二、公众号直播对接

1、用户观看端集成

接口文档：https://open.talk-fun.com/docs/js/index.html

1.1、获取用户access_token

用户要观看直播，必须获取对应的用户access_token，通过access_token 获取观看的直播课程；

接口参数：直播id，用户id

（1）创建LiveCourseApiController

        JSONObject object = liveCourseService.getPlayAuth(id, AuthContextHolder.getUserId());
        return Result.ok(object);
    }

}

（2）LiveCourseService添加方法

1
JSONObject getPlayAuth(Long id, Long userId);

（3）LiveCourseServiceImpl实现方法

    UserInfo userInfo = userInfoFeignClient.getById(userId);
    HashMap<Object,Object> options = new HashMap<Object, Object>();
    String res = mtCloudClient.courseAccess(liveCourse.getCourseId().toString(), userId.toString(), userInfo.getNickName(), MTCloud.ROLE_USER, 80*80*80, options);
    CommonResult<JSONObject> commonResult = JSON.parseObject(res, CommonResult.class);
    if(Integer.parseInt(commonResult.getCode()) == MTCloud.CODE_SUCCESS) {
        JSONObject object = commonResult.getData();
        System.out.println("access::"+object.getString("access_token"));
        return object;
    } else {
        throw new GgktException(20001,"获取失败");
    }
}
1.2、下载前端SDK

下载地址：https://open.talk-fun.com/docs/js/download.html

1.3、使用快捷模板

下载模板，修改token获取方式

var url  = window.location.search
var token = url.split("=")[1]
1.4、与前端项目结合

（1）创建直播播放页面 live.html

观众在直播详情页面点击观看，获取通过接口获取access_token，然后带上access_token参数跳转到直播观看页面即可，关键代码：

liveInfo.vue

1
2
3
4
5
6
7
play() {
  api.getPlayAuth(this.liveCourseId).then(response => {
    console.log(response.data);
    window.location = './live.html?token='+response.data.access_token;
    this.finished = true;
  });
},

http://localhost:8080/live.html为直播观看访问方式

1.5、补充接口

（1）LiveCourseApiController类

1

5

@ApiOperation("根据ID查询课程")
@GetMapping("getInfo/{courseId}")
public Result getInfo(
    @ApiParam(value = "课程ID", required = true)
    @PathVariable Long courseId){
    Map<String, Object> map = liveCourseService.getInfoById(courseId);
    return Result.ok(map);
}

（2）LiveCourseServiceImpl实现

@Override
public Map<String, Object> getInfoById(Long id) {
    LiveCourse liveCourse = this.getById(id);
    liveCourse.getParam().put("startTimeString", new DateTime(liveCourse.getStartTime()).toString("yyyy年MM月dd HH:mm"));
    liveCourse.getParam().put("endTimeString", new DateTime(liveCourse.getEndTime()).toString("yyyy年MM月dd HH:mm"));
    Teacher teacher = teacherFeignClient.get(liveCourse.getTeacherId());
    LiveCourseDescription liveCourseDescription = liveCourseDescriptionService.getByLiveCourseId(id);

    Map<String, Object> map = new HashMap<>();
    map.put("liveCourse", liveCourse);
    map.put("liveStatus", this.getLiveStatus(liveCourse));
    map.put("teacher", teacher);
    if(null != liveCourseDescription) {
        map.put("description", liveCourseDescription.getDescription());
    } else {
        map.put("description", "");
    }
    return map;
}

三、微信分享

1、实现目标

1、点播课程详情页面分享

2、微信分享实现方式

参考文档：https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/JS-SDK.html

2.1、绑定域名

先登录微信公众平台进入“设置与开发”，“公众号设置”的“功能设置”里填写“JS接口安全域名”。

说明：本地测试设置内网穿透地址。

image-20220302114513023

2.2、公众号测试号配置

image-20220308125920409

2.3、引入JS文件
1
<script src="http://res.wx.qq.com/open/js/jweixin-1.4.0.js" type="text/javascript"></script>

引入前端项目/public/index.html文件

image-20220308130024856

2.4、封装分享js

参考官方文档封装接口

我们需要分享的页面有直播详情页、点播课程详情页等，因此我们把分享代码封装后，在对应的页面直接引入与调用即可

新建src/util/wxShare.js文件

/**

 */
const wxShare = {
    /**
     * [wxRegister 微信Api初始化]
     * @param  {Function} callback [ready回调函数]
     */
    wxRegister(data,option) { //data是微信配置信息，option是分享的配置内容
        
        wx.config({
            debug: true, // 开启调试模式
            appId: data.appId, // 必填，公众号的唯一标识
            timestamp: data.timestamp, // 必填，生成签名的时间戳
            nonceStr: data.nonceStr, // 必填，生成签名的随机串
            signature: data.signature,// 必填，签名，见附录1
            jsApiList: [
                'onMenuShareAppMessage'
            ] // 必填，需要使用的JS接口列表，所有JS接口列表见附录2
        });
        wx.ready(function(){

            wx.onMenuShareAppMessage({
                title: option.title, // 分享标题
                desc: option.desc, // 分享描述
                link: option.link, // 分享链接
                imgUrl: option.imgUrl, // 分享图标
                success() {
                    // 用户成功分享后执行的回调函数
                    //  option.success()
                    console.log('ok');
                },
                cancel() {
                    // 用户取消分享后执行的回调函数
                    // option.error()
                    console.log('cancel');
                }
            });
        });

        wx.error(function(res){
          // config信息验证失败会执行error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，也可以在返回的res参数中查看，对于SPA可以在这里更新签名。
          //alert('error:'+JSON.stringify(res));
        });
    }
}
export default wxShare
2.5、服务器端接口

新增ShareController类

说明：微信分享要对当前url加密处理，由于我们的url路由都是带“#”符号，服务器端接收不到，因此通过“guiguketan”单词代替了“#”。

    private WxMpService wxMpService;

    @GetMapping("/getSignature")
    public Result getSignature(@RequestParam("url") String url) throws WxErrorException {
        String currentUrl = url.replace("guiguketan", "#");
        WxJsapiSignature jsapiSignature = wxMpService.createJsapiSignature(currentUrl);

        WxJsapiSignatureVo wxJsapiSignatureVo = new WxJsapiSignatureVo();
        BeanUtils.copyProperties(jsapiSignature, wxJsapiSignatureVo);
        wxJsapiSignatureVo.setUserEedId(Base64Util.base64Encode(AuthContextHolder.getUserId()+""));
        return Result.ok(wxJsapiSignatureVo);
    }

}
2.6、点播课程详情分享

页面：courseInfo.vue

（1）引入分享

import wxShare from '@/utils/wxShare'

  let url = window.location.href.replace('#', 'guiguketan')
  shareApi.getSignature(url).then(response => {
    console.log(response.data);
    //记录分享用户
    let link = '';
    if(window.location.href.indexOf('?') != -1) {
      link = window.location.href + '&recommend=' + response.data.userEedId;
    } else {
      link = window.location.href + '?recommend=' + response.data.userEedId;
    }
    let option = {
      'title': this.courseVo.title,
      'desc': this.description,
      'link': link,
      'imgUrl': this.courseVo.cover
    }
    wxShare.wxRegister(response.data, option);
  });
}
2.7、测试

（1）使用手机测试，其他端测试可能会出现错误问题
