Làm cách nào để loại bỏ trang web này bằng Python và lxml? danh sách trống trả lại

Question

Vì mục đích giáo dục, tôi đang cố gắng cạo this page dần dần bằng Python and lxml, bắt đầu bằng tên phim.

Từ những gì tôi đã đọc cho đến nay từ các tài liệu Python trên lxml và W3Schools trên XPath, mã này nên mang lại cho tôi tất cả tiêu đề phim trong một danh sách:

from lxml import html 
import requests 

page = requests.get('http://www.rottentomatoes.com/browse/dvd-top-rentals/') 
tree = html.fromstring(page.text) 

movies = tree.xpath('//h3[@class="movieTitle"]/text()') 

print movies 

Về cơ bản, nó sẽ cho tôi mỗi phần tử h3 ở bất kỳ đâu trong tài liệu có thuộc tính class có giá trị "movieTitle". Sau khi chạy mã mặc dù, tôi chỉ nhận được một danh sách trống in ra.

Tôi không thể hiểu tại sao.

tôi đã cố gắng một mình, vì vậy tôi chạy:

movies = tree.xpath('//h3[@class]/text()') 

print movies 

Vâng cái này nên trả lại bất kỳ H3 với lớp thuộc tính, nhưng nó sẽ trả về danh sách này thay vì:

['From RT Users Like You!', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '] 

tôi đã cố gắng nhắm vào chuỗi đầu tiên trên danh sách này bằng cách nhắm mục tiêu giá trị lớp của nó ("noSpacing center") và nó trả về chuỗi duy nhất này thành công. Vì vậy, tôi chắc chắn có một cái gì đó mà tôi hiểu lầm về các công trình lxml/XPath. Bất cứ ai có thể chỉ cho tôi theo hướng hữu ích? Cảm ơn trước!

Answer 1

Thông tin trên http://www.rottentomatoes.com/browse/dvd-top-rentals/ không được hiển thị trực tiếp vào trang nhưng được tải từ XMLHttpRequests.

API bạn đang tìm kiếm, có vẻ là:

http://d3biamo577v4eu.cloudfront.net/api/private/v1.0/m/list/find?page=1&limit=30&type=dvd-top-rentals&services=amazon%3Bamazon_prime%3Bflixster%3Bhbo_go%3Bitunes%3Bnetflix_iw%3Bvudu&sortBy=popularity

Và chuỗi truy vấn được lập tùy thuộc vào các bộ lọc lựa chọn.

Vì vậy, bạn phải thực hiện yêu cầu đến điểm cuối đó (thay vì URL bạn đang yêu cầu) và phân tích cú pháp JSON để trích xuất dữ liệu mong muốn.

Bạn nên chơi với biến "page" GET để nhận biến tiếp theo.

Ví dụ với cURL + JQ:

➜ ~ curl -s http://d3biamo577v4eu.cloudfront.net/api/private/v1.0/m/list/find\?page\=1\&limit\=30\&type\=dvd-top-rentals\&services\=amazon%3Bamazon_prime%3Bflixster%3Bhbo_go%3Bitunes%3Bnetflix_iw%3Bvudu\&sortBy\=popularity | jq '.results[].title'

Ví dụ với Python + Các yêu cầu:

import json 
import requests 

URL = "http://d3biamo577v4eu.cloudfront.net/api/private/v1.0/m/list/find?page=2&limit=30&type=dvd-top-rentals&services=amazon%3Bamazon_prime%3Bflixster%3Bhbo_go%3Bitunes%3Bnetflix_iw%3Bvudu&sortBy=popularity"
