我正在尝试制作一个程序来重新发行我从大学图书馆拿来的书,因为我应该把我的书USER-ID
放在表格中并提交,然后做剩下的代码。但我什至无法获取列出我所有书籍的页面,TypeError
当我尝试打印列出我的书籍的页面的内容时,我得到了。
这是整个追溯。
Traceback (most recent call last):
File "C:/Users/User/PycharmProjects/dictionary/reissue.py", line 43, in
<module>
sign_up['txtmemberid'].value = 'user-id'
TypeError: 'NoneType' object is not subscriptable
Process finished with exit code 1
这是我的代码。
url = 'http://xx.yy.zz.abc:defg/opac/html/checkouts'
browser = RoboBrowser(history=False ,parser='lxml')
browser.open(url=url)
sign_up = browser.get_form(action='./memberlogin')
sign_up['txtmemberid'].value = 'user-id'
opens = browser.submit_form(sign_up)
print(opens.parsed)
和表格源代码。
<form name="form" method="POST" action="./memberlogin"
onsubmit="this.onsubmit= function(){return false;}">
<table class="loginTbl" border="1" align="center" cellspacing="3"
cellpadding="3" width="60%">
<input type="hidden" name="hdnrequesttype" value="1">
<thead>
<tr>
<td colspan="3" align="middle" class="loginHead">Login</td>
</tr>
</thead>
<tbody class="loginBody">
<tr>
<td class="loginBodyTd1" nowrap="nowrap">Employee ID</td>
<td class="loginBodyTd2"><input type="text" name="txtmemberid"
id="txtmemberid" value="" class="loginTextBox" size="30" tabindex="1"
maxlength="8"></td>
<td class="loginBodyTd3" rowspan="2"><input type="submit"
class="goclearbutton" value=" Go " tabindex="3"
onblur="javascript:setFocus()"></td>
有什么帮助吗?
