Hello 小程序
1. 注册微信小程序
点击立刻注册，抉择微信小程序，依照要求填写信息
2. 登录小程序并欠缺信息
填写小程序信息，欠缺信息。
3. 下载小程序开发工具
欠缺信息后点击文档，工具，下载，抉择稳定版的对应平台的安装包下载，下载完后点击装置即可
4. 建设小程序我的项目
扫码登录，抉择小程序，并点击加号，填写相干信息，APPID 地位于下方截图所示。
5. 小程序代码构造介绍
如下图所示的四个文件，次要用于注册和配置微信小程序，其蕴含的是全局配置信息。
- app.js: 用于注册微信小程序利用。
- app.json: 小程序的全局配置，比方网络申请的超时工夫，以及窗口的属性
- app.wxss: 小程序全局款式
- project.config.json: 蕴含了小程序的整体配置信息，即便是换了开发设施，亦或是换了我的项目，只有将该文件保留，每个开发者的个性化设置就都将保留。
如下图所示，还有两个目录，
- pages：每一个子文件夹代表了小程序的一个页面，比方 index，和 logs 别离代表了两个页面。每个页面又由四个文件组成：
index.js：解决页面逻辑和数据交互。index.json：对应页面的配置信息。index.wxml：展现页面的内容和元素。index.wxss：设置用 wxml 展现元素的款式。 - utils：寄存的是一些工具代码，实现代码复用的目标。

开发试题分类页面
新增 home 页面
pages 目录下新建 home 目录，并增加 4 个文件，如图所示：
其中：
home.js
// pages/home/home.js
Page({data: {},
onLoad: function (options) { },
toTestPage: function(e){let testId = e.currentTarget.dataset['testid'];
wx.navigateTo({url: '../test/test?testId='+testId})
}
})home.wxml
<!--pages/home/home.wxml-->
<view class="page">
<view class="page-title"> 请抉择试题：</view>
<view class="flex-box">
<view class="flex-item"><view class="item bc_green" bindtap="toTestPage" data-testId="18">IT 常识 </view></view>

开发试题展现性能
新增 test 页面
pages 目录下新建 test 目录，并增加 4 个文件，如图所示：
批改 test.js
// pages/test/test.js
Page({
/**
* 页面的初始数据
*/
data: {test_id:0},
/**
* 生命周期函数 -- 监听页面加载
*/
onLoad: function (options) {this.setData({test_id:options.testId})
}
})
批改 test.wxml
<!--pages/test/test.wxml-->
<text> 我是{{test_id}}</text>
运行后果
在试题分类页点击某一分类，跳转到试题页，试题页显示分类 id

let options = {}
let optionArrShuffle = this.shuffle(optionArr)

}
const ordered_options = {};
Object.keys(options).sort().forEach(function (key) {ordered_options[key] = options[key];

"scores": 10,
"checked": false,
"option": ordered_options,
"true": optionArr[0]

});
return aTopicList;
},
这里解析的起因是，接口返回的 json 数据和咱们本人设计的数据格式略有不同，咱们要转换成本人的数据格式：
接口返回的数据格式：

开发期间：不校验非法域名，web-view….. 这里不要勾选。
引入第三方库
仔细的敌人可能会发现，有些题目中有乱码，如下图所示'：
有一个很好的第三方库 He 能够解决这个问题。
咱们须要应用 npm 导入一个第三方库解决这个问题，大家会学习到在小程序开发中如何应用 npm 引入第三方库。
我的项目根目录下新建 package.json 文件
{
"name": "wechatanswer-master",
"version": "1.0.0",
"description": "答题类微信小程序",
"main": "app.js",
"scripts": {"test": "echo \"Error: no test specified\"&& exit 1"},
"repository": {
"type": "git",
"url": "https://gitee.com/kamiba/my_quiz_wechat_app.git"
},
"author": "","license":"ISC","dependencies": {"he":"^1.2.0"}
}
2、执行 npm install –production xxx，这个 xxx 就是你想应用的 npm 包。此时在以后文件夹下会生成一个 node_modules 文件夹。PS：此处请务必应用 --production 选项，能够缩小装置一些业务无关的 npm 包，从而缩小整个小程序包的大小。
npm install --production he3、在微信开发者工具 –> 工具 –> 构建 npm，此时会生成一个 miniprogram_npm 文件夹。
4、构建实现后就能够应用 npm 包了。首先把应用 npm 模块勾起来，而后在 js 文件中引入即可。
而后批改 test.js
import he from "he";
// 主题列表数据模型
parseQuestion(aList) {let aTopicList = [];
if (!aList || (aList && !Array.isArray(aList))) {aList = [];
}
aTopicList = aList.map(oItem => {const answers = [oItem.correct_answer, oItem.incorrect_answers].flat()
let optionArr = ['A', 'B', 'C', 'D']
let options = {}
let optionArrShuffle = this.shuffle(optionArr)
for (let i = 0; i < answers.length; i++) {options[optionArr[i]] = he.decode(String(answers[i]));
}
const ordered_options = {};
Object.keys(options).sort().forEach(function (key) {ordered_options[key] = options[key];
});
return {"question": he.decode(String(oItem.question)), // id
"scores": 10,
"checked": false,
"option": ordered_options,
"true": optionArr[0]
};
});
return aTopicList;
},下面和以前有三处批改
import he from "he";
options[optionArr[i]] = he.decode(String(answers[i]));
"question": he.decode(String(oItem.question)), 计算用户得分，记录错题
批改 test.js

批改我的项目目录下的 app.json，减少底部导航栏

批改 pages 目录下 logs 页面

const util = require('../../utils/util.js')
Page({

// 拿到缓存并格式化日期数据
formatLogs: function(){let newList = [];
(wx.getStorageSync('logs') || []).forEach(log => {if(log.date){log['date'] = util.formatTime(new Date(log.date));
newList.push(log);

},最终我的项目构造
小程序部署上线
租用服务器，申请域名、搭建 Linux 环境并配置 https 服务
略
公布体验版
这里的体验版公布阶段有点相似于咱们日常的灰度公布前的外部灰度测试，能够指定白名单用户进行生产测试体验。公布的动作其实很简略，就是在微信的开发 IDE 中下面工具栏上点击上传按钮即可公布到微信服务器，提交后就能够在 mp 治理端查看到新的开发版本，能够公布二维码白名单用户扫码后进行体验。
上线审核
体验版本验证没问题后就能够公布，点击开发版本左边的提交审核按钮就能够公布到腾讯进行小程序审核，第一次公布审核工夫会比拟长，大概 3-5 个工作日左右，日后的降级版本审核就很快了，基本上能够做到半天就审核通过。
上线
审核通过后就会呈现在审核版本的栏位，点击左边的公布即可，公布后监控一段后盾服务状况，如果发现问题能够紧急回退版本，小程序 mp 治理端也提供了前端版本回退的性能。
总体来说小程序在版本治理、公布回退的体验方面做得还是很好的，可能满足根本需要，不须要额定的开发。
我的项目总结
很感谢您和豆约翰走到了这里，至此咱们这个常识测验微信小程序，全副开发结束。如果对于代码或小程序上线有任何疑难，能够加我微信 [tiantiancode] 一起探讨。
