python - Mechanize 引发 BrowserStateError

Question

我有以下代码:

br = mechanize.Browser()
br._factory.is_html = True
br.form = mechanize._form.ParseString('<form method="post"</form>', 'http://localhost/post.php')[1]

br.form.new_control('text', 'test',{'value':'something'})
br.form.fixup()
br.submit()

该代码有时会起作用，但有时会引发 BrowserStateError:未查看 HTML。我没有正确覆盖 _factory.is_html 吗？

Answer 1

显然，mechanize要求您有实际回复才能提交表单:

def viewing_html(self):
    """Return whether the current response contains HTML data."""
    if self._response is None:
        raise BrowserStateError("not viewing any document")
    return self._factory.is_html
