个人信息:用户上传短视频。
业务流程
- 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
微信插件
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
- 新建页面

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 {
/**
* 获取所有的Bgm列表
* @return
*/
public List<Bgm> queryBgmList();
}
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 List<Bgm> queryBgmList(){
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。
