Question

我尝试使用Python的mechanize模块自动登录网站。以下是登录form代码：

    <TD><B>Site:</B></TD>
    <TD><SELECT name="site" class="drpdwn" size=1 width="200" onChange="populateZones(this, '');"><OPTION value="">Select a site</OPTION></SELECT>
    <INPUT type="hidden" name="shortsite" size="3" value=""></TD>
</TR>
<TR>
    <TD><B>Zone:</B></TD>
    <TD><SELECT name="zone" class="drpdwn" size=1 width="100"><OPTION value="">Select a zone</OPTION></SELECT></TD>
</TR>
<TR>
    <TD><B>User ID:</B></TD>
    <TD><INPUT type="text" name="user" size=20 value=""></TD>
</TR>
<TR>
    <TD><B>Password:</B></TD>
    <TD><INPUT type="password" name="password" size=20></TD>
</TR>
<TR>
    <TD>&nbsp;</TD>
    <TD><INPUT name="submit1" type="submit" value="Log On" style="color: #003399; font-weight: bold; font-size: 10pt">
    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<input name="reset1" type="reset" value="Reset" style="color: #003399; font-weight: bold; font-size: 10pt" onClick="resetform();">
    </TD>

我可以毫不费力地解析和填充user，password和shortsite字段。在填充zone下拉列表时出现问题。从上面的HTML代码中可以明显看出，网页正在使用populateZones javascript函数来填充区域。我正在寻找一种方法来强制存储在配置文件中的区域值。我过去使用HTML::Form::ForceValue做了类似的事情。在python中是否有任何等价物？

以下是我正在努力自动登录的python脚本的摘录： br['user'] = self.config['COMMON.USER'] br['password'] = self.config['COMMON.PASSWORD']

br['user'] = self.config['COMMON.USER']

br['password'] = self.config['COMMON.PASSWORD']

我能够通过使用javascript来实现这一目标。共享代码可能会有所帮助：

br.select_form(predicate=self.__form_with_fields("user", "password"))  
br.form.set_all_readonly(False)  
br['user']           = self.config['COMMON.USER']  
br['password']       = self.config['COMMON.PASSWORD']  
br.form["shortsite"] = self.config['COMMON.SITE'] 

zone1 = br.form.find_control("zone")

#Add drop down list value dynamically like the Javascript does
mechanize.Item(zone1, {"contents": "Hurray","value": "Hurray"})

#Choose the just added option
br.form["zone"] = ["Hurray"]

Perl的Python中的HTML :: Form :: ForceValue等价物
