Talk is weak, show me the code

教你下载ditto视频app中的好玩视频

1.ditto视频app

重点内容 2.首先是抓包获取app的视频地址 用charles 开启代理:

同一wifi下,手机设置电脑的代理ip:

然后就抓了,这么多抓包工具,随便你用什么工具了,windows可以用findler. 最后获取的数据接口为: ?page=2

3.用网页分析返回的json:

所需的就是这个url了

4.获取url,因为我是ios开发,所以直接上ios代码了

– (void)getDittoVideos {for (int i = 1;i <= 3; i++) {NSString *url = [NSString stringWithFormat:@”http://ditto.short.tv/api/v1/videos?page=%d”,i];AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {NSLog(@”%d\n”,i);NSString *detail = @””;NSArray *videoList = responseObject;for (int j=0;j<videoList.count;j++) {NSString *name = [NSString stringWithFormat:@”%@.%@.mp4#%@”,videoList[j][@”id”],videoList[j][@”title”],videoList[j][@”url”][@”m3u8″]];detail = [NSString stringWithFormat:@”%@\n%@”,detail,name];}NSLog(@”%@”,detail);} failure:^(AFHTTPRequestOperation *operation, NSError *error) {}];}}

5.地址为m3u8,是一种直播的格式,不是mp4格式,所以用常规方法下载是不行的了,下载m3u8可以用ffmpeg下载 ffmpeg下载地址:https://www.ffmpeg.org/ 下载命令:

copy -bsf:a aac_adtstoasc “fileName.mp4”

6.下载为mp4格式(python)

#coding=utf-8import re,urllib2,os(“url.txt”):contents = line.split(‘#’)name = contents[0]url = contents[1]urlTmp = url.split()cmd = “./ffmpeg -i \”%s\” -c copy -bsf:a aac_adtstoasc \”%s\”” % (urlTmp[0],name)os.system(cmd)

7.ok了,视频都下载下来了

，只有流过血的手指才能弹出世间的绝唱。
