wx 小程序JS 写法出问题自己优化

wx.onSocketError(error => {
    console.error('socket error:', error)
})

}; Hlclient.prototype.send = function (msg) { wx.sendSocketMessage({ data: msg }) }

Hlclient.prototype.regAction = function (func_name, func) { if (typeof func_name !== 'string') { throw new Error("an func_name must be string"); } if (typeof func !== 'function') { throw new Error("must be function"); } console.log("register func_name: " + func_name); this.handlers[func_name] = func; return true

}

//收到消息后这里处理， Hlclient.prototype.handlerRequest = function (requestJson) { var _this = this; try { var result = JSON.parse(requestJson) } catch (error) { console.log("catch error", requestJson); result = transjson(requestJson) }
