项目需求：分享一篇微信文章，文章中嵌入图片和文字等。在文章的底部有一个二维码，用于扫描进入另一个页面去采集用户的报名数据。
实现步骤如下：
阶段一：微信公众号
1、申请一个微信公众号，由于考虑到是小范围使用，申请的是个人号
2、在‘素材管理’中，导入图片等信息。"图文消息"中去编辑微信文章。编辑完毕后保存
3、在“自定义菜单”项中去定义菜单，并将某个菜单指向为之前保存的“图文消息”
阶段二：信息采集功能开发
1、搭建一个空网站，安装插件：bootstrap、 jquery、bootstrapValidator。bootstrapValidator用作表单验证。
2、新建一个html页面，布局标签等信息。将提交的标签信息放置在form表单中。在表单标签中指定提交跳转的aciton，本项目指向一个一般处理程序：action="Handler.ashx" 完整代码如下：

4、由于返回的信息有显示格式要求，故需要将ContentType 的类型修改为 "text/html"
"text/plain"表示是普通文本，浏览器会原封不动的显示它得到的内容
"text/html"表示是超文本内容，浏览器会把它得到的内容按html格式进行处理后显示
5、数据库的链接串可以写在web.config配置文件中，然后在此处获取。
6、需要在一般处理程序中加入对数据库的操作ado语句，本项目使用的oracle，引入的dll文件名为Oracle.ManagedDataAccess.dll dll下载
7、将网站发布，部署到已准备好的服务器上面。
阶段三：网站域名的申请
1、由于在微信端访问无域名的网站（带ip）会提示是否继续访问的环节，使用体检差。故需要将服务器ip申请为域名
2、域名申请方式：买的阿里云域名。我是先在万网上购买了一个域名然后实名认证，再域名备案等等操作之后才可以使用。请自己去搜步骤
3、给域名绑定服务器ip，不支持+端口的绑定。故域名默认指向网站80端口
4、给网站绑定域名。截图如下：
5、绑定之后，就可以直接访问域名方式访问到网站
6、在微信公众号后台中去绑定域名
阶段四：将指定网页生成为二维码
1、复制网站地址，在“草料二维码”生成器中生成自己二维码，保存二维码为图片。
2、在微信素材管理中添加二维码图片，并在“图文消息”那篇文字最后放置二维码然后保存素材
结果：以上阶段完成后，将微信公众号中对应菜单分享给其他朋友就达到我们需求想要的效果.效果如下：
