1 | ### wechat-app-issues
2 |
3 | 早就知道小程序这个坑很深，一个多月的实践发现这个坑果然名不虚传...
4 |
5 | 不过，开发的小程序如期上线了，还是值得庆贺！！！呵呵，记录一下那些让自己停顿的点。
6 |
7 | #### 一、开发微信小程序遇到的坑
8 |
9 | - 1、 {{}} 不能执行方法，只能处理简单的运算如 “+ - * /”，比如遇到遍历list，每个item的金额需要格式化，只能在js里预先格式化好再setData一遍( ╯□╰ )
10 | - 2、只能通过,只能通过,只能通过setData()更新视图，坑..........
11 | - 3、我们规定页面路径只能是五层，请尽量避免多层级的交互方式。
12 | - 4、A页面-->B页面，B页面返回A，如何触发A的刷新，不增加页面层级。
13 | 暂时想到的方案：在A页面的onshow事件里写A的初始化数据逻辑。
14 | - 5、undefined 当作字符串处理 if(xxx == "undefined") 【后期版本迭代优化了】
15 | - 6、遇到奇怪的问题（如样式等）先重启工具，百试不爽
16 | - 7、不支持本地web字体(需要使用线上字体),经测试发现一些安卓就是不能正常显示。几经折腾才发现原来还要存放字体的服务器要支持跨域。尼玛，手机上调试也不报错，差点放弃web字体了。卡了好久，坑.............
17 | - 8、本地资源无法通过 css 获取 可以使用网络图片，或者 base64，或者使用 `` 标签
18 | - 9、不能直接操作 Page.data 【避免在直接对 Page.data 进行赋值修改，请使用 Page.setData 进行操作才能将数据同步到页面中进行渲染】
19 | - 10、数字键盘用 type="digit"
20 | - 11、已用 https，但报无法建立与该服务器的安全连接是什么情况【需要 nginx 配置一下 https 的加密标准为tls1.2及以上】
21 | - 12、wx.setStorage(OBJECT) 【目前每个小程序限制5M】
22 | - 13、数据监控【微信后台：事实访问次数/昨日概况/累计访问用户数/TOP受访页】
23 | - 14、微信调试神器，ngrok，见 ngrok
24 | - 15、view 添加点击效果[需要开启hover效果]：
25 |
26 | ```html
27 |
28 | ```
29 | - 16、用户授权调试方法【开发工具-》清除手机授权数据 (缓存-清除手机授权数据) 】
30 | - 17、安卓手机上小程序第一次加载时候首页时候， onshow方法会莫名其妙加载两遍，而同样在iphone下却不会，由于需要在onshow里面触发获取用户信息，所以系统加载两次onshow会导致后台报错。。。
31 | - 18、禁止页面下拉： 设置 "disableScroll": true 。
32 | - 19、安卓下会出现getAppConfig:fail，无法获取userInfo。微信问题，下载最新的微信安装包
33 | - 20、后台不能接受POST数据，但是可以接收GET请求参数
34 |
35 | ```json
36 | url: url,
37 | data: data,
38 | method: "POST",
39 | dataType: "json",
40 | header: {
41 | 'content-type': 'application/x-www-form-urlencoded' //==> 此处若为application/json则服务端无法获取POST的参数
42 | }
43 | ```
44 |
45 | - 21、小程序第一次启动用户拒绝授权后，下一次无法唤起授权弹框，默认记住上一次用户的选择。暂时没有找到解决方法，微信也没有相关解析。【2017-01-10】
46 | 微信更新了api（wx.authorize(OBJECT)）,支持唤起授权弹框【2017-07-05】
47 | - 22、跳转到有tabbar的页面一定要用 wx.switchTab().这个在各个群里几乎每天都有人问到！！！
48 | - 22、绑定开发者/体验者时记得去手机上确认邀请。（超多人问）
49 |
50 | 
51 |
52 | - 23、 微信后台更新了request合法域名，可以直接去微信开发工具-->项目-->配置信息-->刷新，立马生效。
53 | - 24、 小程序官方没有提供java版登录信息解密示例，可以用这个demo java版解密demo
54 | - 25、 使用wx:for遍历的时候最好加上wx:key="{{item.id}}"，如果明确知道该列表是静态，或者不必关注其顺序，可以选择忽略，但是如果遍历的数组会发生改变，则有可能导致数据顺序会改变。
55 |
56 | 
57 |
58 | - 26、小程序开发页面便利之处在于rpx, 所以设计稿建议用iphone6尺寸。flex布局可以参考这篇
59 | - 27、微信小程序的会默认监听文件变化，然后自动刷新。但不足的是每次都是全量刷新，而不是模块的热替换，反而会影响开发速度，尤其对于喜欢频繁Command + S的开发者，你会发现你的小程序在不断的刷新。[@MinJieLiu](https://github.com/MinJieLiu)
