# Python如何進行包圖網免費付費素材爬取
## 前言
在數字內容創作領域,素材資源是設計師和開發者的重要生產資料。包圖網作為國內知名的素材平臺,匯集了大量高質量的圖片、模板、視頻等資源。本文將深入探討如何通過Python技術實現對包圖網素材的自動化爬?。ㄗⅲ罕窘坛虄H用于技術研究,實際應用請遵守平臺用戶協議)。

## 一、環境準備與技術選型
### 1.1 基礎工具棧
```python
# 核心依賴庫
import requests # 網絡請求
from bs4 import BeautifulSoup # HTML解析
import selenium # 動態頁面處理
import re # 正則表達式
import json # 數據格式化
通過開發者工具(F12)分析可見:
- 免費素材URL特征:/free/{category}/index.html
- 付費素材URL特征:/vip/{id}.html
<!-- 示例:圖片素材DOM結構 -->
<div class="material-img">
<img data-src="//img.58pic.com/00/00/00/00.jpg" />
<a href="/download.php?id=12345">下載</a>
</div>
def login(username, password):
session = requests.Session()
login_url = "https://ibaotu.com/login"
# 先獲取token
resp = session.get(login_url)
token = re.search('name="_token" value="(.*?)"', resp.text).group(1)
# 構造表單數據
data = {
"_token": token,
"username": username,
"password": password
}
# 提交登錄
session.post(login_url, data=data)
return session
from selenium.webdriver import ChromeOptions
def init_driver():
options = ChromeOptions()
options.add_argument("--headless") # 無頭模式
options.add_argument("user-agent=Mozilla/5.0...")
driver = webdriver.Chrome(options=options)
return driver
def get_material_list(page=1):
url = f"https://ibaotu.com/ajax.php?action=get_material&page={page}"
headers = {
"X-Requested-With": "XMLHttpRequest"
}
response = requests.get(url, headers=headers)
data = response.json()
for item in data['list']:
yield {
"id": item["id"],
"title": item["title"],
"download_url": f"https://ibaotu.com/download.php?id={item['id']}"
}

}
import random
import time
def human_like_action(driver):
# 隨機滾動
scroll_height = random.randint(300, 800)
driver.execute_script(f"window.scrollBy(0, {scroll_height})")
# 隨機停留
time.sleep(random.uniform(0.5, 2.5))
# 鼠標移動軌跡
action = ActionChains(driver)
action.move_by_offset(
random.randint(10, 50),
random.randint(10, 50)
action.perform()
# MongoDB存儲示例
from pymongo import MongoClient
client = MongoClient('mongodb://localhost:27017/')
db = client['material_db']
def save_to_mongo(data):
db.materials.update_one(
{"id": data["id"]},
{"$set": data},
upsert=True
)
def download_file(url, save_path):
with requests.get(url, stream=True) as r:
r.raise_for_status()
with open(save_path, 'wb') as f:
for chunk in r.iter_content(chunk_size=8192):
f.write(chunk)
if __name__ == "__main__":
# 初始化
session = login("your_username", "your_password")
driver = init_driver()
# 爬取流程
for page in range(1, 10):
materials = get_material_list(page)
for material in materials:
download_file(material['download_url'], f"./downloads/{material['id']}.zip")
time.sleep(random.randint(2, 5))
# 清理
driver.quit()
本文詳細介紹了爬取包圖網素材的技術方案,但需要特別強調:商業用途的爬取必須獲得官方授權。技術開發者應當: 1. 尊重平臺的數據權益 2. 控制爬取頻率避免影響服務 3. 將技術用于正途
建議優先考慮平臺提供的官方API和合作方案,共同維護良好的互聯網生態環境。 “`
