##首先来看这个基本可无限拓展架构 这个架构从nginx反向代理开始 瓶颈 nginx反向代理服务器为瓶颈,其他层均可以进行无限拓展 ####nginx层 nginx配置反向代理和负载均衡使请求到相应的路由 ####路由层 路由层通过请求的URL或者其他参数来,使请求到指定的服务,通过负载均衡使请求到相对的服务上,部署多个路由当其中一个路由宕机之后也项目依然可以正常 ####服务层 相同的服务可以部署多个,配合路由层的负载均衡达到无限扩展,相同的服务部署多个,想其中一个或多个宕机之后项目依然可以正常使用 ####数据库层 数据库进行拆分成主从数据库进行数据同步保证数据的统一性 数据库分库:比方说用户系统,用户有ID 将 id取余1正好为0的放到一个库中 将id取余2位0的用户放到一个库中,依次类推,达到数据库层无限扩展的可能性 ####注册中心 所有的服务和路由都需要在注册中心注册,设置多个注册中心,当某个注册中心宕机之后服务依然可以正常 ####瓶颈 nginx是当前的瓶颈之一 使用session-cookie机制的话 session的存储比方说Reids之类的是瓶颈,这个可以采用JWT机制搞定 以上便是一个基本的可无限拓展架构,可以适用于当前大多数项目了 先这样吧,剩下的等哪次有空在写 ##一个基本升级的可以无限拓展架构 ##一个可以中等的可无限拓展架构 ##一个高级的无限拓展架构

微信内网页分享时,图片url不宜过长,否则会导致,分享到QQ的图片无法显示 $(function () { var config; var url = "[[@{/share/getJsShareConfig}]]" $.post(url, function (res) { res.data.debug = false; res.data.jsApiList = ['onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareTimeline', 'updateAppMessageShareData', 'updateTimelineShareData', 'translateVoice', 'checkJsApi']; $("#out").html("验证成功") config = res.data; wx.config(res.data); }); wx.ready(function () { console.log("验证成功"); }); wx.error(function (res) { console.log("验证失败"); }); layui.use(['form'], function () { var form = layui.form; form.on('submit(submit)', function (data) { var shareData = { title: data.field.title, desc: data.field.desc, link: 'http://xiaodingduang.com/share/redirect?url=' + data.field.url, imgUrl: data.field.imgUrl, success: function () { layer.alert("生成成功", { title: '提示' }) } } wx.updateAppMessageShareData(shareData); wx.updateTimelineShareData(shareData); return false; }); }) })

注意事项 微信支付时申请的 域名的备案主体 和微信公众平台 及微信商户平台的主体需要一致 如果不一致申请H5支付时需要提供其他补充材料,可能比较麻烦 微信H5支付 微信H5支付时必须企业账号才能审核通过

1.构建参数 Map<String, String[]> parameters = req.getParameterMap(); Map<String, String> parameterMap = new HashMap<>(); for (Object v : parameters.entrySet()) { Map.Entry<String, String[]> item = (Map.Entry<String, String[]>) v; parameterMap.put(item.getKey(), item.getValue()[0]); } 2.验证签名 这里有坑,官方给的代码中没有要求传入signType 参数,而代码中使用的是rsa算法 所以需要传入signType 将算法变为参数中的算法类型(rsa2) 公钥是支付宝公钥,非应用公钥,这是一个细节方面 String signType = parameterMap.get("sign_type"); if (AlipaySignature.rsaCheckV1(parameterMap, alipayPublicKey, "UTF-8", signType)) { return true; }
