业务流程个人信息：用户上传短视频。源码：https://github.com/limingios/wxProgram.git 中wx-springboot 和 No.15
用户选择视频（10秒限制），也可以通过摄像头拍摄
打开选择背景音乐。
可以选择音乐或者不选择输入视频的描述。
controller 上传视频
保存视频的截图
用户是否选择背景音乐
7.1 是：直接保存视频
7.2 否：合并视频和背景音乐，保存视频
官方介绍：https://developers.weixin.qq.com/miniprogram/dev/api/media-video.html#wxchoosevideoobject
代码修改
> 可以获取到通过微信的组件获取到视频的长度，宽度，高度，视频的截图，视频的临时路径，时长。然后针对这些可以判断出来是否允许上传。

})增加选择背景音乐的界面
用户可以选择视频，接下来我们选择北京音乐的界面。用户选择音乐，或者用户可以不选择音乐直接提交不选择音乐直接提交。官方界面：https://developers.weixin.qq.com/miniprogram/dev/component/audio.html

})后端开发后端接口在一个服务器上，后端的web在一台服务器上。后端的web上传小程序，需要同步到后端接口所在的一个服务器上。我们选择zokeeper。后边会讲
service中添加
BgmService.java
package com.idig8.service; import java.util.List; import com.idig8.pojo.Bgm; public interface BgmService { public ListqueryBgmList(); }
BgmServiceImpl.java
package com.idig8.service.Impl; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Propagation; import org.springframework.transaction.annotation.Transactional; import com.idig8.mapper.BgmMapper; import com.idig8.pojo.Bgm; import com.idig8.service.BgmService; @Service public class BgmServiceImpl implements BgmService { @Autowired private BgmMapper bgmMapper; @Transactional(propagation =Propagation.SUPPORTS) @Override public ListqueryBgmList(){ return bgmMapper.selectAll(); } }
BgmController.java
package com.idig8.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.idig8.service.BgmService;
import com.idig8.utils.JSONResult;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
@RestController
@Api(value="背景音乐接口",tags={"背景音乐接口的controller"})
@RequestMapping(value = "/bgm")
public class BgmController extends BasicController{
@Autowired
private BgmService bgmService;
@ApiOperation(value="获取所有背景音乐",notes="通过获取所有背景音乐")
@PostMapping("/list")
public JSONResult list() {
return JSONResult.ok(bgmService.queryBgmList());
}
}接口已经在swagger验证通过。
小程序开发环境中会报net::ERR_INSUFFICIENT_RESOURCES这个错误，在真机中，不会出现该错误，忽略即可。
PS：通过个人页面传递视频信息，到开发新界面背景音乐和描述，最后到文件信息上传到后台功能已经开发完毕。
