Public method util
Before you start to
ch2-2branchcode/directory import tool for the development of micro-channel
In this chapter, we will create a new file in three util directory, these files are provided a number of commonly used functions, variables, then we have to use in different pages
├── utils/
│ ├─ config.js
│ ├─ index.js
│ ├─ mock.jsStep 1. config.js configuration constants
The file is stored some const constants (such as the development environment, the default copy, default pictures, etc.), there will be a core object of these constants, and finally through the export default corecore of this object will be exported. Since only store some configuration constants, not repeat it here:
'use strict';
const env = 'dev';// dev production
/*
* 默认接口出错弹窗文案
* @type {string}
*/
const defaultAlertMessage = '好像哪里出了小问题~ 请再试一次~';
/*
* 默认分享文案
* @type {{en: string}}
*/
const defaultShareText = {
en: 'iKcamp英语-学英语口语听力四六级'
};
/*
* 小程序默认标题栏文字
* @type {string}
*/
const defaultBarTitle = {
en: 'iKcamp英语学习'
};
/*
* 文章默认图片
* @type {string}
*/
const defaultImg = {
articleImg: 'https://n1image.hjfile.cn/mh/2017/06/07/7e8f7b63dba6fa3849b628c0ce2c2a46.png',

};
let core = {
env: env,
defaultBarTitle: defaultBarTitle['en'],
defaultImg: defaultImg,
defaultAlertMsg: defaultAlertMessage,
defaultShareText: defaultShareText['en'],
isDev: env === 'dev',
isProduction: env === 'production'
};
export default core;Step 2. mock.js data
This file is used to store some false data to facilitate local development and debugging, if you have a mock server, of course, better

}Step 3. document main inlet increases index.js
index.js File, we will increase the number of public function method, such as a request for network packages, log log under development environment, local storage, etc.
First of all, we have the configuration information config.jsand false data mock.jsimported to and exported to normal
'use strict'
import Promise from '../lib/promise'
import config from './config'
import * as Mock from './mock'
let util = {
}
export default utilThe second line of code:
import Promise from '../lib/promise'This role is to introduce a piece of code to achieve Promise of third-party tool library , so that we can use the method in the applet Promise to solve 回调地狱the problem.
Note: In the new version of the applet has supported native Promise method
Here we begin to expand util package object public methods:
increasing the log console debugging features
If the environment for the dev environment, the print parameters content
let util = {
isDEV: config.isDev,
log(){
this.isDEV && console.log(...arguments)
}
}Package alert popup
Because the development environment, often need to look at some object information, so increasing the object type resolution
let util = {
// 此处省略部分代码
alert(title = '提示', content = config.defaultAlertMsg) {
if ('object' === typeof content){
content = this.isDEV && JSON.stringify(content) || config.defaultAlertMsg
}
wx.showModal({
title: title,
content: content
})
}
}wx.showModal api method is micro-channel official of the specific usage can consult the documentation
Local cache data reading function of the package
wx.getStorage document address
wx.setStorage document address
let util = {
// 此处省略部分代码
getStorageData(key, cb) {
let self = this;
// 将数据存储在本地缓存中指定的 key 中，会覆盖掉原来该 key 对应的内容，这是一个异步接口
wx.getStorage({
key: key,
success (res) {
cb && cb(res.data);
},
fail (err) {
let msg = err.errMsg || '';
if( /getStorage:fail/.test(msg) ) {
self.setStorageData(key)
}
}
})
},
setStorageData(key, value = '', cb) {
wx.setStorage({
key: key,
data: value,
success() {
cb && cb();
}
})
}
}Next, we will encapsulate network requests, and increase local
mockfunction
