username=我的賬號&password=密碼&j_captcha_response=驗證碼<=_c3EE266FF-4DEF-26DD-E41B-E748E3CE4443_k0FE723EE-CF04-E8CE-51FC-02153309D601&_eventId=submit&s_uuid=84cf259b-fb88-43c8-9af6-2643b9777bae
其中lt值和s_uuid可以在網頁原始碼中找到
驗證碼輸錯后回傳網頁原始碼，其中有
<legend>登錄資訊</legend>
<form id="loginFormEle" class="fm-v clearfix loginCForm" action="/cas/qianbaoLogin?service=http%3A%2F%2Fuser.qianbao666.com%2Fj_spring_cas_security_check" method="post" onsubmit="return validateData();">
<div style="display:none;">
<p id="errorCodeMsg" class="err">驗證碼已過期</p>
</div>
<ul>
<li id="login-name">
<span class="tip" id="usernameTipsLab">手機號/郵箱/用戶名</span>
<label class="tip">
</label>
<input id="username" name="username" class="input_text w270 fl" tabindex="1" onblur="trimTextValue('username');" accesskey="n" type="text" value="https://bbs.csdn.net/topics/123" size="25" autocomplete="false"/>
會顯示驗證碼過期，最后的value=https://bbs.csdn.net/topics/ 為輸入的手機號
我成功獲取了lt和s_uuid
用xmlhttp發送post請求，，但是始終無法成功登陸 ,回傳原始碼也并沒有告訴我原因, value=https://bbs.csdn.net/topics/也為空
求解啊!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
