这是什么规范？

发现一个 app 的请求都只是一个 url，POST 请求的 body 指定了一些返回的参数，结构，貌似可能背后使用微服务实现的，有人知道这个是什么情况吗？

请求的 body json 是这样的：

[
  {
    "variables": {
      "count": 10,
      "page": 1,
      "params": "device=android&ep=product&src=wishlist&item=5&page=1&user_id=321"
    },
    "operationName": null,
    "query": "query wishlis--此处详见下面这段"
  }
]

query wishlist($page: Int, $count: Int, $params: String){
  wishlist(page: $page, count: $count){

      has_next_page
      total_data
      items {
        id
        name
