（如果你不想存在本地，也可以把表情包放在云上）

2.2 放入Vue工程中

将这个emo表情整个文件夹放在vue工程中的src/assets下
在这里插入图片描述

2.3 在Vue工程中定义

这个定义是表情包放在本地的。
如果你的文件不在本地也可以使用，注意要去掉require。

        { title: "[蛋糕]", url: require("../assets/face/dangao.gif") },
        { title: "[发红包]", url: require("../assets/face/fahongbao.gif") },
      ],
    };
  },

这里为什么要在url里面写require呢？
因为平常直接的本地url地址是会被再次编译，如果引用的是向我们这样定义的变量值，是不会被编译的，还是会找不到，所以require相当于代替了编译。

2.5 解析表情（添加时需要）

  //解析表情
      var reg = /\[.+?\]/g;
      this.commentContent = this.commentContent.replace(reg, function (str) {
        for (let i = 0; i < Emoji.data().emojiList.length; i++) {
          // eslint-disable-next-line no-empty
          if (Emoji.data().emojiList[i].title === str) {
            var url = Emoji.data().emojiList[i].url;
          }
        }
