对网络请求做一个简单的封装

//封装网络请求方法
const BASE_URL = "http://xxxxxx"
class Request {
  request(url, method, params) {
    return new Promise((resolve, reject) => {
      wx.request({
        url: BASE_URL + url,
        method: method,
        data: params,
        success: function (res) {
          resolve(res)
        },
        fail: function (err) {
          reject(err);
        }
      })
    })
  }
  get(url, params) {
    return this.request(url, 'GET', params)
  }
  post(url, data){
    return this.request(url, 'POST', data)
  }
}
const request = new Request()
export default request

使用代码：

 import request from 'xxxx' 2 request.get() 3 .then(res=>{}) 4 .catch(err=>{})
