后台显示正确，一级菜单正常，二级出不来

test.java运行输出的menu：

{"button":[{"name":"menu11","sub_button":[{"name":"test21","sub_button":[],"type":"view","url":"http://soul.ngrok.natapp.cn/weixin/pages/test.jsp"},{"name":"test22","sub_button":[],"type":"view","url":"http://soul.ngrok.natapp.cn/weixin/pages/test.jsp"}],"type":"click"},{"key":"12","name":"test12","sub_button":[],"type":"scancode_push"},{"key":"13","name":"test13","sub_button":[],"type":"location_select"}]}

test运行通过但是手机上二级菜单一直出不来
