Can't get min_position in twitter scraping correctly

I am trying to scrape twitter.
please enter search.twitter.com and put Comorbidity in search form.
I can get first page correctly, I can see when scrolling down for more tweets, the next page can be gotten from min_position param.
But when send request with next page, I can't get correct content.



Here is my some code.



headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36'}

def start_requests(self):
yield Request(url=self.start_urls[0], callback=self.parse_search_page)

def parse_search_page(self, response):
keyword = 'Comorbidity'
search_url = self.search_url.format(keyword=keyword)
yield Request(url=search_url, callback=self.parse_twitter_page, headers=self.headers)

def parse_twitter_page(self, response):
next_page = None
if self.current_page == 0:
posts = response.xpath('//li[@data-item-type="tweet"]').extract()
min_position = re.search('data-min-position="(.*?)"', response.body)
if min_position:
min_position = min_position.group(1)
next_page = self.next_page_url.format(position=min_position.replace('cm+', 'cm%2B').replace('==', '%3D%3D'))
self.current_page = 1
else:
json_data = json.loads(response.body)
min_position = json_data.get('min_position')

if next_page:
yield scrapy.http.Request(
url=self.next_page_url,
callback=self.parse_twitter_page,
headers=self.headers,
)


How can I get correct min_position?

          I think you had a wrong in parse_twitter_page method.



          if next_page:
          yield scrapy.http.Request(
          url=next_page,
          callback=self.parse_twitter_page,
          headers=self.headers,
          )


          It should not be self.next_page_url.
          I changed from self.next_page_url to next_page
          I hope this will works.
