不知道从哪个版本的 Chrome 或 Edge 开始，我们无法通过 ctrl+v 快捷键将时间格式的字符串粘贴到 type 为 date 的 input 框中，我们想办法用 JS 来实现。
方式一、监听 paste 事件：
const input = document.querySelector('input[type="date"]');
input.addEventListener('paste', (event) => {
input.value = event.clipboardData.getData('text');
});这段代码实现了从页面获取这个 input 元素，监听它的 paste 事件，然后将粘贴板的文本内容赋值给 input。
经测试，当焦点在“年”的位置时可以粘贴成功，但焦点在“月”或“日”上不会触发 paste 事件。
方式二、监听 keydown 事件：
const input = document.querySelector('input[type="date"]');
input.addEventListener('keydown', (event) => {
if ((navigator.platform.match("Mac") ? event.metaKey : event.ctrlKey) && event.key === 'v') {
event.preventDefault();
var clipboardData = (event.clipboardData || event.originalEvent.clipboardData);
input.value = clipboardData.getData('text');
}
});测试发现报错误：
Uncaught TypeError: Cannot read properties of undefined (reading 'getData')
Uncaught TypeError: Cannot read properties of undefined (reading 'clipboardData')
看来 event 中没有 clipboardData 对象，改为从 window.navigator 获取：
const input = document.querySelector('input[type="date"]');
input.addEventListener('keydown', (event) => {
if ((navigator.platform.match("Mac") ? event.metaKey : event.ctrlKey) && event.key === 'v') {
event.preventDefault();
window.navigator.clipboard.readText().then(text => {
input.value = text;
});
}
});缺点是需要用户授权：
仅第一次需要授权，如果用户拒绝，那么以后就默认拒绝了。
以上两种方式各有优缺点，选择一种适合你的方案就行。接下来继续完善。
兼容更多时间格式，并调整时区
<input type="date" /> 默认的日期格式是 yyyy-MM-dd，如果要兼容 yyyy-M-d 等格式，那么：
const parsedDate = new Date(text);
if (!isNaN(parsedDate.getTime())) {
input.value = parsedDate.toLocaleDateString('en-GB', { year: 'numeric', month: '2-digit', day: '2-digit' }).split('/').reverse().join('-');
}以 text 为“2023-4-20”举例，先转为 Date，如果成功，再转为英国时间格式“20-04-2023”，以“/”分隔，逆序，再以“-”连接，就变成了“2023-04-20”。
当然如果希望支持中文的年月日，可以先用正则表达式替换一下：
text = text.replace(/\s*(\d{4})\s*年\s*(\d{1,2})\s*月\s*(\d{1,2})\s*日\s*/, "$1-$2-$3");处理页面上的所有 <input type="date" />
const inputs = document.querySelectorAll('input[type="date"]');
inputs.forEach((input) => {
input.addEventListener(...);
});封装为独立域
避免全局变量污染，使用 IIFE 函数表达式：
(function() {
// 将代码放在这里
})();或者封装为函数，在 jQuery 的 ready 中，或 Vue 的 mounted 中调用。
在 Vue 中使用
如果将粘贴板的值直接赋值到 input.value，在 Vue 中是不能同步更新 v-model 绑定的变量的，所以需要直接赋值给变量：
<div id="app">
<input type="date" v-model="a" data-model="a" v-on:paste="fn_pasteToDateInput" />
{{a}}
</div>
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
<script>
const app = Vue.createApp({
data: function () {
return {
a: null,
}
},
methods: {
fn_pasteToDateInput: function (event) {
const text = event.clipboardData.getData('text');
const parsedDate = new Date(text);
if (!isNaN(parsedDate.getTime())) {
const att = event.target.getAttribute('data-model');
this[att] = parsedDate.toLocaleDateString('en-GB', { year: 'numeric', month: '2-digit', day: '2-digit' }).split('/').reverse().join('-');
}
},
}
});
const vm = app.mount('#app');
</script>示例中 <input /> 添加了 data- 属性，值同 v-model，并使用 getAttribute() 获取，利用 this 对象的属性名赋值。
如果你的 a 中还有嵌套对象 b，那么 data- 属性填写 a.b，方法中以“.”分割逐级查找对象并赋值
let atts = att.split('.');
let target = this;
for (let i = 0; i < atts.length - 1; i++) {
target = target[atts[i]];
}
this.$set(target, atts[atts.length - 1], text); // vue2
target[atts[atts.length - 1]] = text; // vue3

新版本 SDK 已解决这个问题
升级到 .NET 7 后，Senparc.Weixin 6.15.7 正常，6.15.8.1-6.15.8.3 无法正常启动，行
builder.Services.AddSenparcWeixinServices(builder.Configuration);报错：
System.NullReferenceException:“Object reference not set to an instance of an object.”临时解决方法，改为：
builder.Services.AddSenparcWeixinServices(builder.Configuration, delegate { });a

