第一行是我自己转换好的post 请求格式
{"template_id":"2","ext_json":{"extAppid":"wx43*********","ext":{"templet":"3","vip":"1"},
"tabBar":{"list":{"pagePath":"pages/index/index","text":"商城","iconPath":"images/food_nor.png",
"selectedIconPath":"images/food_sel.png"}}},"user_version":"hh1.0","user_desc":"test8"}

第二行是微信返回的错误码
{"errcode":47001,"errmsg":"data format error hint: [Mb63Wa08591513]"}
