This article mainly introduces the relevant knowledge of "using es6-promise.js to encapsulate requests and handling asynchronous processes in WeChat Mini Programs". The editor shows you the operation process through practical cases. The operation method is simple, fast and practical. I hope this article "how to use es6-promise.js to encapsulate requests and handle asynchronous processes in WeChat Mini Programs" can help you solve the problem.

WeChat Mini Programs es6-promise.js encapsulates requests and handles asynchronous processes

Download es6-promise.js under the libs folder in the root directory

Create a new httpsPromisify.js under the root directory utils folder, that is, define the method to encapsulate the request

Var Promise = require ('.. / libs/es6-promise.min') function httpsPromisify (fn) {return function (obj = {}) {return new Promise ((resolve, reject) = > {obj.success = function (res) {resolve (res)} obj.fail = function (res) {reject (res)} fn (obj)}} module.exports = {httpsPromisify: httpsPromisify}

Call method:

Var Promisify = require ('.. /.. / utils/httpsPromisify') Page ({onLoad: function () {Promisify.httpsPromisify (wx.request) ({url: "https://XXXXXXX", header: {" Content-Type ":" application/x-www-form-urlencoded "}, method:" POST ", data: {}) .then (function (res) {console.log (res)})} })

Note:

At present, there are many third-party libraries that support promise, such as $q.jsdbluebird.js, etc., but it's important to note that these libraries work well on Wechat development tools, but have no effect on real machines.