60 | - 28、微信小程序自 基础库 `1.6.4 `开始支持了`web-view`组件，即在小程序支持了嵌入网页的能力，但是使用的时候发现在开发者工具中不能显示网页，手机预览却可以【升级微信客户端最新版本】。原因是所使用的基础库不支持`web-view`组件，可通过选择最新的基础库解决。如下：
61 |
62 | 
63 |
64 | - 29、 不支持H5和小程序通信，不能通过本地存储之类的手段打通， 如果硬是需要携带参数，可以尝试在`web-view` url 中携带，但是不推荐，H5可以使用公众号授权。web-view开放的能力（网页需嵌入jssdk）： [网页中支持的JSSDK接口](https://mp.weixin.qq.com/debug/wxadoc/dev/component/web-view.html)：
65 | - 30、web-view 目前不支持微信支付
66 | - 31、小程序中`try...catch`语句中`catch`部分使用`throw`抛出错误在更外层的`try...catch`无法捕获到
67 |
68 | 
69 |
70 | #### 二、小程序开发前相关配置
71 |
72 | - 1、登录--->管理员扫二维码-->设置-->开发设置-->生成AppSecrect
73 | - 2、服务器配置
74 | 登录--->管理员扫二维码-->设置-->开发设置-->服务器域名-->扫二维码
75 | - 3、绑定开发者
76 | 用户身份-->开发者-->二维码 开发者最多10人
77 | - 4、绑定体验者
78 | 用户身份-->体验者-->二维码扫描 体验者20人
79 |
80 |
81 | #### 三、小程序发布
82 |
83 | 发布只能用管理员账号。步骤如下：
84 |
85 | - 开发工具中退出开发者账号
86 | - 管理员扫码登录开发者工具，上传-->微信后台设为体验版本-->审核-->发布
87 |
88 | 注意： 审核时间不定，2-6天
89 |
90 | #### 四、审核不通过原因收集
91 | - 1、小程序简介没有介绍小程序功能
92 | - 2、类目与页面提供的内容不一致
93 | - 3、小程序提供的服务和内容必须是正式的，不能以测试内容提交，多次以测试内容提交
94 | - 4、含有声音视频内容，请补充相关对应类目
95 | - 5、首页图片与文字有互相重叠，建议优化
96 | - 6、搜索框及少数下才能选中，页面评论点击无响应，页面图片分辨率尺寸失真
97 | - 7、部分图片显示被压缩体检不好
98 | - 8、有账号体系的小程序，除自有登录方式，必须支持微信授权登录
99 | - 9、必须登录才能使用的服务，请提供测试账号
100 | - 10、存在虚拟物品在线交易， ios系统需要走IAP,小程序暂不支付，请留意后续
101 | - 11、小程序服务类目所对应的页面中的核心内容必须与该类目一致。
102 | - 12、必须保证用户在该页面能使用该服务类目，不得隐藏，不得进行多次跳转
103 | - 13、不得展示和推荐第三方小程序。示例：不能做小程序导航，不能做小程序链接互推，小程序排行榜等
104 | - 14、小程序的页面内容中，存在诱导类行为，包括但不限于诱导分享、诱导添加、诱导关注公众号、诱导下载等，要求用户分享、添加、关注或下载后才可操作的程序，含有明示或暗示用户分享的文案、图片、按钮、浮层、弹窗等的小程序，通过利益诱惑诱导用户分享、传播的小程序，用夸张言语来胁迫、引诱用户分享的小程序，强制或诱导用户添加小程序的，都将会被拒绝；
105 | - 15、 禁止视频、音乐、语音等多媒体的自动播放
106 | - 16、 如果小程序有账户系统，必须提供能正常使用且易于发现的“退出”账户选项
107 | - 17、小程序内容不能包含赌博、竞猜和抽奖的。
108 | - 18、小程序的页面内容中，不能存在测试类内容；示例：算命，抽签，星座运势等。

118 |
119 | #### 六、code
120 |
121 | - 1、封装微信发起请求接口,登录失效默认自动发起登录请求
122 |
123 | ```js
124 | /**
125 | * 发起的是 HTTPS 请求
126 | * @pram url: 请求地址,协议必须为https
127 | * @pram data 请求参数请求参数
128 | * @param success 请求成功回调
129 | * @param fail 请求失败回调
130 | * @param complete 请求完成（成功或者失败）回调
131 | */
132 | function request(url, data, success, fail, complete) {
133 | var _url = url,
134 | _data = data,
135 | _success = success,
136 | _fail = fail,
137 | _complete = complete;
138 |
139 | wx.request({
140 | url: url,
141 | data: data,
142 | method: "POST",
143 | dataType: "json",
144 | header: {
