python - 如何提交具有 1 个以上提交按钮的表单。向网站发送 POST。 (Python)

Question

我正在使用 Python Mechanize 创建脚本可以登录网站并提交表格。
但是，此表单有 3 个提交按钮(预览、发布和取消)。我习惯了只有一个按钮...

这是表格:

<TextControl(subject=Is this good for the holidays? Anyone know about the new tech?)>
  <IgnoreControl(threads=<None>)>
  <TextareaControl(message=Im new to technology stocks.)>
  <SelectControl(identity=[*annamae41g])>
  <RadioControl(E=[5, 4, *3, 2, 1, 0])>
  <SubmitControl(SubmitPreview=Preview Message) (readonly)>
  <SubmitControl(SubmitPost=Post Message) (readonly)>
  <SubmitControl(SubmitCancel=Cancel) (readonly)>
  <HiddenControl(action_btn=) (readonly)>
  <HiddenControl(_charset_=) (readonly)>
  <HiddenControl(.crumb=4DxnFEwMIGG) (readonly)>
  <HiddenControl(r=/Stocks_(A_to_Z)/Stocks_G) (readonly)>
  <HiddenControl(bn=25263) (readonly)>
  <HiddenControl(<None>=annamae41g) (readonly)>>

这是我的代码:

br.open(newtopic_url)
br.select_form(name="postmsg")
br.form['subject'] = "Is this good for the holidays? Anyone know about the new tech?"
br.form['message'] = "Im new to technology stocks."
br.form['E'] = ['3']
br.form['identity'] = ['annamae41g']
print br.form
br.submit()

如果我运行这个脚本......它不会工作。没发生什么事。我假设因为它在表单中有 3 个提交按钮？或者这是另一个问题？

Answer 1

我和你有同样的问题。

一个有两个提交按钮的表单，第一个是预览，第二个是提交。

起初， Mechanize 只使用第一个按钮，我可以看到服务器回答使用

response = browser.submit()
print response.read()

我将提交按钮名称作为参数提交给 Mechanize 提交功能，它起作用了!

response = browser.submit("submit")

测试一下，它应该也适合你!
