登录到使用Python

Question

AJAX形式

BTW ...本网站仅与Internet Explorer工程....

我试图取消一个网站的客户端，这样我可以为他们自动执行任务。基本上，它会抓住不同的报告，寻找转身时间，并通过电子邮件发送给客户。我的报废程序工作正常，我遇到的问题是使用Mechanize登录到网站，因为登录表单正在使用AJAX。我有四处寻找解决方案，但似乎无法找到我正在寻找什么。

下面是HTML表单和（从我能告诉的）处理它的AJAX。

 

function TranLogin() { var url = 'login.aspx?isAjax=true&eventTarget=TranLogin'; var postData = Form.serialize('Form1'); ajaxRequest = new Ajax.Request( url, { method : 'post', postBody : postData, onComplete : TransLoginFinished, onFailure : reportError, onException : reportException }); }
 

function TransLoginFinished(serverResponse) { if (requestFailed) return; xmlNodes = serverResponse.responseXML; usrSite = "8000"; usrCode = decodeXmlChar(xmlNodes.getElementsByTagName('UserCode')[0].text); if (xmlNodes.getElementsByTagName('LoginResult')[0].text == '-1'){ alert(decodeXmlChar(xmlNodes.getElementsByTagName('FailMsg')[0].text)); Form.enable('Form1'); return; } if (xmlNodes.getElementsByTagName('LoginResult')[0].text == '20'){ window.location.replace('initpasswd.aspx?usersite=' + usrSite + '&usercode=' + usrCode); return; } if (xmlNodes.getElementsByTagName('LoginResult')[0].text == '14'){ window.location.replace('chgpasswd.aspx?type=chgpwd&usersite=' + usrSite + '&usercode=' + usrCode); return; } if (xmlNodes.getElementsByTagName('LoginResult')[0].text == '16'){ window.location.replace('chgpasswd.aspx?type=pwdexpire&usersite=' + usrSite + '&usercode=' + usrCode); return; } if (xmlNodes.getElementsByTagName('LoginResult')[0].text == '0'){ if (xmlNodes.getElementsByTagName('PwdExpireWarning')[0].text == 'true'){ var changePwdNow = window.confirm(decodeXmlChar(xmlNodes.getElementsByTagName('PwdExpireMsg')[0].text)); if (changePwdNow == true){ window.location.replace('chgpasswd.aspx?type=chgpwd&usersite=' + usrSite + '&usercode=' + usrCode); return; } // var arg = { promptMsg :decodeXmlChar(xmlNodes.getElementsByTagName('PwdExpireMsg')[0].text), // buttons : [ { value : "Yes", rtnVal : 1 }, // { value : "No", rtnVal : 0 } // ] // }; // var rtn = window.showModalDialog('../Modules/ModalMessageBox.aspx',arg, "dialogHeight:140px;dialogWidth:500px; center:1;status:no;"); // if (rtn && rtn == 1){ // window.location.replace('chgpasswd.aspx?type=chgpwd&usersite=' + usrSite + '&usercode=' + usrCode); // return; // }
 } if (JTrim($('txtHospCode').value) == '') { hospList = decodeXmlChar(xmlNodes.getElementsByTagName('HospList')[0].text).split('|'); if (hospList.length < 2) { selectedHospCode = hospList[0].split('-')[0]; TranSelectHosp(selectedHospCode); return; } $('divHospList').style.display = 'block';
 

   for(i=0;i<hospList.length;i++) 
       { 
        if (hospList[i] != '') 
        { 
         divHospCode = document.createElement("div"); 
         divHospCode.className='divHospCode'; 
         $('divHospListBG').appendChild(divHospCode); 
         lnkHospCode = document.createElement("a"); 
         if (hospList[i].length <= 33) 
          lnkHospCode.innerText = hospList[i]; 
         else 
          lnkHospCode.innerText = hospList[i].substr(0,30) + '...'; 
         lnkHospCode.title = hospList[i]; 
         lnkHospCode.className = 'lnkHospCode'; 
         divHospCode.appendChild(lnkHospCode); 
         lnkHospCode.onmouseover = function(){this.style.color = '#000000';} 
         lnkHospCode.onmouseout = function(){this.style.color = '#6c6c6c';} 
         lnkHospCode.onclick = function(){TranSelectHosp(this.innerText.split('-')[0]);} 
         if (i > 7 && $('divHospListBG').style.overflow != 'auto') 
         { 
          $('divHospListBG').style.height = '198px'; 
          $('divHospListBG').style.overflow = 'auto'; 
         } 
        } 
       } 
       return; 
      } 
      else 
      { 
       TranSelectHosp(JTrim($('txtHospCode').value)); 
      } 
     } 
    } 
 

<form name="Form1" method="post" action="login.aspx" id="Form1"> 

输入帐户代码：

  <div class="divRight"> 
       <input name="txtHospCode" type="text" id="txtHospCode" class="inputClass" maxlength="4" /> 
      </div> 
      <div class="divLeft"> 
       <span>Input User Code:</span> 
      </div> 
      <div class="divRight"> 
       <input name="txtUserCode" type="text" id="txtUserCode" class="inputClass" maxlength="6" /> 
      </div> 
      <div class="divLeft"> 
       <span>Input Password:</span></div> 
      <div class="divRight"> 
       <input name="txtPassword" type="password" id="txtPassword" class="inputClass" /> 
      </div> 
      <div class="divLeft"> 
       <span>Login As:</span> 
      </div> 
      <div class="divRight"> 
       &nbsp;<input type="radio" name="rdLoginType" value="D" checked="checked" />Doctor&nbsp;&nbsp; 
       <input type="radio" name="rdLoginType" value="T" />Other 
      </div> 
      <div class="divLeft"> 
      </div> 
      <div class="divRight"> 
       <input class="buttonClass" id="btnOK" type="button" value="Enter" onclick="LoginIn();" /> 
       <input class="buttonClass" id="btnReset" type="button" value="Reset" onclick="ResetInput();" /> 
      </div>

就我所知，机械化并没有处理Javascript。所以你的选择是，我想尝试的粗略顺序：

• 在您的浏览器关闭JavaScript，看看你是否仍然可以登录到网站。如果是这样，请尝试使用该过程进行机械化。
• 尝试找出AJAX窗体的效果（服务器端和客户端），并尝试使用Python来模拟它。如果你还没有找到它，像Firebug这样的东西是非常宝贵的。
• 使用允许Python控制真实浏览器的各种库之一。我从来没有这样做过，但我知道至少有Firefox和IE的包装。
