Python爬虫入门-爬取煎蛋网妹子图

妹子图.JPG

运行环境：Python3.6.0

所需的包：

from bs4 import BeautifulSoup
import requests
import os

伪装：

headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36"
}

目录下新建文件夹：

folder = "ooxx"
os.mkdir(folder)
os.chdir(folder)

网址分析：

urls = ["http://jandan.net/ooxx/page-{}#comments".format(str(i)) for i in range(90, 100)]
# 爬取的页面可更改

主要代码：

for url in urls:
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.text, "lxml")
    images = soup.select("img")
    for image in images:
        image_url = "http:" + image.get("src")
        # 获取图片地址
        filename = image_url.split("/")[-1]
        # 图片命名
        with open(filename, "wb") as f:
            img = requests.get(image_url)
            # 读取图片
            f.write(img.content)
            # 写入图片

一共20行不到，初学者自己动手试试（当然我也是初学者）。
