确保已经拥有了该插件。
可以登录人宅学院找到该插件
如果想知道里面的技术实现 ，可以看这个 Bilibili接入技术如何实现
该插件支持三种模式来获取弹幕；
1.账户验证(推荐)
2.直连
3.HTTP获取弹幕
我们也支持发送弹幕到直播间
适合的场景：虚拟人直播，互动游戏，无人直播等
我们介绍一下账户验证获取弹幕，这种方式是极其推荐的，这也是官方主流方式
一.账户验证接入B站直播
首先我们要拿到 key 密钥 appid
1.先登录 哔哩哔哩直播服务中心 点击进入中心，确保已经注册了，如果没有注册，需要注册，一般两三天就可以收到注册成功的信息。
2.接下来需要创建项目
3.填写基础信息 项目名称 随便写一个，项目分类 直播工具，简单简介 图标等
4.创建完成后打开创建的项目，我们需要里面的 项目ID（APP ID）
5.来到这个项目页面，点击个人资料：
6.获取对应的密钥和key
接下来我们拿到code 主播身份码 打开直播姬 点击互动游戏，上面有获取身份码
至此，我们已经拿到了密钥，key, appid, 主播身份码,接下来我们进入UE界面：
7.初始化账户信息 把刚刚获取到的信息填入下面
8.绑定回调代理
9.打开对应的响应：
关于直播API的详细分析分析可以参考这个代码解释 （当前验证方式接入属于 LIVE_OPEN_PLATFORM）：

EmojiImgURL:情绪图标，如果有的话
DMType:详细可以参考这个：
//弹幕类型 0：普通弹幕 1：表情包弹幕
UENUM(BlueprintType)
enum class EBilibiliDaMuType :uint8
{
NORMAL_DAMU = 0 UMETA(DisplayName = "Normal"),//普通弹幕
EMOTICON_DAMU = 1 UMETA(DisplayName = "Emoticon"),//表情包弹幕
};

最后，可以使用Start开始弹幕捕获 用Stop停止弹幕捕获：
验证链接方式，就讲解完毕了。
二.通过HTTP获取弹幕
1.可以通过房间ID直接链接房间，获取弹幕：
2.可以通过JsonStringToSimpleDanMu 获取转换的弹幕信息
3.房间ID获取：
就是这个/14614095? ，/和？中间的那个就是房间ID(RoomID)
至此，HTTP直链的方式我们讲解完毕了。
三.如何发送弹幕
发送弹幕，严格来说不是官方的app，官方也没有讲解如何发送，这里我们通过其他方式来是实现发送弹幕：
首先保证拥有谷歌浏览器，因为我们要获取到几个重要的参数：
1.首先进入浏览器，进入直播间,按F12,进入调试模式，点击红点，发一个弹幕，捕捉了一个send。
2.来到负载这个位置，这里显示了roomid和csrf以及csrf_token，这些我们后面会用到，先记录一下。
3.接下来来到Headers里面，我们需要cookie和user-agent这两个数据，复制一下，后面用到。
4.接下来我们进入UE里面，构建如下的信息：
5.发送弹幕到直播间
6.这个对应发送到直播间后，对应的回调：
7.记得绑定代理：
至此，我们的发送弹幕也完结了。
