部分代码：

toSend: function (msgType, messageId, msgContent, fileContent, path, duration) {

    let that = this

     let uid = that.data.userId

    let cuid = that.data.currenId

    if (msgType == 'img' || msgType == 'audio'){

      util.common.uploadFile(path, function (res) {

         let msg = '{ "type":"chat", "target":' + uid + ', "from":' + cuid + ',"room_id":1, "msg": { "type":"' + msgType + '", "messageId":"' + messageId + '", "msg":"' + msgContent + '","fileContent":"' + res.data.url + '","path":"' + res.data.url + '","duration":"' + duration + '"}}'

        let msgRecords = { msg: msgContent, filePath: conf.apiImgUrl + res.data.url, msgType: msgType, duration: duration, position: "right" }

        var chatRecords = wx.getStorageSync('chat' + cuid + uid)

        if (chatRecords == "" || chatRecords == undefined) {

              wx.setStorageSync('chat' + cuid + uid, [msgRecords])

        } else {

             if (chatRecords.length >= 100) {

                  chatRecords.splice(0, 1);

            }

            chatRecords.push(msgRecords)

            wx.setStorageSync('chat' + cuid + uid, chatRecords)

        }

        that.setData({

          msg: chatRecords

        })

            that.sendSocketMessage(msg)

      })

    }else{

          let msg = '{ "type":"chat", "target":' + uid + ', "from":' + cuid + ',"room_id":1, "msg": { "type":"' + msgType + '", "messageId":"' + messageId + '", "msg":"' + msgContent + '","fileContent":"' + fileContent + '","path":"' + path + '","duration":"' + duration + '"}}'

          let msgRecords = { msg: msgContent, filePath: path, msgType: msgType, duration: duration, position: "right" }

          var chatRecords = wx.getStorageSync('chat' + cuid + uid)

          if (chatRecords == "" || chatRecords == undefined) {

            wx.setStorageSync('chat' + cuid + uid, [msgRecords])

      } else {

            if (chatRecords.length >= 100) {

                  chatRecords.splice(0, 1);

            }

            chatRecords.push(msgRecords)

            wx.setStorageSync('chat' + cuid + uid, chatRecords)

      }

      // console.log(JSON.parse(chatRecords[8]))

          that.setData({

            msg: chatRecords

          })

          that.sendSocketMessage(msg)

    }

  },

效果图如下
