Question

我正在用假歌打破一个网页:

<input name="Submit" type="button" class="btn" value="query"  onclick = "dataQuery();" />

I want to trigger the onclick event in python, how can I do that, thanks

Answer 1

You can use selenium and/or HTMLUnit to control/simulate a web browser.

请注意,如果你只是想去掉一个具体地点,那么就常常更容易在你自己的法典中重述 Java的逻辑。

Answer 2

关于拆解网页,你可能有兴趣。

For submitting a form you can use FormRequest.from_response:

class Spider(BaseSpider):

    name =  my_spider_name 
    start_urls = [ http://www.domain.com/ ]
    allowed_domains = [ domain.com ]
    advertiser =  domain.com 


    def parse(self, response):
        """Parse first page and submit a form on it"""
        ...
        formdata = { input1 :  1234 ,  input2 : 5678} # overriden form data
        yield = FormRequest.from_response(response,  form_name , formdata = formdata, 
                callback = self.parseFormSubmit)
