如何将视频通过接口上传到抖音平台 java

一、引入相关maven

二、根据小红书文章链接爬取文章内容和图片

三、根据图片、文字、音频等生成视频文件

1、生成视频工具类

2、上传视频到抖音

一、引入相关maven

  1.         <!-- Jsoup 解析HTML文本 -->
  2.         <dependency>
  3.             <groupId>org.jsoup</groupId>
  4.             <artifactId>jsoup</artifactId>
  5.             <version>1.11.3</version>
  6.         </dependency>
  7.         <dependency>
  8.             <groupId>org.apache.commons</groupId>
  9.             <artifactId>commons-lang3</artifactId>
  10.             <version>3.4</version>
  11.         </dependency>
  12.         <!-- 主要用JavaCV来处理视频生成 -->
  13.         <dependency>
  14.             <groupId>org.bytedeco</groupId>
  15.             <artifactId>javacv-platform</artifactId>
  16.             <version>1.5.2</version>
  17.         </dependency>

二、根据小红书文章链接爬取文章内容和图片

JsonResp 是项目里公共的接口返回类型 这里可以直接忽略

videoPath 为视频生成后的地址

该方法可实现图片+文字+音频合成视频

可自定义文本颜色、音频开始位置、图片切换间隔、不同图片尺寸默认上下左右居中不变形

2、上传视频到抖音

具体参考 https://open.douyin.com 抖音开放平台

主要对接以下功能：

1、账号授权：https://open.douyin.com/platform/doc/6848834666171009035   获取授权码

2、上传视频：https://open.douyin.com/platform/doc/6848798087398295555   获取video_id 下一步创建视频会用到

3、创建视频：https://open.douyin.com/platform/doc/6848798087398328323   创建成功会返回抖音视频id item_id 

其他的接口如查询已发布的视频列表 删除视频等可自行查看抖音相关文档
