Wechat small program WebSocket to send text, pictures, voice and WebSocket common problem solutions

Common problems with applets WebSocket :(solved in this article) 1. Automatically disconnects and reconnects, but only two Websockets exist. –1 Compatibility: 1.1 Normal Chat After a period of time, the WebSocket is automatically disconnected and reconnected, and the previous chat records are saved

–1 Compatibility: 1.2 If the user has a black screen but does not exit the small program after a period of time, WebSocket automatically disconnects and re-links, and saves the previous chat records

–1 Compatibility: 1.3 In the chat room page, click the back button in the upper right corner, the page will automatically execute the uninstallation, this time the WebSocket is not destroyed, the second entry will exist two WebSockets, the third entry will be an error (can exist two websockets at the same time).

Solution: Because there are many compatibility situations, the solution can be seen in the code. The idea is to add a switch that automatically reconnects. (You can create a WebSocket only after the WebSocket is destroyed.) Determine whether to reconnect the WebSocket.

2. The recording succeeds, but the backend cannot receive the voice file. Wx.arraybuffertobase64 (res.frameBuffer), convert the resulting arrayBuffer to Base64 and pass it to the back end, setting signType: ‘BASE64.

3. The BASE64 decoding fails when recording is transmitted to the back-end. Solution: Confirm with the back end whether the sampling rate, encoding rate, audio format, and frame size of the recording file are consistent.

Recommended Settings:

    var recorder = wx.getRecorderManager();
    const options = {
      duration: 10000.// Specifies the recording duration, in ms
      sampleRate: 16000./ / sampling rate
      numberOfChannels: 1.// Number of recording channels
      encodeBitRate: 24000.// Code rate
      format: 'mp3'.// Audio format, valid value aAC /mp3
      frameSize: 12.// Specify the frame size, in KB
    }
    recorder.start(options) // Start recording
Copy the code

4. How to automatically focus the page on the latest chat messages

Solution: Perform a public page focus method after the list assignment of the chat message is successful:

  // Public focus method, the method is clumsy, but the transition effect is smooth and smooth
  bottom: function() {
    var that = this;
    this.setData({
      scrollTop: 100000})},// Call an example:
      this.setData({
        allContentList: that.data.allContentList,
      })
      this.bottom();
Copy the code

5. When the user enters a space and sends it, the chat bubble will definitely distort because it is not as tall as the space line.

Solution: The CSS sets the minimum height of the bubble box —- min-height: 80rpx; (The value can be customized according to requirements)

6. How to implement the small triangle of chat bubble box? The triangle also wants to give it a border, how to do that?

Effect:

Implementation steps: set the style of text bubble box – in the text bubble box set a new box relative positioning, put an EM and a SPAN label inside, set absolute positioning, use the border to set transparent color, example code:

<view class='new_txt_ai'>
  <view class='arrow'>
     <em></em>
     <span></span>
  </view>
  <view class='ai_content'>121 is a natural number between 120 and 122. It is also odd number, composite number, square number</view>
</view>
Copy the code

.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;
}

All the relevant code, the code logic is more clear but strong plasticity. Provide reference.
