.com";
String session_password = "myPasswordHere";
String urlLogin = "https://www.linkedin.com/uas/login";
AuthInfo formAuthInfo = new FormAuthInfo(session_password, session_user, urlLogin, formUsername, formPassword);
config.addAuthInfo(formAuthInfo);
config.setMaxDepthOfCrawling(0);
controller.addSeed("https://www.linkedin.com/vsearch/f?keywords=java");
controller.start(Crawler.class, numberOfCrawlers);
controller.shutdown();
}
}
这是我的爬网程序类：
public class Crawler extends WebCrawler {
private final static Pattern FILTERS = Pattern.compile(".*(\.(css|js|gif|jpg" + "|png|mp3|mp3|zip|gz))$");
@Override
public boolean shouldVisit(Page referringPage, WebURL url) {
String href = url.getURL().toLowerCase();
return !FILTERS.matcher(href).matches() && href.startsWith("https://www.linkedin.com");
}
@Override
public void visit(Page page) {
String url = page.getWebURL().getURL();
System.out.println("URL: " + url);
if (page.getParseData() instanceof HtmlParseData) {
HtmlParseData htmlParseData = (HtmlParseData) page.getParseData();
String text = htmlParseData.getText();
String html = htmlParseData.getHtml();
System.out.println(html);
Set<WebURL> links = htmlParseData.getOutgoingUrls();
System.out.println("Text length: " + text.length());
System.out.println("Html length: " + html.length());
System.out.println("Number of outgoing links: " + links.size());
}
}
}
当我使用身份验证运行此应用程序时，出现以下错误：

这与我的 http 客户端如何处理 LInkedIn 返回的 cookie 有关吗？
有什么建议吗？ 谢谢！
首先：这不是crawler4j的问题。这是一个LinkedIn问题，根据最新的谷歌条目，他们很长时间没有解决这个问题。
但是，您的方法将不起作用，因为crawler4j尊重爬网程序道德。 如果你看看机器人.txt你会发现，爬虫不会爬任何东西。
