  #获取重定向的URI
  #参数1:   url      #业务URL，即最终需要跳转到的url,域名中的主机名称可选，可以写 'www.baidu.com/xxx', 也可以写 '/xxx'。 这里主要用于重定向。
  #参数2:   app_id   #公众账号app_id
  #参数3:   schema_host 当前项目的域名(包含http://)：如http://www.baidu.com
  #可选参数4: state
  #示例：get_snsapi_uri url:'/weixin/service1/ddd?a=1', app_id: 'wx4564afc37fac0ebf', schema_host: "http://lxq.mdcc.com"
