如何抓取 Indiegogo：众筹数据提取终极指南

from playwright.sync_api import sync_playwright

def scrape_indiegogo_dynamic(url):
    with sync_playwright() as p:
        # 使用干净的上下文启动浏览器
        browser = p.chromium.launch(headless=True)
        page = browser.new_page()
        
        # 导航并等待 React 填充组件
        page.goto(url, wait_until='networkidle')
        
        # 筹款金额的特定选择器
        page.wait_for_selector('.i-project-raise-amount')
        
        results = {
            "title": page.inner_text('h1'),
            "funding": page.inner_text('.i-project-raise-amount'),
            "backers": page.inner_text('.i-project-raise-backers')
        }
        
        print(results)

# 示例用法:
# scrape_indiegogo_dynamic('https://www.indiegogo.com/projects/example-project')

import scrapy
from scrapy_playwright.page import PageMethod

    name = 'indiegogo_spider'

    def start_requests(self):
        # 使用 scrapy-playwright 处理动态内容
        yield scrapy.Request(
            'https://www.indiegogo.com/explore/all',
            meta={
                "playwright": True,
                "playwright_page_methods": [
                    PageMethod("wait_for_selector", ".discoverableCard-base"),
                ],
            }
        )

    def parse(self, response):
        for card in response.css('.discoverableCard-base'):
            yield {
                'name': card.css('.discoverableCard-title::text').get(),
                'raised': card.css('.discoverableCard-formattedAmount::text').get(),
                'url': response.urljoin(card.css('a::attr(href)').get())
            }

const puppeteer = require('puppeteer');
