摘要
小红书的图片如果是长按保存是有水印的,如何获得无水印的图片?当然是通过网页解析!
代码
from flask import Flask, request, jsonify import requests import re app = Flask(__name__) @app.route('/') def index(): url = request.args.get('url') if url: result = get_image_urls(url) return jsonify(result) else: return jsonify({'error': 'Missing URL parameter'}) def get_html(url): headers = { "authority": "www.xiaohongshu.com", "cache-control": "max-age=0", "sec-ch-ua": '"Chromium";v="21", " Not;A Brand";v="99"', "sec-ch-ua-mobile": "?0", "sec-ch-ua-platform": '"Windows"', "upgrade-insecure-requests": "1", "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36", "accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9", "sec-fetch-site": "same-origin", "sec-fetch-mode": "navigate", "sec-fetch-user": "?1", "sec-fetch-dest": "document", "accept-language": "zh-CN,zh;q=0.9", } response = requests.get(url, headers=headers) return response.text def json_content(html): rule = r"<script>window\.__INITIAL_STATE__=(.*?)</script>" js = re.search(rule, html, re.I) if js: content = js.group(1) return content else: return None def get_image_urls(url): html = get_html(url) js = json_content(html) js = js.replace(r"\u002F", r"/") all_urls = re.findall(r'url":"(http://[^\":\{\}\[\]]*?wm_1)"', js) return {'image_urls': all_urls} if __name__ == "__main__": app.run(debug=True)
使用 Python的Flask框架实现一个简单的HTTP服务器,然后通过?url=小红书链接,就可以解析出小红书无水印的图片地址。
演示
http://127.0.0.1:5000/?url=http://xhslink.com/wZh4pw
PHP版
<?php function get_html($url) { $headers = array( "authority" => "www.xiaohongshu.com", "cache-control" => "max-age=0", "sec-ch-ua" => '"Chromium";v="21", " Not;A Brand";v="99"', "sec-ch-ua-mobile" => "?0", "sec-ch-ua-platform" => '"Windows"', "upgrade-insecure-requests" => "1", "user-agent" => "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36", "accept" => "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9", "sec-fetch-site" => "same-origin", "sec-fetch-mode" => "navigate", "sec-fetch-user" => "?1", "sec-fetch-dest" => "document", "accept-language" => "zh-CN,zh;q=0.9", ); $options = array( 'http' => array( 'header' => implode("\r\n", array_map( function ($v, $k) { return $k . ':' . $v; }, $headers,
