小程序 WebSocket 常见问题：（本文已解决的）
1.自动断开链接，重连但是只能存在两个 WebSocket 的问题。
---1兼容情况：1.1 正常聊天过一段时间 WebSocket 自动断开后重新链接，并且保存之前的聊天记录
---1兼容情况：1.2 在用户黑屏但是没退出小程序过一段时间时 WebSocket 自动断开链接后重新链接，并且保存之前的聊天记录
---1兼容情况：1.3 在聊天室的页面，点击右上角返回按钮，页面会自动执行卸载，这个时候 WebSocket 是没有销毁的，再次进入时会同时存在两个WebSocket，第三次进入就会报错了（只能同时存在两个 WebSocket ）。
解决方案：因为需要兼容的情况比较多，解决方案可详见代码。具体思路就是，添加一个自动重连的开关。（必须WebSocket 销毁以后才能新建WebSocket ）根据情况判断是否重连 WebSocket 。
2. 录音成功，但是发送给后端接收不到语音文件。
解决办法：在已录制完指定帧大小的事件回调函数中， 使用 wx.arrayBufferToBase64(res.frameBuffer)，把得到的arrayBuffer 转为 Base64 再传给后端，同时设置 signType: 'BASE64'。
3.录音传输给后端时，后端BASE64 解码失败的问题。
解决方案：与后端确认 录音文件的采样率、编码码率、音频格式、帧大小是否一致。
推荐设置：
var recorder = wx.getRecorderManager();
const options = {
duration: 10000, //指定录音的时长，单位 ms
sampleRate: 16000, //采样率
numberOfChannels: 1, //录音通道数
encodeBitRate: 24000, //编码码率
format: 'mp3', //音频格式，有效值 aac/mp3
frameSize: 12, //指定帧大小，单位 KB
}
recorder.start(options) //开始录音4.如何自动把页面聚焦在最新的聊天信息
效果图：
解决方案：在聊天信息的list 赋值成功后执行一次公共页面聚焦的方法：
// 公共聚焦方法，方法比较笨，但是过度效果平滑流畅
bottom: function() {
var that = this;
this.setData({
scrollTop: 100000
})
},
//调用示例：
this.setData({
allContentList: that.data.allContentList,
})
this.bottom();5.用户输入空格并发送，这个时候聊天冒泡框样式肯定会变形，因为没有空格行高。
解决方案： css 设置冒泡框最低高度 ---- min-height: 80rpx;（数值根据需求自定义）
6.聊天冒泡框的小三角形怎么实现？三角形还想要给它边框，又如何实现？
效果图：
实现步骤：设置文字冒泡框的样式-在文字冒泡框内新建一个盒子设置相对定位，里面放一个em和一个span标签，设置绝对定位，利用边框设置透明色，示例代码：
121(一百二十一)是 120与122之间的一个自然数。它也是奇数、合数、平方数
.new_txt_ai {
width: 460rpx;
border-radius: 7rpx;
left: 20rpx;
background-color: #fff;
position: relative;
border: 1px solid #d0d0d0;
float: left;
}
.new_txt_ai .arrow {
position: relative;
width: 40rpx;
left: -30rpx;
}
.new_txt_ai .arrow em {
position: absolute;
border-style: solid;
border-width: 15rpx;
top: 20rpx;
border-color: transparent #d0d0d0 transparent transparent;
}
.new_txt_ai .arrow span {
position: absolute;
top: 20rpx;
border-style: solid;
border-width: 15rpx;
border-color: transparent #fff transparent transparent;
left: 2rpx;
}
.ai_content {
word-break: break-all;
padding: 17rpx 30rpx 17rpx 30rpx;
}还有很多常见问题就不多啰嗦了，直接上代码吧。因业务原因，发送图片和录音功能的代码暂时注释，注释打开可用。

全部相关代码，代码逻辑比较多但是思路清晰，可塑性较强。提供借鉴参考。
