Это код html для второй страницы.

В результате поиска в режиме разработчика это метод post.

Как я могу перейти на следующую страницу?

Answer 1

'ctl00$ContentPlaceHolder1$data_list1$WebPageNavigatorV21$ctl01' : '1' 

этот контроль номер страницы. и он имеет нулевое значение. если вы хотите перейти на страницу 2, чем изменить его на 1.

вы должны сделать его переменной:

for i in range(page_number): 
    .... 
    'ctl00$ContentPlaceHolder1$data_list1$WebPageNavigatorV21$ctl01' : i 
    ....
