How to scrape multiple pages with an unchanging URL - Python 3

Question

I recently got in touch with web scraping and tried to web scrape various pages. For now, I am trying to scrape the following site - http://www.pizzahut.com.cn/StoreList

Answer 1

Steps to get the data:

Open the developer tools in your browser (for Google Chrome it's Ctrl+Shift+I). Now, go to the XHR tab which is located inside the Network tab.

After doing that, click on the next page button. You'll see the following file.

Click on that file. In the General block, you'll see these 2 things that we need.

Scrolling down, in the Form Data tab, you can see the 3 variables as

Here, you can see that changing the value of pageIndex will give all the pages required.

Now, that we've got all the required data, we can write a POST method for the URL http://www.pizzahut.com.cn/StoreList/Index using the above data.

Code:

I'll show you the code to scrape first 2 pages, you can scrape any number of pages you want by changing the range().

for page_no in range(1, 3):
    data = {
        'pageIndex': page_no,
        'pageSize': 10,
        'keyword': '输入餐厅地址或餐厅名称'
    }
    page = requests.post('http://www.pizzahut.com.cn/StoreList/Index', data=data)
    soup = BeautifulSoup(page.text, 'html.parser')

    print('PAGE', page_no)
    for row in soup.find_all('div',class_='re_RNew'):
        name = row.find('p',class_='re_NameNew').string
        info = row.find('input').get('value')
        location = info.split('|')
        location_data = location[0].split(',')
        longitude = location_data[0]
        latitude = location_data[1]
        print(longitude, latitude)

Output:
