1.提示 使用需要安装各种import的包都是很基础的包直接安装即可。 自备梯子 。
切记把userid和cookie改为自己账号的参数 userid就是点击pixiv头像网址后面一串数 cookie是打开排行榜后按F12打开开发者工具然后切换到network(网络)栏刷新页面找到ranking.php文件在里面就能找到cookie信息。
2.严肃警告
本程序仅可用作个人爱好商业用途严禁请自觉遵守君子协定robots.txt不要给网址过大的压力每天以及同一时段的访问量请控制在一定程度内
3.思路 天天有群友找我要涩图库存根本不够哇得想办法弄点。
pixiv的爬取有很多大佬做过了不过我看了一些都是弄得类似于项目一样确实都很厉害但我的需求简单写在一个文件里适合我这种懒蛋。
首先通过RankingCrawler类的get_multi_page_json方法获取榜单的json数据将id添加到collector中。然后通过collector的collect方法遍历每个id用get_artworks_urls方法获取id页面内的所有图片的urls将url添加到downloader中。最后通过downloader的download方法多线程调用同class内的download_image方法同时下载图片。
4.使用方法 一般来说都是直接run就行所有需要修改的参数都在RankingCrawler类的init中看一眼就明白
5.代码如下
