在 Java 中使用带有 Cookie 的 XML-RPC

Question

我正在尝试使用 XML-RPC 从网站加载数据。到目前为止，这种方法效果很好，但不适用于需要登录的页面。我为此发送了我的用户名和密码。 我从同事那里知道cookies也是需要的。即 PHPSESSID 和另一个，我们称之为 OTHER_COOKIE ；） 我从浏览器中提取这些。

但是，我已经两天无法实际使用这些cookie了。我找不到让 XmlRpcClient 获取这些 cookie 的方法。我总是得到的答案是我无权访问这些页面。可能有像 XmlRpcTransport 或类似的类应该用于此目的，但我无法进一步了解。文档情况很糟糕。

这是至少适用于不需要登录的页面的代码。

（如果它起作用：我正在尝试阅读的页面是“MoinMoinWiki”。）

    private final XmlRpcClient client;

    public MoinMoinWikiClient(String baseUrl, String username, String password) throws Exception {



        String endpointUrl = baseUrl + "/moinmoin/?action=xmlrpc2";

/*
 EDIT: I now realise that using a username and password here is insane. That's exactly what cookies are for. I only need them for a manual login to create the cookies. Sorry, that was a bit stupid of me
*/
        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl() {
            @Override
            public String getBasicUserName() {
                return username;
            }

            @Override
            public String getBasicPassword() {
                return password;
            }
        };

        config.setServerURL(new URL(endpointUrl));

        this.client = new XmlRpcClient();
        client.setConfig(config);

        String examplePageName = "any_page";

        HashMap<String, Object> result = (HashMap<String, Object>)client.execute("getPageInfo", new Object[]{examplePageName});

        info("Initialized XML-RPC client with URL: " + xmlRpcEndpoint);

    }

我已经研究了两天的解决方案和文档。我问了ChatGPI很长时间，很详细;)

无数假设的解决方案都以类未知且无法添加到 Maven 的事实告终。例如CookieManager、CookiesStore ...

public MoinMoinWikiClient(String wikiUrl, String username, String password) throws Exception {
        String endpointUrl = wikiUrl + "/moinmoin/?action=xmlrpc2";

/*
 EDIT: I now realise that using a username and password here is insane. That's exactly what cookies are for. I only need them for a manual login to create the cookies. Sorry, that was a bit stupid of me
*/
        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl() {
            @Override
            public String getBasicUserName() {
                return username;
            }

            @Override
            public String getBasicPassword() {
                return password;
            }
        };

        config.setServerURL(new URL(endpointUrl));

        BasicCookieStore cookieStore = new BasicCookieStore();
        List<Cookie> cookies = new ArrayList<>();
        cookies.add(new org.apache.http.impl.cookie.BasicClientCookie("PHPSESSID", Main.PHPSESSID));
        cookies.add(new org.apache.http.impl.cookie.BasicClientCookie("OTHER_COOKIE", Main.OTHER_COOKIE));
        cookieStore.addCookies(cookies.toArray(new Cookie[0]));

        CloseableHttpClient httpClient = HttpClients.custom()
                .setDefaultCookieStore(cookieStore)
                .build();


        this.client = new XmlRpcClient();
        client.setConfig(config);
    }

我终于成功了...！ 这是代码：

import java.net.MalformedURLException;
import java.net.URL;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class XmlRpcManager {
    private String domain;
    private List<Cookie> cookies;

    public XmlRpcManager(String domain) {
        this.domain = domain;
        this.cookies = new ArrayList<>();

        cookies.add(new Cookie(".xxx.de", "PHPSESSID", Config.PHPSESSID, "/", null, true));
        cookies.add(new Cookie(".xxx.de", "XXXX_COOKIENAME", Config.XXXX_COOKIENAME, "/", null, true));

    }


    public List<String> getAllPages(String filter) {

        String xmlRpcUrl = "https://xxxxxx/moinmoin/?action=xmlrpc2";

        HttpClient httpClient = new HttpClient();
httpClient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);

        if (cookies != null) {
            for (Cookie cookie : cookies) {
                httpClient.getState().addCookie(new org.apache.commons.httpclient.Cookie(
                        cookie.getDomain(),
                        cookie.getName(),
                        cookie.getValue(),
                        cookie.getPath(),
                        cookie.getExpiryDate(),
                        cookie.getSecure()

            }
        }

        XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();

        try {
            config.setServerURL(new URL(xmlRpcUrl));
        } catch (MalformedURLException e) {
            System.err.println("bad url format >> " + xmlRpcUrl);
            throw new RuntimeException(e);
        }

        XmlRpcClient client = new XmlRpcClient();
        XmlRpcCommonsTransportFactory factory = new XmlRpcCommonsTransportFactory(client);
        factory.setHttpClient(httpClient);
        client.setTransportFactory(factory);
        client.setConfig(config);

        Object result = null;
        try {
            result = client.execute("getAllPages", new Object[]{});
        } catch (XmlRpcException e) {
            System.err.println("failed");
            throw new RuntimeException(e);
        }

        Object[] pagesArray = (Object[]) result;


        List<String> pageNames = Arrays.stream(pagesArray)
                .map(Object::toString)
                .filter(s -> filter.isEmpty() || s.contains(filter))
                .collect(Collectors.toList());

        System.out.println("Found: " + String.valueOf(pageNames.size()));

        return pageNames;
    }
}
