scrapy: Can I extract request formdata from response?

Question

I am using scrapy to scrape some data, I am wondering how much data of Request the Response stores.

My specific question is shown in the following code:

def parse(self,response):
    r = FormRequest(url=url1, formdata={somedata}, callback=parse2)

    #is this line necessary if I want the formdata being attached?
    r.meta['formdata'] = formdata

    yield r

def parse2(self,response):
    #can I access to the formdata here without that line of code?

Any suggestion would be appreciated.

Yes, however formdata is already converted into body and won't be the dictionary but a string as far as I remember.

so try r.body also quick reminder you can check the attributes of an object by: dir(r)
