java代码

public void loginBaidu(){        try {        WebClient webClient = new WebClient();        HtmlPage htmlPage = webClient.getPage("https://www.baidu.com/");        System.out.println(htmlPage.asXml());        HtmlAnchor loginAnchor = (HtmlAnchor) htmlPage.getElementByName("tj_login");        System.out.println(loginAnchor.asXml());                HtmlPage loginPage = loginAnchor.click();        System.out.println(loginPage.asXml());                HtmlTextInput userNameInput = (HtmlTextInput) loginPage.getElementById("TANGRAM__PSP_8__userName");        userNameInput.click();        userNameInput.setValueAttribute("loginName");        HtmlPasswordInput pwdInput = (HtmlPasswordInput) loginPage.getElementById("TANGRAM__PSP_8__password");        pwdInput.click();        pwdInput.setValueAttribute("password");                HtmlSubmitInput submitInput = (HtmlSubmitInput) loginPage.getElementById("TANGRAM__PSP_8__submit");        HtmlPage loginAfterPage = submitInput.click();        System.out.println(loginAfterPage.asXml());                HtmlPage suPage = loginAfterPage.getElementById("su").click();        System.out.println(suPage.asXml());        } catch (Exception e) {            e.printStackTrace();        }    }

实现了简单的登录功能，后面的其他功能可以自己发挥一下
