This article mainly introduces "how to encapsulate requests and handle asynchronous processes in es6-promise.js in WeChat Mini Programs". In daily operation, it is believed that many people have doubts about how to encapsulate requests and handle asynchronous processes in es6-promise.js in WeChat Mini Programs. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful to answer the question of "how to encapsulate requests and handle asynchronous processes in es6-promise.js in WeChat Mini Programs"! Next, please follow the editor to study!

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.jsdybluebird.js, etc., but it should be noted that these can be used normally on Wechat development tools, but there is no effect on the real machine; so with es6-Promise.js, this personal test is perfect, and the file size is much smaller than the others, so it is recommended that you use it.

At this point, the study on "how to encapsulate requests and handle asynchronous processes in es6-promise.js in WeChat Mini Programs" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
