機械化提高BrowserStateError

Question

我有以下代碼：

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() 

代碼工作有時但有時它提出BrowserStateError：不查看HTML。我是不是正確覆蓋_factory.is_html？

Answer 1

顯然，mechanize需要你有才能的實際響應提交表單：

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
