承接微信小程序开发。扫码加微信。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：
varrecorder=wx.getRecorderManager();constoptions={duration:10000,//指定录音的时长，单位mssampleRate: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/mp3frameSize: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(){varthat=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：
viewclass='new_txt_ai'viewclass='arrow'em/emspan/span/viewviewclass='ai_content'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/view/view.new_txt_ai{width:460rpx;border-radius:7rpx;left:20rpx;background-color:#fff;position:relative;border:1pxsolid#d0d0d0;float:left;}.new_txt_ai.arrow{position:relative;width:40rpx;left:-30rpx;}.new_txt_ai.arrowem{position:absolute;border-style:solid;border-width:15rpx;top:20rpx;border-color:transparent#d0d0d0transparenttransparent;}.new_txt_ai.arrowspan{position:absolute;top:20rpx;border-style:solid;border-width:15rpx;border-color:transparent#ffftransparenttransparent;left:2rpx;}.ai_content{word-break:break-all;padding:17rpx30rpx17rpx30rpx;}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。聊天室实现效果图：
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。js源码
