websocket 点解发送 连接已关闭..._an unrecoverable ioexception occurred so the conne

当我们点击发送消息时，触发onclose 事件

 that.ws.onclose = function(e) {
                    // 关闭 websocket
                    console.log('连接已关闭...');
                    console.log(e.code + e.reason + e.wasClean);
                    //延迟执行重连
                    setTimeout(() => {
                        that.creatSocket();
                    }, that.$global.delay);
                };

输出：连接已关闭…
1002 An unrecoverable IOException occurred so the connection was closed true

解决方案：

   this.messageInfo.message = this.message;
            // this.messageInfo.user_id = this.userInfo.userId;
            this.messageInfo.orgId = getCookie('setOrgId');

            var message = JSON.stringify(this.messageInfo);
            console.log('message==socket', message);
            that.ws.send(message);

检查send方法里面的参数，例如：
上面的代码的报错原因是将参数user_id注释了