145 | 'content-type': 'application/x-www-form-urlencoded',
146 | 'Client-Agent': getSystemInfo(),
147 | 'WX-SESSION-ID': wx.getStorageSync(constant['WX-SESSION-ID']) //每次请求带上登录标志
148 | },
149 | success: function(res) {
150 | if(res.data.code == "-9999") { //会话失效重新登录
151 | requestLogin(function(){
152 | constant['NUM_TRY_LOGIN'] ++;
153 | //设置请求上限，防止重复提交并死循环
154 | if(constant['NUM_TRY_LOGIN'] < constant['LIMIT_NUM_TRY_LOGIN']) {
155 | request(_url, _data, _success, _fail, _complete);
156 | }
157 | });
158 | return;
159 | }
160 | if(res.data.code == "0") {
161 | if(typeof _success == "function") {
162 | _success(res.data);
163 | }
164 | } else {
165 | wx.showToast({title: res.data.msg, icon: 'loading', duration: 2000});
166 | return;
167 | }
168 | },
169 | fail: function(res) {
170 | if(typeof _fail == "function") {
171 | _fail(res);
172 | }
173 | if(typeof _fail == "string") { //请求失败的弹框提示
174 | wx.showToast({title: _fail, icon: 'loading', duration: 2000});
175 | }
176 | },
177 | complete: function(res) {
178 | if(typeof _complete == "function") {
179 | _complete(res);
180 | }
181 | }
182 | });
183 | }
184 | ```
185 | - 2、请求登录接口
186 |
187 | ```js
188 | /**
189 | * 请求登录,获取用户相关信息
190 | * @param callback
191 | */
192 | function requestLogin(callback) {
193 | var _callback = callback;
194 | wx.login({
195 | success: function (event) {
196 | // 获取到请求码，继续请求用户的基本信息
197 | if(event.code) {
198 | var code = event.code;
199 | wx.getUserInfo({
200 | success: function (res) {
201 | var data = {
202 | code: code,
203 | encryptedData: res.encryptedData,
204 | iv: res.iv,
205 | signature: res.signature,
206 | rawData: res.rawData
207 | }
208 | var url = domain + "/wx_xxx"; //请求登录地址
209 | request(url, data,
210 | function(res){ //success
211 | if(res.code == "0") {
212 | //此处可以将服务端返回的登录状态保存起来
213 | wx.setStorageSync(constant['WX-SESSION-ID'], res.object.sessionId);
214 | if(typeof _callback == "function") {
215 | _callback();
216 | }
217 | }
218 | },
219 | function(res){ //fail
220 | wx.showToast({title: '请求登录失败',icon: 'loading', duration: 2000});
221 | }
222 | );
223 | },
224 | fail: function(res) {
225 | //用户拒绝授权
226 | if(res.errMsg == "getUserInfo:cancel" || res.errMsg == "getUserInfo:fail auth deny") {
227 | wx.redirectTo({ //跳转至未授权页面
228 | url: '../xxx-page/xxx-page'
229 | });
230 | }
