Python:机械化无法找到所有表单输入

Question

我需要填写name=“电子邮件”，但机械化说name=“电子邮件”不存在(查看输出)。为什么我找不到它？我必须接受另一个命令吗？或者我可以通过替换html文件中的一些文本来解决这个问题？

  <input class="box410" type="text" VCARD_NAME="vCard.Email" id="email" name="email" value="" tabindex="17" placeholder="Kontakt E-Mail Adresse" />

代码：

import mechanize

reg = "https://reg.webmail.freenet.de/freenet/Registration"
browser = mechanize.Browser()
browser.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]
browser.open(reg)
browser.select_form(nr = 0)
browser.form['localpart'] = "hansp3056" #Wunschname
browser.click(type="image", nr=0) #Weiter
browser.submit().read()
browser.select_form(nr = 0)
print [form for form in browser.forms()][0]

输出：

您应该首先选择要使用的表单，然后通过id指定元素。在您提到的网页中，它被称为localpart。以下是示例代码：

import mechanize

br = mechanize.Browser()
response = br.open("https://reg.webmail.freenet.de/freenet/Registration")

# Check response here
# :
# :

form = -1
count = 0
for frm in br.forms():  
    if str(frm.attrs["id"])=="regForm":
        form = count
        break

    count += 1

# Check if form is not -1
# :
# :

br.select_form(nr=form)

或者，如果您知道只有一种表单，则可以简单地执行br.select_form(nr=0)

然后，最后：

br.form["localpart"] = "test@test.com"
