微信小程序运行一段时间就会报这个错，重启之后就好了，我看网上也有在微信论坛里面说这个事的但是没解决方案。。

搞不懂是怎么回事~String code = getAttr("code");

code = code.trim();

if (!MiniProgramsCodeCache.containsKey(code)) {

com.jfinal.weixin.sdk.api.ApiResult sessionKeyResult = WxaUserApi.getSessionKey(code);

MiniProgramsCodeCache.put(code, sessionKeyResult);
