微信小程序：封装全局的promise异步调用方法
一：封装
function POST(url, params) {
let promise = new Promise(function (resolve, reject) {
wx.request({
url: url,
data: params,
method: 'POST',
success: function (res) {
resolve(res.data);
}
})
});
return promise
}
二：调用
const network = require('../../utils/util.js')
network.GET(url, params).then((res) => {
//请求成功的操作
console.log(res)
});
