微信公众号开发总结

最近公司用到了微信公众平台，所以研究了一下微信公众号的开发技术，总体来说比较简单，结合现有的平台核技术，实现起来非常方便。
首先先来了解一下微信公众平台。
“微信，是一个生活方式” ，这是微信的自我评价，是不是觉得如果那天不在朋友圈里分享一下自己的最新状态，
并且收到几个赞和评价的话，会觉得空虚寂寞呢？它实实在在的改变了我们的生活方式。
“ 微信，也是一个生意方式 ”，在微信成为我们日常必备之app的同时，它同样具备巨大的的商业
或许不应该称为潜力，因为有很多人已经获利，名人们在微信上开设公众账户来吸金，商家来做推广，
服务行业借此拓展渠道，甚至微信已经支持支付了, 还有越来越的自媒体在微信平台涌现出来。
这篇文章就是介绍如何快速的成为公众平台开发者，由于个人只能申请订阅号，因此本文是以订阅号为例。
关于订阅号和服务号的区别，请参见 微信公众平台服务号、订阅号的相关说明。
从微信用户角度简单来说:
订阅号 主要用于信息辐射，典型的如各家 新闻媒体 。
服务号 主要由于自助服务，典型的如 招商银行 。
申请公众平台账户
- 到 微信公众平台填写注册信息
- 按照提示激活邮箱
- 上传个人照片，需要有清晰的身份证照片
- 选择公众账户的类型，对于个人账户只能选择 订阅号
- 最后你会看到自己账户的所有信息，请上传账号的头像，否则无法完成开发者的申请
- 等待审核通过，这个过程大约需要2～3天，当你收到如下通知，那么恭喜你，你已经成功的申请到了微信公众账户了
关于微信公众帐号注册的步骤就不再多说了，可以找到大量的图文教程。
帐号注册成功之后，需要验证自己的服务器，如果你没有自己的服务器，那可以用新浪SAE或者百度BAE，本文采用的是新浪SAE平台来搭建服务器。
注册过程略，使用新浪SAE创建应用，可以选择应用开发框架，选项中有比较热门的开发框架，选择微信公众平台phpSDK，点击后跳转到介绍页面，点击安装框架，系统会生成一个搭建好的微信公众平台应用，为了方便开发，我们可以使用svn来管理此应用代码，关于svn搭建可参见sae代码部署手册。
使用新浪SAE是比较方便的，如果我们有自己的服务器，可以把代码clone到自己的服务器上，下面来看一下代码
首先定义一个Wechat的基类

以上代码部分功能需要开通服务号并且申请认证，比如语音识别，地理信息，添加菜单的功能，申请认证需要300元/年，可以享受微信所有的接口功能。
注：如果验证服务器URL，需要修改一句代码
<span $wechat</span> = <span new</span> MyWechat('hancong', <span TRUE</span><span );
</span><span //</span><span $wechat->run();</span>
<span $wechat</span>->validateSignature('hancong');<span //</span><span 参数为填写的token</span>Copier après la connexion
验证完后回复调用run方法，validateSignature方法只是第一次验证服务器调用，验证完后即可删掉。

Dix façons dont l'IA générative va changer le développement logiciel
Mar 11, 2024 pm 12:10 PM
Traducteur | Révisé par Chen Jun | Chonglou Dans les années 1990, lorsque les gens parlaient de programmation logicielle, cela signifiait généralement choisir un éditeur, vérifier le code dans la base de code CVS ou SVN, puis compiler le code dans un fichier exécutable. Les environnements de développement intégrés (IDE) correspondants tels qu'Eclipse et Visual Studio peuvent intégrer la programmation, le développement, la documentation, la construction, les tests, le déploiement et d'autres étapes dans un cycle de vie complet de développement logiciel (SDLC), améliorant ainsi l'efficacité du travail des développeurs. Ces dernières années, les outils populaires de cloud computing et d'automatisation DevSecOps ont amélioré les capacités complètes des développeurs, permettant ainsi à un plus grand nombre d'entreprises de développer, de déployer et de maintenir plus facilement des applications logicielles. Aujourd’hui, l’IA générative est le développement de la prochaine génération

Comment utiliser correctement et optimiser les performances des transactions du pool de connexions MySQL dans les programmes ASP.NET ? Dans les programmes ASP.NET, les transactions de base de données constituent une partie très importante. Les transactions garantissent la cohérence et l'intégrité de la base de données tout en offrant de meilleures performances. Lors de l'utilisation d'une base de données MySQL, il est essentiel d'utiliser un pool de connexions pour gérer les ressources de connexion et optimiser les performances. Tout d’abord, comprenons brièvement le concept de pool de connexions MySQL. Le pool de connexions est un pool tampon d'un groupe de connexions en pré-initialisant un certain nombre de connexions.