本文使用 ASP.NET 6 版本 Senparc.Weixin.Sample.MP 示例项目改造。
第一步 注册多公众号
方法一：打开 appsettings.json 文件，在 SenparcWeixinSetting 节点内添加数组节点 Items，该对象类型同 SenparcWeixinSetting。
//Senparc.Weixin SDK 设置
"SenparcWeixinSetting": {
"IsDebug": true,
"Token": "",
"EncodingAESKey": "",
"WeixinAppId": "",
"WeixinAppSecret": "",
"Items": [
{
"IsDebug": true,
"Token": "a",
"EncodingAESKey": "a",
"WeixinAppId": "a",
"WeixinAppSecret": "a"
},
{
"IsDebug": true,
"Token": "b",
"EncodingAESKey": "b",
"WeixinAppId": "b",
"WeixinAppSecret": "b"
}
]
}方法二：修改 Program.cs 文件，在 UseSenparcWeixin 方法中注册多个公众号信息。
var registerService = app.UseSenparcWeixin(app.Environment,
null /* 不为 null 则覆盖 appsettings 中的 SenparcSetting 配置*/,
null /* 不为 null 则覆盖 appsettings 中的 SenparcWeixinSetting 配置*/,
register => { /* CO2NET 全局配置 */ },
(register, weixinSetting) =>
{
//注册公众号信息（可以执行多次，注册多个公众号）
//register.RegisterMpAccount(weixinSetting, "【盛派网络小助手】公众号");
foreach (var mp in 从数据库或配置文件中获取的公众号列表)
{
register.RegisterMpAccount(new SenparcWeixinSetting
{
//IsDebug = true,
WeixinAppId = mp.AppId,
WeixinAppSecret = mp.AppSecret,
Token = mp.Token,
EncodingAESKey = mp.EncodingAeskey,
}, mp.Name);
}
});完成后，我们可以从 Config.SenparcWeixinSetting.Items 获取这些信息。
第二步 接入验证与消息处理
打开 WeixinController 控制器，将构造函数改写为：
public WeixinController(IHttpContextAccessor httpContextAccessor)
{
AppId = httpContextAccessor.HttpContext!.Request.Query["appId"];
var MpSetting = Services.MPService.MpSettingByAppId(AppId);
Token = MpSetting.Token;
EncodingAESKey = MpSetting.EncodingAESKey;
}示例中 Services.MPService.MpSettingByAppId() 方法实现从 Config.SenparcWeixinSetting.Items 返回指定 appId 的公众号信息。
为使 IHttpContextAccessor 注入生效，打开 Program.cs，在行
builder.Services.AddControllersWithViews();下方插入
builder.Services.AddHttpContextAccessor();这样，我们就可以在构造函数中直接获取地址栏中的 appId 参数，找到对应的公众号进行消息处理。
第三步 消息自动回复中的 AppId
打开 CustomMessageHandler.cs，将
private string appId = Config.SenparcWeixinSetting.MpSetting.WeixinAppId;
private string appSecret = Config.SenparcWeixinSetting.MpSetting.WeixinAppSecret;替换为：
private string appId = null!;
private string appSecret = null!;并在构造函数中插入
appId = postModel.AppId;
appSecret = Services.MPService.MpSettingByAppId(postModel.AppId).WeixinAppSecret;这样，本页中使用的 appId / appSecret 会从 postModel 中获取，而非默认公众号。postModel 已在 WeixinController 中赋值当前的 appId。
改造后，我们可以在 OnTextRequestAsync() 等处理消息的方法中可以判断 appId 来处理不同的消息。
第四步 其它功能和接口
其它功能和接口均可用指定的 AppId 和对应的 AppSecret 进行调用。

* 若服务端获取参数值为 null，可能的情况如下：
请检查相关枚举类型是否已设置 [JsonConverter] 属性，参：C# 枚举（enum）用法笔记，且传入的值不能为空字符串，可以传入 null 值，并将服务端 enum 类型改为可空。可以以 string 方式接收参数后再进行转换。
模型中属性名称不能重复（大小写不同也不行）。
布尔型属性值必须传递布尔型值，即在 JS 中，字符串 "true" 应 JSON.parse("true") 为 true 后再回传给服务端，vue 绑定方式参此文。

1075 - Incorrect table definition; there can be only one auto column and it must be defined as a key
在 MyISAM 转 InnoDB 时出现。
原因：这个表有联合主键，且自增的字段不是第一个主键。
解决方法一，取消自增字段的自动递增，改为在程序中实现；
解决方法二，单独给自增字段单独添加一个索引。
以 Disucz! X3.4 为例，方法一改程序代码显然困难比较大，所以选择方法二。
表 pre_forum_post 中，tid 为第1主键，position 为第2主键且自增。
tid 表示主题，position 表示该帖在该主题中的位置（类似于楼层的概念）。
所以在原来 MyISAM 中可以方便地实现 position 在各自的主题下自增。
给 position 单独添加索引后可以将引擎改为 InnoDB，但是 position 在全表范围内自增了。
也就是说，如果发布一个新主题，那么这个主题帖的 position 就不是1，而是整个数据库中最大的 position 再加 1。
虽然不影响页面中帖子的排序和楼层号显示，但不知道会不会有其它问题，所以最好把它改过来。
给表 pre_forum_post 添加一个触发器，在插入前（BEFORE INSERT）
BEGIN
DECLARE max_position INT;
SELECT MAX(position) INTO max_position FROM pre_forum_post WHERE tid = NEW.tid;
IF max_position IS NULL THEN
SET max_position = 0;
END IF;
SET NEW.position = max_position + 1;
END在上面触发器的定义中，NEW 指即将要插件的一条记录，在新插入的帖子所在主题中寻找最大的 position 赋值给一个 INT 变量，如果找不到就赋值 0，然后 +1 赋值给新的 position。
这样就实现了与原来相同的效果。
用同样的方法给表 pre_common_member_grouppm 添加触发器。
如果帖子有分表，给每个分表添加触发器，下次有新的分表也要记得添加。
