9GAG 内容抓取

运行

修改 app.js:

• pageCount 为每个分类要抓取的页数，超过实际页数时自动停止。
• type 为获取的数据类型。hot、trending、fresh对应最热、上升、最新
• category 数组为要抓取的分类

执行node app.js运行代码或使用pm2守护进程：pm2 start app.js --name '9gag'。

下载完的视频、图片及JSON文件存储在downloads对应目录下，完整日志在logs目录。

程序说明

1、总共52个分类。

2、数据获取

• url：https://9gag.com/v1/group-posts/group/cute/type/hot?c=10
• 说明：cute 为分类。首次获取只需传入 c=10 即为前十条数据。下次请求附带上次请求返回的 nextCursor 参数即可。每次请求返回10条数据。

3、每个资源的属性：

• 唯一标志： id
• 资源描述： titile

4、资源分三种类型，根据images属性下的字段区分

1. image

   • 属性：image460 image700

2. gif

   • 属性：image460 image460sv image460svwm image700
   • 说明：image460sv image460svwm 两个属性下的 hasAudio 字段为0，及为无声，即为GIF

3. video
