How to connect to the Java backend with WeChat applet

Front-end time someone asked me how to connect to the background of the mini program, so I directly posted the code here

In

// api request
 request(url, params) {
  return new Promise((resolve, reject) => {
   ({
    url: baseUrl + url,
    method: 'POST',
    data: params,
    success(res) {
     ()
     resolve()
    },
    fail(res) {
     (res)
     reject(res)
    }
   })
  })
 },
 
 // api
 getHomeLayout(params) {
  return ('/wechat/home/getHomeLayout', params)
 },

Here baseUrl is the name of your native ip + your background project

Go to the page where you need to call the API, and instantiate the var app = getApp(); use app. getHomeLayout and pass in the specified parameters.
