第二篇-用Flutter手撸一个抖音国内版，看看有多炫
前言
继上一篇使用Flutter开发的抖音国际版后再次撸一个国内版抖音，大部分功能已完成，主要是Flutter开发APP速度很爽, 先看下图
项目主要结构介绍
这次主要的改动在api.dart 及douyin.dart里，国内抖音的api是不同的，另外地址以及实体类也不一样。详细下面介绍.
抖音的实体类
主要是讲json转化为实体模型，然后绑定到view 层面，写这个实体类还是很耗费时间的，毕竟得先用爬网知识讲抖音的json拿到，并且根据json反向写实体类.
这个地址获取到抖音的推荐列表json： https://creator.douyin.com/aweme/v1/creator/data/billboard/?billboard_type=4，绑定第一个Douyin实体，拿到所有抖音的url地址
通过第二个api地址 https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids= 拿到抖音视频所有的json信息并且绑定VideoData实体类

取抖音无水印视频，这里才是关键
通过这个api地址 https://aweme.snssdk.com/aweme/v1/play/?video_id={}&ratio=720p&line=0&media_type=4&vr_type=0&improve_bitrate=0&is_play_url=1&h265=1&adapt720=1 可以成功的拿到无水印视频,
此方法仅用于学习研究目的，不得从事违法活动哈, 否则与本作者无关.
具体实现代码如下
import 'dart:io';
import 'package:flutter/cupertino.dart';
import 'package:http/http.dart' as http;
import 'package:dio/dio.dart';
class RequestController {
//static String host = "https://www.tiktok.com/";
static String host = "https://creator.douyin.com";
String url = host + "/aweme/v1/creator/data/billboard/?billboard_type=4";
String video =
"https://www.iesdouyin.com/web/api/v2/aweme/iteminfo/?item_ids=";
String player = "https://aweme.snssdk.com/aweme/v1/play/?video_id=";
Future<String> getVideos() async {
try {
var response = await http.get(url);
return response.body;
} catch (e) {
return e.toString();
}
}
//获取无水印的视频
Future<String> getRedirects(String videoid) async {
try {
var response = await new Dio().get(
player +
videoid +
"&ratio=720p&line=0&media_type=4&vr_type=0&improve_bitrate=0&is_play_url=1&h265=1&adapt720=1",
options: Options(
headers: headers,
contentType: "text/html; charset=utf-8",
followRedirects: false,
validateStatus: (status) {
return status < 500;
}),
);
if (response.statusCode == 302) {
return response.data.toString().split('"')[1];
}
return '';
} catch (ex) {
return '';
}
}
Future<String> getCookie() async {
try {
var response = await http.get(host + "/share/item/");
return response.headers["set-cookie"];
} catch (e) {
return "error";
}
}
var headers = {
"user-agent":
"Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1"
};
}
剩下就是改造TrendingScreen里获取视频的方法
getTrending() async {
//var cookies = await api.getCookie();
//api.setCookie(cookies);
try {
var response = await http.get(
api.url,
headers: api.headers,
);
Douyin tiktok = Douyin.fromJson(jsonDecode(response.body));
tiktok.billboardData.forEach(
(item) {
setState(() {
getVideos(item);
});
},
);
} catch (ex) {
SimpleDialog(
title: Text('Hot videos list is empty'),
);
print(ex);
}
}
把获取到的无水印视频加载到view层
getVideos(BillboardData v) async {
try {
var url = v.link.split("/")[5];
var response = await http.get(
api.video + url + "&dytk",
headers: api.headers,
);
VideoData videoData = VideoData.fromJson(jsonDecode(response.body));
//获取无水印的视频地址
api.getRedirects(videoData.itemList[0].video.playaddr.uri).then((url) => {
print( Uri.decodeFull(url)),
if (url != '')
{
videos.add(VideoItem(
data: videoData,
videourl: url,
))
}
});
} catch (ex) {
print(ex);
}
}
最后，就是绑定视频数据啦，大功告成！
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: <Widget>[
DouyinVideoPlayer(
url: videourl,
),
title(),
VideoDescription(
description: data.itemList[0].textExtras[0].hashtagName,
musicName: data.itemList[0].music.title,
authorName: data.itemList[0].music.author,
userName: data.itemList[0].author.nickname,
),
ActionsToolbar(
comments: data.itemList[0].statistics.commentCount.toString(),
userImg: data.itemList[0].author.avatarMedium.urlList[0],
favorite: data.itemList[0].statistics.diggCount,
coverImg: data.itemList[0].music.covermedium.urlList[0],
),
],
),
);
}
结语
写到这里，手撸一个抖音app完成了基本功能，一些数据转化比喻点赞数还是原始int数据，需要转化成K M 等，后续待完善，毕竟花了一天时间来写这个app纯粹为了兴趣. 本人也极喜欢玩抖音.
另外因为写得匆忙，只测试了少量数据，json返回的数据有些为null ，也不知道具体是啥类型，这个待完善。 各位博友们觉得感兴趣的点个赞哈. 支持支持!
顺便说一下，各位支持的话点赞关注我继续完善剩余的部分，有需要学习了解的可以联系我，代码上传到github ，地址：https://github.com/WangCharlie/douyin，到这里就点个star, 谢谢.
